M I C H I G A N 1949 All Rights Reserved American Academy of Osteopathy® FOREWORD The first paper in this Year Book for 1949 written and illustrated by Dr. Howard A. Lipplncott describes a unique and most valuable type of osteopathic technic developed by Dr. William G. Sutherland, the discoverer and nationally known teacher of Cranial Osteopathy. This technic is based on the same principle of respiratory cooperation on the part of the patient which plays such an Important role in Cranial Osteopathy. Without doubt Dr. William G. Sutherland has made the greatest single contribution to the advancement of manipulative osteopathy since Dr. Andrew Taylor Still established it three quarters of a century ago and in recognition of his great contribution to the osteopathic profession we affectionately dedicate this 1949 Year Book to him. Aside from the usual group of papers from the Annual Convention and solicited contributions we are reprinting several basic articles by permission that appeared some years ago in the Journal of the American Osteopathic Association by the late Dr. Charles Hazzard and Dr. Albert E. Guy. Dr. Anne L. Wales has also written a review and digest of a most valuable contribution by Dr. Carl E. McConnell which appeared in the Journal in April 1905. Consistent with the main objective of the Academy of Applied Osteopathy which from the beginning has been to help develop manipulative therapy to a higher plane of usefulness and a more scientific application in the treatment of disease, the Academy has inaugurated a program of Post Graduate Osteopathic Training Courses, the first of which was given at Oakland, California, December 28-31, 1948 and It is the purpose of the Publication Committee to include in this and succeeding Year Books such material as will best support this program. We are privileged to include in this book several lectures by Dr. Perrin T. Wilson and Dr. C. Haddon Soden that were given last June before the British Osteopathic Association as a part of a two weeks Post Graduate Course. Every effort is being made to improve the quality of the Year Book. -More papers are being solicited and more of them edited. However, it is the purpose of the Publication Committee to continue to print individual clinical observations and technical developments for the benefit of our membership. We accept these individual opinions and observations as an effort on the part of the author to be of service to the profession without endorsement by the Academy or the American Osteopathic Association being given or implied. Such papers are to be considered as preliminary reports and the author should be credited with the same sincerity of purpose and integrity as one would wish to be accorded under similar circumstances. It seems better to publish some of these papers as they are presented and unedited rather than to risk the loss of a valuable observation because the editor does not grasp the full import of the observation. The usual geographic listing of Academy members and Academy reports have been omitted as It is planned to issue a complete Annual Report and Directory of members at the close of the fiscal year. An alphabetical list of members as of December 20, 1948 will be found at the back of the book. Our sincere appreciation to all who have cooperated by providing material for this book and to the members of the Publication Committee for their help in preparing manuscripts. We feel keenly the loss of Dr. Ralph W. Rice from the Publication Committee by his untimely death. This is the first book in several years which has not carried a good number of photographs taken by him. Appreciation Is due Miss Mary P. Boniface for typing of manuscripts and proofreading.

G. SUTHERLAND, D.O. H. A. Lippincott, D.O. At the time that Dr. Sutherland received his osteopathic training at Kirksville Dr. Andrew Taylor Still was carefully supervising all the instruction given at the college. The principles that were taught had to conform exactly to his concept. Dr. Sutherland made good use of every opportunity to learn and understand them and has adhered closely in his thinking and practice to Dr. Still's principles throughout his professional career. In consequence the technique which he has presented to us is a reflection of the clear vision of our founder. In these days of rapid changes in medicine older methods are constantly being replaced by the new and there is scoffing at the procedures that were used in the day of our grandfathers. On the other hand, the changes in the human structure, due to environment, are such that it is now even more susceptible to the strains that were considered by Dr. Still to be the most important cause of disease. Physical response to various types of osteopathic treatment is essentially the same now as in the nineteenth century. The technique presented here is of more than historical interest, it is of real practical value in our everyday work. General Considerations Ligamentous Articular Strains Osteopathic lesions are strains of the tissues of the body. When they involve joints it is the ligaments that are primarily affected so the term "ligamentous articular strain" is the one preferred by Dr. Sutherland. The ligaments of a joint are normally on a balanced, reciprocal tension and seldom if ever are they completely relaxed throughout the normal range of movement. When the motion is carried beyond that range the tension is unbalanced and the elements of the ligamentous structure which limit motion in that direction are strained and weakened. The lesion is maintained by the overbalance of the reciprocal tension by the elements,which have not been strained. This locks the articular mechanism or prevents its free and normal movement. The unbalanced tension causes the bones to assume a position that is nearer that in which the strain was produced than would be the case if the tension were normal, and the weakened part of the ligaments permits motion in the direction of the lesion in excess of normal. The range of movement in the opposite direction is limited by the more firm and unopposed tension of the elements which had not been strained. Principles of Corrective Technique Since it is the ligaments that are primarily involved in the maintenance of the lesion it is they, not muscular leverage, that are used as the main agency for reduction. The articulation is carried in the direction of the lesion, exaggerating the lesion position as far as is necessary to cause the tension of the weakened elements of the ligamentous structure to be equal to or slightly in excess of the tension of those that were not strained. This is the point of balanced tension. Forcing the joint to move beyond that point adds to the strain which is already present. Forcing the articulation back and away from the direction of lesion strains the ligaments that are normal and unopposed, and if it is done with thrusts or jerks there is definite possibility of separating fibers of the ligaments from their bony attachments. When the tension is properly balanced the respiratory or muscular cooperation of the patient is employed to overcome the resistance of the defense mechanism of the body to the release of the lesion. If the patient holds the breath in or out as long as possible there is a period during his involuntary efforts to resume breathing when the release takes place. In appendicular lesions the patient holds the articulation in the All Rights Reserved American Academy of Osteopathy® 2 position of exaggeration and the release occurs through the agency of the ligaments when or just before the muscles are relaxed. There are exceptions to the general principle of correction by exaggerating the lesion position. The disengagement method, with the rib technique as an example, uses a fulcrum upon which a leverage tends to separate the bony surfaces and tense the ligamentous connections. This method is combined with exaggeration of the lesion position in treatment of the long bones of the extremities. Under some circumstances it is unwise to add tension to the involved ligaments, as in the case of a severe strain of recent production. In that event the pain will be increased under exaggeration and the correction is made by holding the more distal bone in the direction of the normal position while the patient participates by gently and slowly moving the proximal bone toward its proper relationship. This is known as "direct action" technique. It is used in the postural sacroiliac or iliosacral lesion in which the irregularity of the auricular surfaces prevents a wide range of motion, especially on the axis through the second sacral segment. The participation of the patient in the technique is a matter of importance. If the operator holds the bone which is in lesion and the patient moves the one upon which it is lesioned there is less likely to be undue strain placed upon the ligaments than if the operator exerts the force necessary to accomplish a reduction. Con-� sidering the lesioned bone as the 'bolt' and the one proximal to it as the 'nut', it is a better mechanical principle for the operator to hold the bolt and allow the patient to turn the nut than for the operator to turn the bolt. The physical equipment needed for this technique is simple. An osteopathic table, a stool and a chair are the main items. Mention is made of use of the Ritter stool in some of the procedures. It is a stool that tilts from the base, the seat turns and is adjustable for height. The stool is made with a minimum height of twenty one inches for use in this work. Of greatest importance, however, is the mental equipment of the operator, his ability to visualize the structures concerned in the lesion, and the keen tactile sense common to osteopathic physicians. Cervical Vertebrae From the axis to the seventh cervical vertebra the articular surfaces lie in a plane that is tipped anteriorly from the coronal, so in flexion the articular processes of one vertebra move upward and forward in relation to the one below and in rotation sidebending the movement is in that direction on the side that is anterior and convex. In extension the articular processes move relatively downward and posteriorly as does the one on the posterior and concave side in rotation sidebending. The anterior convexity of the cervical curve is reduced or straightened when the neck is bent forward in flexion, increasing the distance from the occiput to the shoulders. That distance is also increased on the anterior side in rotation sidebending and is reduced in extension as well as on the posterior side in rotation sidebending. The technique for correction of cervical ligamentous articular strains makes use of those principles. The articular processes that are relatively anterior or that move anterosuperiorly more easily are held anterosuperiorly to balance the tension of the capsular ligaments and the shoulders of the patient are placed so that the lesion position is exaggerated. The manner in which the patient holds the neck, especially in acute lesions, and the altered bony relationships and soft tissue pathology noted under palpation give evidence of the location and type of lesion. The determining factor, however, is the freedom or restriction of motion. The articulation moves more freely and usually with less discomfort to the patient in the direction of the lesion than in the opposite direction. The technique is best applied with the patient supine and relaxed, but when circumstances do not permit this the physician can use his ingenuity in adapting the technique to the position that can be assumed. It is said that Dr. Still, meeting a patient on the street, would even stand him against a tree to reduce a sacroiliac lesion. There is considerable latitude in applying Dr. Sutherland's technique providing the underlying principles are not violated. The position of the shoulders is All Rights Reserved American Academy of Osteopathy® 3 Fig. 1. Cervical Technique In this case the fingers are crossed to contact the articular processes on the opposite side. taken without appreciable strain or tension of the musules, the purpose being only to affect the ligamentous tension by altering the relative position of the attachments of the ligaments. Flexion Lesions The articular processes of the upper of the two vertebrae involved are held anterosuperiorly by the tips of the operator's fingers, the direction being in the plane of the articular surfaces. The patient lowers both shoulders toward the hips avoiding any abduction of the arms. The point of balanced tension is found by the operator and held during respiratory cooperation in inhalation which also tends to reduce the anterior convexity of the cervical spine. Extension Lesions These are corrected with the processes of the lower of the two vertebrae held anterosuperiorly, the patient's shoulders moved cranialward, and respiratory cooperation in exhalation. Rotation Sidebending Lesions The articular process of the upper vertebra on the side of convexity is relatively anterosuperior and it is held in that direction by the operator. The one on the opposite side of the vertebra below is held anterosuperiorly under the inferior facet of the upper one which is relatively posterior and downward. The shoulder is lowered on the side of convexity to increase the separation of the facets and the opposite one is elevated to carry the superior process of the lower vertebra anteriorly and upward. The patient holds the breath either in or out, sometimes depending on whether the strain is greater where the articular processes are Separated or approximated. Respiratory cooperation follows the general rule that inhalation is associated with flexion and external rotation, exhalation with extension and internal rotation. The point of balanced ligamentous tension may be rather elusive, making it necessary to slightly alter the degree of pressure on the articular processes or the height of the shoulders. The greater strain may be in the ligaments of either one side or the other, so the tension may have to be varied to attain balance. Condyloatlantal Lesions The articular pits of the atlas converge anteriorly and inferiorly and they curve cranialward to a position anterior to the occipital condyles. The motion permitted is a nodding of the head as the condyles rock forward and back in the cupshaped pits of the atlas. Correction of the condyloatlantal lesion Is made with the patient supine as the position of choice. The operator places the tip of a finger against the posterior tubercle of the atlas and holds that bone anteriorly to prevent it from moving dorsally with the condyles as the patient nods or tips his head forward, avoiding flexion of the cervical spine. This rocks the occiput posteriorly in the pits, releasing the condyles from the atlas, and tenses the ligaments. The right and Fig. 2. Condyloatlantal All Rights Reserved American Academy of Osteopathy® 4 left articulations will find a point of balance between them, perceptible to the operator as a slight springing or elastic resistance of the ligaments. This position is held while the patient holds the breath in either inhalation or exhalation. Release of the fixation is frequently perceptible to both the patient and the operator, usually during the respiratory efforts just before the patient must resume breathing. This technique is effective whether the lesion be unilateral or bilateral, or the condyles be held in the anterior, posterior or lateral position. Atlanto-Axial Lesions Dr. Sutherland finds that ligamentous strains of the atlanto-axial articulation frequently become apparent following the successful reduction of those of the condyloatlantal articulation, indicating that they are of a compensatory nature. It occurs to him that the ligamentous agencies of that region function somewhat in the manner of the hairspring of the balance wheel of a watch, causing motion of the occiput to be reciprocated between the atlas and axis. Although the articular structure and the motion are quite different from those of the typical cervical vertebrae, the tech nique is similar. In arriving at a ligamentous balance between the atlas and axis it is to be remembered that the motion is almost entirely rotation with little sidebending and that the superior facets of the axis face cranialward and laterally. The shoulder and respiratory cooperation are employed as in the technique for lesions of the typical cervical articulations. Thoracic the upper one moves dorsally. Elevation of the shoulders tends to separate the transverse processes and move the inferior articular facets anterosuperiorly on the superior articular surfaces of the vertebra below, approximately the relationship which exists during flexion. When the shoulders are lowered the articular processes assume the relationship present in extension. Elevating one shoulder separates the transverse processes on that side and the upper one moves anteriorly, as on the side of convexity in sidebending rotation, while lowering of the shoulder produces the relationship which is present on the side of the concavity. Technique for the correction of thoracic vertebral lesions employs cooperation by the patient based on these principles. Palpation for Motion With the patient seated or supine the operator places a finger on each transverse process of the vertebra in question. The patient elevates the shoulders slowly, then lowers them toward the hips, then raises one and lowers the other alternately while the operator palpates for freedom of motion. The location and direction of the strain having been ascertained, the transverse processes of the involved vertebrae which (processes) are in the relatively anterior position are held anteriorly in the plane of the articular facets to exaggerate the lesion position. Vertebrae The facets of the superior articular processes face dorsally, cranially and laterally, those of the inferior processes facing ventrally, caudally and medially. Consequently in flexion the transverse processes of one vertebra move anteriorly and superiorly in relation to those of the one below, and in extension, posteroinferiorly. In sidebending rotation the transverse process on the side of convexity moves cranially, anteriorly and slightly medially away from the one below and on the side of concavity the two processes approximate and Fig. 3. Thoracic vertebra The transverse process on only one side may be ield anterosuperiorly for exaggeration of the lesion position. All Rights Reserved American Academy of Osteopathy® Flexion Lesions The processes of the upper of the two vertebrae are held anterosuperiorly while the patient elevates both shoulders to balance the ligamentous tension as determined by the operator. This position is held while the patient inhales and holds the breath. Extension Lesions Extension lesions are corrected with the transverse processes of the lower of the two vertebrae being held anterosuperiorly, and the patient's shoulders lowered. Respiratory cooperation is in exhalation. Sidebending Rotation Lesions On the side of convexity the transverse process of the upper vertebra and on the concavity that of the lower one are held anterosuperiorly. The patient elevates the shoulder on the side of convexity, lowers the other one and carries it slightly posteriorly. The point of balanced tension is found, and the respiratory cooperation may be in either inhalation or exhalation, - inhalation if the ligamentous imbalance is mainly on the side of convexity and exhalation if on the concavity. Patient on Knees of - Operator In another method of correcting tho racic vertebral lesions the patient is seat ed on the knees of the operator, or on a Ritter stool, facing the table. The forearm of the operator holds the patient's pelvis posteriorly. The patient rests his elbows on the table and walks or inches forward with them to carry the inferior 5 articular processes craniad in relation to the superior ones of the vertebra below. The operator palpates at the transverse process for limitation of motion and for-the point of balanced ligamentous tension. Flexion If the lesion is of the flexion type a finger on each transverse process of the upper of the two vertebrae lightly encourages their anterosuperior movement while palpating for the proper degree of separation from the vertebra below as the patient steps forward with his elbows on the table. When that point is reached the correction is accomplished with the patient holding the breath in inhalation. Extension The operator's fingers areplaced on the transverse processes of the lower of the two vertebrae involved, the patient steps forward with his elbows until that vertebra is felt to move upward. The transverse processes are then held gently in an anterosuperior direction while the patient steps backward with his elbows for an inch or two. This carries the articular processes of the upper of the two vertebrae back to exaggerate the extension position at he point of lesion. The correction is mad during exhalation. Sidebending Rotation In correcting these lesions the forearm of the operator which is on the side of the convexity holds the pelvis posteriorly. A finger of the other hand is placed on the transverse process of the upper of the vertebrae involved, on the side of convexity. That finger gently holds the process in an anterosuperior direction as the patient steps forward on his elbows until tension is palpated with the finger. Then the patient moves forward the elbow on the side of convexity, lowering the shoulder on that side toward the table, as directed by the operator. The respiratory cooperation may be in either inhalation or exhalation. Lumbar Vertebrae Fig. 4. Thoracic Vertebra Convexity to the Left. The two inferior articular processes of each lumbar vertebra are cupped anteriorly and laterally between the superior articular processes of the vertebra below. All Rights Reserved American Academy of Osteopathy® 6 This pattern is usually present at the dorsolumbar and lumbosacral junctions. It per mits one or both facets of one vertebra to glide up and down in the trough made by the facets of the next lower vertebra. The arrangement of the joint surfaces and of the capsular ligaments is kept in mind as the corrective technique is applied. Fig. 6. Lumbar Correction Convexity to the left. The ilia are held posteriorly by the fingers. Fig. 5. Lumbar Palpation of motion as the hips axe elevated alternately. The patient is seated on the operator's knees or on a Ritter stool facing the table. The operator holds the patient's pelvis with his forearm anterior to the ilia and the patient moves his elbows alternate1 forward on the table. This increases the tension on the capsular ligaments and separates the spinous processes. Tilting the patient's pelvis laterally with the knees produces sidebending of the lumbar spine which can be localized by the palpating fir ger of the operator, placed on the spinous process of the vertebra in lesion. Flexion - The patient moves forward with his elbows until the increase of ligamentous tension is noted by the operator, the spinous process of the upper of the two vertebrae is held in a cranial direction to exaggerate the lesion position, and the patient then holds the breath in inhalation for correction. Extension In the extension lesion the pelvis is steadied, the ligaments are tensed as above, the operator holds the spinous process of the lower of the two vertebrae anterosuperiorly, and the patient moves back on his elbows to balance the tension in extension at the point of lesion. Then the respiratory cooperation is in the exhalation phase. Sidebending The sidebending lesion position is exaggerated to the proper extent by elevating the pelvis on the side of concavity. The arm of the operator on. the side of convexity holds the pelvis posteriorly as the patient steps forward with his elbows to tense the ligaments. The operator holds the spinous process of the lesioned vertebae toward the convexity and the patient comes back with his elbows until the finger on the spinous process notes a balancing of the ligamentous tension. Then the patient inhales and holds the breath for correction which usually occurs at the beginning of exhalation. Ribs The rib lesion is considered as an articular strain of the capsular, radiate and interarticular ligaments connecting the head of the rib to the bodies of the vertebrae. In the corrective technique the ligaments are tensed by using first degree leverage of the rib to lift its head anterc laterally from the facets on the vertebral bodies. The rib is shaped somewhat like a. horseshoe with a long arm from the angle to the anterior end and the short arm from the All Rights Reserved American Academy of Osteopathy® angle to the head of the rib. The costotransverse articulation acts as the fulcrum as the operator holds the shaft of the rib to prevent it from moving forward when the patient rotates the bodies of the vertebrae away from the head of the rib. The technique is usually applied with the patient seated and the operator on the side of lesion holding the rib. However it may be done with the patient lying on the back or on the side opposite the lesion. The patient is instructed to keep his head erect and not twist the neck as he turns the body slowly, carrying posteriorly the shoulder on the side opposite the lesion. In other words, the operator holds the 'bolt' while the patient turns the 'nut' to release the fixation. Sensing the point at which the ligaments are tensed but not unduly stretched, the operator instructs the patient to hold that position while he inhales and holds the breath for correction of the lesion. Diagnosis is made in the usual manner, considering history of trauma, pain and tenderness, tissue tensity and induration, possible abnormality of position, and restricted motion. If the first and the last two diagnostic points indicate a rotation of the rib in a particular direction, that position may be held in exaggeration for the correction, otherwise simple disengagement of the costocentral articulation alone is used. Fig. 7. Rib Technique thumb, of the hand which is toward the front of the patient, follows upward and backward from the axilla, close to the scapula, to contact the rib as near the angle as possible. The thumb maintains that contact while the patient gently lowers the shoulder, like slipping a glove down over the thumb, thereby causing a minimum of discomfort to the patient. A finger of the same hand holds the anterior end of the shaft and a finger of the other hand holds the posterior part of the rib near the point where it meets the transverse process. The thumb of this hand is placed at the inferior part of the lateral border of the scapula and holds that bone medially, posteriorly and upward away from the other thumb. The . patient's elbow is allowed to drop close to the body. Leaning toward the operator, the direction in which the rib held, rotation of the trunk and respiratory cooperation are similar to the technique described above. Fourth To Tenth For lesions of the fourth to tenth ribs, inclusive, the middle finger of one hand of the operator is on the angle and the middle finger of the other hand on the anterior end of the shaft of the rib, and the thumbs are placed laterally on the Firs Rib shaft.

First Rib Thumb under the trapazius. bedside is to have the patient seated with his hands or forearms resting on the shoulders of the operator who is seated facing him. The operator holds the sternal end of the rib posteriorly with the fingers while the patient rotates the body, carrying posteriorly the shoulder opposite the lesion. This disengages the head of the rib for car rection with respiratory cooperation. Fig. 10. Eleventh and Twelfth Ribs Middle finger acts as a fulcrum. while the patient rotates the trunk and holds the breath. Rib Lesions Associated with Hyperextension -of the - Vertebrae A distressing type of rib lesion is the one associated etiologically and pathologically with rather extreme extension of the spine. Produced during extension and perhaps sidebending with the convexity on the side of lesion, the head of the rib is caught in a depression between the bodies of the vertebrae caused by a separation of the demifacets while in that position. This interferes with flexion and bending toward the side of lesion, which motions are painful. The involvement may be bilateral due to the ribe being traumatically forced posteriorly or pulled by the pectoral muscles when the spine is hyperextended. Correction is made on one side at a time and it sometimes is difficult of accomplishment. With the patient lying on the side opposite the lesion and in partial flexion the operator stands in back of him. One Fig. 9.

The patient is seated and his shoulders are lifted by two assistants, one on each side with a hand under the axilla, the patient's elbows remaining at his sides, This tends to open a gap between the demifacets and release the head of the rib. The lift should be just sufficient to tense slightly the intervertebral ligaments and it is maintained while the operator proceeds with the respiratory technique for the rib involved. Pelvic Girdle The auricular surfaces of the sacrum and the ilium, covered by cartilage, lie more or less in sagittal planes, but flaring anteriorly and inferiorly. Their shape is that of a broad letter "L", the long arm being directed dorsoventrally and from its anterior end the short arm extends cranially. Roughly following the line of this "L" there is usually a curved ridge on the auricular surface of the ilium which fits into a groove on the sacrum. They describe an arc around a transverse line running approximately through the spinous process of the first or second sacral segment. The arrangement of the ligaments is such that the sacrum can swing within limits between the ilia along the line of those ridges without materially changing the tension. Meanwhile the ligaments are limiting the tilt of the sacrum, downward and forward at the base and backward and upward at the apex, caused by the weight of the trunk through the lumbar spine when in the erect position. There is a notable absence of muscles between the sacrum and ilia which would control the motion of one upon the other. Doctor Sutherland has called attention to an involuntary movement of the sacrum between the ilia in contradistinction to the postural mobility of the ilia upon the sacrum. This involuntary motion is associated with what is termed in his cranial concept as the 'primary resiratory mechanism' which concerns a motility of the neural axis. The dural membranes, the cerebrospinal fluid and the cranial bones and sacrum participate in the movement. The primary respiratory mechanism is fundamental to the pulmonary respiratory, the cardiovascular and the various other systems of the body, so is not to be confused with diaphragmatic breathing. In the involuntary movement of the sacrum its base alternately moves cranialward and recedes downward as a part of the primary respiratory mechanism. The inhalation or flexion phase of the movement causes the base to draw upward and the apex to move anteriorly, the sacrum swinging on the arc of the L shaped auricular surface or the ridge and groove described above. Since this movement reduces the anterior convexity of the lumbosacral junction and since it bears no relationship to the movement of the sacrum as the trunk bends forward in the standing position, the term respiratory flexion is applied to it. "Respiratory extension' of the sacrum takes place when the base is lowered, the lumbosacral convexity is increased, the sacrum swings posteriorly in its arc and the apex moves posteriorly. Postural or voluntary movement of the ilium upon the sacrum is familiar as the rotation of the innominate bone anteriorly or posteriorly on a transverse axis through the body of the second sacral segment. Respiratory Lesions of - the- Sacrum Diagnosis of sacral 'respiratory) lesions is made with the patient in any position, usually seated.' The thumbs or fingers of the operator bridge from the posterior superior spanes of the ilia to the dorsum of the sacrum near the base or from the posterior inferior spines to the contiguous part of the sacrum. The respiratory motion is accentuated by having the patient breathe All Rights Reserved American Academy of Osteopathy® 10 deeply, and the freedom or limitation in ward from between the ilia. When the disthe movement of the sacrum in its arc is engagement is palpated the patient is inpalpated.

Respiratory Extension The patient's knees should be together and For "respiratory extension" lesions feet forward. The operator stabilizes the the operator holds the base of the sacrum pelvis with a forearm against the anterior forward and downward on the side of lesion superior spines and the patient bends forward to walk on the table with his elbows with his finger, and the apex posteriorly or hands of necessary, away from his pelvic with his thumb under one side of the apex. The forearm on the side of lesion holds the bones. This draws the sacrum anteriorly, tending to disengage it from its wedged po- pelvis posteriorly while the patient steps forward on the table with his elbows or sition between the ilia, causing it to be hands. The proper point of balanced tension virtually suspended. It also releases the tension of the iliopsoas muscle. Respiratory Flexion If the lesion be of the "respiratory flexion" type with the sacral base drawn up. ward and slightly posterior and the apex forward, the operator steadies the pelvis with the forearm on the side of lesion, avoiding a posterior pull upon it. The thumb of the other hand holds the apex forward, swinging the base upward and posteriorly for exaggeration of the lesion position. The patient then steps forward with Fig. 13. Respiratory Extension Lesion of the Sacrum depends upon the amount of pull as the patient's shoulders move forward, the degree to which the lesion position is exaggerated by the operator's thumb and finger, and the relative position of the ischial tuberosities as they are moved by the operator's knees. Correction occurs with the patient holding his breath out as long as possible. Bilateral Bilateral flexion or extension lesions of the sacrum may be reduced with one procedure or on one side at a time. If the his elbows or hands on the table drawing the sacrum be rotated so that the ligamentous imbalance is toward flexion on one side and sacrum forward and, because of the flexed position of the lumbar spine, slightly down- extension on the other it is simpler to Fig. 12. Respiratory Flexion Lesion of the Sacrum All Rights Reserved American Academy of Osteopathy® 11 correct each side separately. Postural Lesions Postural sacroiliac or iliosacral lesions are diagnosed with the patient seated on the operator's knees. The tuberischii are alternately elevated and the motion between the sacrum and the posterior the position of correction. (This is "direct action" technique, so if it is an anterior rotation lesion the bone is held in posterior rotation, and vice versa.) The patient then flexes the knee which Fig. 14. Postural Sacroiliac, Diagnosis superior iliac spines is palpated. If the motion is free as the tuberosity is elevated and moved posteriorly and limited when moved the opposite direction, the ligamentOUS articular strain denotes anterior rotation of the innominate bone. Restricted motion when the tuberosity is moved backward and upward indicates a posterior rotation lesion. The diagnosis may be made with the patient seated on a Ritter stool, lowering the pelvis on one side or the other. The diagnostic motion or its limitation is elicited as the patient abducts the knees alternately. Correction of the postural lesions IS made with the patient standing, his hands on a stool which is placed on the table. The leg on the side of lesion is crossed in front of the other one and the foot rests on its outer edge, lateral to the one on which he stands. In this position the weight is transmitted from the spine through the sacrum to the innominate bone which is not directly concerned in the technique. The sacrum is thus stabilized and the lesioned innominate is left suspended. The operator, sitting at the side of the patient, holds the tuberischium in the palm of one hand and the crest of the ilium in the other. The innominate bone is rotated with the hands, anteriorly or posteriorly toward Fig. 15. Correction of Anterior Rotation of the Innominate Operator rotates the ilium posteriorly on the sacrum. bears his weight to about 135 degrees, keeping the other leg relaxed, and returns to the erect position while the operator maintains the rotation of the innominate in the direction of correction. Pubic Symphysis The symphysis pubis is subject to ligamentous strain, frequently in association with sacroiliac 1esions. There is an intervening cartilage between the pubes denoting motion. The bones are bound together by strong ligaments, some of whose fibres are diagonally placed making them especially susceptible to strain or imbalante. An unevenness of the superior borders of the pubic bones may be palpated. The inferior ligament, extending between the inferior rami, is pierced by the urogenital All Rights Reserved American Academy of Osteopathy® table are placed between the inferior rami near the symphysis with a finger of the other hand between the proximal phalanges to act as a fulcrum or wedge to spread the tips of the fingers apart. This tenses the interpubic ligaments and the tension may be balanced by advancing one or the other- finger anterosuperiorly. The patient cooperates by pressing his knees together. A thick pillow between the knees is helpful. In the female patient the thumb of one hand and fingers of the other are used to spread the symphysis. Upper Extremity Clavicle The object of the technique for correction of lesions of the clavicle is to hold it cranialward and laterally while the patient lowers his shoulders and rotates the trunk, dlsengaging the sternal, costal, coracoid and acromial articulations to tense their ligaments. The patient sits on the table and the operator sits facing him, Fig. 16. Correction of Posterior Rotation ducts and by a branch of the internal pudic nerve in close proximity to the symphysis, which is an indication of some of the symptoms that may be present. A spreading or disengagement of the articulation is accomplished with the patient lying on the side with his thighs flexed. The operator stands in back of him The tips of the index and middle fingers of the hand which is toward the foot of the Fig. 18. Clavicle Fig. 17. Pubic Spread a thumb under each extremity of the clavicle. The fingers of one hand rest over the acromioclavicular junction for the purpose of palpatlon and a finger of the other hand is placed medial to the sternal end of the clavicle to hold it laterally. The patient, with his arm on the involved side lateral to the operator's arm, rests his hand on the latter's shoulder. The patient drops his weight forward on the thumbs of the operator, who balances the ligamentous tension at the acromial end of the clavicle by All Rights Reserved American Academy of Osteopathy® carrying his shoulder and the hand resting on it backward away from the patient. Under direction the patient draws his opposite shoulder posteriorly to move the sternum away from the clavicle and tense the ligaments at that articulation. The clavicle is balanced over the costoclavicular ligament and the patient inhales and holds the breath for correction. Humerus Freedom of rotation of the humerus in the glenoid cavity is tested with the arm at an angle of 45 to 90 degrees laterally from the body, and the elbow flexed. Fig. 19. Testing External Rotation of the Humerus Comparison of the motion on the two sides is made by carrying the hand laterally and upward to test external rotation of the humerus and medially and downward for internal rotation. Restricted motion in one di- Fig. 20. Testing Internal Rotation of the Humerus 13 rection indicates lesion in the opposite position. Correction is made with the patient seated, the operator standing on the side of lesion, facing him and with the hand which is toward the back of the patient palpating the shoulder joint. The other hand under the axilla, against the ribs and as close to the head of the humerus as possible, acts as a fulcrum for disengagement. The patient places the hand of the involved side over the distal third of the opposite clavicle and holds that shoulder. The internal rotation lesion is exaggerated by the patient elevating the elbow, external Fig. 21. Corrective Technique, External Rotation of the Humerus rotation by lowering it, the operator directing to the degree necessary to arrive at the point of balanced tension. The patient is instructed to move his uninvolved shoulder posteriorly, carrying with it the Fig. 22. Corrective Technique, Internal Rotation of the Humerus All Rights Reserved American Academy of Osteopathy® 14 hand of the lesioned side. This draws the I lower end of the humerus across the chest in order that the leverage over the fulcrum provided by the operator's hand disengages the head of the humerus. Respiratory cooperation is then employed to correct the lesion. Forearm, Wrist and Hand The bones of the forearm move in relation to each other on a double swivel. The proximal head of the radius rotates in the annular ligament and the distal head around the end of the ulna. Little motion is possible between the humerus and ulna except flexion and extension. The capsular ligament of the elbow is composed of interlaced and confluent fibers that operate as a unit and unbalanced tension may be caused by strain of the elbow joint or result from rotation lesions of the humerus. Strains which disturb the position of the olecranon process prevent complete extension of the arm and those which affect the coronoid process prevent complete flexion. The semilunar notch between these two processes, which receives the trochlea of the humerus, opens anteriorly at about a right angle to the shaft of the ulna but is frequently at an angle of more nearly 135 degrees. Ulna The corrective technique for ulnar lesions is applied with the patient seated facing the table, elbow flexed to about 90 degrees and his hand, palm down, on the table. The fingers are spread as widely as possible to release the metacarpals and the distal row and possibly all of the carpal bones. The operator sits on the side of lesion and rests his fingers over the dorsun of the carpus and proximal ends of the metacarpals and the thumb on the styloid process of the ulna for palpation. The fingers of the other hand grasp the olecranon process. The patient inverts and everts the humerus, raising and lowering the elbow, while the operator finds the direction in which the motion is limited and determines the point of balanced ligamentous tension. The operator then holds the proximal end of the ulna away from the humerus by means of the olecranon process, or the patient may steady the wrist with his other hand while the operator holds both the olecranon and coronoid processes, tending toward rotation of the ulna to the proper degree. The patient then Fig. 23. ulna raises his shoulder to draw the humerus out of the semilunar notch of the ulna for release and correction. The direction of the pull on the humerus may need to be at an angle greater than 90 degrees to prevent binding on the olecranon process, the operator's sense of touch deciding that point. Radius Lesions of the head of the radius prevent free supination or pronation of the forearm. For correction the position is similar to that for ulnar lesions, except that the patient's elbow is only slightly flexed. The operator holds both ends of the radius with his fingers, palpating for the ligamentous imbalance as the patient circumducts his elbow upward or downward and medially to rotate the humerus in relation to the radius. When the point of balanced tension is found the radius is held firmly by the operator for stabilization, Fig. 24. Radius All Rights Reserved American Academy of Osteopathy® 15 and the 'patient circumducts the elbow a little farther for exaggeration and correction. Wrist and Hand In dealing with lesions of the wrist and hand it is well to remember the intercommunicating artlcular cavity of the joints and the dorsal convexity of the arch formed by the wedge shaped proximal heads of the metacarpal bones, narrowed on their volar aspect. The patient sits with his hand on the table, palm down and fingers spread. Facing him, the operator holds downward the dorsum of the distal end of the metacarpal with his thumb, and he lifts and separates the proximal heads of that and the metacarpal on either side of it with the ball of his middle finger, placed under the palm between the proximal ends of the shafts of the bone being held by the thumb and of the one on either side. When Fig. 26. Hand Dr. A. T. Still used his flexor profundus digitorum muscles in correcting lesions of the wrist and hand. He interlaced his fingers with the patient's wrist between his palms. The patient spread and extended his fingers, making the back of the hand as nearly concave as possible. Varying the pressure by means of the flexor profundus digitorum muscles Dr. Still found the point of balance at the exact location of the lesion and allowed the bones to spring back into normal relationship as the patient relaxed his hand. Fig. 23. Wrist the metacarpals are lifted dorsally and separated they are also rolled on their long axes. The operator's other hand on the dor sum of the wrist stabilizes the carpal bones. With this procedure the restriction is found and the ligamentous tension is brought into balance and held. Then the pa tient spreads his fingers more widely to disengage the lesioned- articulation for cor rection. Lesions of the carpal as well as the metacarpal bones may be reduced by this technique. The procedure is completed by the operator holding and rotating on their long axes the involved fingers, one at a time, while the patient, keeping his fingers widely spread, slowly withdraws his hand, raising and lowering his elbow. Fig. 27. A.T. Still's Wrist Technique Lower Extremity Hip Joint The capsular ligament of the hip joint is strong, comparatively lax, permits a wide range of motion and is frequently subjected to strain. Diagnosis of lesions of this articulation is made with the All Rights Reserved American Academy of Osteopathy® 16 Fig. 28. Testing External Rotation of the Femur patient standing, the weight on one foot. Without turning the pelvis he rotates the leg that is not bearing his weight, pointing the foot laterally and medially to determine the degree of external and internal rotation of the head of the femur in the acetabulum. Comparison of the motion in either direction on the right and left side: designates the lesion., In another method of diagnosis the patient is seated on the table with one leg resting over the other knee. The operator, facing him, holds the leg at the knee and ankle and rotates' the femur in question by tilting the leg in either direction over the knee on which it rests. Restrictions caused by exostosis or other bony abnormalities are usually indicated by a less resilient limit of motion than is present in ligamentous articular strains. For the corrective technique, the patient sits across the table with the uninvolved hip next to the end. The leg of the lesioned side is crossed over the other knee, resting midway of the shaft of the fibula. The operator sits at the end of the Fig. 29. Testing Internal Rotation of the Femur table, one hand medial to the shaft of the involved femur near its head, holding it laterally. The other hand reaches around in back of the pelvis to palpate the motion at the greater trochanter. In the case of an external rotation lesion, the patient holds his knee laterally and downward with his hand for exaggeration, sidebends and rotates his body Fig. 30. Testing External Rotation of the Femur All Rights Reserved American Academy of Osteopathy® Fig. 31. Testing Internal Rotation of the Femur away from the lesioned side and leans backward. The operator firmly maintains his fulcrum against the shaft of the femur and determines the point of ligamentous balance The correction occurs with exaggeration of the lesion position and disengagement of the articulation. Fig. 32. Corrective Technique, External Rotation of the Femur, variation from the text. Internal rotation lesions are corrected with the operator holding the fulcru on the femur more proximally than in the former technique and palpating for ligamentous balance with the other hand at the greater trochanter as above. The patient draws his knee medially and upward with his hand, leans forward and sidebends and rotates the body toward the side of lesion for, exaggeration to the proper degree. Dr. A. T. Still used a similar .tech- Fig. 33. Corrective Technique, Internal Rotation of the Femur, Variation. nique in which he sat on the patient's uninvolved thigh and the leg on the side of lesion was crossed over Dr. Still's knee. The principle of exaggeration and fulcrum disengagement was used for correction. Tibiofemoral Tibiofemoral lesions, sometimes referred to as dislocated semilunar cartilage, are caused by a sudden or forcible ro_ tation of the tibia in relation to the femur, usually in conjunction with a sidebending strain upon the knee. In a majority of instances the medial condyle of the tibia has been rotated anteriorly when the foot was turned laterally and the knee bent medially, the lateral articulation of the knee joint having acted as a fulcrum. History of the injury, location of the tenderness, inability to fully extend the knee in most cases, pain and restriction on attempting to reverse the lesion position, and palpation establish the diagnosis. For correction the patient is seated with the involved leg balanced over the opposite knee. Facing him, the operator places one hand on the knee and grasps the foot, just below the ankle, with the other hand. If the lesion be of the medial condyles the operator provides a fulcrum on the lateral condyle of the tibia with his thumb, one or two fingers are on the medial condyle of the femur for palpation, the knee is carried medially and upward, tipping the foot laterally and downward, to disengage the lesioned joint surfaces and tense the ligaments. The tibia is rotated externally or internally by the other hand at the All Rights Reserved American Academy of Osteopathy® Fig. 34. Tibiofemoral Fig. 35.

Tenderness, disturbances of the ankle joint and circulation of the foot, and limited motion of the fibula in relation to the tibia give evidence of the lesion. For correction the patient sits with his leg, near the ankle, over the other knee. The operator holds both ends of the fibula anteriorly with his fingers to the point of balanced tension of the ligaments. The patient dorsiflexes and externally rotates the foot and presses downward on the knee or lifts it upward and medially with his hand. This rotates the fibula and releases it at both ends from the tibia and from the astragalus. Further disengagement and Fig. 36. Tarsal Arch All Rights Reserved American Academy of Osteopathy® 19 structure of the foot are corrected by a method contrived by Dr. Sutherland based on the beneficial effects of removing a tight boot by means of the old fashioned bootjack Each time the device was used the user gave himself a foot treatment. Characteristic of the fallen arch are the anterior position of the astragalus between the malleoli and in relation to the calcaneus, and the lowering of the calcaneu: anteriorly, of the medial part of the cuboid, and ofthe longitudinal and transverse arches. The technique, like the operation of pulling the foot out of the boot, lifts and moves the structures back into their normal relationship. In preparation for the corrective technique the patient or the operator holds the tuberosity of the calcaneus and the metatarsals medially with the fingers. The thumbs on the inner side of the foot at the junctions of the calcaneus with the talus and the navicular with the internal cuneiform lifts those structures laterally and hand grasp the posterior part of the Calcaneus and hold it medially and downward while the thumb lifts laterally and upward on the inferomedial aspect of the cuboid. The operator rotates the anterior part of the foot internally and externally to balance the ligamentous and fascial tension and continues to hold medially and downward on the tuberosity of the calcaneus while the patient draws on the achilles tendon for exaggeration and correction. Fig. 38. Tibio-Calcaneo-Astragalus Fig. 37. Preparatory to "Bootjack" Technique upward, bending and stretching the foot around the thumbs. Following that procedure the patient drops the foot and ankle into plantar flexion and the operator place between two of the toes the web of the thumb of the hand that is toward the latera side of the foot. The thumb holds the dorsum of the distal heads of the metatarsals downward and the middle finger of that hand under the shafts of the metatarsals rolls them on their long axes and lifts and separates the proximal heads, which are wedgeshaped and narrowed inferiorly. This releases the metatarsal and the distal row of the tarsal bones. The fingers of the other Astragalus, Calcaneus, Tarsal Arch Another useful procedure in the release and correction of tarsal lesions, especially the astragalus, makes use of the fact that strong dorsiflexion of the foot elevates the arch. The operator interlaces his fingers in back of the' heel and with his palms holds the astragalus and calcaneus firmly in the position they would take in extension of the ankle joint. The patient dorsiflexes and inverts and everts the fore part of the foot against the resistance provided by the operator. Non-Osseous Structures Soft tissue treatment in osteopathy has been frowned upon since the early days when Dr. A. T. Still referred to some types of it aslengine wiping'. It has been associated in the minds of many of us with rubbing or massage, yet intelligent and scientific adjustment of non-osseous structures is as truly osteopathic as correction of bony lesions. Dr. Still regarded the body as a complex unit composed of interrelated parts working in harmony, each endowed with the All Rights Reserved American Academy of Osteopathy® 20 inherent desire, intelligence and ability to perform its function according to the plan of a Master Mechanic. When circumstances prevent any part of the body, whether bony or soft tissue, from doing so, the effects are far reaching. Perfect health ensues when each part is in perfect adjustment and free to do its work. Dr. Still had the greatest respect for the humours and the fasciae, the nerves, vessels, viscera and all the other elements that compose the body. He had a remarkable faculty of being able to locate maladjusted tissue, of associating cause with effect, and tracing effects back to cause. That quality is reflected in Dr. Sutherland's technique. The fasciae envelop, separate, protect and support the various structures. Not the least important of their functions is to encourage and direct the movement of tissue fluids and to promote the flow of lymph through its channels. The various layers of fascia interconnect and present a continuity from head to foot. Dr. Still recognized 'drags' on the fasciae which are caused by hypotonicity, the weight of viscera, strains, and posture. Treatment to restore the normal tension, hence function, of the fascial system is extremely effective. the table or side of the bed facing the operator. His body is flexed and head hangs forward. The operator directs his thumbs posteriorly and downward over the clavicle just lateral to the attachment of the sternomastoid muscles. With the arms lateral Fig. 39. Cervical Fascia, First Position to those of the operator the patient rests his hands on the shoulders of the operator and slowly drops his weight forward. This advances the thumbs down into the mediastinum just anterior and to either side of the trachea. The operator approximates his thumbs enough to gently hold the pretrachea fascia while the patient slowly assumes the erect posture, but with the neck remaining Anterior Cervical Fascia in flexion. It is unnecessary to go so The anterior cervical fascia is atdeep into the mediastinum as to be uncomtached to the base of the skull, the mandible, hyoid, scapula, clavicle and sternum. fortable to the patient. This technique Through the pretracheal it is connected with lifts the fascia and reduces the 'drag' from below. the fibrous pericardium, and thence with the diaphragm. It surrounds the pharynx, larynx and thyroid gland, it forms the carotid sheath, and by way of the prevertebral fascia is connected with that which surrounds the trachea and esophagus. Therefore, the cervical fascia is concerned quite directly with lymphatic drainage of the head, neck, thorax and upper extremities. Not only voluntary movements, but,respiratory activity is a factor in this vital function of the fascia, moving it forward in exhalation and backward in approximation to the spine during inhalation. Restoration of free movement of the deep cervical fascia renders unnecessary much of the soft tissue treatment of the neck and helps in overcoming intrathoracic congestions. The 'drag' on the cervical fascia is eliminated by having the patient seated on All Rights Reserved American Academy of Osteopathy® 21 Diaphragm Because of its relationships the diaphragm deserves consideration other than as a muscle of respiration. The pericardium is firmly attached to it above, the peritoneum below, and the great vessels and esophagus pass through it. Being rather closely associated with the organs of respiration, circulation and digestion, it is important that the full excursion of the diaphragm be unimpeded. This is prevented by a 'drag' on the abdominal fascia and may be restored by a technique known as the diaphragmatic lift. The object of the treatment is to draw the diaphragm cranially, eievating the floor of the thorax, drawing upward on the abdominal contents and promoting venous and lymphatic drainage from the lower half of the body. Visceroptosis and even internal hemorrhoids respond to it tension affecting the important structures passing through the arches of the diaphragm is relieved. The patient seated, the operator facing him from the front or at his side starts his thumb under the twelfth rib just lateral to the erector spinae mass. The right thumb is used for the left side of the patient and vice versa. The patient Fig. 42. Arcuate Ligaments bends his trunk over the operator's thumb which gently and gradually advances upward and posteriorly as the patient exhales, and holds its position as he inhales. When the thumb arrives at a point against or under the ligament it is drawn laterally with a rolling motion which relaxes the external and often influences the internal arcuate ligament.

After several respiratory cycles there is no further upward progress and the patient is told to breathe out, close the throat and attempt to expand the chest.

The false ribs may be treated similarly, Dr. Sutherland reporting the passage of gall stones without pain when the tenth rib on the left was held in that manner. The effects are produced by way of the sympathetic chain lying in close proximity to the heads of the ribs. -Psoas Muscle Contractures of the psoas muscles exist in varying degrees, from acute spasm Fig. 44.

If the patient is bedfast he lies on his side with a pillow under the shoulder to produce the sidebending, the rest of the technique following the principles of that described above. When the treatment is given for its influence upon the cecum, a chronic appendix, colon, small intestine, kidney or ureter, the psoas is held forward while the patient rotates his thigh alternately internally and externally. In the bedside technique this is done with the patient more or less in the Sim's position, lifting the knee laterally and lowering it to the bed. Iliopsoas Tendon The iliopsoas tendon may be lifted or stretched by holding it forward at a point just proximal to the lesser trochanter, the patient lying on the back. This treatment relieves the anterior tension upon the spine in lordosis, gives relief in the passage of renal calculi and is an effective measure for sciatica. An effective technique for reducing the 'drag' on the fasciae is applied with the patient lying on the left side. His thighs are straight or slightly flexed to Fig. 45.

Popliteal Drainage slightly flexed and he alternately presses against the table with the heel and relaxes. The effort to flex the knee tends to compress the tissues of the popliteal space, and it expands when the patient relaxes the leg and the operator separates the tendons. The effect is that of a boost er pump in the return of the fluids toward the heart. The osteopathic articular lesion, being primarily an unbalanced tension of the ligaments with strain as the usual cause, is corrected mainly through the agency of the ligaments themselves. The natural tendency of the body is to revert to normal when the balance is restored and the factors preventing the return are removed. It will be noted that as a rule gliding separation of the joint surfaces is used to tense the ligaments in vertebral, sacroiliac, carpal and tarsal lesions. Fulcrum leverage for disengagement is employed in lesions of the long bones, combined with exaggeration of the lesion position in those of the extremities. The principle of the fascial treatment is to lift the fascia at its more dependent part, the patient cooperating. Dr. Sutherland's technique seems a radical departure to most of us. It avoids the familiar thrusting and popping of joints. However, it is based upon the fundamental principles of osteopathy as conceived by Dr. Still and accords with his admonition that osteopathic technique should be gentle, easy and scientific.

Although the latter part was hurried because of lack of time, such an outline was followed when I taught technic in Kirkville last February and I believe it was a successful presentation,. judging from the continued interest and correspondence I am still receiving from a considerable number of the students. It gets away from the thing that has made technic teaching so mediocre for years, by emphasizing "fundamentals" and "fine distinctions" and making the actual demonstrations and practice incidental. I believe it is essentially the way we must follow to secure the superior results we so earnestly desire from this teaching program. 25 All Rights Reserved American Academy of Osteopathy® 26 The teaching of practice, the treatment of specific diseases, is of secondary importance to the learning of actual principles of technic. However it should be included as much as possible in the course to give the wealth of experience of such men as Wilson, Sisson, Fryette and others, to the students. If time is limited, the cut should be in practice, not in technic, because the physician is nothing without technic and if he is bright, he will, with sound osteopathic theory and a good technical foundation, develop a good treatment for a disease even if not specifically instrutted how to treat it. principles upon which Osteopathy is founded." "They cannot demonstrate to you how to use it. If you want to be an imitator, study in a bath house."

Then he may apply his anatomical and physiological knowledge to do specific manipulations or other therapeutic measures which change the body so that disease becomes less compatible with it. Only those specific measures arrived at by this process of diagnosis and reasoning are indicated. All others are contraindicated. They may be harmful. The "Let's try this and see what happens" school of thought, is a dangerous one. Technic teachers and students must keep this concept in mind in order that the student understands the methods taught. And finally, a word should be said directly to the persons who are concerned in this process of exchanging ideas. The concert master is not always the best teacher. The successful physician may not be able to impart his knowledge and ability until he learns how to teach. On the other hand many who may not be so proficient may be able to teach successfully. Each of those who have some knowledge of the philosophy of osteopathy and the technic of its application to human ills, should contribute to the best of his ability that much to the contemporary stream of knowledge. That particular contribution may be the means of helping someone strengthen some weak link in his osteopathic technics, it may be the thing many thinking physicians are seeking. And, if it is worth presenting for study, It is worth presenting well and studying thoughtfully. The teacher should do his best. The student is under obligation to do likewise. There must be tolerance and understanding on both sides of the teacher's desk to make the process most valuable. Diagnosis of Pathology in Relation to the Osteopathic Lesion. It is practically impossible to define an osteopathic lesion so that what a lesion is and what it is not, are unequivotally stated. Yet the important characteristics of the lesion are well known and can be demonstrated. In spite of lack of proof from the research scientist, certain groups of physical findings can be said to constitute a lesion. The detection of these physical conditions are the evidence from which a diagnosis of the lesion can be made. The interpretation of these findings according to osteopathic principles as they affect the body economy, is osteopathic diagnosis. For our purpose, let us define an osteopathic lesion as a change in structure which alters function.* This definition is based on the osteopathic tenet that normal function depends on normal structure and the law taught in biology that structure determines function. Therefore, a change from normal structure may produce and maintain abnormal function, and a return to normal structure permits function to normalize if the process still is reversible. The physical findings of a lesion are the evidence of certain changes which have taken place within the body, and their discovery constitutes a recognition of existing pathology and/or displaced structure. The problem in diagnosis is, first, to recognize such changes and second, to interpret them, preparatory to treatment. An understanding of the pathology of the lesion is prerequisite to intelligent diagnosis. A brief review of this pathology and a correlation of it with physical findings enables one to present his technic of diagnosis in a manner easily grasped. According to Louisa Burns, the pathology of the osteopathic lesion is basically, as would be expected, that of inflammation. The detection of the stage of inflammation, and as treatment is administered, the resulting changes are the object * This broad definition is not the usual one given since when an osteopathic lesion is mentioned, an articular lesion is commonly meant. The official definition sanctioned as Standard Osteopathic Nomenclature for Osteopathic Technic (P 242 J. A. O. A. January 1936) is: "An osteopathic articular lesion is any alteration In the anatomical or physiological relationships of the articular structures resulting in local or remote functional disturbance." All Rights Reserved American Academy of Osteopathy® of diagnostic search. The ability to discover abnormal tissues is one of the most difficult arts to master. Educated touch coordinated with an intelligent, alert, inquiring consciousness, will find much information overlooked by the novice, as well as by the careless or hurried technician. Unfortunately, the finer distinctions are never sensed and appreciated in many practices. The development of diagnostic ability requires concentration and application to detail and constant study in correlating osteopathic theory with detailed findings. For descriptive purposes, the traumatic spinal lesion may be chosen as a typical osteopathic articular lesion. The following discussion relates to such a lesion*, other lesions may also be understood by the application of reason. The student should study this from Burns' new book. The first detectable change after the production of an osteopathic spinal lesion and preceding the onset of inflammatory changes, is the shock reaction. The chief characteristic of this reaction is a decreased tonicity of periarticular tissue, amounting to flaccidity in some cases. Muscles are relaxed and mobility of the joints in the area is increased. However, careful testing will show that usually motion is slightly less in one direction than in others, indicating the presence of a lesion. There is a reflex change in circulation, locally and in related segments, due to narrowing of arterioles after the shock, followed by an increased permeability of the capillaries and a beginning of edema,** which gradually increases. The detection of shock reaction is difficult. Increased mobility makes the limitation of motion on one or more directions appear to be normal because the relatively limited motion may still be as great as normal motion. Tissue relaxation may be overlooked by fingers feeling only for increased tensions and for the changes characteristic of inflammation. Alteration of relative position is often not detectable because contraction of longer muscles 29 (white muscle), due to inflammation is not yet active in producing deformity. The chief diagnostic point noted in the stage of shock is an alteration of tissue feel detected by very light palpation. The pads of the fingers, scarcely touching the skin, are stroked lightly across the area parallel to the long axes of the muscles. The skin presents to the slowly moving fingers a slightly cooler feel and a decreased drag, as compared to normal temperature and drag. This leads the diagnostician to investigate the area more carefully for the flaccidity and altered mobility characteristic of the lesion in the stage of' shock. Because the phase of shock is fleeting, lasting only from a few moments to an hour, it is seldom seen by the physician except as the result of trauma administered by himself in indiscriminating treatment. Many unexpected results following treatment may be explained by the local, or segmental, and systemic effects of shock reactions. On subsequent examination, the physician may be surprised by the presence of an aggravated lesion where he thought he had made an excellent correction. True, shock reaction may at times be of value, as in the control of nosebleed by shocking the upper cervical segments, but an accurate osteopathic diagnosis is necessary to guide the physician's hand if shock is to be used therapeutically. When produced accidentally, it should be recognized and appropriately treated. Subjectively, in shock, the patient may point out the lesioned area as one in which a sudden twinge was felt, possibly accompanied by a "click" or "pop". There is little or no pain on motion. In fact, if the area was previously painful or tight, the patient may say he now feels fine. However, after the lesioned person has cooled off following injury, he will complain of the onset of symptoms that result from the development of acute inflammation. In the second stage of traumatic lesion pathology, that of acute reaction * Dr. Burns' new book has this step by step. **C. H. Kauffnan attributes the edema to disturbed tensions due to changed anatomical relationship. The edema accumulating because the tensions prevent normal drainage may act as an irritant causing fibrosis without passing through the acute inflammtory stage in some reflex and compensatory contra&urea.

If one feels he mUSt vary from standard nomenclature he should be sure his hearers know the deviation and are reminded each time it is used. Definitions do not always convey the full implication of the term as used, so following several definitions a brief description will be given of the major findings discovered on examination of the parts under observation. These descriptions will apply only to the spinal organ, since generalizations including appendicular, sacral and cranial joints are impossible and since each extraspinal articulation must be considered separately. Both to teach and to learn technic accurately, these definitions and the statements of the physiological motions of the spine must be clearly understood and remembered. Flexion of the spine Is the position assumed by the vertebrae in physiological forward bending from the hips. This increases the anteroposterior curve in the thoracic and decreases it in the lumbar and cervical areas. The upper facets of the articulations move cephalad in relation to their opposing facets causing ligamentous and muscular tensions which impose certain limitations (to be discussed later) on free movement of the parts. Lesions (1) in this position exhibit certain characteristic physical findiws, whatever the pathological state of the tissues may happen to be. The spinous process of the lesioned vertebra is prominent and the interval between it and the one below is increased. It appears to be posterior and an indiscriminating examiner may call it a posterior lesion. If the whole area is placed in flexion the lesionec vertebra becomes Indistinguishable by obser vation from unlesioned vertebrae in this respect. Tension and tenderness are present in the interspinous tissues. Both articulations are moved equally creating similar tension and tenderness in affected ligamentc and muscles on both sides. This tension limits motion in the direction of extension while motion is permitted freely into increased flexion. This tension existing in marked flexion prevents lateroflexion unless it is preceded by rotation. Rotation is free If followed and accompanied by lateroflexion. Extension of, the spine Is the position assumed by the vertebrae in physiological backward bending from the hips. This increases the anteroposterior curve in the lumbar and cervical areas while the curve is decreased in the thoracic area. The upper facets of the articulations move caudad in relation to their opposing facets causing ligamentous and muscular tensions which impose certain limitations on free movement of the parts. Lesions in this position exhibit certain characteristic physical findings, whatever the pathological state of the tissues may happen to be. The spinous process of the lesioned vertebra Is depressed and approximated to the one below. It appears to be anterior and may be mistaken for an anterior lesion by a careless examiner. If the whole area is placed in extension the lesioned vertebra becomes indistinguishable by observation from unlesioned vertebrae in this respect. Tension and tenderness are equally present in affected deep ligaments and muscles on both sides of the spine. This tension limits motion In the direction of flexion but motion is permitted freely into increased extension. The tension produced in extension prevents lateroflexlon unless it is preceded by rotation. Rotation is free if followed by and accompanied by lateroflexion. Extension or flexion lesions uncomplicated by rotation and lateroflexion are rare but possible. There is no term officially recognized to describe the normal position of the spinal segments when there is perfect balance and neither extension or flexlon exists. The terms "neutral" or "easy normal" are used by some. The former seems preferable. Rotation is movement of a vertebra around a vertical axis. It is always accompanied by lateroflexion. In flexion and extension rotation always precedes lateroflexion while in neutral lateroflexlon (1) Osteopathic Lesion--herein used to mean anatomical and physiological changes in the spinal organs resulting in histopathological changes and functional disturbances. In disturbed intevertebral relationships the upper or more cephalad of the two is commonly considered to be the one in lesion although the lower may be thought of as in lesion if it is desirable.

All Rights Reserved American Academy of Osteopathy® 36 views should be included here. For this purpose I quote from the article "Dr. Fryette's Spinal Technic" in the 1948 Year Book of the Academy of Applied Osteopathy. (Quote) Corrective treatment of spinal lesions to be most effective and least damaging to the tissues must be physiologic, following certain definite movements determined by the mechanics of the spine. The physiological movements of the spine, two in number, according to Fryette, may be stated thus: (1) "If any area of the spine be in physiological extension or in extreme flexion so that the facets are locked, it is necessary to rotate toward the side to which sidebending is desired before sidebending can take place. This operation occurs naturally in the sequence of extension or extreme flexion, rotation and sidebending." (2) "If any area of the spine be in neutral and sidebent, the body of the vertebra rotates to the convexity of the curve so formed. Thus we have in sequence neutral, sidebending and rotation." The term sidebending Is preferred by Fryette as being less cumbersome and confusing than that of lateroflexion. The term neutral, is preferred to easy flexion or easy normal, as used by some, to indicate that condition of the spine In which the facets have not been locked in any degree of extension or in extreme flexion. "It has always seemed strange to me that so many of our profession, even the committee of nomenclature, Insist that flexion and extension of the trunk on the thighs is analogous to flexion and extension of the spine. As a matter of fact, it has no more to do with flexlon and extension of the three anteroposterior curves of the normal spine than have flexion and extension of the arm or foot." "When speaking of the cervical region, for instance, one is quite obviously not speaking of the entire spine and it is inaccurate to speak of backward bending of the cervical region as extension of the cervital curve. The same is true of the lumbar area. It just happens that flexion of the trunk on the thighs results in flexion of the thoracic curve and that backward bending of the trunk on the thighs results in extension of the thoracic curve. This is not true of the cervical and lumbar curves. They may say, "What's the difference?" Just this: Let us divide spine up into its three anatomical parts and see how each functions. First, take the lumbar, with its anterior curve and put It in neutral. The facets are idling, not working: we sidebend, let us say to the right, and what happens? (Remember there is a superimposed load-don't forget that). The bodies rotate to the left, that is, they move in the line of least resistance and crawl out from under the load as far as the ligaments and muscles will permit. As Lovett says, they behave like a pile of blocks. Second, take the dorsal with its posterior curve. Put it in neutral and sidebend, and what happens? Just what happened in the lumbar, except the articulating facets in the dorsal do not permit quite as free rotation and a little freer sidebending than the lumbar facets; still the same thing happens that happened in the lumbar. Third: Now we will take the cervical with its anterior curve similar to the lumbar, put it in neutral and sidebend, what happens? The bodies rotate out from under the load and to the convexity, just as they did in the lumbar and thoracic, except as to degree, here again the facets permit a little less rotation than in the dorsal and a little more sidebending." Now let us see if we can compile this into a law. In the lumbar when the spine is sidebent from neutral, the bodies rotate to the convexity and crawl out from under the load. The same thing happens in the dorsal and in the cervical, so we may say: When any given area of the spine is put in neutral and is sidebent the bodies rotate to the convexity. The sequence is neutral, sidebending, rotation - never in any other order. Now let us observe what happens when we put these three areas in extension, that is when we straighten out the normal curve, and sidebend. Let us take the lumbar first. We bend the lumbar forward until the facets are separated to the limit of motion, then we try to sidebend but we cannot until we rotate slightly in the direction of sidebending, or toward what is to be the concavity. Therefore in extension, we rotate and sidebend in the sequence of extension, rotation sidebending - never in any other order. Now let us take the dorsal. We extend the normal curve by backward bending. In this position the facets are approximated to the extreme limit and are in control of motion, even more than they were In the All Rights Reserved American Academy of Osteopathy® 37 lumbar when they were separated, because in extension of the lumbar curve the weight is increased on the discs, whereas in extension of the dorsal curve the weight is diminished on the discs, and therefore, the facets have less stress to overcome in rotating the body to the concavity, so that It can sidebend. (Important! This accounts for the fact that we have many more extension, rotation, sidebending lesions In the dorsal than in the cervical and lumbar.) To extend or straighten out the norma1 cervical curve we bend the head forward. The cervical area behaves as the lumbar area did, except as I have said, the structure of the cervical permits more sidebending and less rotation than the lumbar. Then we arrive at this conclusion, which Is really a law: In any area of the spine when the normal antero-posterior curve is put into extension the bodies of the vertebrae must be rotated toward the side to which the spine is to be sidebent before It can be sidebent, Therefore, when any given area of the spine is put in extension rotated and sidebent, the sequence of operation Is extension, rotation sidebending never in any other order. "If the spine be cut posterior to the bodies, according to Lovett, the posterior part acts like a flexible ruler or corset stay which must be twisted in order to be sidebent. The anterior part, the bodies, acts like a pile of blocks which if sldebent tends to crawl out from under the load, or go to the convexity. This is the anatomical explanation of the physiological movements of the spine. Lesions are produced by the inexorable pull of gravity on the unstable human spine in one or the other of these two patterns. The action of gravity must be considered in every lesion. Gravity is the force and anatomical structure is the guide which makes the spine behave as it does in the physiological movements. Gravity tends to make the spine collapse, while the structure of the spinal column determines the nature and extent of the deformity. Gravity causes lesions to develop in one of the two physiological patterns described, depending on the position in which it finds the spine. It is the most pernicious influence acting on the body." The reason for distinction between a lesion produced in extension and one pro- duced in neutral is obvious, because of the difference in direction and sequence of rotation of the vertebral body in relation to sidebending. The reason for distinguishing between a lesion produced in extreme flexion and one produced in extension Is not so obvious and may be the point where some of his students fail to understand completely Fryette's idea of correction of lesions along physiological lines. From the fact that the spine acts similarly when it rotates and sidebends in extension and extreme flexion, it might be concluded that correction of a lesion in both cases should be identical; i.e., extension or extreme flexion, rotation sidebending in the reverse of production. This conclusion would be true if one circumstance did not prevail which changes the conditions; i.e., the impossibility of the body maintaining extreme mechanical flexion for any considerable period of time. The extreme flexion of the original lesion soon changes to moderate flexion. When the area of the spine where the lesioning occurred moves either into moderate flexion or neut ral the mechanics of the back force the bodies of the vertebra Involved to move, under the pull of gravity, from the concavity to the convexity and we have a lesion of the neutral type in flexion. Dr. Fryette says he has never actually seen a lesion of the extreme flexion type with the bodies rotated to the concavity in forty years of experience. "For all practical purposes extreme flexion, rotation, sidebending lesions may be disregarded in treatment." A large majority of all lesions of the spine are either (1) flexion, sidebending rotation lesions, or (2) extension rotation sidebending lesions. Treatment is applied by placing the spine in the proper degree of extension or flexion and reversing rotation sidebending or sidebending rotation, depending on the type of lesion, to permit the lesioned vertebrae to be carried into normal relationship. A clear diagnosis of the lesion described in terms of the physiological movements tells exactly in what position the spine must be placed and automatically commands a certain accurate corrective series of movements. It contraindicates other movements as superfluous and incorrect.

All Rights Reserved American Academy of Osteopathy® 39 (3) Correction reverses these physiological motions. These are the fundamentals. Each artist in the field of osteopathic technic uses these or very similar fundamentals when he corrects a spinal lesion as a basis for the refinements which make his treatment a thing to be admired and appreciated by the patient. If it can be so taught, students will readily acquire an appreciation of technic they may never obtain from an unorganized presentation, no matter how skillful and even spectacular the demonstration may be or how eloquent the lecture which accompanies it. Teaching Technic Technic must be as carefully conceived and as reasonable as the diagnosis which precedes it. A good diagnosis is futile unless it is implemented by good technic. The teacher must train the student so he will know how to give a good treatment under any and all circumstances. How can this be done? Obviously it is an impossible task to teach specific treatment for all types and degrees of disease. What then is the answer? A physician can be proficient in technic if he understands the principles involved and is able to apply them. A good physician can devise a procedure accurately adapted to the needs of each specific situation, whether he has encountered it before or not. If he is able to make a specific osteopathic diagnosis, he can give a specific osteopathic treatment and if the diagnosis has been correct the treatment will be beneficial. Therefore, the teaching of technic should consist first of principles and second of practice in translating these principles into action. If he learns these lessons well, the student may then give an intelligent treatment under any reasonable circumstance. The fundamentals of technic as applied to the osteopathic articular lesion are simple,* though the technic may be complex. A few elements can be compounded into many complex actions. By careful diagnosis, the bony displacement at the articulation, the limitation of motion and the alteration of the condition of the soft tissues can be determined. Also with experience the effect of the lesion on the body economy and the general health of the patient can be evaluated and the desirability of a change in the lesion decided. This knowledge indicates what the technic shall be. Corrective articular technic implies specific motion. This means in articular technic that some mass is moving at some rate over a certain distance in a certain direction. Diagnosis tells what to move at what rate and in what direction and how far. Technic is the action of the physician doing what diagnosis indicates. For example, if diagnosis indicates that a vertebra is in lesion in such a way that the area is extended, rotated and lateroflexed to the right and is held by tissues exhibiting the characteristics of an acute inflammatory reaction of considerable intensity, a course of action is indicated by the changes found. Likewise, if the vertebra is extended, rotated and lateroflexed as before but is held by tissues showing the effects of chronic inflammation another course of action is indicated. Although both lesions are diagnosed as extension, rotation and lateroflexion to the right the treatment varies considerably. What is to be moved and the direction and distance of the motion are determined by the positional diagnosis but the manner of moving it and the treatment of the soft tissues is influenced by the conditions of the supporting tissue as well as a consideration of the systemic effect of the movement. An athlete and an old lady may have similar local lesions from the standpoint of relative position of the parts but technic of treatment may vary considerably because the condition of the tissues varies. Furthermore, should the athlete have meningitis and the old lady be in excellent health, the treatment would be further modified because of systemic conditions. Diagnosis finds and evaluates the systemic conditions and determines their relation to the lesion. Also it explores the pathology at the point of lesion. Technic is the means of putting osteopathic principles into constructive action in the treatment of the abnormal * A review of the chapter on Terminology and Diagnosis of Anatomical Changes in the Spinal Articular Lesion will help recall some of these fundamentals. The Chapter on Diagnosis of Pathology in Relation to the Osteopathic Lesion will give others. All Rights Reserved American Academy of Osteopathy® 40 conditions, local and systemic, found by diagnosis. It cannot be applied empirically. No prescription can describe it be. cause in every instance it has to be an original creation designed to meet a specific diagnosis. An articuiar lesion may be corrected in one of two basic ways: (1) Direct technic: the method of moving one bone or segment of the articular lesion directly to a normal relationship with its neighbor. This is accomplished against the resistance of tissues and fluids maintaining the abnormal relationship. It sometimes involves more trauma than the second method to be described. Direct technic is the most commonly taught and used type of corrective treatment. Unfortunately it is too often applied without careful study of the exact relationships and pathological conditions. Shock reactions are too frequent, resulting in increased inflammatory reaction. Direct technic is valuable but it must be used with discretion. It has great possibilities for benefit or damage and its intelligent use requires fine judgment based on accurate diagnosis. (2) Indirect technic: the method of moving one bone or segment slightly in the direction away from the direction of correction until the resistance of holding tissues and fluids is partially overcome and the tensions are bilaterally balanced; then allowing the released ligaments and muscles themselves to aid in pulling the part toward normal. Other body forces including that of respiration may be employed. It is the type of technic described as "exaggerating the lesion" before correction although actually the lesion is not carried beyond the point where the insult took place which produced it and exaggeration does not actually occur. The "exaggeration" is done to relieve as much as possible the tensions which maintain abnormal relationship preceding the enlistment of the natural pull toward normal. During correction, if diagnosis has been accurate, the 'displaced part should retrace the course it took in becoming lesioned. Therefore, shock and inflammatory reactions seldom result from careful indirect corrections, especially if done with respiratory cooperation. The teacher of technic should indicate clearly which type of technic, direct or indirect, he is demonstrating and should explain why he has chosen it, with due consideration of the abnormal conditions present and the condition of the patient. What has been said previous to this point has applied to the spinal lesion and to reduction of articular displacement. It has been stated that accurate diagnosis indicates the treatment. This is of course true of any lesion. However, there is another consideration in every treatment that must be definitely decided. It is this: How much and what kind of soft tissue work is to be done and at what point in the treatment is it best used? Each physician must answer this question during each application of treatment. The instructor must be prepared to help the student decide it. What the teacher says will depend on the instruction he himself has received and his own experience. Certain things must be considered before teaching the use of soft tissue treatment. First, for our purposes, in teaching technic let us eliminate visceral and other ventral structures from consideration and define soft tissue as tissue not bone or cartilage related to the joints in lesion, confining it to muscles, soft connective tissues, nerves, blood vessels and and fluids affected by and helping maintain the articular dysfunction. Second, let us understand that all technic of correction of joints is applied to and changes only the soft tissue. This is true of the work of the so-called specific technician who says he moves bones only and never does soft tissue work. Third, since Burns* has shown from animal experimentation and Kauffman** has reasoned from a review of the literature that manipulation of soft tissue may cause local harm by increasing inflammatory reaction and blocking the lymphatics, unwise manipulation may cause an * Louisa Burn's experiments on rabbits show any corrective manipulation to lesioned areas produces inflammation as evidenced by increase in petechial hemorrhages. ** C. H. Kauffman in "A Discussion of Osteopathy and Its Relation to Physical Medicine" maintains that most so-called physical therapy as well as drug medication, blocks lymphatic6 and disturbs the vasomotor and proprioceptive impulses originating in the area. All Rights Reserved American Academy of Osteopathy® 41 increase of pathology and dysfunction. Fourth, some so-called corrected lesions are actually chronic lesions with attendant decrease of pain and apparent though not actual improvement of function, this chronic condition having been hastened in its development by unwise treatment. From these facts we may reason that any manipulation of a lesion will irritate soft tissue to some extent and should therefore be used with understanding and for a definite purpose. Soft tissue work itself must be specific. The recommendation that unindicated manipulation be avoided because of possible damage to soft tissue, does not mean that soft tissue treatment is to be eliminated completely. Soft tissue pathology frequent ly is the cause of recurring articular lesions either by direct mechanical effect or by reflex action to related structures. These soft tissue lesions must be corrected if diagnostic evaluation shows they are causing functional adisturbance, however remote that may be. Like any osteopathic lesion, the corrective measures are specific. What should be done, is done; no more, no less. There is no excuse for thoughtless and routine work. Technics of treatment of the viscera, like specific articular and soft tissue technics, are directed to the correction of definite anatomical displacements or pathological conditions. As in any tech. nit, an intimate and accurate knowledge of the exact anatomical relationships found and a careful correlation of these findings with observed dysfunctions, directs the physician's effort. Each organ presents specific problems and is worthy of close study to find how it may best be assisted in maintaining normal function. There are fields of technic which need exploration and development. Wales* has suggested that natural forces in the patient's body be made use of by the physician. New concepts developed in recent years are being brought to the profession. Sutherland has pioneered. in cranial technic and Chapman in his so-called reflexes. These methods need discriminating study and development and more general appreciation. Exaggerated breathing as an aid to manipulative technics in anatomical correction in any locality has been advocated because respiration is a physiological movement and as such should be considered in technical procedure. Development in technic as in any creative art needs imagination to give it originality and meaning. The teacher should bring out this quality in the student. He will then have given the younger physician a priceless tool, adaptable and effective according to the ability and interest he shows in using it. In technic instruction, an exact description of the lesion in question is first required. This includes both anatomical and pathological changes. Second, the effect of the lesion on local segmental and systemic function and structure is postulated and the advisability of correction determined. Third, the method of correction is described and justified by reference to the previous diagnosis, which indicates the technic to be used. Fourth, the manipulation is done slowly. Each step is mentioned but not discussed in detail at the time. The steps may be repeated in most cases without harm if the work is carefully done. Fifth, the four preceding steps are now recapitulated and questions answered. Sixth, the student may practice what he has learned on appropriate subjects, being watched closely with the view of preventing the formation of wrong habits and encouraging the habit of independent thought and reason as it directs accurate hands to intelligent action. It may seem to some instructors that this makes technic teaching too intricate and difficult. Let those who so think consider the number of mystifying or misleading demonstrations he has seen put on by clever and intelligent people using less exacting methods. Let them remember that accuracy in treatment and the ability in diagnosis which it implies is the hall mark of the osteopathic physician. Without it he is futile. With it highly developed, he is without peer. * Osteopathic Dynamics--Yearbook Academy of Applied Osteopathy 1946. All Rights Reserved American Academy of Osteopathy® THE USE OF "THE PATTERN" IN TREATMENT OF AN ACUTE TRAUMATIC LESION H. V. Hoover B.S.,D.O. After the physician has decided that an osteopathic lesion exists and that change is indicated, the exact treatment to be applied must be determined before corrective forces are used. Diagnosis dis closing the path of physiological movement of production of the lesion and the physiological and pathological changes in the local and remote related tissues indicates what disturbance exists and the direction and type of force applied for correction. If the parts were in normal postural relationship before the insult which produced the lesion occurred, obviously they should be returned to normal conditions and position. But if, as is more frequently the case, the parts were conditioned by long standing postural strains before the lesion under consideration was produced, treatment must be modified in consideration of the pre-existing conditions. This calls for careful evaluation of existing and pre-existing conditions as a preface to the application of treatment. Normal posture is a rarity. Certain curves, tensions and balances in time become fixed characteristics of the posture of the idividual. These changes from perfection in posture are the answer of the defensive mechanism of the body as it resists the pull of gravity and other forces which may act on it. Similar conditions such as, for example, an uneven sacral base or an uneven occipital base tend to produce characteristic patterns of compensation in the spine and cranium. These basic patterns are perversions of structure but because of their slow development and the ability of the body to adapt to slowly occurring change, they may not cause recognizable disturbance. However, if upon these basic patterns a new lesion is superimposed, symptoms develop not only in relation to the site of the new lesion but in other parts of the pattern, thrown out of balance by the new lesion. These 'symptoms bring the patient to us demanding relief and the new conditions causing them are what need treatment. If the new lesion can be removed by placing the parts in the relationship and condition obtaining in the old pattern and the imbalances resulting from the new lesion removed from the old pattern, the individual should be quickly relieved of his newly acquired pains and functional disturbances, although still retaining his original postural deviations from normal. To clarify this point let us consider two cases. Case 1. A patient presents herself with an acute "catch" in her back, brought on several hours earlier in the day by lifting a small box while stooping in a cramped position. The history reveals a weak back which is stiff and tires easily. There have been previous episodes of similar "catches" which however were not as severe nor as incapacitatirig as the present one. The patient because of pain which has steadily grown worse since its onset, needs assistance even to change position and has difficulty preparing for examination. Xray is indicated but pending the report something must be done. General physical examination reveals nothing which would cause the severe symptoms. Examination of the back by light palpation shows an acute inflammatory reaction at the level of the second and third lumbar vertebrae. The patient, as well as the palpating fingers, says "that's the spot." Above and below the acute lesion are found evidence of chronic lesioning and careful examination shows that the acute lesion is at the apex of a normal flexion (or neutral) group curve to the left of the midline, which extends from an uneven sacral base low on the left, to the lower thoracic area where the curve crosses the midline and forms a group curve to the right of the midline, the apex of which is at about the 6th thoracic segment and which again crosses to the left side in the upper thoracic; I. e., a typical functional scoliotic type of back. Soft tissue examination reveals chronicity throughout the extent of the back, indicating a postural strain of long standing. 42 All Rights Reserved American Academy of Osteopathy® . 43 acutely lesioned segments are moved into The acute lesion in the lumbar area breaks the symmetry of the curve and obviously de- the relationship they held as a part of the scoliotic curve, knowledge of the physiolostroys the balances set up by the curves compensating for the tilted sacrum.

She says that was where she must have hit her head. Examination was made about a week after the accident. The tenderness in the head is localized to the occipito mastoid area and is due to a severe lesion at that suture and not to a bruise. The rest of the head is sensitive but shows no marked traumatic lesions. There is a rotation sidebending of the spheno-basilar articulation to the left. This rotation and sidebending is not marked but the position and 'shape of the bones of the cranium and face conformed to it indicating a condition of long standing, possibly from birth. The right temporal exhibits internal rotation of the petrous portion more marked than one would expect to find in relation to the mild sphenobasilar lesion. What should be done in this case. The physician has here as in the previous case several choices of procedure. 1. He may use purely palliative measures as ice packs, sedatives, rest, heat etc, which is the only course open to physicians who are not trained cranially. 2. He may use bulb compression to attempt to relieve the fluid and membranous tension. This may be effective eventually but with the head so tender and in the presence of such a pronounced traumatic lesion this method would be used rarely. 3. He may attempt to correct all of the postural lesions in relation to the sphenobasilar and in so doing normalize the acute traumatic lesion at the occipito-mastold. This must be done in some cases especially when the pattern cannot be deter mined accurately or it has been hopelessly shattered. 4. He may free by appropriate methods the temporal and mastoid and permit the natural pull of membranous tensions and force of fluids to bring the bones into the relationship that existed before the accident occurred. These forces will tend to place the temporal in its old pattern which leaves it still in internal rotation. This method secures the quickest and most satisfactory results. The chief point to be noted is that the temporal bone is still in a position of internal rotation after accur ate correction and while in this position the patient gets complete symptomatic relic The later treatment of the pattern itself is a matter of judgment on the part of the physician. He must decide whether it is better to leave the patient with his accustomed pattern or to change it. Many factors other than the reaction of the patient to the injury enter into the decision, as age, general health, stability of the pattern, acuteness or chronicity of tissue reactions, occupation, and financial conditions. It is not always easy to determine whether it is wiser to embark on a program of rebuilding the patient or to leave him as he is. If he is to be reconstructed both the physician and patient should be aware of what it may mean in health, time, energy and money. A Measure for Osteopathic Technic A system or method of judging a technical procedure in osteopathic treatment is obviously of value to the physician. If he can examine a piece of technic and determine if it is physiological in its application, effective in its results and efficient in saving the strength and time of the operator, he is able to accept or reject technics with assurance, and to examine his own procedure with benefit. Thus he becomes more efficient by improved technical methods, appreciated by both doctor and patient. The evaluation of a technic falls naturally into two parts. The first has to do with the question "Is the technic physiological?" The second concerns itself with the effects of the technic on the patient and the doctor. The physiological movements of the spine are known to osteopathic students. Consequently they know the path a segment of the spinal organ follows to reach the position where the insult took place which produced the unphysiological conditions, known as an osteopathic lesion. Since technic of reduction of a lesion should be so designed as to reverse the procedure of production it is clear that the process of reduction of the lesion should take into consideration the elements of the physiological movements of the spine; i.e., flexion or extension, rotation and lateroflexion or other motions possible in certain areas. The soft tissue involved in the correction must be considered and the technic adapted to meet the conditions found so that the application of forces is as physiological as possible. Acutely irritated All Rights Reserved American Academy of Osteopathy® , tissue requires a different approach than does chronic fibrosed tissue. Any technic which does not consider these factors in reversing the motion of lesion production and the state of the soft tissue is deficient. Any good technic includes them whether the physician is conscious of it or not. For instance, a technic designed to correct a rotation lateroflexion of the second thoracic segment on the third thoracic which does not take into consideration the component of extension or flexion is doomed to failure. This is because of the fact that if the lesion was produced in extension (or flexion) it should be correct. ed by taking out the extension (or flexion) at the same time the rotation lateroflexion is eliminated. Otherwise the lesion persists in a modified form. The operator then wonders why his correction is not permanent, often blaming factors other than his own lack of care in diagnosing and correcting all components of the lesion. Also if acute spasm or fibrosis prevents correction it is useless to attempt it until the soft tissues are properly treated. The second part of the evaluation concerns the effects of the treatment. To the patient the procedure must be primarily beneficial and secondarily comfortable. To the doctor it must preserve primarily his health and secondarily his time. The improvement of the patient's health is the primary reason for administering a technic and under extreme circumstances is the only consideration. But lacking emergency, the physical and psychic comfort of the patient deserves consideration. The technic least likely to cause pain should be used, if a choice is possible. Also if one technic may embarrass the patient and the other not, the embarrassing one should be discarded. Some patients dislike bodily contact. Some dislike "popping" of joints. These and other factors may modify the application of treatment. The doctor before using a technic must consider whether the resulting benefit to the patient warrants the drain on his own strength and vitality or if some less taxing method, perhaps only slightly less 45 effective, may be sufficient. Also, if the condition of the patient may be changed for the better in a few minutes it will be foolish to use a technic no more effective but requiring a longer time, providing the shorter one is not uncomfortable to the patient or too taxing to the physician. To summarize, a technic must be proven to be physiological. It is to be judged for benefit and comfort of the patient and for the effect on the health and the use of time of the physician. To be efficient each physician should constantly evaluate his own technic to see if it meets these requirements. If it does not meet them, he should make it do so. Postscript Before I came to the end of the task of writing these pages, I realized that they were being written, not so much for the profession in general as for one member of the profession in particular who demonstrates technic occasionally, writes articles about it at times and has attempted to teach it. What started out with the idea of pointing out some observationsand opinions on technic to demonstrators and teachers, became a means of crystallizing amorphous and unsystematized ideas previously floating about in the author's mind. He has in this process received considerable benefit. I recommend to every physician who wishes to progress and develop professionally that he put his ideas on paper. The process will bring him to the realization of the need for improvement, as nothing else will. This is not the last word on teaching osteopathic technic. It is merely intended to open up a question which has received too little study and consideration in the past. It is the author's hope that it will be the starting point for a serious examination of the technics and teaching of osteopathy to the end that the graduates of our Colleges and as far as possible, the practicing physicians may be taught how to deliver more effective osteopathic treatment. All Rights Reserved American Academy of Osteopathy® THE CONTRIBUTION OF CARL P. MCCONNELL, D.O. TO OSTEOPATHIC LITERATURE Anne L. Wales, D.O. Carl P. McConnell, D.O. from the be. ginning of his professional career, contri buted to the advancement of Osteopathy. He was born in West Salem, Wisconsin in 1874.. While studying science at the University of Wisconsin his eyes began to fail him and grew progressively worse although he was under a specialist's care. He became a patient of Dr. C. E. Still when Dr. Still was located at Red Wing, Minnesota, and improved rapidly. This experience engaged his interest in Osteopathy and led to his matriculation in the American School of Osteopathy in Kirksville, Missouri, in the fall of 1894. Dr. McConnell graduated with the class of 1896 and practiced as an assistant to Dr. H. M. Still for several months in Chicago, Illinois. He held the chair of Theory and Practice in the American School of Osteopathy for two years and served at the same time on the staff of the A. T. Still Infirmary. In the fall of 1900 he located in Chicago for the private practice of Osteopathy. Dr. McConnell was president of the American Osteopathic Association during the year 1904-1905. As president of the young association he acquired a knowledge of the problems of the profession and a perspective from which he evolved a philosophy for the development of the science of Osteopathy. His views and his evaluations are not only illuminating in an historical sense but they also reveal the fact that the profession today is still concerned with the same processes of development. In the following address, which Dr. McConnell made before the Greater New York Osteopathic Society while he was president of the A.O.A., he shows the breadth and depth of mind which he subsequently applied to great purpose in furthering the teaching of Dr. Andrew Taylor Still. It is possible to see in his argument why and how he came to devote himself to research in osteopathic pathology. The fruits of Dr. McConnellls labors are to be found in osteopathic literature over the years following his year of office. It is hoped that this rich contribution will be progressively retrieved from the archives and made available to the profession today in a series of condensed reviews for the Academy of Applied Osteopathy. For the works of such minds cannot serve their full purpose unless they live on in the minds of those who follow in the same service. The following paper has been chosen as an introduction to the projected series because of the comprehensive view it offers not only of the author but also of the problems and the field to which he applied himself in later works. It is condensed and edited to a slight degree in the interests of smoother reading. The full address appears in the Journal of the American Osteopathic Association, Vol. 4, No. 8, page 288, April, 1905. Limitations of the Osteopath An Address before the Greater New York Osteopathic Society, December 17, 1904, by Carl P. McConnell, D.O. In discussing the limitations of the osteopathic practitioner, let it be clearly understood that I am in no way referring to the limitations of Osteopathy, for I firmly believe that the science of Osteopathy is the system of medical science and art that completely and absolutely includes and is applicable to all the field of medicine in its broadest sense. Dr. Still is unquestionably the originator of the theory that the character of structural relations and alignments is a true basis of the etiology of disease. The point I am desirous of emphasizing is that the drug school's teaching of the past decade is unmistakably leaning toward the osteopathic. 46 All Rights Reserved American Academy of Osteopathy® 47 Neither am I to discuss the limitations of the osteopathic theorist, for he is in an advanced class by himself. Fortunately for Osteopathy we have always had B good theorists and not a small portion of our inspiration has been due to them. They have continually held before us (and thus illumined our way) a delineation of the logical path of osteopathic development. This has been no small part. The evolutionary tendency of osteopathic probabilities and actualities has been a guide to all practitioners that boded much good. Practically all of our work has been pioneer work. Case after case has come to us which we should be able to cure or benefit according to our philosophy. What then would we have done without our theorists? No one aside from Dr. Still had the experience to support our decisions. Consequently, judgement based upon practice had to be substituted for the time being, by logical deductions. Our philosophy has been stated in such clear, concise, and simple terms that even the layman has been able to grasp its logic and significance. Of course our theorists have had anatomic, physiologic, and therapeutic facts on which to base their theories. It is true that our theorists could not have written so forcefully and appealingly if our practitioners had not obtained results. As stated, our theorists are in a class by themselves, and well they should be, for a theory in its proper use signifies the highest form of knowledge. Our paper then is to be a discussion of the actualities that confront the osteopath in the field and point out a few of our limitations or weak spots, as well as to suggest a remedy for them. What Confronts the Practitioner There are genuine problems which confront the osteopath in the field. A discussion of these will help to broaden and develop us all. To the studious practitioner must we look for the real advancement in Osteopathy. The practitioner represents the unit in our profession and his welfare and relations constitute the basis of practical Osteopathy. Not that our colleges are unnecessary and do not represent the highest type of education, but their special function is to teach and crystallize osteopathic thought and theory. The practical test of our therapeutics, the test of real worth and value, falls upon the field member. It is true that our colleges aim to turn out capable practitioners; and their efforts have been crowned with success. But no matter how practical a college course may be there are always a thousand and one problems the graduate will meet only in the field. His tact and judgement will often be taxed with problems quite foreign to clinics and theories. Often upon his decision of these problems will his success as a practitioner depend. Not that I depreciate thorough scientific education, for no one appreciates it more than I, but there is another part of education, tactful and practical education, which is dependent upon a balanced brain, and without this one's perspective may easily get distorted. This side of the education can be developed to the maximum in the field; it can be included in the college course to a minimum extent only. Thus a classmate whose college examinations were of no particular credit may be a successful physician provided he has a thorough comprehension of practical Osteopathy backed by mature judgement. Consequently, there are problems arising with the field practitioners that our college professors may be largely strangers to, and still at the same time the evolution of Osteopathy is dependent upon. The osteopathic theory is not supported in all detail instances by a series of established facts; if it was, abstract principles of the science would not be necessary, although we are in the unique position of having a dearth of theories to explain definite and exact results obtained in practice. (It should be noted here that I am not referring to the general theory of Osteopathy.) In drug medicine it is usually the reverse; practice is largely deduced from theories. The only point in common of the various schools of practice in medicine is the induction of principles from the results of practice, of which the osteopathic stands by far the foremost. Unless the general principles or theory of a science is based on actual results, the so-called exposition may be nothing but a false fabric. Hence, one of the reasons why the science of osteopathy is logical and in All Rights Reserved American Academy of Osteopathy® 48 many instances drug science illogical is because the former is deduced from actualities and the latter is nothing but hypotheses. The Practitionerls Limitations I. His conception of Osteopathy One's success in practice will depend almost directly upon his conception of the science; that is to what extent and in what character the concept has taken root. He may be able to appreciate that Osteopathy is applicable. superficially only, to health and ill health. Although his belief in the science may be firm in what he terms a limited application, there are others whose application may be extensive and comprehensive of all physiological functions. The statement may be logically made, that if Osteopathy is applicable superficially and fragmentarily, it is applicable consistently to the whole. The same basic principles apply to one part of the body as to other parts. Lack of osteopathic education or little, experience can be the only reasons why due appreciation of osteopathy as a complete system of medicine is not forthcoming from the honest practitioner. If one's conception of osteopathy is not based upon logical, sane, and broad grounds, that practitioners' usefulness and ability is limited. He can do justice neither to himself nor to his patients. This is the member who so readily chases therapeutic rainbows. His osteopathic basis is not solid. Even if he tacitly admits that the system is partially right, he proves his lack of logical reasoning and thorough understanding by not admitting more. Real osteopathic work cannot be partly right; the system is a science or it is not, for the simple reason that its truths either do or do not permeate consistently in all functional and organic The entire body is controldisturbances. led and governed by the same dynamics, whether the extremities, the chest, or elsewhere; and consequently, one system or character of forces does not provide functioning in one locality and other systems somewhere else. The body economy is regulated by definite and precise law; its equilibrium is rigidly maintained in character; the transference of body energy is according to exact rule. Consequently, it is preposterous to intimate that osteopathic principles are only partly right, for. its fundamentals are absolutely harmonious with the fixed laws of nature. The laws of mechanics and through them the exchange of energy from the physical plane to the therapeutical plane is just as applicable to one part of the body as another. Ehysical energy transferred to a physiological or therapeutic equivalent through anatomical adjustment, stimulation, or inhibition is appreciated as much in one tissue as another. Therefore, osteopathic therapeutics are not fragmentary, except as the practitioner may ignorantly apply them. These statements are certainly elementary, but it seems that at the present stage of osteopathic development a comprehensive and consistent understanding of fundamentals is, in some quarters depLorably lacking. Our practitioners' education and enthusiasm should be osteopathically The inconsistent broadening rock-ribbed. out process should be stopped. I refer to the catch-penny freak practices of a few of our colleagues. Legitimate 0steopathy contains problems to be solved that will keep the profession extremely active for generations. Our desire should be to awaken a thoroughly scientific spirit in the field practitioner; then mercenary motives will be reduced to a minimum and the good done Osteopathy will be invaluable. In a 'conversation with Dr. Still only a few weeks ago he made the statement that it was his belief that the man who sought truth for truth's sake would always be provided for. Could a more inspiring statement come from a scientist and a philosopher? Hasn't his life been a shining example? Hereditary customs and traditions are potent factors in the present medical development. Because of this it is hard for some of us to thoroughly and consistently apply our science unless we are dyedin-the-wool osteopaths. The courage of our convictions is in danger of being neutralized through inheritance and present customs and environment. On the other hand, there are practitioners who are such extremists that they occasionally attempt the impossible through osteopathic therapeutics. They encroach, for illustration, upon the distinct field of surgery. The reason for this is a distorted perspective. These practitioners, All Rights Reserved American Academy of Osteopathy® 49 however, make a much greater success than those who are constantly seeking the limitations of applied osteopathy. After a few mistakes they find the true perspective a point where mature judgement backed by experience tempers the work. And where are the practitioners who do not make mistakes? These men and women become our safest and best physicians, for they start with a foundation that is true, and in a short time practical experience polishes their technique, renders judgement more infallible, and quickens decision. There is a class of osteopaths who are constantly impressing upon others what Osteopathy cannot do rather than what it can. These individuals get the "cart before the horse". Caution is always advisable, but to twist the logical sequence of facts about so that emphasis does not fall upon primary factors is a mistake and ultimately leads to much indecision and lack of executive.ability on the part of the practitioner at the bedside. III. -His narrow - conception -of osteopathic etiology. We should continually hold before us a broad basis of osteopathic etiology. Broad in the sense of being comprehensive but still consistent with osteopathic standards. It is so easy to forget or not even realize that the very nucleus of osteopathic originality is our idea of etiology. Osteopathy is not characterized alone by a unique and distinct terapeusis; that is a secondary feature. The primal characteristic of Osteopathy is exhibited in the retognition of an independent etiology. This is the distinction between Osteopathy and other schools of the healing art. Therapeutics cannot be developed and evolved without a base or starting point. Our therapeutics, owing to their radicalism, are apt to eclipse the greater portion of osteopathy, our etiology. The spectacular exhibition of manipulation, stimulation, et cetera has outshone the greater part, osteopathic etiology. Also the general treatment weakling has attempted to cover II.

Alas! tations, instead of adding his manhood weight to the real elaborating of our science, is beyond me. It must seem that the scientific perspective of such a one is All Rights Reserved American Academy of Osteopathy® 50 entirely embryonic. One of the purposes of this paper is to briefly speak of several etiological factors germane but still usually secondary to the great primal cause of diseases, deranged tissues. My object is to specially call attention to forces and agencies that we should recognize and study more than we do. An understanding of these will help to round out our appreciation of disease processes. A) -Cosmic forces I speak of cosmic forces in order to emphasize that one's horizon should not be too narrow. There is danger on the one hand that the practitioner may become hypnotized by details and thus lose sight of the relation of the part to the whole. The student is so apt to become lost in the maze of details unless his instructor has the ability to occasionally lift him above the minutiae and show him relative values and place emphasis where it should be. On the other hand, there is also the danger of observing generalities only. This quickly leads to superficiality and superficial work in osteopathy is represented by the general treatment and trusting to luck. Vis medicatrix naturae, fortunately for the patient but detrimental to the practitioner as a scientific physician, often comes to one's aid. The physician who can most nearly arrange the logical sequence of factors to the ideal is without doubt the sanest and safest physician. Cosmic forces play a part in influencing health, although just what the forces are and how they act is largely unknown. Pandemics and epidemics are certainly influenced by such forces. They leave many chronic sequellae behind them to manifest later. Unhygienic surroundings,unsanitary conditions, poor food, and polluted water, atmospheric and electric changes with other disturbances of an universal nature, disturb physiological harmony and may overwhelm it. The powers of nature, gaseous contents of the atmosphere, abnormalities of air pressure, et cetera are probably potent forces in influencing fluctuations of disease, periodicity of epidemics and the like. Of course fear of infection is an important factor in increasing susceptibility to disease. It is interesting and well that we should bear these things in mind. Someday these prob- lems will be solved. Until they are a recognition of their influence will aid us materially in treating diseases. 3) Heredity Whether heredity is cumulative, mediate, or immediate it has often been overlooked by the osteopath. There are two good reasons why we have been at fault here; first, the medical profession has attempted to make too much of heredity and' second, the. osteopathic practitioner in the field has found that previous medical diagnosis was wrong particularly where an M.D. has said the condition was inherited and the osteopath has been able to absolutely rectify the condition. Thus the oisteopath has minimized hereditary tendencies. We are somewhat given to being hasty in our diagnosis and making 'snap judgement decisions, instead of studying our cases more and arriving at a decision after deliberate judgement. Although the anatomical evidence is so clear that 'we may be justified in making quick diagnoses, it is well to deliberate only after collecting all the facts, including laboratory findings, in a certain percentage of cases. We know that family traits are occasionally pronounced for many generations and also racial characteristics. Certain families and certain races are more prone to diseases that others are not so susceptible to. The explanations are wide and varied but we should remember that it is usually organization of anatomical and physiological features that are inherited and not diseases, with few exceptions. What does this teach? It teaches us to be more careful in diagnosis, and as a consequence our treatment will be more rational. Literally ramming ahead and giving a treatment regardless of a definite course to pursue and object in view is ignorance inexcusable. It has been said that constitution is the state of the human organism from the moment of birth to death; it is "the resultant at any and every moment of the interaction between the organism and its environment." "Environment is the sum of the circumstances affecting the organism from birth until the moment under consideration." "Heredity is the state of the organism as determined by the ancestors." Constitution is always changing; heredity is fixed and determined. Diathesis is fixed and determined; this represents intra- All Rights Reserved American Academy of Osteopathy® 51 uterine history, and "is a state intermediate between heredity and constitution." C) Predisposition A predisposing factor whether due to natural or congenital causes may be a potent one. A diathesis is not a disease but a condition or tendency. In preventive medicine the predisposing condition is of the utmost importance, and preventive medicine is a field so far little developed but its possibilities are tremendous and Osteopathy holds the key. The time is rapidly approaching when the layman will go to the osteopathic physician for examination and possible preventive treatment somewhat similar to the lay-man's relation to his dentist, knowing that a little prevention often saves immeasurable suffering. No one will question that the true osteopath is the ideal person for this service. We are especially well fitted for eliminating and correcting predisposing causes. Anatomical malalignments and deviations are our main forte, and a large percentage of predisposing influences are directly traceable to an unsymmetrical physique, consequently osteopathic manipulations are peculiarly applicable here. Anatomical predisposing factors are such an integral part of prophylaxis that our practitioners should be alert in this field. Defects in standing, sitting, and walking are potent forces in paving the way for insidious and positive beginnings of ill health, so we should be constantly on our guard. D) Environment There are cases where osteopathic lesions are well marked but relief is practically impossible until the environment of the patient is bettered. We are apt to get heredity and environmental influences confused, for often the effects of either of the forces are mixed. It is well to keep in mind that rarely is a disease inherited; but a special tissue weakness may be inherited with a consequent predisposition to diseases common to the defective tissue which through environment will be the direct means of developing the disease. The same would be true of any impoverished body that is housed unduly, given poor food and constantly coming into contact with pathogenic organisms. The real surprise is that there is not more disease than now exists. Certainly the body will stand much abuse. Environment is really a stronger and more common factor in producing disease than heredity. As osteopathic physicians we should lay special stress on environment. Do not ignore it. It is in absolute harmony with osteopathic tenets, -in other words with common sense. All of us suffer from the lack of a simple life. The modern hurly-burly of the city keeps one on a constant tension both mentally and physically, and the chain of symptoms and diseases that can be directly traced to this kind of life are well known. E) Hygiene and sanitation Hygiene science of health and its preservation, and sanitation, the establishment of conditions favorable to health, are broad subjects. It is not my purpose to reiterate established and well known practices but to awaken in our practitioners an interest for a wider field of usefulness. We are not doing all that is possible. Our practitioners are capable of a greater and better work than they are now doing. Distinctive osteopathic etiology and therapeutics we will grant, if practiced alone is a specialty. But Osteopathy as a school of medicine is not specialism. No doubt that osteopathic therapeutics as practiced by a number is clearly limited in applicability. This suicidal tendency is just what we must avoid. Our future is before us and there is not a doubt but that we can make of it what we will. We can specialize in the osteopathic school as in other schools. But to say that osteopathy is a specialty by virtue that our characteristic work is manipulation is not logical. We treat both acute and chronic diseases with equal success. The treatment is not limited to diseases of any one tissue or section of the body. Neither are we a sect. True we follow a leader in our distinctive work but there is much other ground that seems to be a stumbling block to many. These practitioners must raise themselves from the thralldom of sect. We would be a sect if we blindly or absolutely followed a leader, if we practiced the characteristic manipulations of Dr. Still only. Dr. Still has never asked us to follow or imitate his individual practice. He has given the All Rights Reserved American Academy of Osteopathy® 52 world a general theory of disease, a philosophy that is as broad as the universe. He has asked us to apply this theory to all diseases, to all sciences pertaining to the medical art. It has been tried and not found wanting. Our venerable founder is always ready to appreciate medical facts from various sources. We are a school or method of practice, a system if you will, for our exhibition of essential principles or facts is complete and arranged in a rational connection and applicable to the entire field of medicine. Thus we should encourage our colleagues to fully round out their practice. True we are followers in our main work, characteristic osteopathic revelations of Dr. Still, and well we should be for he has not only added distinct knowledge to medical science but has given it a theory, established on facts, that is applicable to and renders the whole a rational and logical system. The limitations of the osteopath cover a somewhat large field but still that field is a self-made field in proportion to the practical ability of the osteopath. Hygiene and sanitation are inclusive of much that is of vital moment to the health of the individual and of the community. The osteopath will have to share the responsibility in these matters as well as others if he expects to be classed among physicians. F) Dietetics Regulation of the diet is another important field of work that all physicians should familiarize themselves with. This is no ordinary problem especially with some classes, and we will find that frequently certain disorders of the body will not yield to a successful issue without regulation of the diet. In order to become skilled in diagnosis and prognosis a thorough understanding of pathological processes is absolutely necessary not only for prescribing and executing the correct treatment but also for avoiding the wrong treatment. We must have thoroughly educated physicians. The public is demanding it. Our labor in the sick chamber shows this, that we can successfully treat all diseases. Our success is no more marked in one line than another. Of course, strictly osteopathic knowledge is supplemented by common medical knowledge, but common medical knowledge is our heritage. Moreover, would it not appear ridiculous to ask legislative bodies to legalize and protect our practice if we possessed simply a side show? The evolutionary forces of our science will not allow any retrograde movements. We have deliberately placed ourselves in the breach and we have no alternative but to surge ahead. The potential situation of our science is tremendous and we will not be doing our duty if we do not truly meet the probabilities and possibilities of our school. I am sorry to say that the earnest men and women within our ranks who belittle the resources of Osteopathy are our worst enemies, for a combination of earnestness and ignorance is extremely hard to combat. The lack of pathological science is one of our weak spots. I do not refer so much to medical pathology as to osteopathic pathology. How much real scientific osteopathic pathology has our school developed? Our opportunities are simply unlimited. We have the richest most vital field possible. There is not a member of our association but who is abundantly capable and able to help develop this field. Here we are, four thousand strong and rapidly growing, and have the key to a fund of IV.

By employing these means we fully complete our diagnosis as all physicians should. How can we hope to be scientific men and women capable of advising as family physicians, as hygienists, as sanitarians and the like, if we do not appreciate and understand the import and relative value of all medical and allied sciences? Another point under diagnosis is the fact that many cases of illness tend to recover with or without professional care. The general non-specific treatment will benefit these. The superficially trained physician is too apt to consider his apparent results in these instances as evidence that his clientele requires only the minimum of general treatments to satisfy them. Rather than work conscientiously and give his serious attention to each problem that arises, he grows careless and thus begins the end of his professional career. We should always remember and appreciate the power of Nature but we should not depend upon it to such an extent that we fail to render the best osteopathic care to our patients. VI. His superficial practice of therapeutics. To a degree the therapy of osteopathy has eclipsed more important features of our school. Great stress has been placed upon our therapy with a resultant show of manipulation. Osteopathic manipulation is only a means to an end at best. Unless we have distinct and logical etiology, pathology, and diagnosis our therapy amounts to naught more than massage or movement methods. Inclusive of the lesser importance of manipulation is the great concern we should have for the correct execution of our therapeutics. Many so-called osteopaths have done more to prostitute osteopathy than all other things combined. Through their ignorance they force osteopathy to the manipulative and movement-cure rubbish heap. Their one desire is to know what movement to give for this disease or that disorder. Osteopathy offers a clean clear cut method of treatment as exact as the laws of dynamics and mechanics upon which it is based. Too often the incidenta. work of relaxing and stretching of tissues and methods of stimulation and inhibition are made the greater part of treatment. For- tunately for the patient at the time, but unfortunately for the welfare of Osteopathy, this general pommeling may result in permanent good by inadvertently correcting deep structural disturbances. In our therapeutical endeavors we should always remember that there is a comcatenation of the different physical systems. The nervous system "binds together all the other systems of the body in a living reciprocity of energies and Our therapeutics are peculifunctions." arly harmonious with natural laws so that an adaptation of means to an end is most readily forthcoming. Specific treatment always illustrates this. General treatments and movements are the great impediment to developing scientific Osteopathy. I believe genuine osteopathic treatment coupled with right living, proper environment, and correct food will invariably result in the maximum amount of good in all medical and many surgical cases. Just in proportion to one's divergence from these practices will his success be minimized. The Remedy I am well aware that my paper has been one of criticism rather than of praise. But it has not been adverse osteopathic criticism. We should examine the niches of our superstructure occasionally and, note what it needs in order that it may be more symmetrical and beautiful. I do not-believe one of us realizes the extent of usefulness that our beloved science will occupy in the future. We must keep the science intact and undefiled. There is a class of osteopathic practitioners which seems to fear that those who are earnestly striving to practice pure osteopathy will become narrow minded. They continually preach the efficacy of other methods and ludicrously place some hobby on a par with Osteopathy. The relative value between Osteopathy and these faddish methods may be likened to the light given off by the sun as compared to a star of the fourteenth magnitude. Why they devote their energy to some incidental matter and not to the real magnificent problems of science is beyond me. Can it be that their conception of Osteopathy is the narrow one? All Rights Reserved American Academy of Osteopathy® 55 On the other hand there is the class of osteopath which is extremely anxious and watchful lest the science become lowered by false practices. This class comprises the bulk of the profession and I am proud to state that my sympathy is here. These men and women are the ones who must guard most zealously the fundamentals of psteopathy. These are the apostles who know full well the illimitable field of osteopathic resources. Hence my plea has been to broaden and deepen the ramifications of osteopathic truths. Not to worship false gods but to hold fast to the tenets of our theory, to strengthen the profession, and still grow and develop as our resources warrant. Far be it from me to advocate things foreign to the basic principles of Osteopathy. My one desire is to be a thorough osteopath, thorough in the meaning of the fundamentals of Osteopathy. Before one can realize and appreciate the illimitable field of osteopathic philosophy, his groundwork, his nucleus, must be more than mere theoretical chimera,- it must be revered with an insight which can be obtained only through thorough, practical, specific results. Thus my criticisms can only be friendly, but with the earnest and jealous desire that every one of us may personally and gradually widen the space between the osteopathic manipulator and the osteopathic physician. The remedy lies in more thorough education. Research is the cornerstone of all scientific development. We as practitioners should continuously strive to broaden our usefulness and to delve into the mysteries of life processes. There are many niches that remain to be filled and if mutual encouragement may be forthcoming, the object of my discourse will be obtained. After all we are limited more from lack of experience than from thorough theoretical ideals. Through all of our observations, studies, and research we should continually keep before us the philosophy of the Science of Osteopathy.

The Osteopathic Concept Viewed Biophysically and Biochemically C H A R L E S H A Z Z A R D, P H . B . , D . O . New York City The science of medicine is founded upon chemistry; the science of osteopathy upon physics. The word chemistry derives from the temples of Chemi, Egypt, where the priests experimented with simple chemicals for the preparation of medicines. But progress in medicine, as related to chemistry, has often gone with halting step. For example, the All Rights Reserved American Academy of Osteopathy® 64 SYMPOSIUM ON THE ART OF PRACTICE discovery of ether took place in the 13th Century, but its value as an anesthetic was not realized until 1846; thus for 500 years men suffered the lack of the good offices of a valuable anesthetic which might have averted untold pain. Magnesium sulphate was known to chemists as early as 1694, but not for 200 years was it found to be an agent of great relief in the treatment of burns, lockjaw and strychnine poisoning. Amy1 nitrite was discovered by the chemist 23 years before the physician found that it could be used to relieve the tortures of angina pectoris. Medicine is founded upon chemistry ; osteopathy upon physics; but whereas osteopathy is founded upon the physics of the body, medicine is founded upon the chemistry of nature; and it is not, �nor has it ever been, founded upon the chemistry of the body, which would have been the only logical basis for a system of chemical medicine. The science of medicine never began seriously to advance until in recent years biochemistry came to claim the earnest attention of the medical �men. “Physiology and Biochemistry in Modern Medicine,” by McLeod of the University of Toronto, the first edition of which was copyrighted in 1918, is apparently the first scientific treatise attempting seriously to apply to clinical medicine the facts of physiology and biochemistry as shown by the words of the author in his preface to the first edition: “Biochemical knowledge is treated . . . from the physiologist’s standpoint, as an integral part of his subject, particular attention, nevertheless, being paid to the far-reaching applications of this latest department of medical science (italics ours), in the elucidation of many obscure problems of clinical medicine.” Certainly this was a late awakening. Osteopathy on the contrary, being founded upon the physics of the body, has always just as truly been founded upon the chemistry of the body; for just as function is founded on structure, a truth which with us is axiomatic, so does biochemistry rest upon biophysics. We say, in the words of Deason, that “perverted structure perverts function by perverting the cellchemistry.” In the simple phrase of Still, “The body has its own drug store; the osteopath sees to it that this drug store is well run”; and this, “Disease is the result of anatomical abnormalities, followed by physiological discord.” The osteopath deals more correctly with the intimate chemistry of the human body in the treatment and cure of disease than does the medical man. Correcting structure corrects cell-chemistry, and thus corrects function, which is always the end result of cell chemistry. Dealing as it does with the physics of the human machine, osteopathy restores normal balance to its workings, puts it in fit condition to provide freely all the chemical substances necessary to its health. Therefore, when it comes to the question -of chemistry, the osteopath is a better drug doctor than the “�drug doctor” himself. In further pursuit of a clear understanding, let us consider a few of the things we do. Osteopathic treatment has repeatedly corrected pathological states of kidney, allowing an applicant, previously rejected, to be accepted for life insurance. In numerous cases of hypochlorydia and hyperchlorydia, the chemical unbalance of stomach secretions has been shown by test to have been corrected. In ty- phoid fever, osteopathic treatment changes the temperature chart and alters the reaction of the blood and urine to the Widal and Diazo tests. Osteopathic treatment has caused lacking ear wax and lacking perspiration to be secreted ; it has caused hair to grow, running ears to heal, birthmarks to disappear, and so on. Only through correcting cell chemistry could such results be achieved. Let us consider definitely just how we do what we do.. Let us attempt to gain an intimate idea of just what results of this kind mean, biophysically and biochemically considered. We say that we correct the lesion, thus correcting nerve and blood supply, thereby normalizing structure and function. Of course, correcting nerve and blood supply is only the first step, and the after care and attention to a case is (not always but often) just as important as after any other surgical operation.’ In correcting nerve and blood supply we aim through them to correct and regulate the whole of the internal workings of the body; that is, by adjustive treatment we correct the biophysics, and by correcting biophysics we correct biochemics-the whole of the intimate chemistry of the body; for we thereby, as an end result, normalize all such things as internal secretions, endocrines, ferments, enzymes, hormones, chemotactic substances, electrical reactions of cations and ions, etc. It could not be otherwise, and we should fully realize all the far reaching implications of the dosage we administer under the name of an osteopathic treatment. We should realize that the mechanics, physics, and chemics of each of the billions of body cells are all directly influenced by our work. I now call to your attention the subject of edema. We meet it frequently; in many cases we relieve it promptly by our osteopathic measures. We know that often a few minutes treatment will quite remove the edematous swelling from a tissue. Considering edema biochemically and biophysically, we find it to be due to a disturbance of the forces which control the direction and flow of fluids through the body membranes. These are: diffusion pressure ; hydrostatic pressure, i. e., capillary blood pressure; osmotic pressure of blood proteins ; and differences in electrical potential.. It has been shown that the capillary wall may vary from time to time in its permeability towards proteins, and that the cell wall may show a selective permeability towards ions which are of equal diffusibility. There also enters a difference in the electrical potential of the ions. The correlation of the four factors just mentioned for the purpose of maintaining the water balance of body tissues is effectively maintained through the nervous system, some believing in the existence of a nervous system, some believing in the existence of a nervous control center in the hypothalmus, although hormone control also plays a part. It is also shown that electrical currents are produced in the body during muscular, nervous and glandular activity. In the case of the edemas which we correct, we do, by opening up drainages and circulations, by bringing to the part fresh blood circulation and nerve tone, control the various diffusion, hydrostatic, and osmotic pressures involved, and also no doubt the electrical potentials. Furthermore, it is obvious that we do this even to the extent elf alter- All Rights Reserved American Academy of Osteopathy® 65 SYMPOSIUM ON THE ART OF PRACTICE ing the very permeability of the capillary walls and of the cell walls themselves. We have among us expressions that state that if a man is fat he is bloated and full of poison. It is quite true that many an apparently adipose individual is suffering from a waterlogged and toxic state of the general body tissues. In many such cases, as well as in many other kinds of cases, “acid retarded ductless glands” are responsible for the widespread endocrine unbalance which works havoc within the system. Research at the A. T. Still Research Institute �has shown that when osseous lesion is artificially produced the tissues about the lesioned area become edematous and the reaction of the tissue fluids concerned become acid. The same must be true of tissue lesions, no matter how produced. Let us consider, therefore, the train of pathological events thus started. Lesion produces edema and local acidosis ensues. Now, physiological, experimentation has shown that a weak acid tends to short circuit the vasomotor nerves. Such being the case the blood supply to the involved area is at once affected and congestions ensue. But as soon as the blood supply is altered the tissue metabolism is altered. When the cell metabolism is altered the cell chemistry is altered. The occurrence of edema means that the very permeability of the cell wall and of the vessel wall is alter&d. Furthermore, the electriCa reaction of the ions must also be altered, and this change in the electrical potential must also affect that quality of selective permeability shown by the cell wall towards ions most needed and desired by it for its integrity of tissue and function. Where then could a limit be fixed beyond which, in the production of dysfunction and disease, this pathological trail might not lead? Any sluggish tissue is per se acidosed; that is, its hydrogen ion concentration has been changed. In this sense any stagnant tissue fluid or other fluid of the body tends to become acidly toxic. It is readily seen, to go a step further, that any �tensed or congested tissue is in a similar state. This is so because any sluggish area of tissue or of fluid is being underoxidized. Such sluggishness effectively prevents to a greater or lesser degree the free ingress of the blood, �the hemoglobin of the red cells of which is loaded with the oxygen it has absorbed from the air in the lung vesicles. Therefore, the CO,, the carbonic acid waste, accumulated in the tissues and awaiting cartage back to the lung via the red cells, is not properly evacuated. The fluids and tissues involved, therefore, tend at once to become acidly toxic, and the whole pathological train just outlined is initiated. To take a step further: it becomes at once apparent that any degree of anoxemia, no matter how slight or how produced, tends to produce such status of acid toxicity. Thus originate the small beginnings of death. Another angle of the proposition may be considered: Take the tissue tensions which more or less we encounter in practically any human body we touch. A tension in tissue, readily felt under the examining fingers, is a congested tissue, with all the potentialities of congestions and sluggish tissue outlined heretofore. But a tissue tension which, by the way, keeps itself going, feeds itself, tends to increase, never actually lets up entirely day or night, must have some reason for its being. What is it that keeps a tensioned tissue tense? We may not know, entirely. Factors just mentioned certainly enter into the situation. But whatever its ultimate cause, certainly it does require some sort of energy to keep it up. Therefore I feel safe in saying that tissue tension is a source of nerve leakage. It is always using up “current.” It is like burning the electric light all night. It is a source of unjustified demand upon tissue, which tends in the long run to lower it, to devitalize it, and to make it a weak spot which is a danger spot. This phase is, of course, quite apart from the mechanistic features of tissue tensions which constitute lesions either primary or secondary. Thus do tensions and toxins take their toll; thus do men become literally embalmed in their own poisons-stewed in their own juices. If in what I have had to say I have succeeded in presenting to your minds a clearer picture of what conditions and forces we deal with when we deal with the human body in disease, it may assist you in your efforts for the alleviation of human suffering.

(Condensed) Some eight years ago, I reported to the Eastern States Osteopathic association, at its meeting in Atlantic City the cure of a desperate case of infantile convulsions in a threemonths-old babe. I wish now to recapitulate briefly that report, and to supplement It in introducing my remarks upon the subject upon which I am to speak. This was a case of forceps delivery, the child’s skull being badly misshapen by the forceps. After a few weeks in which it appeared to be normal, the child gradually over a period of some two months, developed a condition darked by wry-neck, cross-eye, oscillation of eyeballs, spasm of the spinal muscles, and severe convulsions. The convulsions were eventually extremely severe. I n two weeks’ time, one hundred and ninety convulsions oc- curred. As many as twenty occurred in twenty-four hours Keeping the child under morphine did not control them Death was imminent as a result, and at this stage, osteopath; was used as a last resort. A prominent and anomalous feature of the case was the occurrence of a marked periodic bulging of the fontanelles and the parietal bones, the swelling out or “ballooning” of them coming on and subsiding at irregular intervals. None of the physicians seeing the case could understand this feature. Lumbar puncture had been,performed twice, but with the production of no cerebrospinal fluid, only a little blood. Then a little cerebrospinal fluid was withdrawn from the subarachnoid space beneath a fontanelle, giving a few moments temporary relief, and affording fluid for pathological test, which was negative, My own procedure at first was to give a light relaxing treatment of the spine and neck (with much trepidation, as the child might die at any moment) together with the caref$ though easily accomplished, reduction of a slight subluxatlon of the axis to the right.

For example, one may say that any stagnated body tissue, is, per se, an acidized tissue. This must be so because stagnation implies a failure of the normal circulation of tissue fluids. That is to say, the blood is not continuallv bringing to that tissue its freshening supply of oxygen, nor rem&&g from it its CO,, or carbonic acid waste. It is, therefore, acidotic and toxic. Moreover, it has been shown that a weak acid in the tissues shortcircuits the vasomotors. Such being the case, we begin to have an instant change in the tissue metabolism. The whole circuit slows, blood- and nerve supply alter, tissue-status changes, disease ensues. Hence we happen upon the express i o n - “ acid-clogged ductless glands” with its broad implication of endocrine damage and unbalance throughout the body. Consequently, it is clear to our fraternity that the very numerous measures at the command of the capable osteopathic physician applicable to the control of cerebral circulation (some of which I shall demonstrate at the proper time) may be so used as to profoundly affect intracranial pressures, production and circulation of the cerebrospinal fluid and the circulation to and nutrition of the cerebral cortex.

Vol. 32, No. 7 March, 1933 Essay on Vertebral Lesions E. G U Y, D . O . Mount Vernon, N. Y. A LBERT CAVEANT LECTORES Our editor is adamant on the propriety of prefacing an article with an introduction, of defining the caption and of defining the scope; therefore, ho! for a brief exordium to the four parts of these quixotic ramblings. There still lingers in my memory the favorite saying of an old teacher when imposing a just pensum: qui semel scripsit septem legit, and I found its application always valuable; this article may then be considered as an assemblage of personal notes intended originally for the purpose of better fixing the writer’s attention, step by step, upon various aspects of the problem of the lesion, which ceaselessly confronts the osteopathic practitioner. Broadly, any structural derangement which interferes with normal function may be, for convenience, considered as a lesion. If it can be detected by our methods of examination and palpation, and furthermore, is amenable to reduction by means of osteopathic manipulation, it might be called an osteopathic lesion but for the fact that the term is more than ambiguous, has an element of bumptiousness, and considerably narrows the field of operation. Effectively, as practice amply shows, there are a great many forms of local disorders, distant from the spine, which are not amenable to local treatment, but which, however, are found reducible through appropriate manipulations of the vertebral organ. To such as those, that term would certainly not apply. Besides, away from “Main Street,” in foreign lands for instance, osteopathy is at once taken at its face value, that is, bone disease and, by extension, a system of bone disease treatment; a fortiori, the expression osteopathic lesion is evidently not adaptable to requirements urbis et orbis. From the pompous caption, Essay on Vertebral Lesions, the readers must not expect to find herein a plethoric census of pedigreed and mongrel lesions observable in their vertebral habitat; instead, they will quickly be made to realize, to their dismay perhaps, the vengeful intent of the writer to expose again the deplorable dearth of knowledge extant anent the topography of that habitat. It is obvious that the lesion cannot successfully be tracked down to its lair if the hunter is but superficially acquainted with the labyrinthine passes and other peculiarities of the region. It will be indicated, however, that the understanding of the detailed structure of a vertebral unit will suffice to secure that of the whole vertebral column; and then, with the normal tissues well in hand, the detection of functional topographic derangements will be much facilitated. It is advisable to bear constantly in mind that there is no such thing as a single lesion; it is a material impossibility, since every single part of the body is dependent upon others for its existence, and that any disorder affecting it must necessarily affect not only vicinal but also distant parts. Since an apparently single local disorder involves at once a multiplicity of lesions, and that furthermore, the involvement may assume numberless aspects, census taking would be an impossible task. PART I EXONUCLEAR LESIONS In some of the earlier anatomy texts may be seen illustrations of the sagittal sections of vertebrae and articular discs, in which irregular extensions of the basement cartilage are located within the cancellous tissue of the bones. Then the conventional biconvex form of the disc is somewhat altered and there are depressions present in the floor at the roots of the extensions. It seems as if some of the cartilage had been extruded by pressure from within the disc. Poirier mentions extensions of the nucleus pulposus into the bones and also through the posterior layers of the annulus fibrosus, reaching close to the periphery. In the bone the nuclear substance is sheathed by cartilaginous tissue, soft within, but showing gradual ossifi’ cation without. Some extensions are filiform, some cavitary, and others are fissural. These fortuitous observations open up a vast field of practical considerations. Normally, tiny apertures exist on the inner surface of the basement cartilage, which seem a little larger in the region of the nucleus prober. The purpose served by those apertures is not, as far as we know, mentioned anywhere; possibly they are the terminals of some sort of canals located in the bones, through which exudate of nuclear substance is fed into the disc; this appears quite plausible, but it remains to be proven through careful and appropriate study, as the subject is important from many points of view. However, whatever may be the connections beyond the apertures, it is quite obvious that under ordinary circumstances there must exist means of preventing the extrusion of the nuclear substance, and then we are warranted in believing that these means are dependent upon the integrity of the circulation of body All Rights Reserved American Academy of Osteopathy® 69 70 ESSAY ON VERTEBRAL LESIONS-GUY fluids. Should this fail for some cause or other, so between the nodule and the nucleus. Depending of that a given aperture be left insufficient protection, course upon the amount and size of the extruded mass, then the nuclear substance could be forced to make its effects upon the contents of the vertebral canal its way insidiously outwards, sheathed in cartilaginous vary.

There lies all the difference between the artisan and the tinker. Citation of a case referred to us by an allopathic friend is deemed worthy of attention as regards gross symptoms, treatment and results. The patient, a young lady, was a constant sufferer from ambulatory hindrance-short steps, unsteady gait-coupled of course with a varying degree of dizziness; the acuity of vision of one eye was somewhat below normal, that of the other was gravely impaired ; there were menstrual disorders-irregularity, duration, profuseness, pains, general disturbances; the patient was stout, much inclined to obesity ; there were no evidences of blood disorders, and no record of infancy diseases. The upper dorsal region, particularly to the right, was very rigid, the lumbar very tender, and the cervical much involved. The case was very puzzling; however, it was evident from the response to the first three applications of osteopathic treatment that the gross vertebral column possessed structural integrity ; then, whence the disorders ? Under persistent questioning, the mother could not recollect any untoward accident, shock, fall, etc., but finally, most willing to help with any kind of clue, she stated that up to the eighth month her baby had been in most perfect health, then all of a sudden became affected in some obscure manner and thereafter did not develop normally ; the baby could not walk until past two years old. Evidently something had happened which seriously impeded normal development. Avoiding any form of prompting, it was finally brought to light that the baby had been cared for by a rather indifferent nurse, who one day in a moment of inattention allowed the child she was carrying on her arm, in a sitting position, to drop abruptly backwards, hanging by the knees. It was then remembered that PART II shortly afterwards the change in the child became apparent, but no one thought of connecting the seemingly ordinary incident with that change. We feel fully warranted in the belief that to the abrupt backward fall. of the child-being the one salient point in the whole history of the case-may be attributed the formation of a number of exonuclear lesions to which may be traced the origin and development of the disturbances affecting the patient. Under ordinary osteopathic treatment the menstrual disorders gave way totally, dizziness disappeared, walking became practically normal ; the ocular muscles functioned well and, according to the eye specialist now in charge of the case, vision in both eyes is making rapid and satisfactory progress. To some practitioners this tracing of etiology may seem fanciful; for us it was helpful because, sensing the integrity of the osseous structure, we bent our efforts upon the utmost activation of the circulation which, alone, could be depended on for the gradual reduction of the abnormal growths, or rather, of the pseudo tumors most probably existing in the vertebral canal. Two others, but rather extreme instances, might be cited, which could be held to prove that many �ills in after life may actually originate at birth. Both concerned babies less than one month when referred to us ; one had most severe torticollis, with of course the whole cervical region extremely involved ; the other could not take nourishment of any kind because of an intense constriction of the cardiac end of the esophagus produced by severe spinal lesions. These troubles were easily traced to remissness both during delivery and after. They were extraordinary cases, it is true, but common, daily observation suffices to make us realize the influence which the dangers incurred during the formative years of the individual may have upon the health and comfort of the grown-up. A.list of references will accompany the final article in the series. Essay on Vertebral Lesions SUGGESTIONS FOR A PROGRAM OF RESEARCH Normal function depends on the integrity and the mobility of parts. This is fundamental and, incidentally, is the osteopathic tenet. It immediately implies the possession of a most intimate knowledge both of the structure of the said parts and of their functions. The practice of osteopathy has fully demonstrated its worth, but the development of its theory, so urgently needed in view of the a d v a n c e of others, h a s n o t progressed very far beyond the dicta of A. T. Still. True, laboratory experiments have here and there amply verified the well founded basis of these dicta ; nevertheless there is lacking a well outlined continuity of impeccable demonstrations, as well as a far more advanced knowledge of the anatomy, histology and physiology of every component part of the spine than that which we have too complacently relied upon. Our mode of investigation must be patterned upon that of such men as-Claude Bernard and Ranvier, for example, if we wish to accomplish the desired results. Thus, before undertaking a given demonstration, we must have a clearly defined program of action; if we wish to study the effects of an artificially produced vertebral lesion upon a certain nerve, we must know in advance what tissues will be involved, the kind, degree and specific effect of that involvement upon the nerve itself as well as’ upon each of the correlated parts ; we must know precisely why the lesion, once formed, remains so, and what conditions obtain immediately after correction. It is therefore clear that physiological experimentation can proceed with as- surance only when fundamental knowledge of the parts dealt with is securely at hand; otherwise it will tread among so many complexities that it will fail to convince, even if seemingly successful. The needed information is not to be found in our anatomy textbooks; but there is ample evidence of a widespread desire for it, as shown by published accounts of investigations here and there pursued by practitioners of great ability. In the field of research concerning the intimate parts of the spine it was our heritage to lead; shall we be contented with merely joining? As a mere worker, it seems to me that some of the main subjects to which attention should be most diligently applied may be listed as follows: (1) the vertebral column viewed as an entity; (2) the vertebral unit, composed of two adjacent articulated vertebrae ; (3) the intervertebral disk; the annulus lamellosus ; the nucleus pulposus ; the exonuclear lesions’ (4) the intervertebral ligaments ; their innervai tion ; their control functions ; (5) the apophyseal articulations ; the mechanics of their displacements ; (6) the deep vertebral musculature; its innervation ; (7) the contents of the intervertebral foramen; (8) the nerve sinu vertebral ; its function as vasoregulator of the blood supply and drainage of the meningeal tissues and of others located in the vertebral canal and in the intervertebral foramina. (9) the supporting or connective tissue: i t s All Rights Reserved American Academy of Osteopathy® ESSAY ON VERTEBRAL LESIONS-GUY 73 The spine has always been viewed as a strut a column sustaining a vertical load increasing from the top to the base. The cervical region pyramided down to the base of the 7.C, then the column tapered down to about the 4.D., and thenceforth pyramided down to the base, that is the lumbosacral articulation. Made up of a succession of parts, or vertebrae united by very �strong fibrocartilaginous connections, the intervertebral disks, it formed a highly resisting,’ articulated assemblage which was considered as an organ of sustentation, capable of suppporting not only the weight of the body parts attached to it, but also heavy loads carried by the individual. As a whole it had, like a twig, flexibility in all directions, but to a degree varying according to region; it was capable of rotation and of circumduction ; and for each intervertebral articulation the same kind of motion had been carefully observed and recorded, although (according to Cruveilhier’s Descriptive Anatomy, 1852) their detection, is possible only through the study of the total displacements of the entire vertebral column. It seems therefore that the notion has persisted through all ages that, since man is essentially a biped, intended by nature for the erect station, it was necessary to conceive that means of maintenance of that station should be in the form of a sturdy pillar. What more natural then could it be than to endow the spinal structure with the attributes of the long bones of the limbs intended primarily as compression members ? This conception is now firmly rooted; our best textbooks dwell upon the attempts made. to determine mathematically the strength of the spinal column; to compare it to the relative strength of a straight column, or even of a single elastic arc, and of a structure made up of several arcs. They tell us that the conformation of the vertebral canal, together with the yellow ligament linings greatly add to the resistance of the spine, etc. The best proof advanced, which should preclude any further argument, is the very fact that the spine is pyramided downwards, so that the lumbosacral articulation offers the greatest area of, support, and consequently, cannot be otherwise than considered as the true base of a pillar, a column of sustentation. All these points are made in chapters devoted to articulations, which follow those dealing THE VERTEBRAL COLUMN IS NOT A PILLAR with the minute description of bones and ligaments.

G UY, P a r t MECHANICS OF THE VERTEBRAL UNIT The assemblage of the vertebrae and their connecting ligaments forms an inert structure devoid of the rigidity and of the elasticity commonly attributed to it in the living body. This assertion has been fairly proven, I think, by the considerations advanced in a previous part of this essay, which showed that in a totally relaxed body the spine is absolutely unable to sustain it in position, and also that a specimen spine, such as prepared by H. V. Halladay, was unable to sustain a. light weight applied at its upper end. Normally, the ligaments possess a certain amount of elasticity which checks them gradually at their limit of extension. They are pliant, fibrous bands whose main function is to maintain the union of the osseous parts of an articulation while allowing the fullest range of motion. They are provided with a system of innervation, the terminals of which are capable, in a manner still obscure, of sensing the approach to dangerous extremes of motion and of setting up appropriate reflexes for safeguarding the integrity of the structure. Their nutrition and elimination processes must be like those of other tissues, under the control of vasomotor innervation. Separated from the body they gradually acquire an extraordinary degree of �hardness which, as experienced in the dissection laboratory, is probably responsible for the lasting impression that the spine is really a very rigid organ of sustentation. Their pliability may be appreciably restored through prolonged immersion in a fluid preparation, the main ingredient of which is neat’s-foot oil. If the spine consisted solely of vertebrae united by intervertebral disks, such a structure would be totally inadequate in several respects : mechanically, for insuring accuracy of motion; and for the protection of highly specialized organs. Therefore nature has wisely provided for each intervertebral union two guides in the form of apophyseal �articulations; in each of these a process extends from the junction of the lamina and pedicle of the vertebra above, and terminates as a facet engaging in smooth and constant contact a similar facet extending in the same manner from the vertebra below. The structural details are fairly well known, and we had occasion to I I I deal with them before in “Vertebral Mechanics.“* A very pliant capsule encloses each articulation, thus providing both protection and lubrication to the contact surfaces. Special emphasis is placed purposely on guides and constant contact because these are factors of the utmost importance in the present analysis. Effectively, if we assume that the contact is intended to be constant (and we have every reason to do so), it follows that any displacement of one vertebra relatively to the other must be directed in accordance with the geometrical contour of the guiding surfaces. The orientation of these differ according to the region of the spine considered, and it changes abruptly in passing from one to the other of the three recognized regions, the cervical, the thoracic and the lumbar, but the principle involved obtains for all. In the normal, living body, all the ligaments concerned in the union of two adjacent vertebrae, constituting one vertebral unit, are entirely inadequate, not only to insure the necessary working contact, but also to guard against the separation of the apophyseal surfaces. This separation may be effected in two ways: normally, through the action of two opposed forces pulling the facets apart; and through slightly oblique pull, opening the articulation in hinge-like fashion. �Throughout our most strenuous exertions, our most violent efforts, the whole body is ever watchful, jealously protecting the entire spine against any local disarticulation. It is evident that, with the body tensed in action, a forced apophyseal separation would entrain a sudden axial disalignment of the vertebrae involved, uncheckable in time to prevent most serious injury to the cord, to the roots, to the blood vessels, the ganglionic chains and other organs attached to the spinal structure. Such occurrences are unfortunately very frequent, as in falls, shocks, blows and brutal sports, and often result in persistent lesions and disabilities. In the daily application of the osteopathic technic it is currently found necessary’ to produce “Guy. Albert E.: Vertebral Mechanics, JO U R. AM. 1930, Aug.. Sept. All Rights Reserved77 American Academy of Osteopathy® O S T E O. AS S N ., 78 ESSAY ON VERTEBRAL LESIONS-GUY apophyseal separation for the specific purpose of normalizing the position of one vertebra with respect to the adjacent ones. This is always done judiciously after due manipulatory preparation of the vicinal tissues. Originally intended for just such a purpose, this practice soon had to be extended to other parts of the spine, because to one well defined lesion always corresponds at least one other, as a compensatory’ one, and most usually a series of others. Then it was found beneficial to proceed further in some cases, and thoroughly to loosen up the whole spine. Incidentally this form of manipulation proved useful in demonstrating the extent of freedom and mobility of the spinal articulations. Although the precise occurrence of an intentional separation is readily sensed by the operating hands, and the patient does not feel incommoded thereby, it is accompanied by a certain factor, ominous and somewhat disconcerting to the subject, in the form of a cracking noise which, however, may be attenuated almost to the vanishing point through appropriate technic. This novel form of treatment which, when needed, involves the direct and precise manipulation of the vertebra, was combated from the beginning by adherents of other schools, who could not, and cannot even today, admit either the feasibility of disjointing the articulations without causing irreparable damage to the body, or the demonstrated beneficial results of osteopathic manipulations. It is difficult to reconcile this attitude of absolute negation with the statements printed in recognized standard books. Thus we find in the latest edition of Poirier’s Anatomy, Arthrology section, page 62, that “the apophyseal movements are essentially gliding and rocking. Because of the laxity of the capsule they are but partially controlled by the configuration of the articular surfaces. In gliding the surfaces slide upon one another in all directions; in rocking they remain in contact at one of their extremities, but separate at the other, and the articulation stands gapping. . . . ” It seems impossible to imagine a grosser misconception of the subject, yet similar citations from recognized authorities could be given here, the mere reading of which would leave us like the above articulation, gaping. But before we start on a career of lapidation at long range let us be on guard against boomerang effects, and save some of our pebbles for vicinal targets; for we have on our own shelves some works dealing with the matter of the vertebral lesion, masterfully attributing it to the hooking of the edge of one articular facet into the surface of the corresponding one: thus forming an ingenious structure akin to the druidic dolmen of past ages. A late addition to these is an opus on anatomy, unfortunately illiterate in redaction, which again upholds such a contention. And so we stand in dismay, confronted by a divergence of understanding of a point of basic, vital importance ; on the one hand we find most positive assertion to the effect that the spine is a closely knitted entity, susceptible of flexural mobility, while on the other we are told that, in an important aspect of that mobility, in rocking, every one of the twenty-three spinal pairs of apophyseal articulations ceaselessly works through a series of gapping contacts. If this were true how could we account for the cracking noise coincident with the intentional separation of the joints? Or again, would not any movement of the spine be accompanied by series of creaks? An analytical comparison would be a waste of time, for it is evident that on both sides the notion of function as the controlling factor received but the scantiest of attention. And yet, with it as a guide the difficulties of the problem are reduced to a study of the intimate details of the structure involved. We may then proceed tentatively as follows: (a) the vertebra: must be firmly united in a manner that will permit flexural displacement, hence the intervertebral articulation with its strong cartilaginous and ligamentous attachments, forming also a wonderful cushion capable of instant adjustment to any oscillation of the bones ; (b) vertebral motion must be precisely guided, and specially important organs safeguarded, hence the apophyseal guiding articulations ; (c) these articulations must comprise two elements, one being the necessarily guiding structure proper, is provided by the articular facets working in smooth contact; the other is the means of constantly maintaining this contact, and we should particularly note that its conception as such has never, to the writer’s knowledge, been described before ; (d) besides a vascular system there must be another, nervous, to preside over the needs of the tissues, to warn of the approach to danger limit of displacement and to guard against the disruption of contact between articular facets. We have studied before the motions of the apophyseal articulations, and indicated a method of determining the centers and axes of oscillation, but these questions will be, further on, given additional and perhaps more convincing’ attention. It is clear that in normal activity the vertebral ligaments may be considered as very strong pliant bands, possessing a certain amount of elasticity ; some of them, the yellow ligaments, are more elastic than the others because of the muscle fibers in their structure. (This is true according to such anatomists as Poirier and Testut.) But if we reason that the separation of the articular facets is produced by an effort of extension applied to a region of the spine situated above one given vertebra held fixedly by the hand, as a fulcrum (as is the case for all dorsal vertebrae), we realize that all the ligaments are of very little help in resisting the disruption of contact. By operating in this manner we may, according to our ability and strength, disrupt both contacts at once, or only one at a time, but then, if the separations are effected separately we have, perhaps unconsciously, employed a method based on a different principle, which is used specially for the cervical and lumbar regions. Thus, instead of selecting one whole vertebra as a fulcrum, we make a fulcrum of one apophyseal articulation, twist the spine and separate the other articulation. This method is general and is applied to all parts of the spine by many most skillful operators. However it is accomplished, the stages of the operation are always the same: (1) preparation of the tissues; (2) positioning; (3) sensing of thorough relaxation ; (4) separation of the articulation ; (5) immediate reflex closing of the gap with coincident cracking noise ; (6) digital verification of the normal adjustment of the articulation ; (7) final manipulation of the vicinal tissues. When effecting the separation one is conscious of a strong, deeply seated resistance which, with an initiated and thoroughly relaxed patient, may be Guy, Albert E.: Vertebral Mechanics, JO U R. AM .

Sketch showing muscles in vertebral grooves. will be forced beyond the extreme range of motion, with consequent injury to the various tissues of the attachments, of nearby structures and organs. With a bilateral involvement the vertebra may return to its neutral position, while with one more severe on one side than on the other, the vertebra will return partially, and then be maintained in a strained condition of combined twist and flexion. At first there is always inflammation and pain ; later on, due to the reorganization of the injured tissues, there may remain a certain degree of functional impairment of the articulations. We may also consider as major lesions in the upper dorsal region those evidencing persistent characteristics, responding sluggishly to treatment. A large percentage of these disorders is found in women; they are mainly of costogenic origin, with active foci mostly about the right sternal aspect of the ribs, and abnormal approximations of the ribs in the axillary region. Bearing this in mind, appropriate treatment may be devised, to which the two kinds of disorder will be found amenable. Traumatopathic lesions require special consideration, if meant to designate those in which the articulations failed to return to some position within the normal range of motion, because then we have to deal with conditions of altered structures. Analytic study would perforce be largely conjectural for any given case, and we must be contented with the proofs of daily experience that such lesions are well responsive to osteopathic treatment. We propose here to demonstrate diagrammatically that one given vertebra may be maintained in deviation, that is, in lesion, with its articular facets in extremes of displacement, yet in working contact with the corresponding ones, instead of being held in separation, or hooked on to one another, as unfortunately imagined by some writers. We would like first, to emphasize the point that wherever found, either on fresh specimens, on dry prepared spines, or on spines practically spoiled through prolonged inhumation in damp soil, the articular surfaces present a smooth and unctuous area of contact; in articulations long immobilized by exostosis of the edges, the areas are found practically unimpaired after the osseous growths are cut away. This good condition could not be expected to obtain if the surfaces had been maintained in separation, as in complete dislocation, in the living body, for then there would be great possibility of osseous alteration. Even in skeletons of hunchback bodies we have observed the normal state of the surfaces. All these remarks confirm our contention that the articular facets are kept constantly in working contact through some powerful means, which must be specifically intended for that-purpose, and which is the diversified action of the deep muscular mass nestled in the vertebral grooves. In constructing the annexed diagram (Fig. 2) purporting to represent the assemblage of a number Fig. 2. Diagram showing vertebral lesion. All Rights Reserved American Academy of Osteopathy® ESSAY ON VERTEBRAL LESIONS-GUY of vertebrae, similar in size and shape, the vertebral axis is assumed as a straight line ; the posterior contour line would likewise be straight for normal conditions, and the centers of oscillation be located on a straight axis. This is to simplify the demonstration ; it will become obvious later that by using the measurements taken from an actual spine a construction can be drawn which will lead to the same results and conclusions as with the present one. The center of oscillation is not that of the nucleus pulposus; its position was determined from measurement on the llth D. of a spine just at hand ; the radius of curvature was found to be a little over 1½ inches, with the distance between centers about one inch. The curvature of the two upper facets corresponded practically to that of a spherical surface, so that there was only one center of oscillation, which permitted perfect circumduction. In some vertebra there may be one curvature, anteroposterior and another transversal, so then in studying the kinetics of two assembled vertebra! two axes of oscillation must be considered, as explained in “Vertebral Mechanics” (THE J OURNAL , July, 1930). Each vertebra is shown in templet form resembling somewhat the lateral aspect of a “low back chair,” the. front foot of which terminating as a ball is received in a socket carried by the templet next below; on top of the foreleg is a similar socket receiving the ball foot of the templet above. The socket is a guide bearing allowing the free circumduction of the leg; however, it is shown elongated to the right, merely to indicate accommodation to anteroposterior displacement to suit apophyseal separation. The upper and transverse part of the templet ends, at the right, as a guide process, the contour line of which is the generatrix of the spherical surface containing the facet areas of the real articular processes of the vertebra. The whole construction rests then upon the principle that the facets, in this instance spherical segments, are the true fixed guides for the motion of the vertebra above, and that their contour line is an arc of a circle. It follows that the motion must take place about the center of that arc, which then becomes established also as a fixed point, whose position is easily determined by elementary geometry, but which, having no material entity as a pivot, is in reality a virtual center of oscillation. The templet terminates downwards at the right as a guided process intended to represent one of the lower articular processes of the vertebra, and it is shaped so as to conform exactly with the contour of the guide process of the vertebra below. The ensemble of one guide and one guided process constitutes an apophyseal articulation; the working surfaces are kept constantly in contact by the resultant pressure from deep muscle mass action. A certain range of angular displacement is indicated, having a neutral position, an extreme in flexion and an extreme in extension. It is clear that intentional separation may be effected by selecting one vertebra, resting it posteriorly against a fulcrum, and exerting a thrust on the vertebra above in the direction of the neutral position axis shown at the lower end of the diagram. No matter how this is done it is almost certain to be gradual, beginning at the upper end of the, guide process, and then extending instantly throughout the contact area. To the experienced and careful observer it appears as if, for once, the vigilant muscles having been caught off their guard, either through very swift action, or through cautelous slow proceedings, had suddenly 81 realized their unwarrantable laxness and then, with lightning speed, slammed back the guided process in contact with the guiding surface, which fully and satisfactorily accounts for the pop or cracking noise. Furthermore, the muscles seem to have doubled the patrol, since in a normal subject it is not possible to produce another separation at the same point until after a lapse of several hours, sometimes until the next day. In a subsequent article attention will be given to the effects of the separation, which may be beneficent when the latter is normal, and highly detrimental when produced by unskilled and forceful exertions. We are now facing a most terrible situation, for we have shamelessly omitted to take the famous nucleus pulposus into consideration as the all important factor of the intervertebral articulation. Unlike some others we wish to remain unbiased in this respect, and feel amply justified in adopting the notion that the guiding surface is the prime factor to which all the other parts of the articulation are subjugated. The nucleus remains the wonderful cushion, essentially and instantly adjustable to all the normal displacements of one vertebra relatively to the adjacent one, but for us it is not the ball bearing element of the ancients and of Monro, of Morris, etc., etc.; its center proper does not exist, and if it did it could not have the fixity of position of our virtiual axis of oscillation. Let the diagram represent a sagittal section of part of the spine, in which the lower vertebrae and the top one are in normal position and alignment; the three others are involved in posteroanterior deviation; the lower one of these is in extreme flexion with respect to the one normal below ; the second is in extreme extension with the first ; the third is in extreme extension with the second and in extreme flexion with the normal vertebra above. We have then a condition frequently observed in practice, in which one vertebra is fixedly held in anterior displacement. By applying the same method another diagram may be constructed, in which the vertebra would be shown in posterior displacement. Likewise we can draw a figure showing lateral displacement to the right or to the left, and then, with a little more labor the vertebra may be placed in simple rotation, or again, in a position involving the three kinds of displacements, sagittal, transverse and rotative. Thus we may picture any one of the varieties of vertebral lesions commonly known, and in each case the apophyseal articulations would remain in normal apposition even at extremes of the range of motiotin Q.E.D. If the diagram had been made to represent an exact sagittal section of an actual spine the deformation would be seen more pronounced, due to the curvature of the column. The sketch shown here would concern conditions obtaining in the dorsal region, whereas for the cervical and the lumbar other constructions would be required, because the oscillation axes are differently located and there are two main axes usually involved for each articulation. However, the delineation presents no special difficulties for any one keenly interested in the subject, but it must be predicated upon the notion that articular facets are normally maintained in contact through muscular action, and that when separation is intentionally produced the contact is instantly and noisily restored. Now the question arises : when a vertebra is positively found out of alignment, either through visual All Rights Reserved American Academy of Osteopathy® a2 OSTEOPATHIC PATHOLOGY OF SPINAL MUSCLES-BURNS observation, palpation or radiographic representation, what maintains it in abnormal position? With a lesion of long standing the ligamentous attachments must have become adjusted to the abnormal conditions, but even with alteration in their length and pliant qualities, they could not be accepted as the main maintenance factors, except perhaps in extreme cases of spinal deformation. The main factor is the permanent contracture of the muscular mass nestled within each of the vertebral grooves. The production of the lesion is due to exaggerated action developed by that muscular mass or by parts of it; while the causation of it is abnormal and disordered stimulation of sensory nerve terminals, conveyed to the central system, and thence reflected in the form of abnormal motor impulses to the muscle cells. Although the muscular masses are symmetrically disposed, so that a strand in one has its antagonist partner in the other, it does not follow that action is always coordinated; instead, we find that a spot on one side may be so tensed as to cause tilting, or rotation, or a combination of both, affecting some osseous part, while the corresponding spot on the other side remains practically relaxed. We have ample evidence of the existence of local muscular disorder with every patient in our daily practice, in the symptomatic form of tenderness revealed to the patient through deep palpation of the groove muscles. In some cases the deep muscles may remain for a time in a condition of excessive contraction and in perfect coordination of action ; the whole, a certain length of the vertebral column is then in a state of intense axial compression. Relaxation may take place spontaneously, though gradually, or may result from some form of treatment ; but it may also happen that a slight exertion will cause a sudden disruption of equilibrium of the structure, accompanied by excruciating pain felt in some region of the spine; this occurs frequently in the incipient stage of lumbago. This is in accord with the laws governing the flexural buckling of beams and columns, of any shape, all of which have a definite limit of stability under load. See “Flexure of Beams,” by A. E. Guy, Van Nostrand, N. Y., 1903. Such buckling occurs also in torsional efforts. Now that the possibility of the maintenance of vertebra: in deviation has been demonstrated we can understand the gradual deformation of the vertebral column in scoliotic and kyphotic cases; as it seems obvious that in the formative period the osseous structure, being kept deviated �at various points through the incessant pull of the contractured deep muscles, must necessarily undergo extraordinary changes in shape. The next article will deal with the properties of the fibrous tissues (tendons, ligaments, connective tissue, etc.) ; their innervation, vascularization and sensibility, in reference to the vertebral lesions.

Osteopathic palpation discloses muscular tenseness and tenderness in the cervical, dorsal and lumbar regions, affecting particularly the deep-seated tissues ; and often vertebral lesions are found, which interfere with the general mobility of the articulations. It is unnecessary to reproduce herein detail matters that may be found in many books on diagnosis and with which the reader is well acquainted. However, two quotations from Sajous’s Analytic Cyclopedia of Practical Medicine cannot fail to interest our practitioners, and besides, they fit very well in the framework of this essay. Thus, on page 325 in volume 1, on the subject of acute rhinitis, we have this about the exciting causes: “Although certain depraved conditions of the body may be said to predispose to attacks of acute rhinitis,’ usually there are certain causes to which the attack may be definitely attributed. Exposure to cold and wet when the body is overheated; exposure to sudden or extreme changes in the atmosphere; the wetting of the feet when the system is debilitated from other diseases; or the chilling of the body from any cause, especially as to allow a draft of air t o strike the back of the neck or head. This seems to support theory, advanced by some that the i m - of action, constriction or dilatation of the vessels, the nervous system governs all the chemical phenomena of the organism. . . .” In his celebrated “Lessons on Toxic and Medicamental Substances” Claude Bernard studies at great length the effects of curare and strychnine; the first of which paralyzes the motor nerves without affecting the sensory system; the second does the contrary. He found that in either case neither the nerve fibers nor the muscle cells were affected to the extent of losing their property of response to galvanic stimulation; the same thing obtained also for the spinal cord. The effects of the poisons centered then upon the nerve terminals proper, but the exact modality of the paralyzing action remains to this day undisclosed All of these findings were amply confirmed by the extensive researches of such men as Brown-Sequard and Vul: pian. For our purpose perhaps the most important points are-first, the proven fact of the independence of action of any given motor nerve which, when isolated while the rest of the organism is under the influence of the poison, may perform its regular function when suitably stimulated; and second, the proven fact that the lesion of one posterior root is transmitted by the cord to all the other roots, so that the effects of a poison acting upon the peripheral part of the sensory pression of cold on certain parts of the body produces system, once reaching the cord, are transmitted to all an inhibitory effect upon the vasomotor nerves con- the motor nerves.

It was observed on laboratory animals as well as on the cadaver that in many cases of nervous disorders the effects of hyperemia or of ischemia centered mainly upon the gray substance of the cord, which it is held, goes far towards explaining general vasomotor as well as muscular disturbances in distant parts of the body. That, of course, concerns acute cases, with well developed morbid conditions ; however, �even in benign cases, it teaches us that one of the disturbing effects of the abnormal impression transmitted through the sensory path is possible interference with the function of the cells in the cord, such as to delay the return to normal of the reflexively affected parts. Reverting to the common cold we may try to solve the problem of the development of a mild case of rhinitis, with profuse watery discharge, brought about after removal of rubber shoes, worn during a brisk walk in rainy or snowy weather. Just before that removal the feet felt warm but moist ; immediately after there was a chilly sensation, and with a cold ground draft on a concrete floor, all the necessary disturbing elements were present, particularly so, if the person remained inactive for a considerable period of time. The most apparent symptom to the observer is the profuse flow; it has been well investigated by Ch. Robin in his Treatise on Humors; its composition varies with the stage of the disease, but generally speaking, it is made up of exuded and secreted fluids, all of which are of course derived from the blood stream; the manner in which the transformation may take place is the key to the problem. Incidentally, the principle involved applies fundamentally to all normal processes of nutrition and upkeep of the body tissues. The second symptom is the turgescence of the nasal mucous membrane, from the surface of which the abnormal flow is given off. According to our premises, which illustrate but a common cold occurrence, the original disorder affected only the extremities and not at all directly any part �of the nasal region ; hence we have here a clear case of reflex action. The better to study it I prefer to submit here a graphic demonstration. Let us assume that the diagram in Figure 3 represents a cell, a gland, or more liberally, a very small region into which blood is at first fed through the arteriole at the left into capillaries at the bottom, and then after collecting the wastes passes out through the venule at the right. To suit the normal condition of the region a certain level must be maintained therein. We imagine that a delicate contact detector receives an impression which is transmitted to a motor cell or ganglion and thence relayed to the gray matter cells, from which one reflex is started which is transmitted to the sympathetic vasomotor regulator, causing a constriction of the arteriole walls, the mechanism of which is represented here in the shape of a valve, and the incoming supply is therefore reduced another reflex is simultaneously sent to the motor nerve regulator, causing the outlet valve to be opened more widely, which obviously, corresponds to some relaxation of the tonus of the muscular wall of the venule, that is to dilatation of that vessel, whence there is increased outflow. As a result of these combined actions the fluid content of the region is reduced and the level may be restored to normal. Should the level 85 Fig. 3. fall below the normal a reverse process automatically . functions through precisely the same mechanical elements. For a long time the sympathetic system was thought sufficient to regulate the circulation, through the simple reflex action of the sensory system ; effectively, inhibition of the sympathetics would cause relaxation of the vasotonus, hence vasodilatation ; whereas activation would cause increase in vasomuscular tonus, hence constriction. That would imply, of course, that inhibition, for instance, would cause simultaneous increase of the caliber of both the arteriole and the venule; obviously then in case of subnormal level, the inflow would be increased, but, as the outflow would be similarly augmented, the same volume of fluid would pass in and out, and the regional contents would remain subnormal. To make up the deficiency the inflow must increase and the outflow be checked. Vulpian and Ranvier pointed out the necessity of a mechanism of venous constriction ; and they insisted upon the fact that the musculature o the walls increases in inverse ratio to the caliber of the veins, in which they differ from the arteries, thus clearly evidencing a construction intended to fill a definite function. But the circulation is not intended solely for the immediate nutrition of the body tissues; it must also supply the various glands with sufficient quantity of blood from which they, in turn, take secretions essential for the performance of certain most important functions, salivary, gastric, enteric, etc.; and as the volume of these assume enormous proportions, we are compelled’ to recognize that the inflow into the’ region, or gland, of our diagram, must operate to the full caliber of the arteriole and actually produce an overflow from the region into the outer spaces. This is only possible, obviously, when the venule is sufficiently constricted; and if the sympathetics are inhibited to permit dilatation of the arteriole, some other agency must instigate the muscle contraction of the venule wall. The simple contact level detector still suffices when the gland is inactive, but it must be supplemented by some appropriate means, receptive to impressions issued from the sensorium or collected from nearby sensory terminal organs. The reflex is developed as before, with inhibition of the sympathetics and activation of vasoconstrictor nerves. The nasal mucous membrane contains a large number of glands; Sappey found 30 to 50 to the square centimeter. Besides, there are extensive venous plexuses, which increase in size from the outer surface towards Academy the basement layer, attaining their greatest All Rights Reserved American of Osteopathy® 86 ESSAY ON VERTEBRAL LESIONS-GUY proportions within the mucous membrane covering the very elastic.

Thus, are the cells merely distended by an absorption of fluid, so that not of hyperemic conditions within the mucous linings, but more properly, of an intense congestion followed the membrane becomes thicker and its various layers by a profuse exudation of fluid made up of mucous increased in area, so that the whole is in a state of and seromucous glandular secretions together with extraordinary tension which, at the limit, might lead watery serum derived from disordered diapedesis to overstretching and tearing of the constituent tissues, through the walls of the cavernous plexuses.

Experimenting on this patient showed that intentionally provoked tetanic extension could always be reduced by forceful flexing of the toe. This observation was of great value to Brown-Sequard, and he made use of it in the study of a number of cases of epilepsy and hysteria. His published reports were found in agreement with those of a number of other physicians interested in nervous diseases, and it became generally recognized that, not only on human beings but on laboratory animals, sudden, forceful, and at times, violent exertions upon the muscles first affected in the epileptic attacks, or in cases of cramps and clonic convulsions, succeeded in abating the crises, and often in aborting the attacks. Such empiric results demanded logical explanation, lest medical practitioners were taxed with charlatanism, and that which won general approbation is (a) that there exist at the base of the encephalon, or along the cord, abnormal conditions capable of provoking reflexes causative of the epileptic attacks; (b) that forceful impression upon the terminals of centripetal nerves is referred to the nervous center commanding the mechanism of the attack ; (c) and 89 that there is then inhibition of the activity of the elements concerned in that morbid command. That the intentional apophyseal separation, as practiced osteopathically, is beneficient in overcoming the contractures of the deep muscles and thus permitting the reduction of vertebral lesions, and furthermore in suractivating the general circulation, is amply proven, not only by the sensation of well being, of relief, felt instantly by the patient, but also by the after effects. That the principle involved is also based upon well proven and most logical considerations is evident from the fact that these were first established by men of sound learning, and recognized among the greatest authorities in the medical world. Perusing and meditating over the old texts is earnestly commended to those of our profession ; their belief in the principles to which they devoted themselves is bound thereby to be more firmly assured ; they will realize that there is more to osteopathy than has yet been taught to them; and that it is capable of accomplishing far more by itself than when burdened with too lightly considered adjuncts. To our detractors, if ever sincere, review, or perhaps discovery, of those old texts, is also commended.

The flexibility of the column as a whole is too obvious to be in question; the overwhelming importance of the mobility of its individual articulations is not understood outside the realm of osteopathy. Luxations are recognized and treated, the term being merely synonymous with dislocations, meaning condition of a bone out of its normal position or articulation. Subluxations are partial or incomplete dislocations. Those two always imply evident gross pathologic disorder. The osteopathic lesion, with its far reaching influence, is a concept difficult of acceptance by pathologists at large, and is generally considered as beneath attention through professional antagonism, although extremely serious attempts have been made at various times and places to involve it, under another name of course, as causative of well observed disorders. The view of anatomists towards the spine as an articulated organ may well be represented by the following typical statement translated from the most recent edition of an anatomical treatise widely known and copied: “The dominant characteristic of the spine is not its mobility. Nature has lavishly provided all that could contribute towards its consolidation. In multiplying the vertebra, it has so enmeshed them together that they tend to immobilize themselves in solidarity for action . . .” The view of the pathologist anent the mobility of vertebral articulations was rather forcibly expressed not long ago to the writer by a leading professor of a great medical university who, witnessing for the first time the osteopathic correction of some cervical lesions threw up his arms and unleashed an unexpected extensive vocabulary, the meaning of it all, when boiled down, was that he considered it a murderous act to attempt manipulation of the vertebrae, because the consequent displacements would bring pressure directly upon the cord, with death rapidly ensuing.

ALBERT E. G UY, D.O. Paris, France This paper is intended as a little contribution to the study of the vertebral lesion familiar to the osteopathic profession. It is based upon readings from the works of foreign authors such as Claude Bernard, Ranvier, Virchow, Sappey, Testut, Poirier, Duchenne (de Boulogne), Hovelacque, Sicard, Forestier, Tanon, Tinel, Ruiz Arnau, etc.; upon readings of osteopathic literature with reference to laboratory tests at Los Angeles, together’ with personal observations and deductions. The points considered are: (1) The vertebral column as an animate beam ; (2) the intervertebral disk ; (3) the annulus pulposus ; (4) the annulus fibrosus; (5) the common ligaments; (6) the apophyseal articulations ; (7) the capsular ligaments ; (8) interspinous and supraspinous ligaments; (9) the ligamentum flava; (10) the spinal canal (protection of cord) ; (11) the intervertebral foramen; (12) blood cellulitis and neurodocitis ; lesions; (16) indirect the standpoint of mechanics the main factors’ involved are bones, ligaments and muscles; it is our purpose here, in studying some of their physiological functions, particularly in extreme range, to visualize the conditions under which lesions may be formed. Bones are rigid living structures whose functions are to maintain the form, the position, of various parts of the body, and to afford protection to the most delicate and important vital organs. In the limbs and the vertebral column they act as lever arms and compression members. Skeletal ligaments are fibrous bands which connect the bones together, maintain them in functioning position, limit and control their articular displacement. They are articular tension members. Skeletal muscles are contractile organs which produce angular movements of bones, such as that of one bone about its articulation with another. As a structure the vertebral column is essentially composed of bones and ligaments. This is most practically demonstrated by the spines so skillfully prepared by Dr. H. V. Halladay, with which the profession is fully acquainted. In such a spine there is almost perfect mobility at each articular �point, while both the individual and the total displacements remain strictly within the natural range.

Now, as the body of the fifth lumbar is the weight cannot hold, the term “animate beam” would largest of all the vertebra, and was thought purposedly probably be the most adequate to define it, both ac- intended to serve as the base of a strut and to sustain cording to mechanics and to function. Effectively, consequently the maximum load, it seems clearly inadin life, it is subjected to various kinds of bending and twisting; but whereas in an inanimate beam there is no control over the strains (or deformations) produced by the stresses, there is in this animate beam an incessant control tending to limit the displacements and the strains so as to protect the integrity of the structure while allowing a marvellous diversity of postures and a likewise marvellous precision of movement. This control is instinct&e, independent of the will, and might well be considered as a sense, in the same manner as some authors consider the nicety 13 92 of adjustment of antagonist muscles as due to a muscle sense. To uphold their contention of the vertebral column as a strut, anatomists point to the fact that as the body weight (load) increases from the head downwards so does the size of the bodies of the vertebrae and of the articular surfaces increase from the skull down to the sacrum. Without referring to this structural feature in quadrupeds, it certainly helps to sustain the beam hypothesis; and the greatest periphery obtaining at the base of the column would indicate that the control index is within the peripheral ligaments, thus governing the region where the need for stability of structure is greatest. The general aspect of the column predisposes against the strut conception; its sinuosity shows it fig. 1. already bent along three deformable arcs, and it is obvious that any anteroposterior movement, for instance, is bound to modify the curvatures, thus in- missable to maintain such an assumption, as it cannot creasing or decreasing the flexual stresses.

The plan the ratio of 1 to 2.8 to that of the fifth lumbar, which of the lumbosacral joint may be fairly accepted as affords no ground for conclusions of interest. In Fig. 2 we have a bent lever pivoted on a fixed forming an angle of 40” with the horizontal plane. By resolving the vertical force into two components, support or fulcrum ; the short arm of length is conone at right angles with the plane of the vertebral nected to the support by a spring ; at the end of the joint, and the other with that of the articular facets, long arm of length L a weight W is suspended. The it is seen that the pressure on the face is 76.6 lbs., or resistance R provided by the spring is calculated from Americanthe Academy of Osteopathy® equation of moments WL = dR, whence W L : 34.7 kgs., and that on the facetsAllisRights 64.3 Reserved .lbs., or 29.13 VERTEBRAL MECHANICS-GUY d = R. For any point along the arm, at a distance L from the point of suspension of the load, the moment is WL: it is resisted by the molecular forces of the material of the, arm. Above the neutral axis the forces are tensile, below they are compressive. For a lever arm of uniform section throughout these forces vary in intensity directly as the moment. The maximum effort is obviously at the point of support. 93 are fully applicable to this link beam. In order to fix the ideas let us analyze, for example, the conditions shown in Fig. 4, in which a man sitting on the ground, with his feet applied against a firm support, pulls �horizontally, and steadily, with both hands, a rope passing over a pulley and sustaining at its end a weight of 45 kgs., say about 100 lbs. The sacrum is thus firmly anchored, and the vertebral column is subjected to a flexural effort in an anterposterior plane. As measured on a convenient subject at hand, the lever arm or distance L from the upper face of the sacrum to a point of application of the load situated about the third dorsal, was found approximately equal to 38 cm. The maximum bending moment at the lumbosacral joint was therefore 38 X 45 = 1710. Assuming the axis of the tension forces at about 5 cm. from the center of gravity of the upper face of the sacrum, this would represent the small arm of the lever. Consequently the ligament and muscle pull would equal 1710~5 = 342 kgs. and the pressure supported by the disk through the bending effort only would also be 342 kgs. In addition, assuming for convenience’s sake, the weight of the upper part of the body as before, in the vertical position, as 45.3 kgs., the components would be 34.7 kgs. on the face, and 29.13 kgs. on the articular facets. Directly applied to the facets is also the shearing force of 45 kgs., that is the weight pulled by the hands. So that altogether there is 342 +34.7 = 376.7 kgs. on, the face, and 29.13 + 45 = 74.13 kgs. on the facets. Besides this there is a tendency to shear off the The total load divided by the area sustaining it arm at every point of its length and, neglecting the weight of the arm itself, the shearing force is pre- gives the pressure per unit of area; therefore upon cisely equal to the weight supported, and is of course the face we have 376.7: 13.92 = 27.06 kgs. per cm. sq.; and upon the facets 74.13:2.88 = 25.73 kgs. per the same a: every point. cm. sq: In round figures this comes to 385 and 366 Let us assume that the lever arm instead of a pounds per sq. inch, respectively.

Thus far we have taken it for granted that the springs, and the compression efforts are resisted by facets were bearing symmetrically upon the full exthe pads. We have thus a structure similar in mechanical action to the vertebral column, in which the tent of their articular area, and with the bending or springs S are made up of ligaments and muscles, and pressure efforts applied in one determined plane. But, the pads are the intervertebral disks. It can be easily because of the flexure of the column, the disks are shown that this form of structure, particularly with compressed, each vertebra is angularly displaced with the actual location of the articular facets in the respect to its neighbor, consequently the facets in apcolumn, may take care of lateral bending efforts, position slide upon one another, with the result that ligaments and muscles attached to the lateral ver- the bearing surface may be greatly diminished and the tebral processes resisting the consequent tension unit pressure proportionately increased.

Rights Reserved Academy Osteopathy® The stress computations for the All solid lever arm American Well, after ofpainting the facet situation in such 94 VERTEBRAL MECHANICS-GUY dark colors we would expect to obtain ready confirmation of our grave fears in the finding of more or less extensive deterioration of the articular surfaces in specimens selected either at random, or purposely. Examination of perhaps more than fifteen spines has completely failed to reveal one single case that could be �used to prop up the theory that the vertebral lesion may be caused by the abrasion or the indentation of the articular surfaces. Some of the vertebrae were seen in the dissecting laboratory; others had been buried for years in the back lots of the college town by once ambitious students ; some we're disconnected from dried up spines prepared by Dr. Halladay, and loaned by him to the writer. In some instances the articular facets were completely encased in osseous growth. In all cases the transverse cutting through the intervertebral disk required some force, particularly with very old specimens, but once the capsular ligaments or the osteophytic capsules of the facets were separated, the latter were found free from adherence, and the working surfaces smooth and unctuous to the touch. With very fresh specimens obtained from animals just sacrificed, the apophyseal processes have a semitransparent appearance, giving one the impression, because of their hardness and smoothness, of dealing with odontoid structures. Warning is in order as to hasty conclusions drawn from examination of vertebrae that have been subjected to prolonged boiling in lye solutions, and beautifully bleached; the hyaline cartilaginous lining of the facets is removed leaving rough and seemingly distorted surfaces. Ominous as are the conditions affecting. the compression members of the animate beam-even a s judged so hastily as we have-far more portentous will we find those obtaining for the tension members, that is, the ligaments. But before dealing with the latter it is necessary to examine in some detail the assemblage of two vertebrae, so as to analyze the effects of compression on the disk itself and on the surrounding organs. fibers of one layer is from left to right, that of the fibers of the preceding and succeeding layers is from right to left; in other words, the obliquity is alternating with each succeeding layer. Histologically it appears that the concentric layers are formed of connective tissue fibers bound by a sparse fundamental substance into which are found cartilage cells; we have thus the so-called fibrocartilage tissue of the texts. According to Sappey, muscle fibers may be found in the connective tissue of the layers. All the fibers are implanted at their extremities into the substance of the basement layers. The whole disk is enclosed at the periphery by the anterior common ligament whose lateral extensions are continuous with those of the posterior common ligament, and is thus encapsulated. . The disk fibers are in reality interosseous ligaments; their structure accounts for their remarkable elasticity, for of all fibrous and fibrocartilaginous parts of mobile articulations none are as well supplied with cartilage cells. Their union with the anterior and posterior common ligaments is very intimate, hence the tremendous resistance of this assemblage, capable of withstanding most extraordinary efforts without rupturing. Thus, with a freshly prepared spine, on which all the vertebral ligaments are left whole, an extreme backward bending does not tear the disk ligaments apart, but brings about the separation of the disk from the faces of the vertebrae. This is clearly shown by extravasation from. the blood vessels in the bodies, which spreads underneath the peripheral ligaments still adherent to the bones. All these ligaments are well provided with blood vessels and nerves. Because each layer is distinct from its neighbors, we may safely infer that there is a space, however harrow, between any two adjacent layers; furthermore, we have good reason to admit that this space is filled with the same substance found about the fibers themselves ; in fact, this may be easily demonstrated by making a transverse section through the disk in a fresh specimen, the various layers are seen apart from THE INTERVERTEBRAL DISK one another, and as bathed in fluid.

Upon removal of the pressure the vertebae would not change position, nor the depressed disk its form. With application of greater axial pressure the disk flattens and bulges out accordingly more, as at B. With pressure released the structure reverts to its original shape. Fresh specimens of lumbar vertebrae taken from a rabbit were subjected to enormous axial pressures in a vise; the disk bulged out considerably but remained without a trace of transudation of the fluid in the annulus pulposus. When free from pressure the structure regained its natural shape again, but the return was very slow. From quite a number of such tests the results preC sent for consideration two questions of some ima portance: (a) By what means were the contents of the disk prevented from flowing out while subjected to such abnormal pressures ?

Thinking that perhaps the central mass was endowed with a substantial compressibility we have subjected a sufficient volume of it to pressures varying from 300 to 400 lbs. per sq. inch, applied between plungers well adjusted in a strong metal tube. The volume was then reduced a little but, with removal of pressure, came back as observed in the actual disk. There is a bare possibility that in the latter the central mass contains tiny gaseous bubbles, consequently highly compressible, but we found nothing to substantiate such an assumption, and it may be safely admitted that under the pressure obtaining in the living articulation the central mass is practically as incompressible as water. (However, we must not forget that under very high pressures water is shown very compressible, its modulus of elasticity being much over hundred times less than that of steel.) It seemes probable that in the fresh state, and within the disk, the central mass possesses the same kind of elastic properties as gelatin; it Fends to regain its shape, so to speak, after an attempted deformation, differing in that from flaccid substances like grease, tar, etc. This would of course help the return of the bodies to their normal position, but to a very small degree. ciently convincing to warrant us in admitting that fact without further demonstration. So far we have dealt only with bending efforts, but the spine is capable of two kinds of twisting, one real and one apparent. Effectively, considering the normal vertebral assemblage we may conceive that two adjacent bodies may be bent axially in all lateral directions; thus one body being fixed, the other pivoting on the disk can be subjected to a movement of circumduction about the vertical axis of the first. In this there would be no actual rotation of one body with respect to the other. Similar circumduction could be practised successively on all the bodies of the column so that, starting from the base and adopting a constant inclination per couple of bodies, but for instance, bending the first couple in an anteroposterior plane, the second couple in a plane at 45 with the first, and so on to the end, we would then see the vertical axis (assumed for convenience as originally straight) describing in space a conical spiral with three convolutions, while markings which had been made on the anterior side of all the bodies, for observation purpose, would all face anteriorly, thus showing that the rotation concerned only the axial displacement and was but apparent for the bodies themselves. If we refer to Fig. 1 we note the positions of the centers of oscillation; these were carefully measured on three spines, and corresponded probably to a fair normal average. The centers are posterior for the lumbars, axial for the eight lower dorsals, anterior for the four upper dorsals, and posterior for the five lower cervicals. Such a center is understood as that of the THE ANNULUS FIBROSUS This has the important function of mechanically curvature of the surfaces of the two articular facets limiting the displacement of one vertebra with re- for any given vertebra; and as the facets act as spect to an adjacent one, while otherwise allowing guides for the relative displacement of two bodies, it freedom of flexure and rotation about the axis, follows that that displacement obtains about the corWhile the layers have a certain amount of elasticity, responding center of oscillation.

T. Still Institute, the results of which are so well described in THE J OURNAL by Dr. Louisa Burns. Lateral pressure exerted upon the spinous process of a given dorsal vertebra causes the latter to rotate about its vertical axis, which passes through the center of oscillation, and the angular displacement is SO great that, for one thing, the disk fibers are strained beyond their limit of elasticity and part of them give way, slip, as it were; what is left may not be sufficiently strong to bring back the body to its original position, and a permanent lesion is thus formed. Sometimes the return to position may take place through the efforts of “other vertebral ligaments or the chance pull of muscular tissues. Anyhow, the usual repair processes are set at once in action to remedy the injury, with consequent inflammatory and edematous reactions which may affect nearby tissues, particularly the connective sheets, as we will see later on, As with all mechanical structures subjected to bending and twisting efforts the greatest stress obtains in the fibers’ farthest from the neutral axis ; thus in a beam of rectangular cross section the extreme upper and lower layers bear respectively the greatest tension and compression; in a round rod in torsion the peripheral fibers bear the greatest shearing stress. Consequently in the intervertebral disk the peripheral layers are the most exposed to strain, whether in flexure or rotation, and the danger lies precisely in the disturbances produced in tissues and organs in the vicinity, during the various phases of even a quite normal process of repair. It has been advanced by some that the seat of lesion trouble could be generally located in the nucleus pulposus, which would then be viewed as a center; it seems, from what we have seen, that this notion is inaccurate ; it originated probably from the fact that the central, amorhous mass was called a nucleus and, as such, was thought to possess special attributes. Since the disk fibers are doomed to injury in extreme displacements it is quite logical to admit that nature has provided means of protection in the form of nerve terminals, which are plentiful along the periphery of the disk, and which may sound danger signals when the normal range limit is approached, in sufficient time to permit the body to so adjust its position as to lessen the strains in the threatened region; this would establish one important step towards the recognition of the existence of a Ligamentous, or artitular sense, of the same order as the muscle sense. THE ANTERIOR AND POSTERIOR COMMON LIGAMENTS To describe them would be merely quoting from the textbooks, but for our purpose they may be considered as performing two functions: (a) that of encapsulating the intervertebral disk; (b) that of maintaining a state of compression within the disk, serving thus as strong elastic bindings between any two vertebrae by means of their inner fibers, and connecting several adjoining vertebrae by means of their outer fibers. This action is incessant, even when the body is entirely relaxed, as in sleep. They permit varied motion between two adjacent bodies ; it is probable that they limit the extent of the motion and, because of the large amount of elastic fibers in their structure, they are subject to contracture, in the same sense as the muscle tissue itself but, precisely because of their relatively great elasticity, they are less likely to suffer from overstrain than the disk fibers. From our own observations we formed the opinion that they are the main factors in causing the vertebral bodies to return to original position when free from the action of external forces. 14 Rue de Tilsitt.

It may be noted also that in many instances the lesion involved but a slight angular displacement instead of one past the normal range of motion. A study of the geometry of the articulation will clear up the misunderstanding and establish the various directions and ranges of motion ; it will prove more interesting than an academical discussion of hypotheses. Centers of curvature If an arc of a circle coincides with an arc, or element, of a curve, the radius of the circle is the radius of curvature of the curve element, and consequently the circle and the element have a common center. The radius of curvature is always perpendicular to the curve element at any chosen point of its length. A curved surface may have at a given point thereon several radii of curvature depending on the axial- planes along which each curvature is measured. The application of these simple principles to the measurement of the apophyseal surfaces is very easy: it suffices to prepare a number of templates, such as shown in figure 8, made of bristol board, with gradually increasing radii; one end is convex and the other concave, but both have the same radii for each template. By successively trying on several templates to the faces of a pair of upper or lower facets, one may rapidly determine the correct radius and, by holding the template plane perpendicular to the curved surfaces, the direction of the radial plane, and finally the position of the required center of curvature. When the facets seem curved in more than one direction the same process is repeated with other radii until’ one is found suitable, and again a center of curvature is located. When the surfaces are spherical the two radii tried are equal and, of course, the center of curvature is common to both directions. Occipito-atloid Articulation -Starting with the upper facets of the atlas, assuming that all the vertebraae are held perfectly rigid and that the head, with its condyles bearing upon these facets, is alone free to move, we find as shown in the cut, Fig. 9, in which the radii are represented by wires, as well also the curved axis, that the radius in the lateral plane. is much greater than that in the median plane; that the upper center serves as center of oscillation of the head in the lateral plane; that the lower center seemingly is placed on a curved axis, and that it serves as a center of oscillation of the head in the median plane; that the head may be inclined laterally at first and then, in addition, inclined forward and backward; that consequently the head may be inclined obliquely along the direction of the resultant of two simultaneous movements, one lateral and the other mesial. The schema shown in Fig. 10 may help to visualize the geometry of these various displacements ; the facets are made rectangular for convenience’s sake. It remains to explain the motion of a curved axis. In a mesial oscillation alone, the head pivots about a straight axis passing through the centers C C ; but if the mesial oscillation follows a lateral oscillation the points C C occupy other positions; therefore in order to cover the whole range of motion, C C must move on an arc of a circle whose center is C,. With rectangular facets receiving neatly likewise rectangular condyles the mesial motion could not take place ; it would be necessary for the condyles to bear unevenly on part of the facet, leaving an undesirable play along the rest of the surfaces. To overcome this mechanical difficulty nature FIG. 8 has arranged that the anterior aspects of the facets are close together, while the posterior aspects are very much spread apart. Furthermore, each facet is found in many instances practically divided into two portions, one anterior, the other posterior. All of the above description may be easily verified on the skeleton by holding the skull in place upon the atlas and studying, carefully the various possible displacements ; it will be seen that it differs appreciably from that in Piersol’s anatomy, page 142, paragraph on the Movements of the Head. We should note that the articulation as a whole does not permit of a lateral translation, which leads us to a remark of great importance that applies to the whole spine. Effectively any articulation is made to accommodate only the displacements resulting from the pull of the muscles acting upon the movable bone received in that articulation, and the path of displacement is always along the plane in which the resultant pull is situated at the instant considered. The temptation is great indeed to study in detail in this article the action of the various antagonist muscles which are intended to produce the nodding, or mesial motion of the head, the side-rocking, or lateral oscillation, or the resultant displacement due to the compounding of the mesial and lateral pulls. Such a study would lead us too far, as it would have to be applied to each of the vertebral articulations. We suggest again, however, that it be pursued in our colleges, where myology deserves to be treated differently than it is in the textbooks, in which nomenclature and topography predominate, with, at the tail end, a short notice, vague and general, concerning the action of such and such muscle, usually considered as part of a group. With us, Myology should be treated essentially from the utilitarian point of view; that means to give function the first place for each muscle, which is entirely logical since, after all, skeletal muscles are intended solely to place or maintain bones in given positions, consistent with the mechanics of their articulations. Such a method All Rights Reserved American Academy of Osteopathy® VERTEBRAL MECHANICS-GUY 100 would greatly facilitate the understanding of the physiology of movements, the detection of abnormal conditions, and the development of corrective technic both generally and individually. Atlanto-axial Articulations -The first of these is the atlanto-odontoidal, the second is the apophyseal. Examination of the odontoid process reveals that movement may take place about a vertical FIG. 9 axis, producing horizontal rotation of the atlas; but as the articular face of the process is not truly cylindrical, having a double convexity, one horizonal or short radius, permitting greater angularity of motion, and one vertical of much greater radius, it follows that a small oscillation, or anteroposterior rocking is provided for. The apophyseal articulation has always proven puzzling because it presents a character of unstability quite unique among all the vertebrae. In Fig. 11 the vertical axis is shown with a spiralled arrow, indicating to and fro rotation; wires represent the radii of curvature of the articular facets which are in effect portions of a spherical surface. The upper facets of the axis have the same radius of curvature as that of the atlas, as measured in a lateral plane, but measured mesially they are upwardly convex with a much smaller radius of curvature, the center of which is located about the middle of the third cervical. In this way the faces in apposition, of each pair of facets, are not in entire intimate contact; this condition is necessary to suit the rocking motion of the atlas upon the axis, which is possible in any position within the angular range of-rotation of the atlas. The stability is insured mainly by the transverse ligament, which, although very strong of itself is further reinforced by others, the whole structure forming the cruciform ligament. The great amplitude of the angular motion necessitates special means of limitation to prevent injury to the cord. The axis of rotation of the atlas is away from the axis of the spinal foramen, and as the angular displacement amounts sometimes to 45 degrees, the spinal foramen of the atlas is much greater laterally,-if it were otherwise, the cord would be sheared off, or at least crushed. The lateral odontoid, or alar ligaments, connect the -top of the odontoid process to the occipital condyles ; although these ligaments are very strong it does not seem possible that they deserve to be called check ligaments, meaning that their function is to limit the rotation of the atlas. The small distance between the axis of the odontoid process and the point, on the outer face, of the attachment of the ligament is too short a lever to insure the security and precision of movement required. It is more likely that the checking is obtained mainly through the fibers of the outer capsules which are particularly well developed between the atlas and the axis, and also by the ligaments attached to the spinous process, since the farther away the check ligaments are from the center of rotation, the more effective they FIG. II All Rights Reserved American Academy of Osteopathy® VERTEBRAL MECHANICS-GUY may be. This point deserves a more detailed study than is found in the texts. Second to Third Cervical Articulation -Here we have two radical changes; in the first place the bodies of the vertebrae are connected through an intervertebral disk; then the articular. facets have a center of curvature located posteriorly and upwardly, whereas that of the atlanto-axial was dawnward; the change is certainly abrupt. The upper face of the body of the third cervical is saddleshaped to receive the lower part of the axis’ body. It is quite evident that true lateral displacement is not possible, nor for that matter, true axial rotation of one body upon the other. In Fig. 12 the third and fourth cervical vertebrae are shown assembled for the purpose of better indicating the positions of the two centers involved. The oblique axis provided with a spiralled arrow passes through the upper center of curvature; its direction mesially, is towards the vertical axis of the bodies, where it FIG. 12 101 increases because the lower part of the axis’ body becomes then more closely wedged in the saddletop of the third vertebra. In extension the rotation becomes ampler because less restricted by the lateral processes of the saddle, the side clearance between the lateral faces in apposition of the two bodies being then greater because of the tilting backwards of the oblique axis towards the extreme range of extension. It is equivalent to considering two V-shaped parts fitting one into the other; the more they are separated along the V axis the more lateral play there will be. All the other cervical vertebrae articulate with one another in precisely the same manner as previously described ; the only variations to be observed are the length of the radii of curvature and the position of the centers. Seventh Cervical and First Dorsal Articulation.Fig. 13 shows a most interesting condition,-that of a complete reversal in the position of the centers of curvature of the apophyseal surfaces of the seventh cervical. The superior articular facets have their main concavity facing’ posteriorly and upwardly, while the inferior facets have it facing anteriorly and downwardly, consequently the two main centers of curvature are directly opposite. Hence, the sixth cervical may oscillate about the oblique axis, as indicated by the spiralled arrow, while also oscillating in a fore and aft manner about axis C, as indicated by the double arrow at the top center, to suit flexion and extension movements. In flexion and extension the seventh cervical may oscillate about a center A located practically at the middle of the body of the first dorsal. We should note that for all vertebrae the centers of curvature and consequently of fore and aft oscillation, are located anteriorly and downwardly, and relatively at about the same point on the body of the vertebra. The seventh cervical may also oscillate about a center C. This transverse motion is however of limited extent because the upper face of the body of the first dorsal has two lateral processes, last vestiges of the saddle form obtaining in the cervical region, which act as abutments. Sometimes the attachments of the head of the first rib act in the same manner. In manipulating the two vertebrae together it is seen that there is a possibility. of an oscillatory motion about an oblique axis passing through the centers A and B. This motion is of greater amplitude than the transverse, because when one side of the seventh body bears against the lateral abutment and the head of the first rib the other is clear of such obstacles and may move through a relatively great distance until checked by the various ligaments affected. These various motions may take place separately or in combinations, while the articular facets in apposition preserve a normal amount of contact. It becomes increasingly evident as we proceed that lesions do not form through a mere tilting of articular facets, with or without actual denting of their surfaces. The articular motions have well-defined directions and ranges, guarded by efficient and very vigilant ligaments. Whenever a movement oversteps the range the ligaments are overstrained and need repairs, which nature at once proceeds to make; the affected vertebra may remain relatively displaced, with attendant disturbances in the region, until conditions are mended intersects a transverse axis passing through the middle of the body of the fourth cervical. On this latter axis is the center of the anteroposterior curvature of the upper articular facets. The axis vertebra may therefore oscillate forward and backward, that is, move in flexion and extension about a transverse axis or fulcrum passing through the body of the third cervical at about the middle of this latter. In so doing it carries back and forth the oblique axis, as indicated by the double arrow located at the upper center of curvature. In any position on this range it may also oscillate about the oblique axis, but this angular rotation is limited increasinglyAllasRights the Reserved flexion American Academy of Osteopathy® 102 VERTEBRAL MECHANICS-GUY ical vertebrae are oftener in lesion to the right than to the left sides? Our experience indicates that about 90% of the lesions are on the right side. It is interesting to consider the position of antagonist muscles intended primarily to rotate a cervical vertebra about its oblique axis. Such are the semi-spinalis colli; their origin are on the articular processes of one given vertebra, and their insertion on the spinous process of the second vertebra above. When one contracts it pulls on the spinous process laterally and downwardly; the direction of the pull is nearly tangent to the arc of circle described by the spinous process while turning about the oblique axis ; return to mid-position or rotation to the other side are, of course, produced by the action of the companion and antagonist semi-spinalis muscle. As we may realize, the position and connection of these muscles are such as to insure the most efficacious action. Incidentally, we should note that these muscles are sometimes described as “supporting the spinal column,” for instance, in Dorland’s dictionary, in muscles, a statement quite illogical. Thoracic Vertebrae.--It seems that each of the four upper dorsal vertebra7 have two centers of oscillation; one center about which mesial rocking takes place is located at the middle of the body; the other, having to do with side rotation, is situated anteriorly, as at D,, D,, etc., Fig. 14. The rest of the dorsal vertebrae have only one center common for both motions. With all the dorsals flexion and extension have relatively greater amplitude than rotation, because the latter is hindered by the abutments formed by the heads of the ribs. Taking it for granted that lesions are produced by disturbances occurring at extreme range of motion, we see in the sketch, Fig. 15, representing a mid-dorsal vertebra, that in rotation about center 0, the region a, at the posterior end of the vertebral foramen, must withstand the� greatest amount of displacement, hence of stretch. It is there that we should expect trouble. By the same reasoning, that region is likewise most severely affected in mesial oscillation, since it is located the farthest from center 0. We do not consider the extreme displacement of the FIG. 13 tips of the spinous processes because the ligaments, holding them are suitably disposed, and lax enough With the cervical vertebre lateral flexion or to withstand it. The ligament most affected is the extension are quite limited. This is evidenced on ligamentum flavum. This seems well established any patient when lateral pressure is applied to the by examination of a number of specimens in our head: the neck itself remains practically straight; possession, and is accepted by several well known but at the base of the neck, just below the seventh authors. Injury to this ligament may result in cervical, there is considerable movement, This con- processes of ossification, example of which will be dition is utilized in the technic for adjusting the shown later in the form of actual photographs. Of first rib on the side opposed to the direction of course, in extreme extension we should expect the pressure. The rotation about the posterior oblique anterior aspect of the common ligament to suffer axes, combined with extreme extension, permits of overstretching. This is very serious and may prove ready adjustment of the whole cervical area. The the beginning of wasting disease affecting the antechnic for this is extremely simple when based on terior portion of the vertebral body. Another point of serious import is the disturbthe above considerations and oriented in the direcance, through extreme rotation, to the attachment tion of the least resistance, and either difficult or impossible, therefore very dangerous, with the of the head of the rib, with consequent tilting of the cervical vertebrae in extreme flexion.

Lambar Vertebrae.--An abrupt reversal of the position of the centers of rotation takes place with the apophyscal articulation of the first lumbar with the twelfth dorsal vertebrae The centers for all the lumbars are posterior and located somewhere within the mesial plane of the spinous process, practically as shown in, Fig. 14. The centers of mesial oscillation remain, however, situated about the middle of the body of each vertebra, that of the fifth lumbar being about the middle of the first sacral. We see from the sketch in Fig. 16 that the region most stressed in rotation is at a, on the anterior face of the body; the lateral aspect of the latter comes next, the stress diminishing in intensity to the level of the posterior wall of the body. In extension the same region a is the most stressed. In both cases the anterior common ligament has to bear the brunt of the tension. Both thoracic and lumbar vertebra are limited posteriorly in extension by the abutment of the spinous processes. In flexion all the posterior ligaments help in sustaining the tension, but in all cases the ligamentum flavum is the most stressed and subject to injury. At this juncture if we consider generally and briefly the technic of the so-called correction of a lesion, with which so many seem satisfied, we see that for the cervical region it is obtained most easily with the neck in extreme extension and in such rotation as to suit the articulation aimed at; that is clearly indicated by the study of the radii of oscillation. The popping noise is produced when the facets of an apophyseal articulation, after being abruptly separated, are brought back sharply in contact through the reaction of the ligaments and muscles situated in the neighborhood. In this case, the displacement of one upper vertebra is involved, all the other vertebrae below being locked in position. Usually only one of the apophyseal articulations gives way at a time. Thus, for example, the patient lying on his back, the head and neck being in extreme extension, with the face to the right, the articulation on the left will be maintained in forced contact, while that on the right will give way and produce the noise upon its spontaneous return to position. For the dorsal area an upper vertebra must be displaced posteriorly along the long radius of rota tion as an axis, all the lower ones being locked The complete articulation (that is, the two apophyseal articulations) may give way at a time. The direction of effort must be varied to suit the axial direction suitable to each vertebra. This point has been fully explained by various authorities on technic, particularly by Dr. Taplin. In all cases, briefly speaking, the separation takes place in a direction normal to the plane of the articular facet. For the lumbar area the conditions are changed. The upper vertebrae are locked and the separation takes place through the displacement of one given lower vertebra. Thus with the patient on his right L-a-4 side, the operator presses down and posteriorly with one hand upon the *left shoulder, maintaining it in position, while with his other hand or forearm, he produces a twisting thrust downward and forward upon the pelvis. In this way the apophyseal articulation on the right side will be forcibly maintained in position, while the separation of the facets on the left side will be produced, with the usual accompanying noise. To produce the separation of the right side articulation the patient is placed upon his left side, the right shoulder being maintained firmly in posterior and downward direction, the pelvis is then thrusted forward and downward,, that is, effectively twisted. Anteroposterior lesions belong in a class by themselves and require a most attentive study of general and local conditions. They are susceptible All Rights Reserved American Academy of Osteopathy® 104 VERTEBRAL MECHANICS--GUY of reduction, but usually through extended series of treatments; quite rarely may they be corrected by a single, snappy treatment. The Sacro-iliac Articulation -Although this subject does not seem at first to fit in with the mechanics of the vertebrae, it has, however, some fundamental points of resemblance with an ordinary vertebral articulation which are worthy of close attention. I t is not unusual to have transient patients on foreign shores call on the osteopath for the purpose of having their sacro-iliac lesion corrected. If one is bold enough to ask how do they know that they possess such a rare thing, he is peremptorily informed that the osteopath at home discovered it and hammered at it periodically, so there . . . . get to work and please fix it. Invariably then, if the patient is placed on the back, one leg is found shorter than the other, which, in the, absence of specific symptoms of pain clearly indicates that the sacrum is rotated upon the lower face of the fifth lumbar (that is the most usual disturbance.) This is proven by the operator placing his left hand on the anterior aspect of the right ilium, with the right hand on the anterior aspect of the left ilium, and sharply twisting the pelvis away from the side of the short leg. The ankles are then found practically on the same level. That, of course, is merely a demonstration of fact, the correction of the lesion itself entails a conscientious preparation of the tissues affected through proper manipulative treatment of the lumbar and sacral regions, after which the replacement of the lumbosacral articulation is easily effected. Unless there should be chronic disorder in the articulation the effects of the treatment are lasting. In case of a real sacro-iliac lesion the two main symptoms are : (a) great tenderness evolved under palpation of the posterior aspect of the sacro-iliac articulation, either on one side or on both sides; (b) tenderness at the superior aspect of the symphysis pubis. This latter symptom is always indicative of sacro-iliac affection or displacement. Treatment for the reduction of such a lesion is quite involved and requires special consideration. The question of the sacro-iliac joint as an articulation has been the subject of many arduous discussions. The textbooks do not enlighten us appreciably on it, but considering the pelvic girdle as a whole, some of the older anatomists, particularly the French, claim that a movement may take place through an elastic separation of the symphyseal joint in women at parturition time. They cite certain gynecologists who have asserted that they observed considerable spreading of the bony structure, amounting in some cases to more than two centimeters. Such statements lack the stamp of general confirmation. As to the function of the articulation itself, nothing of a definite character seems to have been brought forth. Some of our people endowed with more than ordinary skill in palpation, claim that they are able to detect evidence of motion between the ilium and the sacrum; they certainly must have beengifted by nature with uncommon power. But it is not at all necessary to be so gifted nor to possess an extraordinary knowledge of anatomy to demonstrate either on an old dried up specimen or on a fresh one that, by con- struction, the joint is intended by nature as an articulation. Reverting to a vertebral articulation, we know that it is composed of a fibrous intervertebral member or disk, maintaining elastically two adjacent bodies in position, and two guiding apophyseal articulations. With any specimen it is always possible, once the capsular ligaments are slit, to introduce freely a thin flexible blade between the articular facets; the fibers of the disk are very hard to cut through in an old specimen, and relatively tough in a fresh one. Now, with a sacro-i1ia.c joint we have on each side of the sacrum an extensive and extraordinarily strong fibrous connection,. the interosseus sacro-iliac ligament, between the upper portion of the faces in apposition; by slitting the capsular ligament around the lower and anterior portion it is always possible to insert a thin flexible blade between the bony surfaces in apposition. Just as the articular facets are always unctuous to the touch, likewise are the auricular facets of the sacrum; furthermore, the latter are well provided with synovial fluid through surrounding appropriate membranes. The demonstration may easily be made on the body of an animal, a rabbit for instance; as soon as the capsular ligament is cut the ilium can be moved angularly to and fro about the sacrum. When we are convinced that the joint may articulate we want to know the purpose thereof. We cannot err very much in assuming that the function of the articulation is similar to that of a shock absorber, and that the slight give that may take place between the articular faces, through the exertion of violent efforts, as in jumping, sudden pulling or lifting, reduces the violence of the transmission of the induced stresses to the spinal colunm. The apparent shortening of one leg, as measured by the difference of level of the ankle bones, has often been too lightly attributed to a real sacroiliac lesion. Since it is so difficult for the average practician to detect movement between the ilium and the sacrum, the possible maximum displacement must indeed be very small under normal conditions, and would not, most probably, in case of an ordinary lesion, produce an upward displacement of the leg amounting to centimeter. Now it is noti uncommon to have patients showing a difference in ankle level amounting to between one and t w o centimeters, which certainly cannot be attributed to such a lesion. The explanation of such a difference is very easy if we consider the angu1ar position of the lumbosacral disk. Assuming that the angle formed by the upper face of the sacrum with the horizontal amounts to about 45 degrees, we realize then that when the pelvis as a whole is twisted, for instance, from right to left, the C O X Ofemoral articulation carrying the right leg goes down, while the other raises the left leg. The difference in ankle level is then the total displalcement of the two legs. With a bilateral sacro-iliac lesion the ankle level would be unchanged; with a unilateral lesion one leg only would be raised to a small extent, as stated above. The correction for a right to left lumbosacral twist is most obviously accomplished by twisting the pelvis from left to right, all duly in accordance with proper technic. 14 Rue de Tilsitt.

GUY, D.O. Paris PART III The Capsular Ligaments.-We have mentioned that the articular facets are lined with a strongly adherent layer of hyaline cartilage; this layer is thicker in the central portion; its average thickness varies from 0.8 to 1 mm. in the cervical region, from 0.5 to 0.8 m the dorsal, and from 0.8 to 1.5 mm. in the lumbar. Its working surf ace, although very hard, is smooth and always unctuous to the touch, even in old specimens. In some cases of esostosis where evidently the apophyses had been immobilized for a long time, it was necessary to break the bony growth all around the edge of each articulation in order to obtain separation of the surfaces, and it was then seen that the cartilaginous coverings had remained intact in the major portion of their area, the edges alone having been affected by ossification. From this we are justified in assuming that each cartilage, as a living organ, did not depend for its nutrition and its upkeep upon the fluid excreted by the capsular membranes; it seems evident that the nutrition was derived from the periosteum of the articular processes. Histologicallv, the structure of the capsule is that of fibrous tissue, i. e., numerous connective fasciculi arranged in several layers, bathed in rather abundant amorphous substance. The elastic fibers are thin and rare. Fat cells are present in the tissue; in the neighborhood of the insertions there are capsulated cartilage cells, and the fibrocartilaginous sheet thus formed becomes calcified at its contact with the bone. The main physical properties of the capsular ligaments are strength and flexibility. The strength is greater than that of tendons and even of bone. This explains the well known and observed fact that in ligamentous sprains tearing of the osseous insertion is found oftener than rupture of the ligament itself. The flexibility is very great ; that of course is common with fibrous tissue in general. It has been held that it is greater in the young and diminishes in the old ;’ obviously flexibility decreases in cases where the capsule and the ligaments are affected by ossification. Extensibility and elasticity are functions of the amount of true elastic tissue. The capsule and its reinforcing fasciculi, whose structure is almost exclusively fibrous, are practically inelastic and inextensible. When a displacement reaches a certain extent the ligament is taut and the tension naturally maintains it fixedly so; with an abnormal displacement the ligament ruptures, or tears away its insertion. However, it should be noted that if the ligaments do not stretch under a sudden traction, No. 1 they do so under a continuous effort. Thus with the foot, when the muscles are impaired the weight of the body produces a deformation of the arches and the ligaments become gradually elongated. In an articulation affected by an infiltration the capsule is distended little by little and the articular cavity becomes abnormally much greater. In these instances the elongation of the ligamentous fasciculi is due to a, modification of their structure and not to a special property. The capsule is well supplied with vessels and nerves. The arteries enter the ligaments on their periphery; they pass between the fibrous fasciculi by dividing and anastomosing, and thus form a very extensive network which ends on the inside into the synovial membrane ; the capillaries form arcades from which spring the veins; these accompany the arteries, there being generally one vein for each art&y. The nerves, very numerous, are attached to the arteries along the greater part of their traject, and form plexuses among the various networks. Some are vasomotors, but the greater number are sensory. They terminate either in unsheathed interstitial expansions or as corpuscles of Ruffini, or as corpuscles of Vater. The wealth of nerve endings in capsular ligaments explains their sensitiveness on distension, which manifests itself when the ligament is subjected to an abnormal traction, The existence of these nerve endings is probably intended as means of control of the extent of the tensions and pressures sustained by the ligaments, and consequently of the position of the articulation. The articular cavities contain a very small quantity of a clear, transparent and very viscous fluid, the synovial liquid, which bathes the articular surfaces. In this liquid are found synovial cells, either intact or in fragments; cells from the surface of the cartilages; leukocytes; free nucleii; elastic fibers; fat droplets; bits of snynovial membrane and of the articular cartilage. The origin of the synovia is not definitely known, but it is generally admitted that the fluid is a transudation of the blood serum, to which are added the waste material from the superficial cells. According to Hammar it is but the result of the liquefaction of eroded cartilaginous and synovial cells dropped in the cavity. Effectively, the chemical composition of the synovia is quite analogous with that of cartilage, and it seems pertinent to assume that it might be a sort of fluid form of the amorphous substance of the supporting tissues. This would explain that in the articulations of many vertebrates of lower orders and in the amphiarthrodias of man there are no definite limits between the articular cavity and its walls; even in the synovial layers of diarthrodias All Rights Reserved 105American Academy of Osteopathy® 106 VERTEBRAL MECHANICS-GUY this limit is not always clear. Synovia, synovial membrane and cartilage would then. form a connective whole diversely differentiated. For osteopathic purposes we should note here that the extensive vascular and nervous arrangements of the articular capsule render it susceptible to anything affecting the blood supply and the nerve conductivity. We will consider this matter again a little later. The function of the capsule is to keep the articulation covered, inclosed, protected from the influence of the surrounding tissues or organs, and to provide adequate lubrication of the working surfaces throughout the whole range of the relative displacements of the latter. The diagram in figure 17 represents at A two articular processes in neutral position ; at B the upper one is displaced to the left a considerable amount which may be assumed as within the ordinary range ; observation shows that in many instances the displacement is even of greater extent; it is not onesided and may be of equal extent to the right, for instance. To suit such conditions the capsule cannot be a mere sheet of tissue, a wrapper, possessing extraordinary stretching qualities. Effectively, in man, it is attached to the processes, outside of the articular faces, continuous with the periosteum, presenting a plurality of folds festooned somewhat as shown in figure 18, at A. In extreme range, as at B, the capsule is spread, at the left, so as to cover the underside of the upper facet, and at the right to cover the upper facet of the lower process. It is not possible, of course, to demonstrate this on a human subject, nor even on the cadaver, where the tissues’ have undergone well pronounced changes, but on the body of an animal such as a rabbit a most interesting study can be made. Once the muscular tissues are speedily removed so as to expose the free vertebral articulations, one may see, particularly in the lumbar region, conditions represented by the sketches in figure 19. At A, in neutral position, the capsule is festooned somewhat as shown; instead of being inserted at the edge of the upper process, as in man, it is so much farther up that the end of the process appears as a tooth, clear and smooth on its upper and lower aspects. Upon rocking one vertebra upon another subjacent, the capsule spreads as at B, covering the upper part of the lower facet, and as at C, covering the upper and lower surfaces of the tip of the upper process. One cannot help marvelling at the smoothness of action of the capsule while folding and unfolding, and also with the articular faces in apposition working to and fro without losing contact with one another. It is very difficult to break this contact without damaging some of the various structures involved. The observer must realize then that the notion that the articular facets act as guiding and controlling organs for the whole vertebral articulation is fully confirmed by actual demonstration. To function properly the capsule must be always in contact with the working parts so as to follow incessantly . their displacements ; even in breathing they move; it must provide synovial fluid for the lubrication of the facets and serous exudation to suit the contact with external tissues. Consequently the blood and nerve supply must be adequate and uninterrupted. As it is soft and jellylike, in a way, it does not possess, unaided, sufficient elasticity to insure very strong application against the parts; we are thus led to the examination of the structures with which it is in relation, these include the periosteum, from which proceed the blood and nerve supply, the ligamentum flavum, and the tendinous attachments of the various muscles. in the vicinity. This examination is not intended as a mere description, which could be had from standard: texts in far more precise and accurate form than our meager knowledge and experience could ever presume to present, but rather as an essay on the study of disturbing conditions leading to the understanding of pathology affecting the tissues involved and thus to the formation of lesions. These may be traumatic, caused by forceful stretching or tearing of the capsule, or consequent upon edematous occurrences produced by interference with the blood and lymph circulation, or again by toxic conditions directly affecting the quality of the blood. The Periostennz.-According to Leriche and Policard (Physiology of Bone, Paris, 1926), the periosteum is the fibrous membrane which invests the bone and separates it, from surrounding tissues: it is but that. Its morphology is not everywhere the same. Where muscle fibers attach to the bone its fibrous organization is quite different from that in which the bone is situated under a mucous membrane or under the skin.

It is highly desirable that laboratory tests should establish the starting point and the sequence of events leading to the congested condition; it is suggested that the fibrous framework plays a most important part in that process, which is well worthy of extensive investigation. It is frequent in practice to find by palpation in the dorsal region wide fibrous areas, usually deeply seated, and which, crackling under the touch, give one the impression of sheets of parchment embedded in the tissues. They are in reality atrophied muscles, as we find in our dissection work, and always indicative of previous diseases suffered by the patient, such as for instance, pleurisy, pulmonary trouble, eruptive fevers, etc. It seems as if the whole muscle had lost �its elemental cells, and that its framework had become stouter through cicatricial processes following the disease. We have found that such atrophied conditions are responsive to osteopathic manipulations, but that patience and perseverance are main factors in the reestablishment of near normal status of the muscle. That this recuperation is at all possible is due most probably to the fact that the wasting process affected the bulky substance of the muscle cell, leaving intact the nucleus and a few remnants of that substance which, through the induced hyperactivation of the blood flow, and consequent nutrition, gradually regained activity and reformed the cell. This also offers a fertile field for laboratory investigation. Fig. 20 is always better differentiated, less so, however, where in contact with the bone than at a fraction of a millimeter farther on. It possesses numerous capillaries, fibrous elements in evolution, and connective cells of a young type. It is continuous with the connective tissues of the medullary spaces which open on the surface of the bone; there is no interruption between the connective tissue of the haversian canals and that of the periosteum. It is to this layer, hardly differentiated, that a specific osteogenic role was attributed, whence the names of “osteogenic layer,” “subperiostial blastema,” “subperiostial medulla,” etc. But it is impossible to find in these cells cytological characteristics permitting to distinguish them from those of connective tissue. Ossification .-At first seemingly irrelevant, the consideration of this subject will gradually be seen of priniordial importance, in its general application, for the understanding of certain aspects of the causation and maintenance of lesions. Dr. Still was fond of parables; they. admirably served his purpose of making clear to others his explanation of life’s phenomena as he conceived them; we may therefore hope to be forgiven if, by following his method in this instance, we can demonstrate a most interesting parallel in the processes of union applying as well to inorganic and to organic matter. Let us assume that a blacksmith has to weld together two iron rods of the same diameter, a thing that we may have watched in wonder when we were boys. The two pieces are first heated to a bright red color, and each is hammered and bumped as shown at B, figure 20. Heated again; each is shaped as at C, to form what is known as a scarf. Now the stage is set for the welding proper. The pieces are then heated to an almost white color (white heat), and watched carefully until brilliant sparks fly about; the pieces are quickly jerked out of the fire and shaken to clear them of oxide and other impurities; they are assembled at the scarfed ends on the anvil and hammered skillfully until the artisan is satisfied that the union is well accomplished; the solid rod is still very hot and appears humpy about the joint, as at D; when entirely cooled, if the work has been, done with extraordinary care, the welded rod will be practically of uniform diameter throughout. The explanation of the sequence of operations is very simple: the ends were “bumped,” spread out, so as to provide a large weld surface ; the scarfing was not essential to welding, but it is an old practice and it always insures a better joint; the sparking at white heat indicated that the ends had reached the melting point, consequently were ready to flow together when quickly assembled, thereby proving that iron Reverting n o w to the periosteum, classic treatises describe, not very precisely however, an internal layer of embryonic character located in welds to iron only -when brought back to melted state. intimate contact with the bone, which would be Observation discloses that a remarkably dormant in the adult, while remaining susceptible similar process obtains in the repair, the union, of of resuming activity through the influence of irri- organic tissue of the same kind.

Thus with ankle sprain the ligamentous attachments are most certainly involved. In the fertile field of research so successfully tilled at the Sunny Slope Laboratory, where lesions are artificially produced on anesthetized animals by first forcefully deflecting and maintaining a given vertebra out of normal position, and then studying patiently the physiological and pathological developments, the gross manner of producing the lesion is well understood, but the detailed manner in which the various local disorders are generated is probably beyond the reach of direct observation. The mere displacement of the osseous part would not suffice to account for the ensuing trouble; ligaments must be torn, sprained; likewise the capsules; the disk fibers must be affected; and in many instances the periosteum may be torn, fissured, lifted. With the repair processes which are spontaneously started, with consequent hemorrhage, edema, inflammation of the various connective tissues, it is always possible to visualize some form of ossification affecting the ligaments themselves, as will be shown later, or the apophyseal articulations, or the intervertebral articulations themselves. There will be thickening of the ligaments through scar tissue formation; that may in turn affect the circulation and interfere, for one thing, with the secretion of lubricating fluid for the articulations, which would account in great part for the cracklings spontaneously produced upon movements of upper dorsals and principally, cervicals, and also for the recurrence of lesioned positions, hence for the long series of treatments necessary for their permanent correction. These considerations should make clear the ever present possibility of causing permanent damage through the practice of forceful manipulations intended for the correction of rebellious lesions.

ASSOCIATION No. 2 CHICAGO, ILLINOIS, OCTOBER, 1930 vol. 30 Vertebral Mechanics ALBERT E. GUY, D.O. Paris PART IV Osteophytic Lesions (c o n t i n u ed)-Ligamenta flava.-Standard texts at times prove disappointing, principally so in matters of great importance, which one had been led to believe fundamentally established long ago. Thus in Arthrology, as treated in the latest edition of Poirier’s Anatomy, Paris, 1926, we find a cut reproduced here in figure 21, which is intended to represent the arrangement of the ligamenta flava in the cervical region. (1) The articular facets are so disposed that their center of oscillation is located anteriorly instead of posteriorly, as was demonstrated in Part 2 ; (2) a synovial bursa is shown heavily in black between each pair of articular facets; such a construction would be highly detrimental to the proper mechanical functioning of the articulation, and a constant source of derangement; it is probable that the early investigators forced some substance like tallow or wax, for instance, inside the capsule, thus distending it, and then made a sketch supposedly representing the observed conditions; the text states that the synovial sack communicates with “a serous bursa inserted back of the yellow ligament”; one would most seriously question the existence of such a bursa, since its presence as described would not seem required for purely mechanical reasons ; furthermore, the anterior aspect of the serous bursa is not in relation with the yellow ligament itself, since the latter is shown covering the inner capsule; (4) all capsules are shown as flat membranes covering the edges of the articulation,’ instead of being festooned as described in Part 3, which is required to permit the capsules to follow the articular processes in their various and incessant displacements, and thus to properly perform their intended functions which consist mainly in protecting and lubricating the articular surfaces. The sketch, figure 22, would more appropriately than that in figure 21 represent the true condition of the various parts involved. Unfortunately we may see the cut again, when decorating the works of some of our enterprising text rehashers; which demonstrates forcibly once more the imperative need of thoroughly reliable data for the minutious analytical study of every part concerned in a vertebral articulation, in order that lesions may’ be located, their origin traced,. and their development understood. The ligamenta flava form the posterior wall of the vertebral foramen, but as the vertebrae are ceaselessly in motion, the ligaments are so made and attached that in all positions they afford the utmost protection to the cord. Their elasticity is considerable, as may be seen by freeing several vertebra of all other attachments along a portion of the column, and then exerting axial traction at the extremities ; there is an elongation of several millimeters for each pair of ligaments, which vanishes upon cessation of the traction. This proves that to a very large extent they contribute through their elastic reaction in returning the spine, after flexure, to its normal position. Q.22. In postero-anterior flexion they are all in action; in bending to one side only those on the opposite side are tensed ; in rotation all are tensed but, as we have seen in Part 2, the location of maximum strain depends on the region affected; in the dorsal this is at the most posterior point of the vertebral foramen. Obviously the ligament will be most severely strained through a combination of side-bending and rotation, particularly in quick and sudden application of the stress; and to better understand the consequences of this, it is necessary to examine in detail the structure and attachments of the tissues involved. The yellow ligaments are essentially composed of elastic fibers anastomosed in dense networks, with meshes mainly longitudinal, interspersed with strong connective tissue fasciculi. Being constantly active it is natural to expect that their nutrition and innervation are fully adequate, and yet most recent authorities could be quoted to the effect that “a few capillaries may be seen, while the nerve supply is still uncertain.” What a wonderful opening this is then All Rights Reserved American Academy of Osteopathy® 111 VERTEBRAL MECHANICS-GUY 112 for conscientious and fruitful investigation. For each intervertebral space there are two ligaments, one light and one left, adjoining at the median line, as the apex of an obtuse triangle spreading out laterally and anteriorly. There are 23 pairs, the first being between the axis -and the third cervical, and the last between the fifth lumbar and the sacrum. Each ligament is a sort of irregular quadrilateral plate, thicker mesially than externally, and of dimensions varying according to location. The upper border is bevelled posteriorly so as to attach to the anterior aspect of the lamina; the lower border attaches upon the superior border and also upon the posterior aspect of the subjacent lamina; the internal border is on the median line, where it joins the internal border of the adjacent ligament, while allowing openings for the passage of blood vessels, and where also it connects with the interspinous ligament ; the external border ends in contact with the apophyseal capsule, to which it unites, but in a manner not yet very clearly defined; it forms thus part of the posterior edge of the opening of the intervertebral canal. The thickness varies from two millimeters in the cervical region to about 3.5 mm. in the lumbar. Sometimes the fibers of one ligament extend downward, passing over the anterior aspect of the intervening lamina to unite with the subjacent ligament. The anterior face of the ligament is in relation with a profusion of venous plexuses which surround a loose fibro-adipose mass extending the whole length of the vertebral canal posteriorly, thus forming a peridermal protective mattress. The posterior face is in relation with the muscles located in the vertebral sulcus. We now have to consider what may affect the integrity of the yellow ligaments and the sequel= thereof. The first cause of disorder, and probably the main one that presents itself, is evidently sprain induced by violent and sudden traction resulting particularly from a combination of flexion and rotation elastic fibers proper do not attach directly to the bone, their fibro-elastic supporting tissue does so; this is necessary because the attachments, as they come nearer and nearer to the bone must have the structure of their fibers gradually approaching that of the periosteum, with which they are to unite, or which they may replace, according to circumstances, so that in any case the bone may be assured a nutrient, protective and controlling covering, as shown in Part 3. Because of the great strength of the ligament, while longitudinal interfibrous slippage may occur, it is oftener the case that the attachments themselves give way at places, with attendant tearing off of small bony fragments in the form of platelets or splinters, thus leaving the affected surfaces rough or striated. The injury may be purely local, as when produced by a false movement of the body itself or, as in a fall, a blow, masses of other tissues or organs may be involved. However, for each part the, repair processes organize spontaneously to suit the local needs. Considering only the ligaments and their insertions, it is certain that capillaries having been injured, hemorrhages are present, serum accumulates and an edematous condition develops; this is followed in time by metaplasia, or the gradual transformation of the cells of each tissue into near embryonic cells, a process absolutely essential, as stated in Part 3, to the mending and the reunion of the torn parts. Eventually there is resorption of the waste and superfluous materials and normal state is gradually reestablished. Because of the denseness of the ligamentous tissue and of the irritation entertained therein by the movements of the body, a long time is required for the completion of the repairs. We should note in passing that nature attempts to restrict mobilization through the stiffening of body parts in the neighborhood of the seat of injury. This, of course, is not without serious disadvantages, considering our mode of living. Fig. 23 Fig. 24 efforts, as in a fall, a blow, in pulling or lifting.

Consequently the process of ossification which is bound to follow the lifting and tearing of the periosteum and of the connective fibrous insertions results in the growth and development of bony extensions, platelets or spicules, within the mass of the upper portion of the ligaments.

Resorption may develop in two distinct ways, osteoclasis and osteolysis, or in a variable combination of both. Osteoclasis is a phenomenon of ordinary; phagocytosis which interests the totality of the elements of bone, whether the latter is alive or dead. Osteolysis is a humoral phenomenon which, dealing only with osseous and calcareous materials, interests only living bone. Resorption is after all the rupture of a physicochemical equilibrium within the colloids forming the interstitial plasma, brought about by the intervention of at least the following known factors: (a) Composition and quality of blood; (b) degree of activity of interexchanges in the region involved; (c) condition of the connective tissue, itself depending on that of the cells and principally on endocrinal secretions; (d) morphogenetic action of pressures, tractions, tangential displacements, etc., which are exerted through the intermediary of the fibrillar web of connective tissue; (e) vasomotricity as affected by the nervous system. The presence of any extraneous matter in the body is always repellent to the latter and urges it to set forth all the means at its command to bring about the removal of that substance. That is the case for an ordinary splinter, for catgut ligatures, for bone implants and spikes, etc., and it even explains the failure of one current fad, that is of gland grafting, in which the gland implant is gradually reduced to shreds, these to be eventually replaced by fibrous connective tissue. We are justified in considering osteophytic growths as extraneous matters, but while their presence may cause various derangements injurious locally or generally to the functioning of the body, their environment may be -such as to hinder their removal by resorption. Should, something occur however, capable of setting up the proper agencies, there is a possibility of modification, of partial, or even total eradication of the growths. Interesting examples are cited by very conscientious observers. Thus, in one instance, a callus had been clearly located by radiography; several months later a severe attack of grippe brought about the apparition of redness, heat and pus at the seat of the osteosynthesis; this in turn acted locally in developing hyperemic conditions, the results of which was finally, and unexpectedly, the prompt resorption of the callus. Sympathectomy is now very much in evidence; in one case of peri-arterial sympathectomy, the acute resorption of a callus located about the femorotibial epiphyses was observed both by radiography and by palpation. This is explained by the hyperemic conditions resulting from vasodilitation. One of our patients, a man 37 years old, a hunchback with a spine distorted laterally in the form of a tremendous interrogation mark, with kyphosis in the dorsal region and lordosis in the lumbar, begged for treatments in the hope of relief from digestive troubles, from severe headaches, and from pain in the feet and difficulty in walking. He had had medical attention now and then practically all his life, his case being diagnosed as one of congenital syphilis.

It would seem also that the ossification does not affect the apophyseal capsules to the same extent. Figure 26 is copied from the Thesis of J. Forestier, on the “Intervertebral Foramen.” Paris, 1922. At A there is a characteristic stalagmitic growth resulting evidently from ossification of the lower insertion of the yellow ligaments; it extends mainly between the apophyses ; the mesial aspects of the capsules must have been affected, but posteriorly the articulations appear free. At B, however, there is a well defined interlaminar ankylosis; it would be difficult to trace the origin of this condition, and unwise to attribute it peremptorily to an extension of the trouble affecting the yellow ligament. We should be guided by the rule according to which abnormal growth of bone, in this case, exostosis, does not take place unless the protective and controlling bone covering is disturbed ; disrupted by trauma, inflamed or dissolved by morbid fluids, as in rheumatismal disorders, etc. Here we may be certain that the tissular mass over the exostosis was itself affected by some disease which prevented it from applying a pressure sufficient to limit the growth of the bone and to induce its resorption. We realize now, even from the above meager analysis, the immense importance of the yellow ligaments as regards the mechanical functioning of the vertebral column and, by extension, as regards the beginning and furthering of spinal deformations, such as scoliosis, kyphosis, etc. Thus in kyphosis, for instance, we can conceive that the development of osteophytic hooks, as shown in figure 25, can bring about a limitation of spinal extension which may eventually increase, following a gradual accentuation of the osseous neoformations. The apophyseal articulations become restricted in the position they would assume in vertebral flexion and when the lesion extends bilaterally over a plurality of vertebrae, say 5.6 or more, kyphosis is established permanently and possibly irreducibly. When one vertebra is found decidedly deviated to one side, or in a position termed anterior or posterior, and there is evidence that the disorder is of long standing, there is -a strong probability of ligamentous involvement and possible ossification. Rectification of such a -condition demands extreme caution, and is certain to require an extensive period of treatment. However, experience shows that through patient, careful and insistent work, the resolution of single and multiple lesions involving osteofibrous complications has been realized in innumerable instances, evidence thereof being the rectified and straightened spines which have served greatly to establish the reputation of osteopathy throughout this country. The facts are there, and in various ways we know that rectification has been effectuated; we also know that to accomplish that it has been necessary to disrupt osteofibrous growths, a process so much dreaded, and against which we have. Issued earnest warnings; how can we now reconcile our fears, our warnings, and our successful results? In the first place, the manipulative process has been slow and methodical, and then we have had succor from the most wonderful assistant imaginable : circulation.

Effectively, upon severing them the spine was easily restored to nearly its normal shape. That this was not an exceptional occurrence was proved by repeating the dissecting process in exactly the same manner on other specimens. This brings us back again to the characteristics of fibrous connective tissue, one of which is being highly hygroscopic, that is, capable of expanding or shrinking according to the amount of ambient moisture; but of course the question of the effects of the dessication itself is too trite to mention, for they are well known as a constant source of annoyance in dissection work. The outstanding point is that the force of contraction acting on the spinous processes as levers, produced the actual separation of the disks from the vertebral bodies. We must realize that there are numbers of circumstances in life in which extreme contraction of the muscles is apt to cause intense disorder in ligamentous attachments and in articulations. Seemingly insufficient attention has been given- to this matter as re- 117 gards the initiation of deep seated trouble in various parts of the body. As an instance, the separation of the disk must entrain considerable hyperemia, exudation, inflammation, metaplasia in the different tissues involved, and if the repair process is disturbed in some manner the consequences may be of the gravest import; besides exostoses in some vital places, there may be softening of the vertebral bodies and wasting of their substance. Clinically we have been able to trace the origin of an appreciable number of cases of partial paralysis, affecting either the lower or the upper limbs, to prolonged immersion in cold water, or to cold exposure. In treating such cases much work is required every time, to overcome the muscular contracture, but the operator is bound to realize that the trouble lies deeper and that the ligaments are so involved that the vertebral bodies are drawn together with tremendous force. It is only when the ligamental contracture is gradually overcome that flexibility begins to manifest itself and that slowly, very slowly, improvement develops.

G UY, D.O. Paris PART V The Vertebral Canal and the Intervertebral Foramen.-Dual Circulation. By definition a foramen is No. 3 Bernard in his “Lessons on the Physiology and the Pathology of the Nervous System,” 1858, and on the “Properties of Living Tissues,” 1864. Here incidentally, we find the most emphatic confirmation of the well founded osteopathic theory. According to Claude Bernard the vascular system is subject to the influence of two nervous systems, more or less distinct: the sympathetic and the cerebrospinal; the first is moderator of the vessels; its stimulation produces varying degrees of vasoconstriction, thus hindering or slowing down circulation. On the contrary, stimulation of the cerebrospinal fibers produces vasodilation. That is all there is to the mechanism of the influence of the nervous system. Through these two modes of action, constriction or dilation of the vessels, the nervous system governs all the chemical phenomena of the organism. Vasoconstriction is the contraction of the muscle fibers in the sheaths of the vessels, contraction induced by sympathetic nerve fibers; vasodilatation on the contrary is induced by the inhibitive action of the cerebrospinal system upon the sympathetic. The purpose of sympathectomy is then, through resection of certain nerve fibers, to induce a greater influx of blood to a given part and a considerable exaltation of chemical phenomena; modification of the regime of circulation may prove beneficial in the reduction of congestion affecting an arthritic joint, for instance, and may prove a factor in rapid ossification in fracture zones by establishing the required connective tissue medium suitable for the utilization of material freed by resorption, etc. The famous motto of Dr. Still about the supremacy of the rule of the artery, which was the constant guiding fanion of his untiring activity, is here upheld by one of the most illustrious of French physiologists, and that alone should be a most precious encouragement to the followers of Dr. Still. But Claude Bernard tells us that instead of resecting the sympathetic fibers to obtain the effects he mentioned, a sensory nerve of the cerebrospinal system may be so stimulated as to react upon the sympathetic and to inhibit its influence. Thus, in a most elementary experiment, the pinching of a body part causes it to redden through inhibiting (paralyzing) action upon the muscles of the blood vessels, which then acquire a larger volume and thus contain more blood. Likewise when a gland begins functioning, at first pale it becomes turgescent, the blood rushes to it because of the modification in size of the vessels. Thus anywhere the chemical actions are intensified there is sympathetic an orifice or short passage; its importance seems inversely proportional to its length, for the intervertebral duct in its extent of five or six millimeters carries “Caesar and his fortunes,” not only metameritally but also systemically through numerous reflex mechanisms. Within it are adequately organized the means required for the protection and the nutrition of the nerve fibers which, just issued from the cord, conjoin at a point ceaselessly disturbed by the physiological motions of the body parts, consequentiy always fraught with danger, to prepare their interstitial entry and progress through the tissues and organs to which they convey regulating and controlling impulses and stimuli. That the function of the various body organs is dependent on the nervous influence, in the sense understood nowadays, has been progressively realized since the seventeenth century ; witness for one instance the magistral memoir of Pourfour de Petit, presented to the Royal Academy in 1725, in which are related his experiments dating from 1717, establishing the connection between fibers issuing from the three first dorsals and the ciliary muscles; these fibers ascend through the cervical sympathetic chain to the superior cervical ganglion and the carotidian ramus, thence anastomose with the Gasserian ganglion, pass through the ophthalmic ganglion, to finally reach the ciliary nerves, dilators of the pupil. Evidently this important discovery has not received practical application outside the osteopathic realm, and like many others evolved from the patient labors of learned physiologists, has but a. topographical value. The tendency to treat disease topically has predominated throughout the ages, and though many modes of treatment might be adduced to combat this statement, the rebuttal itself could be proven but apparent; thus in cases of germ pathology a friendly germ or a friendly antitoxin were sought to overcome the bad germ and its toxin that had squatted somewhere in the body; serums were devised galore either to overcome the germ in its own habitat, or to fence in the body generally against its invasion; radium rays, electric rays, were applied certainly with topical intent; light rays are in vogue ; and to crown it all we have a tremendous surge of sympathectomy. This latter is at once a inhibition, hence dilatation of blood vessels.

It is selfAll Rights Reserved American Academy of Osteopathy® 120 VERTEBRAL MECHANICS--GUY All Rights Reserved American Academy of Osteopathy® VERTEBRAL MECHANICS-GUY evident that any muscle element must be under the control of at least two kinds of nerve action, sensory and motive, in so far as its main function is concerned. Resuming, we see (1) that certain degree of blockage of the capillary flow may produce anemic or ischemic conditions; (2) that constriction of the vessels may induce congestive conditions; and (3) that this blockage and that constriction are controlled normally by the action of vasomotor nerve fibers derived from the sympathetic system. In disease it is but natural to expect that the conditions of the affected tissues and fluids must exert a decided effect upon the nerves, in some cases intensifying their action, inhibiting it in others. By means of the above and of other data concerning spinal recurrent nerve fibers, mostly all of which was gathered purposely from old and reliable sources, we believe it possible to visualize more logically the development of the lesion, instead of remaining meekly contented with the rather indefinite, common notion of its generation through pressure on the nerve roots in the intervertebral foramina. The Intervertebral Duct.-Figure 27 is a schematic transverse section of the vertebral canal and of its two adjacent intervertebral ducts; at the left are shown the main elements to be found in the duct, and at the right the radicular arteries and the various ramifications of the nerve of Luschka; the plane of the section passes at the upper edge of the apophyseal articulations. There was no special purpose in selecting the fifth and sixth dorsals for an example, except perhaps that they seemed suitable to represent average conditions of structure. The contour of-the vertebral foramen was drawn accurately from the sixth vertebra of a male subject of large proportions; a template of it, made to scale, fitted almost exactly that of the second dorsal of a female subject of average stature, but no conclusions of value may be derived from that just now, except as to suggest a line of investigation. The proportions of the osseous parts are correct, but those of the cord, of the roots, and of the various membranes and ligaments are problematic, although based on findings gathered from a number of reliable sources. The osseous contour of the duct is formed anteriorly by the posterior external part of the fifth dorsal, whose pedicle arches over to the upper edge of its lower articular facet, thus forming a curved roof; the posterior aspect is formed by the anterior surface of the articular process of the sixth dorsal; it is continued by the upper surface of the 6. D. pedicle, forming the curved floor of the duct which ends at the upper edge of the 6. D. body ; the remaining gap is filled mesially by the intervertebral disk, and externally by the insertion’ of the head of the sixth rib. The bony surface is covered by the periosteum to which are added fibrous tissue extensions from nearby ligaments, such as the anterior common lig.; the posterior common lig. ; the stellate lig. ; the costomeniscal lig. ; the yellow lig., the location of which is well understood ; the capsular attachments of the apophyseal articulations. Externally the orifice is closed by a sort of felted mass of fibro-elastic tissue spreading far over the border, where it appears as an extension of the continuous fascia which lines 121 the periosteum on the anterior and posterior aspects of the vertebral bodies, as well as on the transverse processes and attached structures. This mass extends also well inside, for perhaps one-third of the length of the duct; some foreign anatomists have termed it an operculum and consider it as performing the function of a drum membrane, as the tympanum in the auditory canal. In this they have been influenced by the fact that they dissected dried specimens in which the mass had condensed to the point that it appeared as an actual plate. On fresh specimens from animals in a butcher shop such a plate does not exist, in its stead we may readily observe the felted mass. The intimate connection of, the operculum with the fascia is most interesting, in this sense that disturbances befalling the latter are bound to affect the former and thence the organs in the intervertebral duct. The operculum attaches also unto the costomeniscal ligament, a fibrous fasciculus which extends from the posterior aspect of the head of the rib, through the intervertebral duct, under the posterior common ligament, and fastens upon the posterior aspect of the disk. Movement of the head of the rib may cause this ligament to pull or twist the border of the operculum. The latter has many orifices through which pass the nerves, arteries, veins and lymphatic vessels issuing from, or entering, the duct; it is closely attached to each of these organs and ensheathes them for some distance externally, just as a fascia. Much has been said and written about the compression of the nerves in the duct, but the conclusions have been far from convincing. The reason therefore is most probably that the compression has been considered from the viewpoint of bony displacements. It seems to us that the matter may be more profitably discussed by dealing directly with actual structural conditions. Figure 28 represents drawn to scale, but enlarged, the external aspect of the intervertebral foramen formed between the fifth and sixth dorsal vertebrae from the spine of an adult subject; no special attempts were made in the selection of these because, except in cases of abnormal shapes or sizes, any two adjacent vertebrae should answer the purpose of the study. The delineation of the foramen and of the articular facets is very close to shape ; that of the bodies themselves is schematic. We see that in extreme extension the movement is limited by an abutment at A, formed (in this particular instance) by a bony edge ; it is also restricted by the contact of the fifth spinous process with the posterior ridge of the sixth; this is not shown in the All Rights Reserved American Academy of Osteopathy® 122 VERTEBRAL MECHANICS-GUY figure; we may note in passing that in forced extension there is a possibility of great trouble due to the fact that the spinous contact is unstable, and therefore the fifth process may be deviated laterally and made to slide on one side of the sharp crested sixth spinous process; the local consequences of such an occurrence may be: tearing of the supraspinous and interspinous ligaments, gaping of the apophyseal articulations, forced rotation of one body upon the other, overstraining of the capsular ligaments, overstraining of the so-called operculum. In extreme extension the area of the foramen is at a minimum, yet there seems no reason to fear for the contents of the duct, for the upper facet has traveled to the extreme range provided by nature and, unless the position should be unduly maintained, the temporary compression of the contents must be comparable to that of the vessels and nerves in a normally fully contracted muscle. The normal outline in the figure is of course assumed as is also that of extreme flexion ; both may be accepted as fairly correct. In this flexion the foraminal area is at its maximum, consequently the operculum, or occluding membrane, is stretched to the limit; this would seem perhaps more important as a disturbing element than the compression of the contents, for measured diagonally the fibers must be stretched about one-fifth of their length in normal position, and we would expect a tremendous pull on the attachments to the contents of the duct. As both extremes of flexion and extension are within the physiological range, and as there is nothing on record regarding the development of lesions due to the opening and narrowing of the foramen, we must assume’ that nature has provided some means of adjustment of the parts, whereby the ceaseless relative displacements of the vertebrae may occur in our daily activities without producing pathological derangements. We are led to assume that the concept of some of the leading anatomists who describe the operculum, in books issued within the last few years, as a membranous plate of appreciable thickness covering the foramen, is untenable and that, instead, the occluding mass, as we have observed ourselves, is not merely made up of elastic fibers capable of extensive stretching, but is formed- as a flexible spout, drawn inwards during extreme flexion, and pushed outwards in extreme extension. In view of the fact that many lesions are detected, treated and corrected, in which the vertebrae affected are found temporarily immobilized in positions well within the range of physiological motion, we feel amply justified in reaching the conclusion that the pathological condition of the contents of the duct did not proceed from mechanical compression caused by the narrowing of the duct, nor by the pull incident to the extreme stretching of the operculum of course we must not lose sight of the fact that while the palpation, or even the radiographs, may show the vertebrae practically in place, there is a possibility that the lesion was actually produced through a sudden displacement of much greater, amplitude than the normal, with consequent pinching or other injury affecting the spinal nerves; after which the spine may have, even spontaneously, resumed its alignment, while thence on the developments of the lesion followed their course according to the gravity of the case. It is obvious that the consideration of such an occurrence cannot impugn our conclusion. There is an aspect of the question upon which we desire to call attention with the utmost emphasis, as it has been thus far totally ignored, and we suggest that its study be undertaken in our research and college laboratories at an early date ; the attendant work consists of minute dissection, and its success depends on clear and unbiased observation. In pounding over and over again figure 28 we were led to visualize the possibility that the’ operculum could be attached firmly to the bony structure of the upper vertebra, extending across the greater part of the foramen from B to C to D and thence to B, in the manner of a loose tympanic membrane, while the lower part attached to the subjacent vertebra could have folds and festoons. In this manner the motions of the upper vertebra could take place without disturbing the nerve and vessel bundle which, implanted in the operculum, would be carried up and down with it. Such an arrangement may be represented schematically as in figure 29; the capsule which must have entire freedom of displacement is underneath the operculum; the latter is attached beyond the capsule to the body of the upper articular process, and it is continued �by the common fascia ; it is attached also to the ligamentous structures maintaining the head of the rib in the seat provided on the edges of the vertebral bodies. We hope that our suggestion may be acted upon and that the results of the investigation may clarify this most interesting point. Contents of the D&.--Within the duct are: (1) the radial nerve, formed by the apposition of sensory and motor nerve fibers, and sheathed in extensions of the meningeal membranes ; (2) the terminal strands of the posterior root at their union with the ganglion, the ganglion itself, and the strands of the anterior root; all these structures have meningeal sheathings ; (3) the spinal artery ; (4) at least one spinal vein, sometimes several, draining the blood from the cord and the nerve roots, from the meninges, from the ligaments and other supporting tissues, from numerous and extensive plexuses ; (5) venous plexuses ; (6) lymphatic vessels ; (7) loose epidural supporting tissue ; (8) an epidural sheath surrounding (7); (9) a fibroadipous mass filling the annular space between the epidural sheath and the periosteum lining the duct; (10) the nerve of Luschka, or N. sinu vertebral, or N. recurrent meningeal.

We have already described some of them in the Journal of Osteopathy, Kirksville, 1927. Their consideration coupled with the findings of Claude Bernard and of Dr. Tine1 will prove valuable in the pursuit of our subject. A live rabbit was secured on a board, and an incision made as to permit the sciatic nerve to be exposed for a length of nearly two centimeters. The wound was spread apart in cup shape, with the nerve at the bottom and its surface entirely free from contact with the surrounding tissues. Then, water at the temperature of the animal, was allowed to flow in the cavity without impinging upon the nerve itself. In this way the temperature was maintained practically constant and the bath remained really aqueous. Effectively, if the cavity had been merely filled with water, the latter would have diffused into the surrounding tissues which, in exchange, would have given up part of their plasma, so that the nerve would have been bathed, not in water, but in a heterogenous mixture of water and blood serum. After an irrigation lasting twenty minutes the nerve had lost all its properties. Electrical or mechanical excitation produced neither pain nor motion, whereas above the denuded region the nerve was still sensitive, and below was still motor. It was observed that after a few minutes of irrigation water must have begun its action upon the nerve, causing an excitation evidenced by convulsive motions of the leg involved; these gradually ceased and the irritability of the nerve diminished progressively. Another experiment was conducted on a rabbit, the two sciatic nerves of which were exposed and prepared as before. One was irrigated with tap water and the other with a 5% saline solution, both at the same temperature of 30° C. After twenty minutes, the nerve in the aqueous solution had lost all its properties, whereas that in the saline solution was perfectly sensitive and remained so even after one hour of irrigation. On another rabbit the saline irrigation was maintained for five hours, and it was found that the nerve responded perfectly to various stimuli. In one test, after twenty minutes of aqueous irrigation the wound was closed, and three days afterwards functional tests of the nerve were made ; it was then seen that the segment below the irrigated part and which, immediately following the experiment had retained its properties, had now lost all its excitomotor power along it5 entire extent. The nerve was then removed, treated with osmic acid and prepared for microscopic examination. It was seen that modifications had taken place exactly similar in kind to those manifest in the peripheral end of a sectioned nerve. Water had thus stopped permanently the conductivity just as would obtain through section with the knife. T he modifications in the nerve structure were practically the same with the aquous as with the saline irrigations. Water penetrated at the node, pushed the myelin on each side away from it, perhaps absorbing a little of it; the axis cylinder, then in a medium becoming more and more aqueous, gradually swelled up until it filled all the space from which the myelin was displayed, limited only by the sheath of Schwann and the protoplasma sur- 125 rounding it. We must regretfully leave aside the wealth of details given by Professor Ranvier, and conclude rather too briefly that the saline solution, while penetrating at the node and swelling the axis cylinder did not, as the aqueous, alter the essential parts, so that these were not disorganized and the nerve fibrillae remained good conductors of the nervous influx. The saline solution is ordinarily used for intravenous injection after severe loss of blood ; its density and action resemble those of animal fluids ; hence it does not seem too strange that it was without marked effect on the nerve fibers; the lesson these experiments teach us is that any change in the composition of the body fluids in contact-externally-with nerves is bound to affect the structure of the latter, and to a certain extent their function, depending upon the degree of diminution of the alkalinity of the fluids, consequently more so when the latter is neutralized and when acidity may be present. (Although the plasma may contain a dangerous amount of carbonic oxide, the blood as a whole must of course retain an alkaline reaction, failing which life would come to an end). Role of the Meningeal Membranes in the Infundibula. -In his thesis, Dr. Tine1 lays the greatest stress on the circulation of the cerebrospinal fluid within the restricted spaces between the roots and the internal aspect of their envelopes, and accepts as proven that any meningitis tends to promote radicular lesions of a tabetic kind. If by meningitis we understand the disease in general as diagnosed according to specific symptoms, the matter is far less interesting for us than when we consider the definition of the word itself: meningitis meaning inflammation of the enveloping membranes of an organ. The archnoid is composed of two layers separated by a capillary space. Bichat in his “Treatise on Membranes” (Paris, 1800), described it in great detail as a serous membrane intended for the protection and the insulation of delicate organs. To that effect the inner, or visceral layer, follows the nerve roots to their confluence in the infundibula, then reflects upon the internal aspect of the dura, at first loosely, as a parietal layer which, further on, adheres strongly to the dura in the form of an endothelial film. The interlayer capillary space contains a fluid whose obvious function is to lubricate the surfaces in apposition, thus permitting their free relative displacements, and also preventing their adherence ; this would show that provision was made for an infundibular adjustment of the roots to the motions of the spinal column. It has been observed in cases of inflammation of the arachnoid that a considerable viscous exudate was present. The normal fluid must originate from some kind of transformation of the blood; it his subject to deterioration and is the recipient. of waste materials from the vicinal tissues, hence it is imperative that it should be evacuated; therefore there must be an active circulation serving particularly such an essential membrane; any such circulation must be under the control of nerves. Consequently, a cause producing dysfunction of these nerves would induce disturbance of the circulation, congestion, inflammation of the arachnoid, hence local meningitis, hence formation of a noxious medium surrounding the roots, with all the serious consequences mentioned All Rights Reserved American Academy of Osteopathy® 126 VERTEBRAL MECHANICS-GUY heretofore; We see then that it is not necessary to invoke the impeded circulation of the cerebrospinal fluid as the main causative factor of meningitis. In fact much could be said anent this circulation; if it exists as such, it must be controlled very adequately by special means to suit the delicate organs �bathed by the fluid in the infundibula, a n d n o w h e r e do we find a description of these means which, besides, would necessarily be under nerve control themselves. An interesting statement is found in Poirier’: Anatomy regarding the finding of ossiform plates on the arachnoid, often on the spinal, more rarely on the cerebral. These plates, more common in old subjects and in chronic diseases of nerve centers, were found also in the spine of normal subjects in the proportion of six in twenty, four of which were in twenty-five to thirty-five year old individuals. They are usually multiple, star-shaped, and formed of fibrocartilage infiltrated with calcareous salts. This is of extreme importance far us as it permits to visualize the unsuspected existence of chronic spinal lesions, a subject to be considered later on. Vertebral Mechanics ALBERT E. G U Y, D . O . Paris PART VI The Intervertebral Duct.-Nutrition and Elimina- tion-As the cells, tissues and organs of the body proceed towards higher degrees of specialization their needs in nutrition and elimination likewise increase in importance. To the brain, because of its conscious or subconscious functions, is assigned the first place ; the cord and its spinal branches occupy the second. In each case the vascular system is specific; thus, the spinal branches having for function the conveyance of messages from distant organs to the cord, reporting certain conditions affecting them, and from the cord to the former, commanding consequent requisite action to entertain normal conditions in these organs, and all this while the spinal column undergoes ceaseless physiological displacements, it is to be expected that all precautionary measures are provided for safeguarding the integrity of such vital transmission work. Each nerve filament has a function of its own, to perform which it must be closely insulated; then it must receive an ample supply of arterial blood; but this blood must be supplied to sheaths of the &lament in such a manner that the insulation be not disturbed and, furthermore, that the nerve current, or impulse, be not affected by even the attenuated pulsations of the capillaries. The venous drainage must be arranged in similar fashion about the filament, and then suitable means must be provided to insure its rapid discharge into the systemic circulation; such means are of use also in activating the flow of the lymph in its various channels. We have seen in Part V that arterioles and venules are controlled by nerves which insure their physiological function, and we may now review the distribution of the circulating organs within the duct and the vertebral canal so as to better visualize the effects of lesion disturbance upon the radicular nerves themselves. Unfortunately, anatomists are weak as concerns the description of the spinal vascular system; they are at variance with one another on a number of important points ; and nowhere can we find a clearcut realization of the very essential role attributed by nature to the spinal circulation. Here and there we find some memoir, some paper, dealing with one single aspect of the question; one deals with the arterial system alone and demonstrates that its disturbance may engender all sorts of disorders; another deals faintly with the nervous system ; the lymphatic organs are but lightly touched upon ; or the cerebrospinal fluid is accused, through a possible stagnant state, of harboring disease germs; another points out the inflammation of the fibro-adipous tissue as the main factor in the production of pressure upon the radicular nerves; we have also the self sufficient and exceedingly vague concept of the osteopathic lesion which satisfies extremists with the notion of bony displacement, bony pressure, while others, more mature, All Rights Reserved American Academy of Osteopathy® VERTEBRAL MECHANICS-GUY think in an imprecise manner of contracture, of tissular inflammation; but nowhere do we find a true realization of the essential role played by the nerve of Luschka upon the regulation of all the spinal organs, consequently upon the whole of the organism. We shall essay to deal with these various items later on in a general review. As for the regrettable divergence of views regarding the circulation proper, that is excusable because the dissection material had to be accepted just as luck presented it, with subjects sometimes more or less abnormal, affected by acquired diseases or by congenital conditions. The arterial system of the cord is continuous with the cranial vessels and is, in addition, fed by some sixty branches issued from 34 or 36 different arteries. Anteriorly, two branches originate from the vertebral arteries, proceed downwards a little and fuse together, in the embryonic period when the anterior funiculi become apposed, to form a single vessel extending to the filum terminale. Posteriorly the two branches, originating also from the vertebral arteries, continue separately down to the conus medullaris, where they unite with the anterior artery. The three mains are connected all along their path by numerous anastomotic rami, the whole forming an extensive network. The anterior spinal artery descends along the anterior median fissure of the cord, giving off (1) central branches ramifying to feed the anterior horns, the commissural region, the base of the posterior horns including Clarke’s column; (2) peripheral branches inserting into the radiating fissures of the cord and of the anterior roots. The posterior spinal arteries run downwards either in front or behind the posterior roots; their peripheral branches also insert in the fissures of the cord, particularly through the posterior median fissure, the intermediary and posterior collateral fissures, and feed the major portion of the posterior horns. Arterioles branch out to connect the mains to the radicular arteries running along the roots. We should note that it seems proven that the central branches reach a motor area in the gray substance, while the peripheral feed a sensory area ; furthermore, the territory covered by a central artery being greater than that of a peripheral artery, the effects of a vascular obliteration, such as from an embolus or a thrombus will be of greater import in the first than in the other. The capillary vessels which connect the arteries and the veins are disposed in simple systems uncomplicated by repeated subdivisions and reunions. Their networks are modeled to suit the nervous elements they surround. The venous arrangement resembles the arterial fundamentally while differing from it on several important points; thus there are also central and peripheral veins, but whereas the arteries represent the largest portion of the afferent vessels located on the central aspect, the central veins are small and the major part of �the blood flows out through the peripheral veins, mainly through the posterior ones; again, except for the anterior median vein,. the veins are not in general satellites of the arteries, and they belong rather to the solitary type with an independent course, The lymphatic vessels of the cord and of all nerve centers have an altogether particular conformation; instead of being independent canals as 127 in other organs they are arranged in continuous sheaths around the vessels, whence their name of “lymphatic sheaths”; such a disposition may be observed on the mesentery vessels of various animals, particularly the frog. Arteries, veins and lymphatics are contained within the pia mater enveloping the cord; their extensive anastomotic networks therefore enclose thoroughly the latter. The continuous arterial network constitutes a reservoir of blood supply, just as in the periosteum, and thus insures both a regularity of supply and of pressure. There is thus a physiological vascular homogeneity which overcomes the possibility of segmental distribution. Inside the cord the capillary endings do not enter squarely the nerve elements; the entrance is in the supporting tissue, running parallelly with the elements. This is one of the natural safeguards alluded to before, it serves to attenuate even the effect of the pulsations in the afferent vessels on the nerve flux. The arteries of the intervertebral foramina, or spinal arteries, are derived according to the region considered; in the cervical area, from the vertebral A. which passes through the first interspace, and for the eighth cervical, from the ascending cervical A.; in the dorsal area, from the intercostal arteries; in the lumbar area, from the lumbar arteries. Each of these areas deserves a special study which, however, would be out of place in this very limited work, therefore we may consider only the vessels in the middorsal area. The spinal radical artery enters the intervertebral duct and follows closely the nerve; at the confluence of the two roots it divides into two main branches, each of which follows closely the filaments of one root to their emergence from the cord, and ends into the fibrous structure of the pia mater, where it anastomoses with the branches of the spinal arteries proper. The main function of the radical arteries is then to supply nutrition to the spinal roots; besides this they supply blood to all the organs in the duct and in the vertebral foramen; that includes the periosteum of the body posteriorly, of the pedicles, of the laminae, the -posterior common ligament, the ligamenta flava, the fibroadipous extradural supporting tissue, the dura mater, the various fibroconnective tissues, the capsular ligaments, etc. The arteries supplying the nerves are known generally as vasa nervorum ; aside from this nutrient function they perform another which may at times assume a great importance in the matter of collateral circulation. Long ago a number of clinical observations revealed that, contrary to the common assumption, this circulation takes place only to a small extent through the muscle arteries and that it follows mainly through the vasa nervorum. Thus, each nerve being accompanied by one artery, which receives from place to place a series of anastomoses from nearby vessels, collateral pathways are then naturally formed. In a number of cases nerve vessels were found greatly dilated by blood deviated from its normal path; in others such a condition was positively traced to the obliteration of one large artery. It became obvious that the collateral circulation must be insured in a threefold manner: through the muscle arteries, the cutaneous arteries and through the vasa nervorum. Whether the nerve All Rights Reserved American Academy of Osteopathy® 128 VERTEBRAL MECHANICS-GUY is subcutaneous or deep, the arterial supply is ar- except, however, around the four veins.

It is obvious that the effects of these disorders are not merely local, although they may develop within a region either more intensely lesioned or possessing an abnormally deficient resistance, t h e y m a y extend to distant areas through direct mechanical connection, or through nervous reflex action. The arterial networks, because of their natural robustness, may perhaps withstand the compression at first better. than the venous systems, but in time they are bound to suffer also; then the nutrition of the nerve filaments will be directly involved, the consequences of which can be easily conjectured, depending upon the regions considered. Because the lymphatic circulation is a slower process it is possible that the effects of compression are less consequential than upon the other organs, although they are bound to become so in course of time, particularly as regards elimination of waste materials, so important in everything concerning nerve upkeep and function. As to compression of the nerve itself, as a main causative factor of pain and of functional disturbance, that is a point which has been originally maintained at the front rank by many of our profession; there is no doubt that mechanical irritation of a nerve, such as pulling, squeezing, twisting, has a disturbing influence both local and distant, but it would be quite unwise to jump at a final conclusion in this matter; and above all, we must leave to others, insufficiently versed in the art, the responsibility of advertising far and wide the unfortunate notion of the osseous impingement upon the nerves as the common basis of all pathological derangements. And so, it does not seem to us that the compression of the nerve roots within the duct, as a result of the hypertrophy of the fibro-adipous mass is as portent as the pathological condition of the vascularization of the nerve filaments themselves, and mainly of the surrounding tissues. In fact, we may go a step further and fully accept as axiomatic a conclusion arrived at by Claude Bernard, i. e., that the vascularization of an organ produces effects which reach throughout the course of the nerves connected to it. The truth of this statement holds even concerning purely physiological functions ; thus in experiments on animals in a state of fast, pronounced irritation of the pneumogastric nerve was unproductive of pain symptoms, whereas during digestion the slightest irritation of that nerve provoked painful sensations manifested by the cries and convulsive movements of the animals, and yet no morbid transformation was involved in these cases. There exist then variations purely physiological of sensibility, which are so much more important to know that the sensory nerves are the most powerful intermediaries in the generation of diseases, and that the motor centers receive in many instances 129 their excitations from the periphery. In the above examples it is certainly not in the brain that we should seek the cause of the great difference in sensitiveness observed in the pneumogastric between the conditions of fast and digestion; we should find it at the periphery, at the nerve endings in the stomachal mucosa, which is seen tumefying and reddening through contact with food, whereas it remains pale and exsanguine when the stomach is empty. The affluence of blood about the nerve endings appears then as the real exciting agency, or medium, which permits the development of such an extraordinary modification of the nerve sensibility. The question of how the latter takes place is most entrancing. Our hypothesis is that in fast the antagonistic activities of the pneumogastric and cerebrospinal nerves are in latent equilibrium, there being no substance in the stomach capable of stimulating sensory reflexes, the viscerospinal nerves are at rest, and irritation of the vagus produces but a local effect of vasomotion, hence without pain symptoms ; in digestion the sensory nerves are in action as detectors of biochemical requirements, and the vasomotor nerves function as regulators of pneumogastric constriction or relaxation impulses ; consequently, when an external agency, such as the experimental irritation of the vagus, comes into play, the function of the latter is contraried, which means that at a critical moment of digestive activity there is a vasocerebrospinal unbalance, the circulation is deficient in one way or other, and the sensory nerve endings are affected, most probably by resultant hyperacidity, whence the pain symptoms observed. Furthermore, inasmuch that many distributing agencies are known to affect the digestion process, such as emotional stresses, exposure to abnormal temperatures, shocks, etc., it seems to us that the same reasoning would apply in the analysis of the sequence of events obtaining in the development of nervous unbalance leading to discomfort or even to disease. According to Dr. Forestier the compression of the spinal nerve and of all the nearby tissues within the duct is the origin of severe rachialgiae and even of peripheral disorders, such as the sciaticas, accompanied by contracture of the deep spinal muscles. The fatty hypertrophy does not appear as a mere aspect of a pathological processus without any casual action upon the symptoms of the disease; instead, it is this hypertrophy which is the origin of the syndrome, and the hypothesis of such a pathogenesis is verified by the results of operative intervention. In many countries sciaticas and lumbagos have led the physicians a merry chase, and treatises and memoirs on these subjects, not forgetting of course the sacro-iliac lesions, are numbered by the thousands; yet it cannot be said that a general understanding has been reached, whether on etiology or nosology, and far less on specific methods of treatment. In cases of chronic funicular sciaticas, rebellious to usual therapeutic means, physical, radiotherapic, or others, Dr. Forestier advocates two modes of action, one of which consists in the injection of lipiodol into the epidural space, a practice somewhat in vogue at present in Europe; the other is laminectomy. Several cases are cited in which the opera- All Rights Reserved American Academy of Osteopathy® 130 VERTEBRAL MECHANICS-GUY tion promptly relieved the pains and all other clin- ical elements select from the endomedium, the ical symptoms, so that a complete cure ensued ; the blood, the divers substances with which their chemflexibility of the spine was restored to normal and ical constitution makes them apt to combine; most its solidity gave no fears.

Edema..-Mechanism of Production.-Elimina- tion .-The multiplicity of delicate organs within the vertebral canals is fraught with peril of numerous local and distant derangements, all of which however have to do with circulation, that is, with life and functions of tissues. The one disturbance commonly found at the start is edema. It may be caused by hyperemia or by anemia; through intravascular or extravascular. pressure ; through disturbed vascular innervation; through blood or lymphatic vascular obstruction. The extant serosity is not a mere transudation of blood or lymph serum, as proven by numerous chemical analyses. When a vein is obliterated and the blood does not find in collateral veins sufficient passage to return freely to the heart, edema develops within the organic territory drained by that vein. This was established by the experiments of Lower as early as 1680, and later by many others in such a way as to fix beyond doubt the relation existing between the edema and the vascular lesion. The facts are naturally explained by the increase in blood pressure below the obliteration and by the exudation as immediate consequence. Edema occurs also when the arterioles and capillaries of a region are obstructed; the blood in the continuing veins ceasing to be drawn towards the heart by the vis a tergo loses its pressure, and there is a retrograde flow from neighboring veins towards the capillaries, which increases the pressure somewhat, but mainly contributes to stasis followed by serous transudation (collateral edema). An identical phenomenon is observed in some cases of main arterial obliteration. the consideration of reflex action, stating that: Prolonged irritation of sensory nerves often produces a lasting reflex dilatation of the vessels, with edema as a consequence. Vulpian, who held at first for a casual disturbance of the capillary circulation conditioning “collateral capillary fluxion,” and also, as before stated, the venous “retrograde fluxion,” suggested another mechanism. He thought that centripetal irritations due to nerve lesions were reflexed, not to the arteries, but exclusively to the smooth muscles of the veins and venules; these vessels becoming constricted would interfere with the return circulation, pressure would increase in the capillaries and serous transudation would consequently ensue. This interpretation quite naturally leads us to a most interesting consideration of the vasomotor processus which, even up to date, is so unconvincingly expounded in textbooks, and to what we believe is a novel presentation of the subject. In the first place we were taught that circulation is regulated by the action of nerves; some of these conveyed stimuli to the smooth muscles in the arterial sheaths ; the muscles contracted ; the vessels constricted; the flow of blood was then restricted. The sequence of events was faultlessly logical, easily understood, and the notion of vasoconstrictor nerves unreservedly accepted. The return to normal flow was readily explained by the relaxation of the muscles and the simultaneous expansion of the sheaths through their structural resilience. Increase of blood flow through vasoexpansion was naturally assigned, as a matter of course, to the action of vasodilator nerves and muscles. But here was a great stumbling block; whereas everywhere in the body muscle antagonism was the rule, as for instance where a. flexor muscle always worked conjointly, and reversedly, with an extensor muscle, here the, dilators could not be found, either within nor outside the sheaths, While the influence of the nervous system and there the question remained, unsolved despite upon the. formation of edema had long been the unremitting efforts of the average physiologists, suspected, it was only in 1869 that Ranvier demon- a set of well intentioned, but often disappointing strated through extensive experimentation that, ex- people who at times build up magnificent struccept in cases of actual rupture of blood vessels, the tures upon hypothetical foundations, which they vasomotors were the main instrumental factors. seem to take special delight in uprooting, to the The modus operandi became clear later on when great dismay of the confiding student.

Vertebral Mechanics ALBERT E . G U Y, D . O . Paris PART VI (Continued from January issue) of vital importance ,to the subject failed to receive the due consideration which would have led directly to the required solution of the problem. The first is that venous sheaths contain muscle fibers, not to the same extent as the arteries, to be sure; that these muscles must be there for a purpose, undoubtedly vasoconstriction ; that wherever there is a muscle fiber there are always at least two kinds of nerves concerned, sensory or detector, and motor. The second point is that whenever vasoexpansion is called for, it is not intended for the All Rights Reserved American Academy of Osteopathy® 134 VERTEBRAL MECHANICS-GUY nerve purpose of flushing the blood vessels, but rather to carry a larger blood supply to a territory served by a given capillary network, either in need of it, or accidentally compelled to receive it willy nilly. If instead of simple flushing we were to deal with collateral circulation, then of course the resistance to the flow must be reduced, and consequently the arterial and venous muscle fibers completely relaxed so as to provide through vasoexpansion. the best possible area of passage. But to suit extra supply to the territory the arterial muscles must be completely relaxed, while the venous muscles are contracted; hence the venous passage is constricted, the pressure increases in the artery, the arteriole and the arterial capillaries; they become distended and the enlarged superficial area of the capillaries permits of greater osmotic action which, together with the greater internal pressure, insure the penetration of the extra volume of blood elements into the surrounding tissues. Normally the tissues must soon be drained of the fluid and waste accumulation, then the process is reversed, the venous muscles are relaxed while the arterial ones may be contracted, the blood supply is reduced., the intratissular pressure added to the vis a tergo, which now has free rein, insure penetration into the venous capillaries and thus restore the return circulation to normal. In principle that is all there is to the operative mechanism of capillary circulation; it suffices fully in the three main conditions ranging from plethora to normal,, then to depletion. In normal flow the sheaths are maintained in incessant state of vibration, first through the pulse, and then through rapid alternate contraction and relaxation of the muscle fibers under nerve control ; this is essential in all organs of regulation which may be called upon to respond instantaneously to a demand for variations in range of operation; we may observe the reduction to practice of this principle is high speed machinery, steam turbines for instance, where the governor is kept constantly oscillating so as to avoid sluggishness in starting its work of control of the uniformity of speed, when the latter is threatened. by sudden changes in power requirements. In plethora we have in sequence, relaxation of arterial muscles ; contraction of venous muscles ; venous constriction ; increased arterial flow ; fluid surge in the capillaries ; increase of pressure in the latter, then in the arterioles; consequent distension of the artcerial vessels, whence maximum delivery of �blood. Should this condition be maintained through some cause affecting the nerve control, hyperemia would obtain, followed by infiltration of the tissues ; insufficient absorption through the usual connective tissue pathways would result �in congestion, with transformation of plasma into serosity, thus establishing edema. Any stagnant fluid in the body undergoes some form of decomposition, with attendant production of acidity, (lactic acid particularly), and release of CO,. For normal function muscle fibers require an alkaline medium; it is well known that muscle contraction is affected when this medium is modified, even by an acid so diluted as not to chemically alter the tissues. (Claude Bernard, 1859.) Acidity is decidedly irritant to the nerves, and particularly so Consequently we realize that a local edematous condition is bound to affect the musculature of the blood vessels, the nerve endings in the sheaths, in the territory served by the capillary network, all of which will further aggravate the circulatory disorders and, through contiguity or by reflex action, cause disturbance in near or distant parts. The circulation which at first was accelerated by arterial expansion may become so reduced as to propoke stasis, fibrination, coagulation of blood in the network, which leads directly to inflammation processus ; effectively, the region in which obliteration occurs is always recognized as the primary seat of inflammation and of eventual suppuration. In vaso depletion, or diminution of the circulation in a network territory, there may be simultaneous constriction of the arteriole and the venule, or constriction of the arteriole only, with the venule at first unaffected. The maintenance of such a condition would obviously produce anemia, lack of nourishment, hence wasting of the territorial tissues and of the capillaries themselves. It is unnecessary to speculate at length on this aspect of the question; we may remark, however, that the local disorders would require appreciable time to develop into serious pathology, while their effects on the nerve terminals would probably be less consequential for distant organs, through reflex action, except of course when concerning highly specialized structures, than would those resulting from severe hyperemia. As to elimination, we have already mentioned that it takes place through the agency of the vessels within the connective tissues, that is the veins and the lymphatics. All the above considerations apply generally to capillary circulation through the organism, but we must recognize now that they apply also, and with still greater force, to the delicate structures located within the vertebral canals, because of their most intensive vascularization, and that the development of edematous conditions in their midst is bound to produce distant effects far surpassing mere local tissular disorders. One point of primary importance for us is the determination of the process through which distant disturbances may affect the cord structure, starting therein reflexes which may be influential in the production of what we recognize as lesions. The existence of these is revealed through palpation, in the form of contractures, of vertebral displacements, of painful areas, of disordered function, of impaired mobility, etc. We may then attempt to delineate schematically the mechanism of the transmission of impulses which sets into action the operative mechanism of capillary circulation described above. Mechanism of Capillary Circulation.-For the purpose of discussion we may conceive a vascular system as sketched in figure 30, in which art artery divides into a number of branches, or arterioles ; each becoming an arterial capillary out of which nutrient materials pass into the surrounding tissues ; immediately following comes the venous capillary into which are discharged CO2, waste matter and fluid residues from these tissues ; this continues into a venule which in company with many others combine to form the collecting vein, a branch of the return circulation system; we to the sensory nerves. All Rights Reserved American Academy of Osteopathy® VERTEBRAL MECHANICS-GUY assume that a certain territory is served by one given capillary network, which provides its nutrition and drainage. The sheaths of the artery, arterioles, venules and vein have muscle fibers; consequently each of these fibers is under nerve control, and evidently since each kind of vessel has a function of its own, each must have specific control. The condition and wants of the territory are detected by the terminal organs of sensory nerve filaments anastomosing into a branch S which, after passing through a local ganglion, is referred finally to the posterior root and to the spinal cord. From the gangion issue two motor nerve branches A and B, with terminals distributing to the arteriole and venule muscles. It seems plausible that for routine function the impressions gathered by the sensory terminals are transmitted to a master cell C in the ganglion where, according to their intensities, they cause impulses to be generated, which are directed through A and B to the muscles. It follows that, depending on circumstances, A may be inhibited, thus relaxing the muscles and allowing the arterioles to expand while simultaneously B is actioned and the venules contracted ; or on the contrary B may be inhibited and A actioned ; or again the two may together be actioned or inhibited. The mechanism of the discerning and selective activity of cell C has not yet been exposed; however it must be very simple, and possibly is a mere function of the intensity of sensory impressions; the reflex is formed by S and its terminals, the cell C and the terminals of A and B amply suffice for the ordinary needs of the territory. Stronger impressions would require stronger action, in which case the nerve filaments D and E may convey impulses to the artery and vein, causing their expansion or constriction in the same way as for the smaller vessels. Over intense impressions may cause dysfunction of cell C, and be conveyed by Ss to the sympathetic ganglion, and then referred to the cord and to the ideation centers, where pain or disorder sensation may be evolved. In response motor stimuli may be sent by reflex action from these centers, to the cord segment, the sympathetic ganglion, thence to the local ganglion and probably to adjoining ones. It is most certain, judging from clinical and experimental observations, that the over intense impressions reaching the sympathetic ganglion will affect other sensory endings there, and that the whole territory served by the regional sensory nerve will be affected, thus in turn causing dysfunction in parts distant from the original disturbed area. Once we admit the plausibility of this reasoning we readily understand the reverse process, that is, the effects of disturbance within distant organs, peripheral parts, cerebral or medullar centers (emotional, etc.), extending distally to elemental vascular systems, causing plethora or depletion, whence blushing or pallor, sudor or dryness, pilus erection, warmth or chill, contracture or flabbiness, pain sensations, etc. As a practical illustration-or diversion-let us consider the case of a patient diagnosed as acute pericarditis, in accordance with symptoms of remittent fecer, distress, nausea, vomiting, disturbed cardiac action, precordial tenderness and *pain, slight dry cough. If we know the cause we might feel more at ease. However, we may prescribe as 135 usual: absolute rest in bed, quiet, milk diet, either hot or ice applications to the precordium, with morphine or atrophine to reduce the pain. or, if we are merely an osteopath we proceed with careful palpation while intensively cerebrating in this manner: precordial pains are impressions conveyed by sensory nerves; such nerves on the naterior aspect of the pericardium are terminal branches of the right phrenic nerve, although the left may contribute ; the phrenic nerve receives its principle root from the fourth cervical, and secondary ones from the third and fifth cervicals.-Palpation of the neck reveals an extensive lesioned area involving mainly the third, fourth, fifth and sixth vertebra ; in addition the neck and shoulder muscles are found contractured, particularly on the right side; thumb pressure applied on a spot about two-thirds down the scapula, on the bisectrix of the lower angle, provokes an excruciating pain, more pronounced on the right side ; the right shoulder is very tender; painful irradiations extend in the arm to the level of the elbow; the upper dorsal area close to the spine is very tender. This being an acute case, and there being no prima facie evidence of infection, what is the verdict? The osteopath then suggests to the patient that his trouble may be the result of exposure to cold, particularly affecting the shoulder and upper back muscles on the right side ; this, after a little reflection, is admitted to be the case: automobile ride after a tramp through the country, exposure to direct and back draft. Upon what bases was this diagnosis established? The case was acute; the cervical lesions were of recent origin ; the vast extent of the body contracted, in pain, or even tender, s u g g e s t e d regional irritation of sensory nerves; cold exposure could produce all that. The pain symptom in the infraspinous fossa of the scapula is very presious; invariably it indicates lesions of the fourth and fifth cervicals; it affects the infrascapular nerve, a branch from the suprascapular, formed mainly from the 5 C. root. The pains in the shoulder were due to irritation of the cutaneous branches of the supraclavicular N. (4, 5, 6 C), and of the axillary N. (5, 6 C) ; the pain in the arm was due to irritation of the musculocutaneous N. (5, 6 C), and of the internal branch of the radial N. The disturbed cardiac function could be ascribed in part to the action of the rami communicantes issuing from the 5 and 6 C roots, which join the middle cervical ganglion; from the latter, and through the sympathetic chain, connections are established extending to the cardiac plexuses. The other symptoms could be traced in similar fashion. The course of treatments consisted in careful but most thorough relaxation of the soft tissues, and correction of the cervical lesions. This was a n actual case. The conclusions seem obvious. All Rights Reserved American Academy of Osteopathy® 136 VERTEBRAL MECHANICS--GUY Vertebral Mechanics ALBERT E. GU Y, D.O. Paris PART VII To&cc&.-Just as in our school days, after we became initiated to the mysteries of elementary algelx-a, we delighted in tackling problems as they presented themselves here and there, and thus became proficient in practice, so it is also with us in the field we have chosen, and we find great and profitable pleasure in analyzing not only the cases we handle daily, but principally those that are brought to our attention by more matured and experienced practitioners. Some of our most difficult cases usually come to us after everything else has been tried, and osteopathy is called upon as a last resort. Therefore, excusably at that, we start with some trepidation, in spite of our faith and our methods, and as we progress and ultimately achieve success, we cannot help wondering in awe at the potency of the treatments. This peculiar feeling is engendered from the fact that outside our profession we must not expect credit for the success of our efforts, as it is well nigh incredible for other schools that mere manipulations and simple spinal corrections could accomplish that which balked most conscientious adepts of widely recognized medical means. We can overcome this feeling, not by compiling extensive statistics of cases, unconvincing to the adamant state of mind of the outsiders, but, individually, by minutely analyzing the cases as they come to our notice ; so that we may more and more clearly visualize the pathology involved, study the various causes of disorder, devise the most likely means to overcome these latter, and finally observe the effects of these means and catalog them for future reference. We cannot afford to remain satisfied with what ordinary routine treatment can accomplish; we must be constantly guided by the thought that osteopathy is bigger than any osteopath, bigger even than its founder, Dr. Still, and indeed the Old Doctor was ever ready to recognize that fact; and that imposes upon us the: task, most pleasurable after all, of ceaselessly “living with our cases,” somewhat in the manner suggested above. A most interesting case is recently called to our attention by Dr. Charles Hazzard, who had successfully treated it, and who presented a detailed review of it before the Technic Section, Annual A.O.A. Session at Philadelphia It was one of forceps delivery. After a few weeks, in which it appeared to be normal, the child gradually, over a period of two months, developed a condition marked by wryneck, cross eye, oscillations of the eyeballs, spasms of the spinal muscles, and severe convulsions. An anomalous feature of the case was the occurrence of a marked periodic bulging of the fontanelles and of the parietal bones. Lumbar puncture had been performed twice, but with the production of no cerebrospinal fluid, only a little blood. As a problem, the primary or cardinal points are: (1) forceps. delivery ; (2) proven absence of congenital infection ; (3) robust constitution which kept the child in apparently normal condition for a few weeks after birth; (4) gradual development of the symptoms enumerated above. The question is to trace the origins of this development. �The Journal, Sept. 1930, p. 33 . Wryneck or torticollis is an affection characterized by severe contracture of the cervical muscles, accompanied at first by excruciating pain upon the least movement of the head and neck. The head is maintained inclined to one side and the cervical vertebra are consequently held in lateral bending position, with their convexity on the opposite side of the head. The first muscle affected is usually the sternocleidomastoideus; then follow the scaleni, the splenius, the trapezius, and to a certain extent the platysma and the cervical fascia ; but such a sequence is far from proven, and it must be adjusted to suit the true origins of the disorder. In the textbooks the causes are attributed to cold exposure, to overexertion, to overrotation of the head and neck, to trauma, to injury at birth, to infection, all of which has been demonstrated, Some authors, however, have gone a long way past the goal in stating that: A few cases of acute torticol- lis are caused by some of the deep muscular fibers becoming caught around a process of a vertebra:. It is greatly to be regretted that such an anatomical stunt has never been described with details and illustrations worthy of the most extraordinary phenomenon. Whatever may be the original cause, one thing is certain, and that is the muscular contracture characterizing the disorder. Contracture is a state of contraction of an skeletal muscle which is beyond the power of voluntary control. Muscle substance possesses the property of changing form under the influence of certain stimuli, but it cannot do so spontaneously, for living matter cannot any more than the inanimate, impart motion to itself, therefore the stimuli are generated by extraneous means and conveyed to the muscle cells by the nerves. As contracture is always an abnormal condition, this elementary reasoning leads us to admit the existence of a disturbing factor affecting the nerves themselves, or their roots, or the cord, and accordingly, producing specific symptoms. Although we know that the head was misshapen by the forceps, there is no direct evidence of external injury to the cervical parts; if the spinal accessory nerve had been injured by pressure directly at its exit through the jugular foramen, immediate+ symptoms of disorder would have been manifest. It is then plausible to admit that the lesions affecting some of the numerous organs within the vertebral canal were produced by pulling or twisting during the expulsion process. Such lesions may concern the yellow ligaments, the posterior common ligament, the periosteum, the articular capsules,, but not necessarily the meningeal membrane directly. The repair process which began at once involved some degree of hemorrhage, extravasations, edema,. phlegmasia (always present, as we have seen in previous articles, whenever any tissue undergoes repair), all of which would tend to establish a regional compression within the canal of sufficient intensity and extent as to interfere with the downward circulation of the cerebrospinal fluid. This would suffice to account for the fact that two lumbar punctures failed to release any fluid, except a little blood, and to relieve the intracranial pressure. If we agree upon such a location of the lesion we can easily understand the progressive development of the pathology, which was aided undoubtedly by the effects of the intracranial conditions upon various important centers. The repair depended mainly upon extensive nutrition and elimination, but both processes became increasingly interfered with, with the result that a state of All Rights Reserved American Academy of Osteopathy® VERTEBRAL .

Some of the patients actually feel All Rights Reserved American Academy of Osteopathy® 138 VERTEBRAL MECHANICS-GUY slighted; they had come prepared to sustain an extensive siege of operations, and it is only after the manifestation of the beneficial results that they become reconciled, although left in lingering doubt because of a complete lack of understanding of the modus operandum. Some eighty years ago-the exact date is not at hand just at present-a celebrated French doctor, in charge of one of the largest hospitals in Paris, performed the then most surprising feat of reducing a fleshy tumor simply by digital kneading of the mass of tissue involved; it is said that such a treatment was quite awe inspiring his staff of internes who had always understood that in such a case the usual application of heat and appropriate unguents was the sole method to be considered. The attending success was such that a detailed report was duly presented to the Academy. It was explained that the kneading relaxed the tension of the tissues, and forced the drainage of the pathological fluids through the veins and the connective tissue networks from which they were absorbed by the lymphatic vessels. Here of course the accent is most appropriately placed upon kneading. Now in case of cervical lesions such as we have considered above, what are we dealing with? External contractures are easily amenable to manipulation, but what are the conditions within the vertebral canal? No muscles are involved, but the elastic ligaments are in trouble ; they may have been sprained, torn, in which case the periosteum is certainly affected ; or they may have been affected by contact with the internal parts disordered by hemorrhagic and inflammatory conditions. Normal ligamentous tissue is highly resistent throughout its physiological performances, but when in pathology its sensitiveness is exacerbated, with the interesting result that it may become contractured, just the same as a skeletal muscle. As we have seen with the ossification processes, any tissue undergoing repair is to some extent in a phlegmasial condition involving some degree of contraction ; but this contraction does not usually interfere with the repair; on the contrary, when contracture sets in, it maintains a state of congestion, with stasis of both nutrient and the waste fluids, and hence production of acidity and lowering of regional alkalinity, highly irritative to the tissues and the nerves, and greatly obstructive to the repair process. Leaving aside the subjects with hypermobile articulations, often, and wrongly so, selected for demonstrative proof of the skill of the instructor’ in technic, the average osteopathic treatment consists in overcoming the muscular contracture, with consequent and immediate drainage of the external tissues-as proven by the prompt abatement of regional painsthen of mobilizing the spinal articulations. This mobilization is equivalent in fact to kneading the various ligaments connecting each pair of vertebrae. But complete relaxation of an intervertebral articulation cannot be obtained until the yellow ligaments are stretched to an extent sufficient to overcome their contracture. With the patient well positioned, the final effect is applied with a quick motion, usually, although that is not always physiologically required, and a popping noise is produced, scaring the patient and gratifying the operator. Apophyseal articulations were not intended by nature to be separated. We have never observed a normal individual, or an animal, going about usual activities, and even when performing feats of strength or agility, emitting vertebral creakings or poppings. We know of course the noises attendant to arthritic conditions, but then the articular surfaces are always affected by disease. The apophyseal articulations are intended for guidance and control of the spinal movements. When they are forced apart the separation is of extremely short duration ; it seems as if the guardian ligamentous structures had been taken by ruse, by surprise, as if they thought that the preliminary positioning of the body, with the customary objurgations of the osteopath: “Please relax, breathe deeply,” etc., meant only a call for an extra physical effort, and they complacently relaxed their own vigilance. Taking a mean advantage of this misplaced confidence the operator senses the opportune moment and quickly applies the fatal-eventually beneficial-thrust, and there is separation. Realizing instantly their lapse in vigilance the controlling ligaments contract at once and, aided in that by the deep muscles, bring back forcibly the articular facets into contact; the result is a shock, with -a popping noise, bone against: bone, within a mass of flesh. The shock is both physical, or material, and physiological ; it sets up a reaction, a sort of shaking up of all the interested tissues, and for hours afterwards there is a period of readjustment affecting various organs within the intravertebral canals. There is new activity, new life, set up, speeding elimination of waste or sluggish fluids, naturally following which the arterial blood supply overcomes the detrimental hypo-alkalinity and thus restores the normal functioning of the nerves. During this period, and for several hours after the correction is made, it is not possible to repeat the same performance with the expectation of eliciting the popping noises. This is of course readily demonstrable by cracking the phalangeal articulations of one hand ; we all know that some time must elapse before a repetition is obtained, unless one should have specialized in this sort of amusement, or mania. Even in the simple experiment of cracking one’s fingers, the observer may derive valuable information applicable to the study of vertebral technic; thus, immediately following the cracking one experiences a feeling of weakness in the joint, which is followed by the sensing of a gradual readjustment. Here we deal mainly with an articulation, also not intended by nature to be disturbed, whereas with the spinal manipulations, the object is not at all to elicit the spectacular popping noises for the mere purpose of edification of those not versed in the art. It should always be made clear that the popping is a mere incidental, and not at all a curative means. The sound may be of value to the operator as a proof that, after due soft tissue preparation and mobilizing work on the spine, the articulations are at last free to the extent of disengagement, and at that, for the time being. The observed fact that a period of readjustment invariably follows a spinal correction leads us to ponder over the wisdom of our leader, the Old Doctor, who tersely advised the operator to find the lesion, to correct it, and to leave it alone. Too often repeated treatments-each being so powerful in its effects-may interfere with the readjustment by keeping up a condition of hyperactivity in tissues and structures actually in need of repose. The acquisition of practical experience must never be done at the physical expense of the patients, and the Italian say- All Rights Reserved American Academy of Osteopathy® l VERTEBRAL MECHANICS-GUY 139 cord, the roots or the meninges, or indirectly through ing : che va piano va sano, holds good here as in many other fields. causes obtaining within the vertebral canals and disMany years ago, while visiting regularly for a turbing by contact, adherence, phlegmasia, etc., the time at a large New York hospital, I had occasion delicate nervous structure of the region. one day to ride in the elevator with a passenger of According to reports emanating from the most Ethiopian hue.

That of course is a little vague, but we can make the meaning more precise by inveigling the meningeal membranes and to some extent portions of the cord itself. When a vertebral displacement occurs it is invariably due to the combined action of muscles and ligaments, which obey exclusively to nerve control ; recurrence of the lesion may indicate a weakening the other parts involved, and perhaps some impairment of nerve control; but with the periodic recurrence while the external parts are felt in fair order, nerve impairment is certainly indicated, either directly at the source, that is in the All Rights Reserved American Academy of Osteopathy® OUR OSTEOPATHIC ACTION Quintus L.

The same definition may be logically applied to Osteopathic Action which then, is described as "A system of therapeutics based on the theory that diseases arise chiefly from the displacement of bones with resultant pressure on nerves and blood vessels and can be remedied by manipulation of the parts". On reflection, therefore, it becomes apparent that when Osteopathic Action deviates from these self established frontiers, it invades foreign territory. Our science and opinions vary in accordance with our interpretations of the teaching and application of the osteopathic principle in relation to our concept of the lesion. The basic method of applying Osteopathy consists mainly in the manipulation of joints and tissue. (From page 22 Philosophy of Osteopathy by Dr. Still) "If we wish to be governed by reason, we must take a position that is founded on truth and be capable of presenting facts, to prove the validity of all truths we present. A truth is only a hopeful supposition if it is not supported by results". I believe this type thinking expresses the very fibre of the Academy membership in relation to the profession. We have seen much action in all fields of the healing arts and where we, as Osteopaths, used to think in words, we now think in accomplishment. Any science progresses by using the dead and dying ideas of today as stepping stones for tomorrow. In our future Academy Osteopathic Action, as co-owners of the profession, we must pledge a new devotion to an organization welded together by its individual members working for a principle with -some - ob-. jective. We, of the Academy, are familiar with our professions ability to accept ideas and the formal demands made by our executive bodies in these various fields that expect, or hope, to have as a basic objective, the recovery of private rights, osteopathically speaking. The A.O.A. should be in its entirety what we as a special group represent. People create their own lack of opportunities. Osteopathy has been made great by its followers who used it. My role, or subject, Our Osteopathic Action, is not that of Mark Hopkins on one end of the log, but of Socrates on one end of a question. My function is to get up steam in the cranial boilers of the students and fellows of osteopathy and our leaders for future use. A student does not stumble on the right principle or answers to Osteopathic Action; the real teacher, by challenging him, forces him to think the question through, osteopathically. I have always considered it an honor to be a pioneer in the developing of Osteopathy. Aside from the financial phase of practice there is what I'd call a "psychic income" that equals the intelligent appreciation of the soul beyond life in the realm of osteopathic service. A "psychic income" which is that inner satisfaction of serving and succeeding - and in the gratitude and confidence of those whom we serve where others have failed. I have practiced and studied Osteopathy for thirty three years because I believe in it. I hope the Academy may have a great influence in charting the future course of Osteopathy for I feel sincerely that it is the Academy of Applied Osteopathy upon whose shoulders rests the future of our profession. There are some fine new ideas now being considered by the Academy officers for future stepping stones for advancement. The difficulties encountered in making progress can be eliminated to a great extent, by cooperative action of the membership. The problem is in knowing what to do next. At this point, knowing what to do next, let us ask and try to answer a few modern questions from the Academy's angle, including some ancient facts. Why don't we stick to Osteopathy? 141 All Rights Reserved American Academy of Osteopathy® 142 Because there are those who wish to revolutionize our basic principles by replacing our system of practice through the implementation of medical theories which, to say the least, is alien dogma. It is reform, sincere but presents the question again on the "ten fingered osteopath" versus the "hypodermic medical osteopath". Each has the right of opinion. The public, the profession and the schools are the agencies which should determine our policy, not a competitive profession. I'll give you this example of the question: At the St. Louis World's Fair in 1904 in St. Louis, Doctors Harry Still, Herman Goetz, George Laughlin, Hullet, Clark, Young and others put on a six weeks post graduate course which according to the records found in my father's papers, was a big success. The whole theme was developing the structural cause for disease on osteopathic fundamentals. At the Kansas City Child Health Clinic in 1948, one speaker mentioned the osteopathic idea a few times in the three days - another passed out mimeographed sheets giving the dosage shots, hypodermic regularity, etc. That's forty four years of progress for Osteopathy. Why do we argue the point? The only cure for disease is found in the natural function of nature. The considering of the germ theory, anti-toxin, vaccines, chemical drugs and surgery represent a true form of medical treatment, and we should know about it for diagnosis of disease. Regardless of classification, all branches have to fall back on nature for the ultimate cure and we have let go of that natural principle upon which Osteopathy was built; that all disease is functional from the start. An example of what I mean in my special field, let us say the handling of a congenital hip - it is reduced osteopathically and then nature builds up the deeper socket. The cure of the lesion is not to be found at the corner drug store. How long will Osteopathy live? There are several ways in which we can rule ourselves out of the opportunity to serve humanity. First, of course, is the mimicking of the M.D. - by trading with them and the true sell out to them, i.e., the Homeopath and Eclectic. (2) When we quit teaching and using Osteopathy it will die. (3) The separation of our profession into two groups, each suspicious of the integrity of the other, is not conducive to long life, and pertinent facts should be offered for some future plan. (4) Are you prepared or do you care to throw criticism at some of the experts who offer advice on our technical problems and nothing acceptable for educational purposes? The public has demonstrated one positive fact which extends our life line - that it wants Osteopathy and will support it. I confess a state of confusion exists in the therapeutic balance between the practitioners of Medicine and Osteopathy, but the intelligent lay public is open minded and concerned about our osteopathic future. How can we compete in business? The true situation is, we have six(6) approved or Class A rated Colleges as compared to sixty nine (69) Class A Medical Col1eges. We resort to Progress Fund or passing the hat for our schools, whereas the medical colleges are endowed up into the millions, or State supported. Both have their troubles with the financial problem and their administration. These sixty nine Class A Medical Schools limit the freshman enrollment to an average of about sixty five (65) per year, to say nothing of the lower rated schools. Our six Class A Schools limit to say one hundred (100), and even on that basis we can get a real picture of future graduated power in the field of practice, influence and financing ability. Can we meet the program financially? In analyzing this phase of the matter we must think terms of dollars and policy, as it now exists. First, we cannot tax and spend over our income as individuals or as a profession, and that's final insofar as the dollar problem is concerned. Financially, we cannot mimic the medical profession nor hope for State and Federal support on a pro ratio basis. Also, we have, I believe, pretty well milked our profession on the pass the hat or Progress Fund. We cannot waste our limited resources or promote any unsound business programs in the future. From experience, I know what it takes in effort, profit and loss, etc., to overcome problems that arise under the broad coverage of a policy in business and the same is applicable to a profession good and bad times reflect their influence in your cash intake and output and it is always due to some policy action. Now, professionally, our National Association has in recent years adopted a broad policy All Rights Reserved American Academy of Osteopathy® 4 of "un-restriction" - no limited. privileges laws, teaching, etc., and followed the standards of the medical profession. Since these changes in the A.O.A., the colleges and the requirements, the osteopathic aspect has likewise changed. Further, we have gone, like our Federal Government, into a big show policy, minus the finances, colleges with more employees than students, heavy obligations to pay over a long period of time, and poor business administration. It all adds up to this, we cannot exist on such a business basis or policy. Upon whom does the burden fall? It is most obvious to me that some changes are needed in our setup - administrative, financial, colleges and future policies in general. The future security of any business or profession depends on youth development for modified standardization in that particular field or specialized commodity which is being presented to the public. We can well afford to spend some time in developing young men to take, over some of our problems. We can find Osteo; paths who are qualified to function in any specialized field, men willing to give a genuine service to Osteopathy. We have had, and we are no exception, both good and bad leadership. Now the time has arrived when we in the profession must find individuals who are willing to serve without profit. We must get interested in the re-establishing of the fine osteopathic basic principle on a sound business basis. It is perfectly clear, to me, that educational stability ranks the number one problem in the future of Osteopathy. Our colleges either do not teach technique or recent graduates will not use it in the field. I believe, if it is possible, that the Academy's future Osteopathic Action should be directed toward improving the teaching or real Osteopathy in our colleges. To summarize this personal idea, I quote Wm. P. Talley - "Education is concerned with action and life - the life of reason. Its goal is a disciplined person, applying and directing his knowledge and his powers". Our supplement to this idea can be in the field of research. Our goal and hope rests in our individual abilities being placed at the disposalof our Academy leaders to form a cooperating, understanding body, thinking clearly and frequently on Osteopathic problems. On the United States Archives Build- 143 ing in Washington, D.C., there is this motto - "The Past is Prologue". How frequently in the past years have I thought in the terms of that motto as it applies to our problems, progress and actions. . If, and we of the Academy do, appreciate the Science of Osteopathy, we must exchange ideas, forget jealousies, cooperate with the colleges, executive national departments, and finish what we have started for our own future security. Let us not be discouraged by the natural marked differences of opinion concerning the proper solution of the multiple problems involved in such a step forward. First plans are never acceptable to all concerned, but they form a foundation for negotiations and adjustments for greater development. We have reached a point of development that now calls for positive action on the part of the Academy members and officers. The matter of faith and duty is paramount in our professional lives. We have faith and doubt not the pathology of the lesion, Dr. Still's works, and the cause and effect basic principles established by Dr. Burns. All these physiological osteopathic action lesions were covered by Dr. C. C. Reid who gave four subheads under Action from the anatomical side - (1) the mind; (2) energy; (3) chemistry and (4) mechanics. His talk was full of real appreciation of Osteopathys trustworthiness in handling the question and he emphasized the art of handling the four functions, osteopathically. Dr. Still, the philosopher, expressed his faith in Osteopathy by saying - "Intelligence will accomplish our great objective - world recognition - and the future will dwarf the past in the collective talents of my followers". When we study our science and practice it, we eliminate doubt and establish faith in our field. We must work to make it better and expand our facilities. Osteopathy must be taught - it is,-not mechanical. It must be demonstrated - it is not reading matter. It proves itself. It has appeal and alleviates suffering. People who use Osteopathy are high type, and loyal to the principles of the osteopathic profession. We have a specific field in which to operate that does not exist in the field of medicine. It makes no difference about the terminology such as "physical medicine", "manipulative therapy", etc., so long as this high All Rights Reserved American Academy of Osteopathy® 144 type clientele continues to appreciate the intelligent presentation of osteopathic service. To be recognized by some twenty insurance companies as an authority on partial and total disability in their problem c&es - to have Circuit Court cases stopped by a Judge to have the case examined, reported and settled the next morning on osteopathic written testimony - to investigate and prosecute and dissolve "Medical Racket Rings" in industrial fields - to be consulted by medical authorities on osteopathic matters, City, State and National to be recognized and appreciated as an Osteopath establishes with me, a greater confidence in our future program. This program must provide a strong, tangible group of statistics based on specific Osteopathy in all fields of research. Such issues should be of utmost interest to us all. We must demonstrate a willingness to reinforce words with action against any who oppose our belief and work in behalf of Osteopathy. We must not indulge in petty politics nor the usual lazy legislative channels of permitted acceptance or we will be failing miserably to comprehend the memberships demand that something be done NOW about saving Osteopathy. Let's keep future educational plans as the backbone for the expansion of ideas on the lessons we have learned and offer onlyconstructive business and professional advice to our administrators. Present the individual problems for analysis to the proper committee knowing that Same will be analyzed, perhaps benefit others, and prevent useless issues arising in the administration of Academy affairs. With our City, State and National Official Organizations functioning under "rules and regulations", our colleges operating under standard requirements, we can function as the third reality. This idea of Newman's is particularly applicable today, for the profession is (osteopathically speaking) in such a state of chaos that we are swaying between total destruction and a new era in civilization. The uneducated or partly educated individual is likely to become frightened or influenced by the opinions of others and thereby rush to a hasty and unintelligent conclusion. On these last two problems, an osteopath must have considerable strength of mind and common sense to overcome quick emotion. Perhaps if we had more such men in the world today we would not be faced with such a black future, and the profession and the nations could be thinking of prosperity instead of war. Dr. A. T. Still faced our present problems over a half century ago almost alone, and never gave up hope. I believe today in his many proved convictions and am not alarmed over our future. Dr. Still had laws of living governing everything he thought and did, osteopathically. Today, I feel as he must have felt that these are laws of the spirit, not of the letter, and have to do with the way we deeply feel and think, osteopathically, with our inward attitude and our outlook toward all that is without. Evidence seems to be accumulating to support the view that we are facing some sort of an adjustment period, professionally. We have been concentrating so intensely on the defensive that we have overlooked the normal forward progress of Osteopathy. Favorable and unfavorable factors can be balanced through mutual combined effort of us all, and we can and will go forward together in establishing Osteopathy on its original foundation. St. Louis, MO. All Rights Reserved American Academy of Osteopathy® DOES THE GROSS MECHANICAL PICTURE STOP AT THE OCCIPITO-ATLANTAL ARTICULATION? Harold I. Magoun, A.B., D.O. The gross mechanical picture or greater lesion complex has heretofore referred to a definite pathogenic syndrome involving the spine and its soft tissues. A rib resection or breast amputation may initiate the structural deviation in the upper spine. More commonly an increased sacral base inclination as from high heels or an off level sacral horizon as from a short leg is fundamentally responsible. Regardless of the etiology, and no matter what pattern that develops, the result is increased tension on the supportive structures, contractured guy-rope muscles and ligamentous articular strain throughout, as well as bony lesions at the areas of greatest stress. The question then arises as to whether this picture stops at the upper end of the spine or whether the strain also involves the cranium and its membrane? To answer intelligently let us first review briefly the fascial and muscular attachments involved. The deep fascia of the neck is our principle concern. It finds its anchorage at many points on the basicranium and also fuses with the periosteum at the superior nuchal line on the occiput, along the superior temporal crest, the mastoid process, the arcus zygomaticus and the inferior margin of the mandible. These layers surround muscles, nerves, vessels and the upper intestinal tube with a complicated system of compartments, which have a vital part in the mechanical functions of the body, since so many important structures are there crowded together in so small a space. Below, the deep cervical fascia is continuous with the mediastinal partitions, pericardial envelope and central tendon of the diaphragm. While most of the cranial bones serve for muscular attachment at some point those pertinent to this discussion are mainly the occiput and temporal. You will recall the attachment of the trapezius; semispinalis capitis; rectus capitis posticus major, minor and lateralis; su- perior oblique and occipitalis bunched between the nuchal lines of the lower occipital squama. You will remember the insertion of the digastric and longus capitis on the mastoid process of the temporal. Note also that the splenius capitis and the Sterno-cleido-mastoid overlap the occipitomastoid suture at their attachments on both bones. There are others which we are not mentioning. However here are fascial and ligamentous and muscular attachments to such vulnerable leverage points as the mastoid process and the supra occiput. The pull may not only be straight down but definitely laterally or anteriorly or posteriorly in addition. Unilateral strains, such as wry neck, either acute or chronic, are common. The average osteopathic practice is full of neck strains causing head symptoms. Many of these muscles arise from the upper ribs and insert into the skull. If the free motion of a rib can be deranged by muscular contracture or strain what of the bone at the other end? Can you consistently say that the physiology is any different in the rib where the muscle originates than in the cranial bone where it inserts? The only difference in motion between rib and cranial bone is one of relativity. The rib, it is true, has an articular cartilage for gross motion and is . held in place by ligaments and muscles. It is equally true that there is an articular pivot between the temporal and occiput that is cartilagenous throughout life. These or any other cranial bones are held in place by soft tissues, consisting of membranes such as the falx and tentorium and the dural envelopes, which extend thru all sutures between the bones. Both rib and crainal bone move with respiration or suffer deranged motion with trauma and mus cle or ligamentous strain. This has been proven beyond a doubt on many hundreds of cases by Dr. Sutherland and his cranial students. 145 All Rights Reserved American Academy of Osteopathy® 146 The old texts on anatomy denied motion at the sacro-iliac. Someday they will acknowledge cranial motion, realizing the difference between the stiff dry-stick effect of the cranium under rigor mortis as contrasted with the live specimen in which the sap still flows. Cranial motion is minute as compared to rib motion but is none the less real. Lesion correction is not manifested by a chug but is a soft slippage of the membranous, cartilagenous or bony element within its dural envelope in relation to its fellow, when the natural motive forces of cerebrospinal fluid fluctuation and membranous pull are put into operation. Dr. Still held a rib in position to exaggerate the lesion, asked the patient to breathe and it corrected itself. Dr. Sutherland holds a cranial bone similarly, directs physiological cooperation by the patient and secures a like result. In so doing he has called our attention to this hitherto unexplored field of osteopathy. Obviously this brief discussion is not meant to imply that influences from below art? the only cause or the chief cause of cranial lesions. The gross 'mechanical picture does not stop at the occipito-atlantal articulation in either - direction. Cranial lesions do occur as the result of spinal imbalance such as short leg or other acute or chronic trauma. Witness a case of tic douloureux (X-ray) relieved by attention to a short leg problem and the secondary cervical lesions but with no cranial treatment. The pain recurred a year later when a new pair of shoes was not altered and promptly subsided with one cervical treatment after the lift was added. In studying such gross mechanical pictures it has been my experience to consistently find the low occiput and the externally rotated temporal occurring on the side of the contractured cervical muscles and fascia as the pulled down by them. What of influences in the reverse direction? The vast majority of cranial lesions are primary to that region, be they incidental to birth trauma or later local disease or injury. It would seem from this fact that there would be a little relation between the lesions of the skull and possible secondary patterns below. There is more dependence than one might think. The cranial picture, in so far as it influences the central nervous system, dictates the structure and function of the entire body. The infant, subjected to a birth injury especially of the condylar parts of the occiput, may have very definite spinal anomalies resulting as the development below is shaped by the abnormality above. Cranial lesions can be the direct cause of spinal lesions. Indeed one of the commonest sources of recurring atlas lesions is to be found in the occipito-mastoid fixations which maintain muscle contraction and, through the malignment of the facets, joint pathology below. Thus it becomes necessary to revise our concept that the greater lesion complex usually proceeds from below upward. Many times the reverse is true. The approach taken in this paper is from the known to the unknown, for those of you who have not studied the cranial concept. It is an attempt to emphasize the fact that Dr. Sutherland has opened a new field for osteopathic endeavors, he has vastly widened our horizon and shown himself to be not only a true disciple of Andrew Taylor Still but also one of the few original thinkers of our day. Cranial osteopathy, sponsored and nurtured by the Academy of Applied Osteopathy, opens a new epoch in the art of healing and is proving that the gross mechanical picture does not stop at the occipito-atlantal articulation. All Rights Reserved American Academy of Osteopathy® THE CRANIO-VERTEBRAL JUNCTION Beryl E. Arbuckle D.O. The crania-vertebral cavity houses the brain and spinal cord. In the Philosophy of osteopathic science which Dr. Still taught his followers, he laid stress upon the importance of the arteries carrying nutriment in an unimpeded fashion to every body fibre and expressed the control of this all important' function in the following manner. "Any variation from perfect health marks a degree of functional derangement in the physiologic department of man. Efforts at restoration from a diseased to a healthy condition should present but one object to the mind and that is to explore minutely and seek the variation from the normal . . . First examine the neck, because of its position and connection with the brain, which is the physiologic source through which nerve force is supplied and suited to the convenience of the heart, to assist in delivering such burdens as it may send forth to nourish and sustain the body . . . You must know what the neck is with all its parts and responsibilities, or you will fail in proportion to your lack of knowledge, not theoretical but practical, which you can only obtain by experience . . . Begin at the head and start at the first bone of the neck, and don't guess, but know that it fits to the skull properly above." The development of the condylar atlantal articulation bears consideration. As early as the eighth week in fetal life the components of the vertebrae are chondrified. Endochondral ossification centres soon appear, a median ossification centre giving rise to the centrum and a centre in each neural process extends dorsally to form the lamina and complete the neural arch. Likewise in the developing skull there is a concentration of mesenchyme about the notochord, which extends as far rostrally as the future dorsum sellae of the sphenoid. This concentration extends more rostrally and soon becomes chondrified forming a supporting floor for the developing brain. At eight weeks there is a confluence of the primordial parts of the chondro-cranium which in the course of development will form separate bones from endochronal ossification centres. It appears that in the course of evolution there become fewer bones in the entire mature structure. Likewise in the growth of the human skeleton from the neonatal period to adult life is there a decrease in the number of bones or portions of bones. At birth the two bones, the occiput and atlas, which bear the articulating facets of the pair of articulations under present consideration, each consist of four parts which develop synchronously from their primordial structures to maturity. The occiput consists of four parts, the basilar, two condylar and the squamous portion, surrounding the foramen magnum. The atlas likewise consists of four parts, two lateral masses and an anterior and posterior arch encircling the dens of the axis, the associated ligaments and the continuation of structures enclosed by the foramen magnum. There is fusion of the lateral masses of the atlas with the posterior arch from the third to fourth year at the time of fusion of the squama with the condylic parts of the occiput. From the seventh to eighth year fusion occurs between the lateral masses and anterior arch of the atlas and between the condylar parts of the occiput and its basilar portion. It is these lines of fusion which pass obliquely through the respective facets of the occipito atlantal articulations, the anterior quarter of each facet being anterior to the line of fusion. Some of the causes of malalignment of the separate parts of the developing atlas and occiput during the fetal and early neonatal stages and consequent maldevelopment of these bones with asymmetry of their articular facets, have been described in previous papers. At this point we shall consider 147 All Rights Reserved American Academy of Osteopathy® 148 the ligaments that enter into this crania vertebral junction. As what might have been the body of the atlas completes the dens of the axis these ligaments constitute the occipito-atlanto-axial group. The articular capsules surround and loosely connect each pair of condylar atlantal facets; There are lateral reinforcements of these capsules known as the lateral ligaments extending obliquely upward and medialward on each side from the base of the transverse process of the atlas to the jugular process of the occipital bone. Each capsule is continuous anteriorly with the anterior atlanto occipital ligament which is broad and dense and connects the anterior margin of the foramen magnum with the superior border of the atlas. This in front is very strongly reinforced between the basilar portion of the occiput and the anterior tubercle of the atlas. The posterior margin of the foramen magnum is connected to the upper border of the arch of the atlas by the posterior atlanto occipital membrane which is broad and thin and incomplete on either side below, helping to form with the groove on the upper anterior aspect of the posterior arch of the atlas, the opening for the vertebral artery. Branches from these form the anterior and posterior arteries of the cord. The vertebral arteries join to form the basilar artery, the branches of which supply the structures in the petrous portion of the temporal bone the pons, medulla and cerebellum and it terminates by bifuricating into the two posterior cerebral arteries. Thus the vertebral arteries contribute to a.11 the choroid plexuses and what might this mean in the event of structural malalignments, stresses and strains or congestion around this area to the formation of the cerebra spinal fluid, "the highest known element in the human body." There are synovial membranes lining these condylar atlantal articulations and also one lining the articulation between the anterior superior part of the odontoid process and the posterior part of the anterior arch of the atlas with which this articulates. The plane of this particular facet is determined by many developmental factors. It varies, being almost vertical with the facet on the anterior aspect of the upper part of the odontoid process or more nearly horizontal with the odontoid facet being almost in a superior position. The articular capsules of the atlanto axial articulations are strengthened medially on the posterior aspect of each, extending from the body of the axis near the base of the odontoid process to the lateral mass of the atlas near the attachment of the transverse ligament. These reinforcements together with those on the lateral aspect of the occipito-atlantal capsules may be visualized as part of the formation of one of the many supporting and strengthening triangles in the construction of man. The transverse ligament of the atlas is a thick strong band retaining the odontoid process of the axis in relation with the anterior arch of the atlas. It is strongly attached on either side to a small tubercle on the medial surface of the lateral mass of the atlas. Superiorly and inferiorly from the middle of this ligament are thinner prolongations attached respectively to the posterior part of the inner aspect of the basilar portion of the occiput anterior to the apical ligament between the dens and the superior part of the anterior rim of the foramen magnum, and to the posterior part of the body of the axis. These vertical portions and the transverse ligament together constitute the cruciate ligament of the atlas. The alar ligaments also anterior to this cruciate ligament and lateral to the apical ligament, extend from either side of the upper part of the odontoid process upward and lateralward to be inserted into rough depressions on the medial side of the occipital condyles. Posterior to the cruciate ligament is the membrana tectoria. This may be considered as the upward prolongation of the posterior longitudinal ligament of the vertebral column. It is firmly attached to the posterior part of the body of theaxis and its very strong bands diverge anteriorly, covering the odontoid process and its ligaments and is attached in a V shaped manner with its apex cephalward to the basilar groove of the occipital bone. Some of its fibres mingle with those of the cranial dura mater. We notice also at the posterior part of the foramen magnum to a lesser extent the intermingling of fibres of the dura mater and those of the posterior occipito atlantal ligament. The cranial dura mater consists as we know of two layers, the inner of All Rights Reserved American Academy of Osteopathy® 149 direction and transmission of forces trawhich presents the reduplications forming the falx cerebri and falx cerebelli, the velling through the skull.

All Rights Reserved American Academy of Osteopathy® THE PROBLEM LOW BACK Alexander F. McWilliams D.O. Every low back case is a potential problem until a diagnosis has been established, after a diagnosis has been established it ceases to be a problem, but frequently judgment and skill is required in caring for same. Even the simple low back case can become a problem, dependent upon the type and frequency of treatment, for instance one of the profession asked me to see a patient whom the Doctor said was going to quit Osteopathy. After seeing the case I advised no further treatment for a week. The patient was symptom free in four days. It was a case of the Doctor wanting to do a special job for a prominent man and treated him every day with the result that nature had no chance to assert itself. The time allotted will permit of only hitting a few of the high spots in a gross way, that might be of value to some of you in your every day practice. The worst of the conditions involved in problem low back cases and those most dangerous in which to attempt any adjustment are Cancer, Tuberculosis, Pagets, Arthritis, and other bone diseases, Fracture, Ankylosed, Deformed and some Disc cases. With the possible exception of the common cold we see more low back cases than any other one type of case, we also lose more low back cases than any other type of case. We should not. We cannot afford to lose a patient to Osteopathy any more than we can lose a friend. Uncertainty is what bothers most patients, but if we explain the condition, tell the patient what to expect and what to do for themselves they will usually return provided that they have not been unduly hurt or frightened by harsh treatment, that they have not been impressed due to incompetent or routine treatment, or that the Doctor is too negative. There is too much of that bad habit of I think, or I guess. It is embarrassing in caring for a low back condition (or any other type of case) to find that we have not been treating the cause or have not made a proper diagnosis, but it is more embarrassing if some one else learns of our mistake. To understand why there is such frequent crippling pain, etc., in the low back, which is the strongest part of the spine, it might be well if we consider the spinal column for a moment. From a purely mechanical standpoint with any change in the alignment of the spinal column with its two anterior and two posterior curves there must be a corresponding change at the tops of the curves. C B D * d , a . b b 15 All Rights Reserved American Academy of Osteopathy® 152 With any spinal lesion at the top of a curve there will be a corresponding lesion at each top of the spinal curves as noted by the corresponding letters. There will also be corresponding rib lesions 1st and 12th, 2nd and llth, etc. Knowing the corresponding tops of the spins.1 curves is of special value when for any reason it is not possible or advisable to manipulate in one arc one can get the same results by manipulation in a corresponding top of another curve. Corresponding spinal lesions can be further divided than those shown in the diagram. For instance adjustment of the second dorsal on the right side will activate liver or gall bladder disfunction and release tension at the seventh Dorsal vertebra. When muscle spasm exists it is caused by one or more rib lesions. With this explanation of the corresponding tops of the spinal curves it should be understood why the low back disturbance is caused by or can be associated with almost any sort of disturbed function, I have not counted the number of causes of low back disturbance, but I recently read an article the writer of which was an Orthopedic Specialist who stated that he knew of fifty-four causes. To name just a few causes of low back disturbances, the nerve center of which is in various spinal areas, Tonsillitis, Sinusitis, Eye Strain, Cardiac Disease, Liver and Gall Bladder Dysfunction, Gastric or Duodenal Ulcer, Kidney Disease, Constipation, Grippe, Weak Arches,Emotions, Fatigue, etc. You all have your own ideas as to where the nerve centers are for the above condition, but in whatever area you find them you still have your corresponding spinal lesions at the tops of the curves. This knowledge is always useful especially when it is not advisable or difficult to treat one area as results can be obtained by treating or adjusting a corresponding area. It is well to remember that to have a disturbed function you must first have irritation in a spinal nerve centre, and also to remember that the spinal cord ends at about the second lumbar vertebra, therefore any low back irritation must first arise in a nerve centre above the second lumbar vertebra. The stopping of an allergy, an occupational or other habit, using a heel lift for a short leg, a directional heel lift for an eversion, or an inversion, or correcting heel balance to relieve lumbosacral strain frequently corrects the existing condition or relieves enough spinaltension so that lesions are easily adjusted. The recurring low back pain recurs only because we have not found or eliminated the cause, that the patient did not have sufficient follow-up Osteopathic care, or he did not follow advice given. The patient should always be advised. There is one type of lesion that acts like a turnbuckle in that it contracts spinal muscles from the occiput to the coccyx and directly or indirectly causes contraction of many other muscles of the body thereby causing various disturbed functions. This lesion is an extension of the fourth dorsal vertebra and must be adjusted in flexion, i.e. by drawing the head forward and if the lesion is an extension side bend the head is also drawn to the lesioned side, your fulcrum being at the point of lesion. At times this lesion adjusts so easily that all you feel is a release of tension, and other times to adjust it will try the patience of a saint. The results obtained In such various conditions is well worth your adjusting it when found. You will not ring the bell every time, but stay with it. The why of how results take place with the unknown nerve conditions is beyond me. I think that Dr. Arthur Hildreth spoke more of a fourth dorsal lesion than any other lesion. To illustrate results of adjusting an extension lesion of the 4th dorsal.. One of the Clinicians of the Out-PatientDepartment of the Massachusetts Osteopathic Hospital asked me to see a patient, stating that the spine was so rigid he did not know where to commence treatment. The patient was a six year old pasty-face boy whose speech was not understandable, the father stating that all. he wanted to do was to sit in the kitchen and play with dolls. He had had him to three mental clinics who said there was nothing they could do for him. In making the spinal examination and evaluating the spinal tissue changes, All Rights Reserved American Academy of Osteopathy® 153 there should be an answer, I think that I stated that the 4th dorsal was the outstanding lesion and demonstrated the adthe answer to the low back problem in diagnosis, while we should use every available justment of same.

Arey, in his Developmental Anatomy, 154 All Rights Reserved American Academy of Osteopathy® fibrocartilage, whose heavy white fibers run from one vertebral body to the other in wide curves, fusing front and back with the anterior and posterior spinal ligament: and dividing into finer fibers above and below to penetrate the plates of hyaline cartilage enclosing the disc. Also some fibers of the annulus lamellosus extend further to become firmly attached to the epiphyseal ring of the vertebral body. Schmorl finds that the vertebral epiphyseal ring, contrary to its name, does not function as a growth zone, but as a fixation organ important in spinal architecture rather than development. The actual growth zone is the surface of the cartilage plate of the disc facing the vertebral body. Fibers from the interior of the disc penetrating the cartilage plates, therefore, exert an important influence on the events of growth. If for any reason they become ineffective, developmental anomalies occur. Beadle's description presents the normal intervertebral disc as a highly complicated organ consisting of (1) the nucleus pulposus, fluid in consistency, elastic, composed of cells able to respond effectively to changing physical demands; (2) the annulus lamellosus, fibrous, strong serving as a capsule to the nucleus pulposua and anchoring it firmly to adjacent ligmentous and bony structures, differentiated fibers at the same time functioning in growth and repair; and (3) the cartilage plates, most resistant parts of the disc, fitting over its ends like drumheads, holding the highly expansible nucleus within bounds, protecting the spongiosa of the vertebral bodies and providing the bodies with their zone of growth. Pathological conditions in the discs are considered in three age periods: adolescence, maturity and old age. In the adolescent spine, one of the commonest pathological findings is nuclear expansion of the discs, seen usually in the lower. dorsal and lumbar areas, apparently never 155 in cervical area.. Where such expansion occurs, the cartilage plates are found to be difinitely thinned and it is here that even the slight trauma of functional activity may cause small breaks, gradually widening into fissures through which the turgid tissue of the nucleus pulposus escapes into the spongy interior of the vertebral bodies. The youthful kyphotic spine characteristically shows a. row of disc prolapses of various sizes and shapes in the lower dorsal and lumbar areas. In youth the discs themselves are ordinarily not much altered, remaining rather well preserved though narrowed due to a part of their substance having escaped. Usually, the prolapsed tissue in young spines does not undergo degeneration. Caution is observed by Beadle in ascribing reasons for the frequency of occurrence of cartilage weakness with subsequent nuc1ear prolapse in adolescent spines; yet in an extended discussion he repeatedly returns to the conviction that developmental weakness must be the basic cause. "It should be reflected," he states, "what a far-reaching change of function the spine has undergone in the assumption by man of an upright habit." In the four-footed animals, this organ, exercising a simple supportive function is not subject to undue strain and stress. The human spine, however, due to tensions and shocks in a. vertical direction, is confronted with conditions that from the standpoint of the horizontal habit are no longer physiological. Also in the human manner of life and occupation these tensions and shocks recur intermittently, so that the adaptive forces suffer from confusion and, so to speak, lack of decision, which can but manifest itself in developmental weakness. Undue strains, as when adolescents become suddenly employed in strenuous occupations or severe athletic activities may contribute to the tearing and fissuring of thinned cartilage plates, but the thinning itself 1946 edition, describes, at about the nineteenth day, in the embryonic disc, between the neural tube and the primitive gut, the formation of the primitive axis of the body. This structure, called the notochord, or chorda dorsalis, is composed of original mesodermal cells of even earlier origin than those of the mesenchyme and around it later the spine develops. As the vertebral bodies form, the notochordal cells in their centers become surrounded by bone cells which crowd upon them and cause them gradually to disappear. In the intervertebral discs, however, the notochordal cells persist as the nucleus pulposus. Undoubtedly, like primitive connective tissue cells in other parts of the body 'these cells exercise an adaptive function, being capable of what some one has described as "an infinite self-adjustment" to body needs. All Rights Reserved American Academy of Osteopathy® 156 cannot be proven to be anything else than A strong resistance of the developmental. cartilage plates to trauma from outside has been observed, as has also resistance to destructive diseases attacking the vertebral spongiosa. The conclusion is that the more usual and most important cause of injury to the cartilage plates is not coarse violent trauma but the imperceptible influence of functional life working upon cartilages which are in some way inferior in resistive power. In middle life, prolapses of the discs often show extensive cartilage injuries with more or less damage to the entire disc:. Often it is observed that large parts of the cartilage plate on one or, both sides of the disc have disappeared or that the disc has pushed through at various Points in the cartilage, like dough passing through a sieve. Fragments of cartilage may be carried into the spongiosa leaving an irregular border between disc and vertebra.1 body. The general degeneration usually involves also the disc which has largely lost its turgor. It is not considered that these middle-age conditions are due to pure trauma. Cartilage plates do not easily give way to physical violence. The explanation is sought, as with the youthful spine, in some primary degenerative change in the cartilage itself. As time passes the cartilage plate becomes progressively brittle and dry, finally showing fissures in its matrix. In aged spines, prolapse of the discs often accompanies osteoporosis of the spongiosa, due to senile changes. The cartilage plates in many of these cases remain intact, though in others there may be breaks, and fissures. The gradual softening of the spongiosa in osteoporosis removes the firm background against which the cartilages rest, allowing the discs to bulge on either side in a wide, smooth curve. In extreme cases the discs are so widened that they seem to occupy a larger area than do the vertebral bodies. In either middle life or old age, if prolapses of the youthful type are encountered, they may be considered as left over from the early growth periods. With regard to age and sexincidence, the examination of 3,000 spines of persons of all ages dying of all causes showed 38% having disc prolapse of various kinds, 39% of all males and 34% of all females. Of the ages from 18-59, 40% of the males had prolapses and 20% of the females. After the age of 60, the males with prolapses numbered only 23% while the percentage of females advanced to 44%. The excess of males during the early and middle periods of life is probably connected with the harder work performed. After the retiring age, women are more active than men as they continue to carry on their housekeeping duties. These findings are considered to indicate that the slight physiological trauma of accustomed activities may be the deciding factor in the eventual fracture of weakened cartilage plates. Having proceeded thus far in his treatise on the discs, Beadle now states that the prolapse he has described is an ideal one only and that actual examples with such a simple structure are very few, for the reason that immediately the prolapse occurs, reactive changes begin and are almost invaribly in evidence in examined specimens. Any given disc prolapse in its early stages shows a whitish, hard consistency due to the formation of cartilage, beginning at the edge of the prolapse and extending inward to completely enclose it. Prolapses of longer standing display a layer of compact bone lying between the cartilage and the spongiosa. These cartilaginous and bony changes are most typically seen in the youthful spine but are also found, more irregularly arranged, in the more destructive prolapses of the mature spine Even in the aged spine, where the cartilages have not been fractured but where osteoporosis of the spongiosa has allowed the disc to bulge into It, a protecting layer of compact bone may be found. The origin of the protective cartilage is traced to cells from the disc itself. The new bony layer has origin from the spongiosa. Newly-formed cartilage may be found inside the disc tissue as well as in the prolapsed part. Also, the torn edges of the cartilage plate are likely to proliferate in the body's attempt at repair. "It must be understood", says Beadle that the tear in the cartilage plate that gives rise to the prolapse of the nucleus is nothing less than a wound, a physical injury . . . Therefore it is to be expected that these wounds will undergo the same healing processes as any others." There is All Rights Reserved American Academy of Osteopathy® a certain difference between the healing processes in youthful discs and those seen in middle and later life. In youthful prolapses the discs retain elasticity enough to enable them to function so that there is no strong stimulus to start the healing pro cess. The tissues protect themselves from further damage by a slowly progressing process that makes an attempt usually unsuccessful to fill the gap in the cartilage and a more successful one whereby a complete capsule of new bone is formed around the prolapse. The youthful prolapse does not degenerate but persists in a chronic state. In later years the more complicated and destructive type of prolapse stimulates to more immediate and extensive healing activities. Blood vessels from the spongiosa enter the prolapse, and often the disc itself, to destroy the disc substance and convert its degenerated parts into, first, granulation tissue, then scar tissue and sometimes even bone. In senile osteoporosis, the healing processes are rarely seen because the spongiosa has little power or proliferation left. So far, the studies of prolapsed discs have been of those prolapsed into the spongiosa. Schmorl, in 1929, made a study of the posterior surfaces of a series of some 2000 vertebral bodies discovering in about 50% of them extrusions of nuclear substance, from the size of a hemp seed to the size of a bean, through fissures in the annulus lamelloseos into the spinal canal, usually in the region of the posterior longitudinal ligament. The causes of these posterior prolapses he assumed to be the same as those of the central ones; namely degeneration and slight trauma. They were found to be subject to the same degenerative changes as the central type. It is noted that purely traumatic posterior protrusions of the disc were also found to occur, not to be confused with posterior nuclear expansion. The traumatic type are usually protrusions of the entire disc and may heal with proliferation of fibrous tissue. In the lordosis of the aged, degenerated discs may soften and swell out into the spinal canal. A section of the book now takes up disc lesions of external origin. Mentioned again, to make the record complete, are the slight shocks of normal life that work on the spine in its daily functional activity, 157 causing fine tears gradually widening into fissures in cartilage plates having developmental weaknesses. Fracture of one or more vertebral bodies was found, as a rule, not to affect the discs. It is striking to note, says Beadle how much of injury of a violent nature can be sustained by the spongiosa with little or none to the cartilage plates. A few disc injuries are recorded, however, and in an occasional case the disc was found to be crushed without injury to the, bone. In a study of disc injuries due to disease, severe destruction of vertebrae by spondylitis in connection with typhoid, influenza, glanders and various other infections was found commonly to occur without injury to adjacent intervertebral discs. The only condition in which extension of infectious spondylitis into the disc occurred was when the cartilage plate had been previously broken and there was free communication between spongiosa and disc tissue. In purulent osteomyelitis, however, vertebrae, cartilage plates and discs alike were found to undergo dissolution and the whole spine to swim in a bath of pus and necrotic tissue. The same was true of the extensive destruction occurring in caseating tuberculous spondylitis. Benign tumors, common in the vertebral bodies were found seldom to invade the discs. Myeloma left the cartilage plates and discs intact. Hodgkins disease of the vertebral bodies did not touch the discs. All kinds of malignant metastases were found to attack the vertebrae, but of 26 spines showing advanced metastatic new growths only two were found with invasion and destruction of the discs. Where prolapses had already occurred, the metastatic tissue had usually grown around them leaving a clear sharply defined margin. The final section of the book discusses the effects of disc lesions on the condition of the spine as a whole. It is stated that the various degenerations and injuries to the discs described in the preceding chapters were nearly always found in association with varied degrees of spinal curvature, including the kyphoses, spondylosis deformans and many transitional and unclassifiable conditions. Excluded is the large and important group of the scolioses. In the scolioses disc pathology All Rights Reserved American Academy of Osteopathy® 158 is not commonly found. The last paragraph of this section and of the book itself summarizes: "This short survey of several welldefined forms of spinal deformity should make it possible to reach a somewhat greater degree of clarity about the part played by the intervertebral discs in health and disease. In the section on juvenile kyphos is an attempt has been made to trace the disease back to a disposition rooted in the constitution of the child, and to suggest a concrete theory of how this may act by examining closely certain gross alterations in the intervertebral discs found in youth. It was then found that an element of trauma, or over-burdening must also come into play, and Schmorl suggests that this is an important indication for disallowing sports or other violent exercise in children at the susceptible ages. In later life the natural changes in the discs have been studied and the gradual loss of their functional adaptability established. Place is also allowed here for an inborn disposition which inclines the tissues to fall a prey to degenerative changes with great readiness in some individuals. But a traumatic element also plays an important part. Tissues which are overtaxed in relation to theirinnate strength undergo the severest changes, and it has been seen how males during the active working years are more seriously affected than females, whereas in old age, when the men have laid down their tools, the figures for the women are the highest. "The great lesson from all these observations is the all-importance of the intervertebral discs in the preservation of the normal form of the spine during the infinite changes of shape, the compressions, extensions and torsions, it undergoes in functional life. How severe this task is, is proved by the exceeding readiness with which the discs yield to senile changes, long before these appear in other tissues; and when this has happened the whole spine shows itself as functionally exhausted, and rapidly gives under the strain, becoming stiff and permanently deformed." All Rights Reserved American Academy of Osteopathy® BURNS' STUDIES OF THE DISK Mary Alice Hoover, D.O. Osteopathic research as to the intervertebral disk antedates by some years the work of Schmorl and Beadle as reviewed in the preceding article. Early in her experimental work Louisa Burns began studies of the spinal articulations and of the disk. "NO satisfactory description of normal or abnormal joint tissues was available when our experiments were begun," she writes. "Part of our earlier work consisted of studies of normal articular tissues using different families of laboratory animals of different ages and embryos of different stages of development . . . Since that time many reports of normal and abnormal structure have been published, verifying several but not all of our findings . . "A study of the intervertebral disk" Burns states, "is a necessary part of the study of the lesion and its effects. We first studied the normal disks of laboratory animals and of a few persons. Since these original studies were made, several other descriptions of the disk and its development have been published. Of these publications one of the most exhaustive is that of Beadle." In Bulletin IV of the A.. T. Still Research Institute, published in 1917, Burns gives a detailed account of her findings regarding the development of the disk. Quoting: "Very early in embryonic life the notochord is formed, following the foundation laid by the primitive streak, itself one of the very first indications of differentiation of structure found in the embryo. The notochord persists as a whole throughout life in only a few of the lowest fishes. It is, in very nearly all vertebrates, superseded by the spinal column. In all mammals, as development goes on, the notochord and its neighboring mesenchyme become segmented. In each of these segments an upper cartilaginous portion becomes the anlage of the body of the vertebra. The lower portion retains in its center the original embryonic notochordal structure throughout life. The mass of cells which ultimately becomes in the adult the nucleus pulposus is surrounded by an area of soft cartilage which retains to a certain extent something of its embryonic qualities throughout life. The nucleus pulposus thus represents what is perhaps the most primitive tissue found within the adult human body." Descriptions follow of adult disk structure, with drawings of cells of the nucleus pulposus and substantia fibrosa. Studies of the disks of the rabbit, the guinea pig, cat, dog, sheep, cow, and human show that variations in the disks when present are due more to differences in size and shape than to essential factors. The nucleus pulposus is found to be without nerve endings or blood vessels and, with the substantia fibrosa, to receive its nutrition from lymph derived from the blood vessels of the adjacent vertebral surfaces. The disk, especially the nucleus, Burns found to be markedly hygroscopic, swelling in all solutions of the ordinary salts, acids, alkalies, tap water and diluted blood, a characteristic important in consideration of its function in giving the spine strength and resiliency. Quoting: "Increased acid content of the blood causes edema of the disks. The fibrous tissue becomes soft and logy, like putty rather than like rubber; like soft lead rather than like steel springs. Such tissues do not return to the normal state after.compression is removed nor do they efficiently resist the influence of abnormal stress." Senile changes are noted, with their effect on normal spinal curves. The effect of preliminary studies as to the effect of vertebral lesions on the disks is given, clinical applications are indicated and treatment for disk conditions outlined. All this some 14 years before the appearance of Beadles' book! Studies of the disks have been continued in the Research Institute from its beginnings to the present time. Examination of the disks adjacent to a lesion is 159 All Rights Reserved American Academy of Osteopathy® ' 160 routine procedure in the experimentation program. In Burns' recently published book, reviewed in another part of this volume, factors concerned in studying the changes due to lesions occupy several pages. Reports are given of experimentally lesioned guinea pigs, rabbits, cats, dogs, of various ages, killed at various times from immediately after the production of the lesion to 5 years later. Some human autopsies were also held. The effect of vertebral lesions on the nucleus pulposus is found to be an increased water content, within 5 to 10 hours, as evidenced by a greater pressure exerted on the peripheral fibers. During successive weeks this edema increases, elasticity diminishes and the fibrous portion of the disk becomes slightly thinner in the area subjected to the greatest pressure by the nucleus. As the lesion becomes chronic, edema diminishes and after a year or a few years nearly all fluid is absorbed from the nucleus pulposus. The typical cells die and become unrecognizable and the intercellular substance diminishes gradually in amount. The entire nucleus becomes whiter and more opaque in appearance, and tougher, harsher and more brittle in palpable quality. Microscopic examination of the nucleus pulposus of rabbits whose lesions have been present for 4 or more years shows abundant granular debris and many fine connective tissue fibrils. A few connective tissue cells are associated with these fibers but there are few or no recognizable cells of the original notochordal type. The granular material is persistently hygroscopic. It has not yet been possible to bring the granular debris in vitro to the condition of normal nucleus pulposus but experiments in vivo indicate that at least a certain degree of recovery is possible if the normal circulation can be established in animals not too old . . . The cells have not been restored in any case and this is not to be expected. The results of osteopathic manipulative treatment on the nucleus pulposus is illustrated as follows: "A litter of 5 young rabbits was selected for experiment. One was kept as a control. A first lumbar lesion was produced in 4, and the lesion was permitted to remain for 3 years. One rabbit was then killed; the nucleus pulposus showed the inspis- sated condition described previously. Two rabbits received 10 osteopathic manipulative treatments which restored normal vertebral relations so far as we could determine by palpation. They were permitted to live for 6 months longer. Lesions did not recur. One of those treated was killed. The nucleus pulposus of the disks adjacent to the lesion showed pulpy material and a few Cells of the notochordal type. The others lived 6 months longer, when the 3 remaining rabbits of the group were killed. The nuclei pulposi of all the intervertebral disks of the control rabbit showed normal structure. The rabbit whose lesion remained present showed normal disks of all spinal segments except those adjacent to the lesion, and these showed the changes. described previously . The rabbit which had received corrective treatments showed normal disks for all segments except those adjacent to the lesion, and these showed almost normal gross structure, though the notochordal cells were less numerous than in a normal disk." The fibrous portions of the disks next to the lesion are found by Burns to be perceptibly diminished in elasticity within 4 days after lesioning in small and young kittens , guinea pigs and rabbits. Elasticity continues to diminish gradually the next few weeks. By the end of a year the fibrocartilaginous portion of the disk has lost much of its matrix. The fine fibers which unite the layers are fragile and easily broken. All the fibers are waterlogged and putty-like in palpable quality and are without recognizable elasticity. During the second year the disk becomes harsh and dry and assumes permanently the form imposed on it by the abnormal position of the lesioned vertebrae. Elasticity is completely absent, flexibility almost gone. After the second year correction of the lesion in laboratory animals is difficult. Many treatments are required and it may be impossible to secure permanent and adequate restoration of normal vertebral relations. However it is possible to increase the mobility of the spine and to relieve the symptoms due to the lesion. Lacking its normal elasticity the disk which has been affected by a lesion for 2 or more years seems unable to readapt itself to its original normal position. Of great interest is Burns' observation on the relation of the hygroscopic All Rights Reserved American Academy of Osteopathy® 161 property of the disks to spinal curvature increased hygroscopic quality of the disks and that many children are found to develop in children.

All Rights Reserved American Academy of Osteopathy® DR. BURNS' NEW BOOK* Mary Alice Hoover, D.O. Many appreciative words have been said about Dr. Louisa Burns' recently published book. Many more should be said. "It establishes experimentally the fact that the osteopathic lesion exerts a disease-producing influence and describes the nature of the disease process by this particular type (traumatic) of osteopathic lesion," writes L. C. Chandler in the book's preface. S. V. Robuck in a foreword says: "Not content to study only the pathology of the spinal joint lesion, Dr. Burns pushed on into the more dramatic and more difficult problem of determining some of its effects upon the nervous system and the organs of the body. The greater lesion complex truly challenges the patience, ingenuity and technical skill of a Pasteur, a Koch, a Metchnikoff or an Ehrlich and requires something of the clinical acumen of an Osler or a Mackenzie . . . This book will undoubtedly become more valued as years pass, for its contents deal with data that are basic." The late, R. E. Duffell, who edited the book for publication, said: "Every osteopathic physician will want to own a copy of this latest book by Dr. Burns." Among significant events at the 1948 Convention of the American Osteopathic Association in Boston, was the initial appearance of this book and of the moving picture** produced by Dr. Burns and the late Ralph W. Rice, complete with sound and color, to illustrate findings as to the effect of certain vertebral lesions on the heart. Graphically described in the book and vividly portrayed in the movie is the heart affected by third or fourth thoracic lesions. Quoting: 'Anesthetized animals show immediate and characteristic pulse changes after an upper thoracic lesion, especially the third or fourth, has been produced. The pulse becomes rapid, weak and slightly irregular. During the next 10 minutes the pulse gradually becomes slower, stronger and more nearly regular, but it never becomes quite normal so long as the lesion persists." "During the several weeks or months after a lesion has become permanent, the heart beat assumes a peculiar, abrupt palpable quality resembling the ticking of a clock and here described as 'staccato'. This quality faintly suggests Corrigan's pulse except that full expansion does not occur. The sudden collapse is easily palpable. It is present even though the pulse shows slightly increased force, for example, during exercise . . . . "If a lesion remains present for several months or years, the pulse, becomes gradually feebler, slightly uneven in force, slightly less regular in rate. After 3 years or more, in certain rabbits, the pulse may become rather rapid as well as more feeble, but in other rabbits the pulse remains slow and weak as long as the lesion persists." "The anesthetized normal animal whose thorax has been opened shows a heart which beats strongly and which continues to belt for a time whose length is determined by the nature of the experiment being performed. After it has been removed from the thorax and placed, emptied of blood, on a flat surface, it stands up in rounded form. If it is beating strongly when it is removed from the thorax, it continues to beat strongly for a. considerable time thereafter.

"Certain cardiac conditions are uniform in the hearts of animals with third or fourth thoracic lesions. During anesthesia and after the thorax is opened, whether or not experiments are performed, the heart beat is visibly less vigorous and less regular than is the normal beat. The contraction becomes weak after relatively short periods of anesthesia, with or without experimentation. After the heart is removed and placed on a table it becomes flattened, obviously because of loss of tone. The heart of such an animal is about two-thirds the height of the control heart so placed. It often ceases to beat after being removed from the thorax even though it had been beating fairly well before it's removal. If the removed heart beats at all, the pulsations are feeble and soon cease. At all times after the thorax is opened the heart Is palpably softer and weaker than the normal heart. Such a heart, confined under a tambour connected with a manometer, rarely moves a column of mercury which is more than 100 mm in height." Histological specimens are obtained from the hearts of animals not used in other tests. The thorax of the anesthetized animal is opened and the heart still beating, is packed in dry ice till frozen. In slides of normal hearts quick frozen while the heart is beating "alternate waves of contracting and relaxing muscle fibers are easily recognizable, but within each wave the striations are uniform. Longitudinal striae are very dim if they are visible at all. Nuclei are distinctly outlined and lie at the periphery about midway between the ends of the muscle cell. "Blood vessels present normal strutture. Arterioles and venules contain a central core of blood cells surrounded by a peripheral plasma layer. In no case does a blood cell touch the intima. Larger blood vessels contain the same peripheral plasma layer, but the central core of blood cells is relatively much larger. The capillaries have a diameter not more than that of an erythrocyte. Many capillaries contain only a thin layer of plasma, with an occasional erythrocyte. "From the histology of the heart of an animal which has had a third or fourth thoracic lesion for a year or more, it might be inferred that this lesion primarily affects the vasomotor control of the heart. Blood vessels are crowded with cells The peripheral plasma layer is nowhere visible. Capillaries contain many blood cells, touching and crowding one another, and distending the capillary to 2 to 5 times its normal lumen. Cells in the act of escaping through the capillary wall by diapedesis are abundant. Erythrocytes crowded against the intima of arterioles and small arteries occasionally are seen penetrating the intima, into the space between this membrane and the subjacent muscular Coat. Minute petechial hemorrhages also are abundant, and these present various stages of coagulation, digestion, and absorption, or of coagulation, organization, and the development of a minute mass of connective tissue. In many cases these small fibrotic areas appear to have diminished the lumen of a vessel; in a few areas a capillary, arteriole or venule appears to have been occluded completely by these masses of scar-like connective tissue. General fibrosis is associated with ischemia of small areas of myocardium. Before fibrosis is marked the heart wall is extremely bloody. It often resembles a sponge which has been soaked in blood. Small coagula are present both in blood drained from the cardiac cavities and in blood which flows from the sectioned or torn myocardium. "Cellular changes found in the hearts of animals with upper thoracic lesions (especially the third and fourth thoracic) appear to be due to changes in nutrition. Living and quickly frozen preparations show constant mild edema. The thin layer of tissue fluid which is present around the cells of the normal heart is greatly increased in the heart of the experimental animal, usually to several times its original thickness. Myocardial cells are swollen, their cross striations are uneven, and the longitudinal striae distinctly visible. Contraction waves found in hearts frozen while still beating are uneven in outline. In each wave small areas appear which seem to be out of place, that is, in a band which seems to be contracting, a small area of relaxing cells may be seen, while in a wave of apparently relaxing cells, there may be small areas of cells which are, apparently, contracting. Nuclei are less distinct than in All Rights Reserved American Academy of Osteopathy® 164 normal hearts. They often lie deeply within the muscle cell and sometimes they lie nearer the ends of the cells than in normal tissue." Atlas lesions or those of the occiput or upper cervical vertebrae, experimentally produced under anesthesia, are found by Dr. Burns to show the following effects: "For a few minutes the pulse becomes stronger, very irregular and usually extremely slow. Within the next 10 or 20 minutes the pulse returns toward normal though it never becomes normal so long as the lesion persists . . . During the next few days or weeks the variation of the pulse waves develop into a fairly rhythmic grouping . . . After six months or so a "missed beat" may be found. Up to the present time no consistent or definite pathology has been found grossly or microscopi- cally in the heart affected by an atlas lesion. It seems probable that upper cervical lesions affect the vagi and their centers and so cause the functional variations." Much more than is quoted here is included in Dr. Burns' chapters on the heart. And the heart is only one of the body structures that she has scientifically explored in relation to vertebral lesions and has reported in this book. On page 39 we note some of her findings as to the intervertebral disk. Equally revealing are studies of the eyes, the nervous system, the tissues of the nose and throat, the lungs, the gastro-intestinal system, and the kidneys. As we close this review we can but echo Dr. Duffell's admonition: "Every osteopathic physician will want to own a copy of this book." All Rights Reserved American Academy of Osteopathy® THE IMPORTANCE OF 'PATHOGENESIS OF VISCERAL DISEASE FOLLOWING VERTEBRAL LESIONS' W. V. Cole D.O. This volume is the compilation of the results of many years of investigation and clinical observation. It is in this publication that Dr. Burns has described the methods of laboratory investigation, the results of experimentation, and the most important of all the practical application of these findings to the practice of osteopathic medicine. Furthermore, throughout this book there is present the underlying concept that the osteopathic physician is primarily interested in the patient with the disease rather than the disease with the patient. The latter is commonly referred to as the symptomatic approach to therapy. This fundamental idea in the treatment of disease has been thoroughly investigated by laboratory methods and these findings are presented in such a manner that they are of use to the clinician. Dr. Burns has spent many years in an accurate evaluation of these factors, and in this book describes why it is as important to remove the mechanisms that permit the invasion of bacterial infections as it is to destroy the invading organism itself. In the present volume Dr. Burns has also described the origin of osteopathic research and its development since the turn of the century. It is true that pure research material is often not immediately useful to the general practitioner, and this book is not to be considered a 'practice book'. The material contained is essential for a complete understanding of osteopathic principles and philosophy both of which are necessary to the general practitioner and specialist in osteopathic medicine. Osteopathic research has long been the step child of the profession and it is only through the efforts of Dr. Burns and more recent investigators that this phase of professional endeavor has reached the importance it deserves. The advance of osteopathy will depend upon both laboratory and clinical investigation. Although much of the reported material in the present book is based on a purely scientific approach Dr. Burns' wide clinical experience has influenced the conclusions. For this reason they are much more valuable to the practising physician than they otherwise would be. The aim has always been to utilize the experimental results in practical clinical osteopathic medicine. This is a book with which every osteopathic student and practitioner should be familiar and will become a valuable source of explanation for phenomena encountered in the practice of osteopathic medicine. DR. LOUISA BURNS AND HER RESEARCH LABORATORY Mary Lewis Heist D.O. If I wanted to do something nice for you, I know what it would be.

All Rights Reserved American Academy of Osteopathy® FINDING THE STILL (OSTEOPATHIC) LESION Perrin T. Wilson D.O. There is ample evidence that the ordinary American M.D. classes Osteopathy in the category of massage and physiotherapy. Within the month previous to my sail. ing for this conference I had two specific illustrations of this understanding of Osteopathy by two prominent Boston M.D's. One was an internist, the other a surgeon. The Internist called me and said that he was attending a former patient of mine who had been stricken with a cerebral hemorrhage. The patient wanted a treat-,, ment. The Internist said, "I don't see __ what good massage will do in such a case,, but it is alright with me for you to go and see him. Maybe the visit will help his morale". The surgeon called and said that he had just done a hysterectomy on a patient of mine and her back was troubling her. He thought physiotherapy would help her and suggested that since the patient wanted me it was agreeable to him to have me see her. Another thing we occasionally hear from those who think they know what Osteopathy is,, concerns a type of treatment used in the Pacific Islands by the natives. I have actually heard it said, "Why Osteopathy was practiced by the Micronesian Islanders before Dr. Still was ever born." There certainly is a type of spinal treatment practiced by the natives, and it is indeed very beneficial. My sister, a missionary to those Islands has had the treatment. Young girls from five to ten years of age are trained as 'treaders". The patient lies on his face and the child works up and down one side of the backbone treading with her toes. Then she crosses over and works up and down the other side of the backbone in the same way. A great deal of treading is done over the muscles of the buttocks. Sister says it is very beneficial but in a recent letter she said, "I hope in a couple of years to get a holiday so that I can go to Hawaii where I can get a good adjustment between my shoulder blades." If the word "adjustment" is kept in the forefront of the physician's mind, he will do things for his patient that no amount of massage, physiotherapy or "treading" can possibly do. Dr. Still adjusted the various structures of the body to fit the pieces together in a way that they were intended to be. The problem we face is to find that structure which needs adjustment; and that is what I want to discuss with you at this time. With the aid of certain members of the Academy of Applied Osteopathy I have worked out a series of tests of motion which I believe quickly demonstrates the presence of a Still Lesion in certain areas of the body, and having then settled upon an area where trouble is, a more careful search of that area is made to determine the specific vertebra or vertebrae involved. I seat the patient on the table and extend the head and neck. The head should follow an arc of approximately ninety degrees. If it stops short of that I 0 register it thus: H-ext 60 . Now I am reasonably sure that there is trouble in the top three cervical vertebrae or, of course, it may extend down to the upper thoracic area. Now flex the head. In flexion the head should describe an arc of 0 approximately 45 . I do not register normals. Having tested for extension and flexion, I proceed to right and left rotation. Normal rotation approximates ninety degrees. Frequently we find rotation restricted, and it may be registered thus: 0, This would indiH.r rt 60 H.r lft 90o. cate that rotation to the left is normal and therefore the restricted rotation to the right is not due to a general stiffening found as we grow old. As a matter of fact we often encounter elderly people in excellent health who do have ninety degree rotation right and left. In this illustrative case we would be reasonably sure of finding one of the bodies of the vertebrae from C.3 to T.2 side slipt to the right. Now to determine the presence of a Still lesion from T.2 to T.8 or 9, I drop 168 All Rights Reserved American Academy of Osteopathy® first one shoulder and then the other.

The Osteopathic treatment of Asthma is divided into two phases. First what the patient does for himself, and second what the Osteopathic Physician does for the patient. Each of the above divisions are subdivided in the following manner: I The patient's responsibility entails a. rest b. upper thoracic friction c. diet d. breathing exercises e. elimination f. avoidance of air laden irritants II The Osteopathic Physician's responsibility entails a. alignment of upper thoracic vertebrae b. freeing of the 4th and 5th ribs both right and left c. ventral technique to free diaphragm d. alignment of the occiput e. cranial flexion f. inhibition between the 4th and 5th thoracic transverse process Under I(a), we must realize that asthmatics are apt to be excitable above the average individuals. The paroxysms of Asthma are very exhausting, and rest is more essential to asthmatics than to the ordinary individual. These people as a rule don't want to rest, especially between attacks, so we must be very definite about this and see to it that he takes adequate rest. The minimum time that should be spent in the horizontal position is nine hours out of each twenty-four. This need not be taken all at 'one time, but should not be, skipped. I would rather an asthmatic take ten hours a day in the horizontal position than eight. Make sure he gets rest enough! I(b), The patient should take a bath towel, or friction brush, and use friction much as he would in drying between the shoulders. The idea was given me by Dr. C. S. Edmiston whom I would like to quote as follows: "In Asthma the conditions are somewhat different. The skin in an asthmatic case may have a normal amplitude of reaction but it is a thin skin, its vessels are rarely ever full, and it possesses an acute degree of sensibility, this special quality makes it susceptible to affection from any wandering stimulus. This whole complex affair is caused by a lazy skin, a thin skin, a poor skin. The treatment is to try and restore a normal skin function which can be done in many ways. Friction alone will do it, loosening up the shoulder 'girdle and stimulating the skin nerves along the spine manually will do it. And any treatment designed to cure the condition must take the condition of the skin into account." I have found this to be helpful. One husband applied the friction so vigorously to his wife that he created a blister as large 'as the palm of the hand. That patient has not had an attack in five years. I(c), It has seemed to me that whether or not the skin allergy test registers negative to wheat, it is a good thing to eliminate this item from the (diet. For many years I have used rye-krisp or hard tack in place of bread for asthmatics, and asked them to eliminate wheat in every form. I am convinced that it has helped to modify the severity of the Asthma. Few patients will completely cooperate in this, and one must be constantly checking to see that the orders are being carried out. An elimination diet consisting of Pluto water and nothing but fruit for three days is sometimes used. Following this add one item at a time until a food causes asthma. This may be more accurate than the usual scratch tests. 170 All Rights Reserved American Academy of Osteopathy® 171 I(d), Some asthmatics use practically no diaphragmatic breathing. These persons should be taught to place the hands akimbo on the lower ribs and move these ribs laterally and medially as far as possible, particularly medially. This should be done as an exercise morning and night and depending upon the reaction can start with six inhalations and six exhalations. Each time, gradually, the number may be increased until each period of exercise consists of twenty five. I(e), Free elimination from the bowels should be encouraged. Not by cathartics but by enemas, either an oil retention enema or plain water. copious water drinking will often help a sluggish bowel. Hot fruit juice drinks is another good way to normalize bowel activity. Cathartics should be avoided, and I am sure there are few people who can not control their bowel elimination by drinking plenty of water. Keep this item in mind when treating asthmatics. I(f), Air laden irritants are certainly factors in certain asthmatics. Horses, cats, dogs and even canary birds have been found to be the specific allergy. that starts an attack. Plant life also comes in for its share as an exciting cause of attacks. House dust, mattress dust and pillow dust should be carefully checked. If we have an air conditioned room available one can readily place the patient where air laden irritants may be eliminated. It has been my experience that with proper Osteopathic and hygienic regime instituted, the air laden irritants become less of a factor. II(a), The alignment of the upper thoracic vertebrae may be done in any one of a number of ways. Nearly all of these cases present a segmental break at the fourth thoracic vertebrae. The upper four vertebrae side bend to the left as a segment with the spine of the fourth rotated towards the right and the body of the fourth side slipt to the right on the fifth The first, second, third and fourth thoracic vertebrae seem to move as a unit as their spinous processes are in alignment while the spinous processes of the fifth, sixth, seventh and eighth are also aligned but at a different angle. It has been my custom to place the patient on the table face down, but up on his elbows and the forearms parallel to the table lying out in front of him. The points of the elbows should be far enough forward so that the upper arms are at a right angle to the table, or slightly front of a right angle. This position suspends the spine in a hammock of muscles, and cannot hurt the breasts or sternum. I stand on the side of the table so that I face his left side. I place my right hand on the spine in such a way that the knuckle of the middle finger is on the right transverse process of the fifth thoracic vertebra and the heel of my thumb on the left transverse process of the fourth thoracic vertebrae. My left hand in on the top of the patient's head, which is in easy flexion. Do not place the left hand in a position near the back or crown of the head because it is not desirable to get forced flexion of the neck My body is equally placed between my two hands and I lean down so as to get my shoulders in a mechanically easy position to approximate my two hands. I turn the patient's face slightly to the right and side bend the neck and upper four thoracic vertebrae slightly to the right. In this position I am ready to use a quick light thrust approximating the two hands. I may at times just use a strong slow effort to approximate the hands. The pressure on the transverse process of the fifth drops it from under the fourth permitting the fourth to side bend to the right. The pressure on the transverse process of the fourth helps to drive it upward and aids in realigning the segment. If I am not adept enough I may adjust this area in the following manner: The patient stays in the same position. I place the pad of my right index finger over the left transverse process of the fifth thoracic vertebra, and the pad of my right middle finger over the left transverse process of the same vertebra. I then place my left forearm (close to the elbow) over these fingers and I use a quick thrust with my left arm in any forty-five degree angle towards the table and towards the head. II(b), With the patient in the same position, I draw the angle of the fourth right rib down and push the angle of the fifth right rib up. I reach around front with my left hand and find the front end of the fourth right rib so that I can raise it as I lower the angle. I reverse this process for the fourth and fifth left All Rights Reserved American Academy of Osteopathy® 172 ribs, separating them at the angles instead of approximating them as shown for the right side. Either in this position or with the patient sitting up, I make sure the front ends of the ribs are perfectly spaced. II(c), Ventral technique in Asthma is designed mostly to increase the flexibility Of the diaphragm and lower ribs. Often these cases may have a big barrel shape chest but the lower ribs are drawn in and there is very little expansible ability. In adjusting that area I have the patient lie on his back and I place my thumbs low on the sides of the ensiform cartilage, with my fingers resting over the lower ribs. On deep expiration I sink my thumbs into the muscles of the abdomen as if I were helping to push the diaphragm cephalward. At the same time my fingers over the lower ribs press medial. On inspiration my hands remain in the same position, but my pressures are transferred to the palms and heel of my hands as I help the ribs flare laterally and raise a bit. Care must be used in these techniques because a slip of the thumbs on expiration, or the hands on inspiration, may cause a skid over the cartilages resulting in a painful bruise or possibly a costo-chondral separation. I have had one or two accidents of this nature, but none where the tenderness lasted over three to four weeks. II(d), You all have your own methods of adjusting the occiput. I have usually found the position of this bone one of extension on the atlas on the right. This is usually spoken of as an anterior occiput (Rt.). I use many different methods to lift the occiput, and draw it back on the right. The movie, "Anterior Occiput", available from the A.O.A. goes into detail on my usual procedure. II(e), Cranial flexion--cranial technique is so difficult and complicated that it is usually wise to take a course specially designed for cranial work, but if you depend upon respiration rather than applied force for the adjustment there is no harm in trying simple flexion of the crani- u m Dr. Sutherland feels that all Asthmatics have the cranium fixed in extension. That is both greater wings of the sphenoid are up and the occiput is up. In thinking of these movements one must of course think in terms of infinitesimal strains. When one gets used to the feel of a craniurn that is locked, and one that is not, it is not too difficult to tell which condition exists. To this day, however, there are many cases that I cannot be positive about. I try to bridge the fronto-parieta1 suture line to have my left thumb on the right greater wing of the sphenoid and my ring finger or middle finger on the left greater wing of the sphenoid. My right hand cradles the occiput from right to left with the occipital protuberance cupped in my palm near the little finger border. I hold the cranium thus in easy flexion using traction downward towards the feet on the occipital protuberance, and holding the greater wings of the sphenoid downward towards the chest, not towards the table. The patient is then asked to breathe (deeply either in sniffs or one continuous breath and to hold as long as he reasonably can. Usually just as he starts to let his 'breath out, one can feel an infinitesimal give. There is, of course, not as much motion as in a sacro-iliac as it lets go, but there is a sense of relaxation and if the suboccipital muscles are palpated before and after, one can tell whether or not the. cranium has unlocked for these muscles will feel more normal in texture. II(f), I like to sit the patient up at the end of the above manipulations and place my fingers over the first ribs and my thumbs between the transverse processes of the fourth and fifth thoracic vertebrae. In this position I use deep pressure on the fingers and thumbs for about two minutes. This pressure alone in an acute attack is often effective. I like to treat asthmatics once a week for one to two years. It may be discouraging but the outcome is usually worth it. All Rights Reserved American Academy of Osteopathy® . OSTEOPATHIC ADJUSTMENT IN PNEUMONIA Perrin T. Wilson D.O. Before the advent of the Sulpha drugs and Penicillin there was very little in the medical field that was of value for the care of pneumonia. Even the use of serums was of questionable value, yet the experience of the Osteopathic physician in caring for pneumonia was exceptionally good. I believe that I am conservative when I say that as a profession our death rate was less than five per hundred cases treated. I personally handled sixty-six cases with but two deaths. Both of the cases that died got out of bed against orders. I think I would have pulled one of these thru if my orders had been followed out. Now, of course, the publicity given modern medical procedures in pneumonia have created such a pressure of public opinion that the Osteopathic physician is practically forced to employ some medication. Having had some experience with post pneumonia patients treated with the above mentioned drugs who have not had the benefit of Osteopathic supervision, I can say unequivocally that certain patients have poor reaction to said drugs. I am of the opinion that Osteopathic care alone would still give a lower death rate than can be duplicated by any medical procedure, but since we must use penicillin in these cases, I am convinced that a delay of twenty-four to forty-eight hours in the administration of the drug is beneficial, thus allowing the body's own defense mechanism to function. I am convinced that the amount of drug necessary is less and the recovery faster if this delay is employed. One of the interesting things about reviewing the Osteopathic treatment of the different doctors who have been successful in handling these cases is the variety of technique employed, all of which, with the exception of one, has one thing in common viz : lymphatic drainage. Dr. Medaris abducts the arm to a right angle and with one hand on the heads of the ribs uses the other to pump the arm in and out getting drainage in the axillary lymphatics, and through the intercostals. (demonstrate) Dr. Geo. Riley says, "I sat down beside the bed and placed my eight fingers under her body on the left side of her spine, the side next to me, and from the seventh cervical down, began the long siege of relaxing those tense, contracted and excruciatingly tender muscles. Patiently, persistently, I gave all I had to the relaxing of those spinal tissues on both sides. I kept up my determined effort until I secured that reaction, that feel that I was so intent upon obtaining." (demonstrated) Dr. Still wrote, "I have successfully treated many cases of pneumonia, both lobar and pleuritic, by correcting the ribs at their spinal articulations". Dr. Harry Gamble says, "I feel my best weapon is elevation and separation of the ribs, springing the spine gently but firmly as much as prudence permits." Dr. Gamble always manipulates the legs because, "We must remember that the patient has but so much blood and that when blood mass is congested and stagnated within the chest or lungs, there must essentially result a corresponding lack of blood or anemia in the extremities." (demonstrate) Dr. 0. M. Walker said, "I thoroughly relax all of the deep muscles up and down the spine, with the patient on his face, going in deeply pushing or drawing the muscles away from the spine, relaxing all of the deep muscles and getting as much motion in each vertebral joint as possible." (demonstrate) Dr. Ralph M. Crane, who had probably treated more cases of pneumonia than any of the rest of us had this to say of treatment. "The lesions most involved in pneumonia are those of the third and fourth dorsal. I believe this has been generally recognized. To most effectually treat them, it is best to have the patient lie in the dorsal position, the operator carefully slides both hands, palm surface up, under the covers until the fingers rest on the spine at the level of the third and fourth dorsal, being extremely careful not to allow 173 All Rights Reserved American Academy of Osteopathy® 174 the air to rush under the covers. Lift the spine somewhat. After a few minutes, if the proper pressure is applied, the operator senses a relaxation of the spine. The sensation is as though the patient is letting go of a tension, and is comfortably relaxing and allowing the operator to lift that section of the spine from the bed without resistance. If the operator is in too much of a hurry or uses too much force, the patient invariably resists." (demonstrate) Dr. John A. MacDonald, with whom I had worked on pneumonia cases, had the objective of maintaining maximum diaphragmatic excursion. He did this by grasping the lower ribs and in rhythm with respiration, increase the excursion. (demonstrate) I have given you this cross section of opinion so that you will see that there is no standardized treatment of pneumonia by Osteopathic physicians. I am strongly of the opinion that there is an optimum Osteopathic procedure in this disease. It has not yet been worked out because no one physician has taken the trouble to see and record the reaction to different procedures; no one physician sees a sufficient number of cases to draw conclusions, and Osteopathic technique has been such an individualistic art that we have not cooperated to develop a prescription for Osteopathic procedure. It has seemed to me that much of the Osteopathic procedure mentioned above while possibly beneficial is arduous and unnecessary. I give you my conclusions for what they are worth. I know these procedures work for me and I wish they might be tried on a sufficient number of cases to see how well they work in other hands. 1. Keep the twist out of the spine. If we have a right lower lobe involved you will find a segmental break in the spine whereby the transverse processes 'and angles of the ribs from the sixth down are posterior to those above. Rotate these forward until you feel the release as they move. This may be done right through the bed clothes with the patient lying on the left side and a broad contact with the hand directly over the transverse processes. 2. Traction on the occiput. With the patient on the back cup the occiput in one hand, and the forehead with the other.. Use slow rhythmic traction until the' occiput is felt to lift from the atlas. 3. Raise the diaphragm. The abdominal contents may be lifted and forced against the diaphragm with benefit. Also reach in below the covers and grasp the lower edge of the chest, cage on each side and draw towards the head on each of three inspirations. 4. Extend the third and fourth thoracic vertebrae. This may be done as outlined by Dr. Crane above. It should be done carefully and until the patient lets go. This procedure might take as much as thirty minutes at the first visit, but should not take more than ten minutes at any subsequent visit. Usually two visits a day are sufficient. In our hospital where interne service is available three adjustments a day are given, and in severe cases we advocate a five minute treatment each hour. Now it may be that the unorthodox orders for nursing care which the successful Osteopath employs may contribute a good deal to the low death rate in pneumonia at Osteopathic hands. 1. Bathing the patient is not permitted and an alcohol rub is anathema to a good Osteopath. There is no doubt but that vaso motor shock is an item in the causation of pneumonia and cooling to the surface of the skin should be avoided at all hazzards. The patient may smell bad. it doesn't bother the patient and the nurse can stand it for the few days of the disease. A hot towel rub may be employed if used under the bed clothes. 2. Two or three acid enemas should be given at once and then it may be well to avoid future interference with the bowels until the temperature is down. Irrigation with a low tube and a two way valve may be used if desired. Dr. Crane did not use any enema nor did he use cathartics. 3. Wear a sweater or jacket. This must include sleeves. We would like no air to reach the skin at any time. 4. Hot water bottles. One at the feet if a child with a bad cough, this one can be at the buttocks. One on each side of the patient. Hot drinks every hour 5. No food. if the patient will take them. Hot water-lemon--orange--prune--tea--gingerale--tomato or pineapple juice may be employed. All Rights Reserved American Academy of Osteopathy® 175 Some patients are so annoyed by hot drinks that we have to substitute cold, but a short explanation to the patient of the advantage to them of the hot drink usually brings ready cooperation. 6. Do not have the bed clothing too heavy. It is best to have the patient between blankets instead of sheets, and a puff is better than a series of heavy blankets. 7. Air should be circulating and warm, also humified. In the home an electric plate and a tea kettle with the snout pointing towards the patient's face is of distinct advantage. 8. Visitors should be excluded and the doctor should not whisper in the hall to the nurse nor to members of the family. Talk loud or not at all until well out of ear shot. 9. Turning the patient is not essential when it is getting Osteopathic therapy, but it is well to shift the patient's position every few hours if it makes them more comfortable. 10. Do not move from the bed in which he is taken sick. Raising the legs of the head of the bed about six inches is helpful, and use a very low pillow. At least one as low as the patient will permit . All Rights Reserved American Academy of Osteopathy® ANGINA PECTORIS Perrin T. Wilson D.O. I have read carefully Dr. Still's Research and Practice to get his idea on Osteopathic Therapy for the condition known as Angina Pectoris. Possibly in the pioneer days when he practiced, heart disease was hot as prevalent as today, or at least it was not recognized for he gives little on the treatment of the heart. He seems to blame the failing function of the lungs for creating back pressure and hence heart disease. Fortunately or maybe I should say unfortunately I have seen many cases of Angina Pectoris and Coronary Disease in my thirty years of practice. I feel confident that Osteopathic Therapy has much to offer these cases. Let me list the Osteopathic Objectives which I believe to be beneficial. 1. Extend T 1,2, and 3. 2. Adjust T. 3 and rib (left) 3. Raise the sternum 4. Raise the diaphragm Here too the patient has certain responsibilities which I list. 1. Rest 2. Mental poise 3. Correct the hunch of the shoulders-- set back from table 4. Wear an abdominal belt 5. Diet 6. Fomentations to the T - L area 7. Exercise Now I am a family physician and not a heart specialist, and on most of these cases of Angina Pectoris I have the help of a cardiologist. However, I do not relinquish the patient for I am convinced that much can be done Osteopathically. There are of course fat men and thin men, and tall men and short men who have Angina Pectoris, but my observation has been that there is a certain spinal type and chest type. The anterior curve of the neck is exaggerated, and T 1,2,3, and often c 6 are in flexion. This raises the posterior end of the ribs. The whole sternum slips downward, the first section not as much as the second section, carrying with it the front end of the ribs and the top of the sternum drops backward narrowing the thoracic inlet. The lower-end of the sterium pushes forward. Let me sketch it if I can. Note the normal doming of the diaphragm in the normal chest, and the flat diaphragm in the angina pectoris and coronary disease chest. I am ready and willing to have this posture type refuted by any heart specialist for I do not see these cases by the But I am willing to predict that hundreds. you will be much pleased with results in. the treatment of these cases if you will attempt to correct the structure along the lines I will show you. Item 1. Adjustment of the upper thoracic vertebrae requires much traction. The head may be pulled off the table as the, patient lies on his back. The edge of the table being at T 3. Traction and gentle extension will gradually straighten the cervico-thoracic area. Under exercise I have the patient assume this position across the edge of a hard bed or while lying on a book. I have him place his hands under his head to support the neck and spring the upper thoracic vertebrae backward. Item 2. There appears to be a segmental break between T 3 and T 4 and an especial effort should be made to bring T 3 back to its correct position on T 4. Sometimes I have the patient assume the exercise position I have mentioned while I put my thumb and forefinger under the patient to grasp the spine of T 3. With my left hand on the patient's forehead I extend and swing right and left till I feel T3 176 All Rights Reserved American Academy of Osteopathy® 177 give. Examine carefully the front end of the third ribs. It has been my experience that the left rib is depressed at its front end. By standing in back of a patient sitting on a stool it is easy to reach the rib with the right hand while the left hand raises the left arm of the patient to get the help of the pectoralis minor muscle. When all tissues are tense have the patient inhale deeply as you tease the front end of that rib up and anteriorly. Item 3. The whole chest cage should be raised by grasping the ribs and pulling up on them. Possibly the patient can reach around your body as he lies on the table and you stand at his head. Thus as you lean back hi's muscles raise the ribs. At the same time your hands guide the ribs and sternum. Item 4. It is of course difficult to reach the diaphragm but Dr. Carl McConnell used to employ a technique which I use. The thumbs are placed one on each side of the ensiform cartilage as the fingers are spread out over the lower ribs. The patient now takes a deep breath while the physician maintains contact with his hands. The patient then exhales as far as possible and the operator sinks the thumbs deep into the tissues pressing cephalward as the fingers press medtalward on the lower ribs. I repeat once or twice. Patient's Responsibilities Item 1. Rest should be taken in the middle of the day and not less than nine hours at night. Item 2. It would seem to me that as in ulcers of the duodenum the mental habits of the patient have much to do with Angina Pectoris. Certainly fear of death is a usual phenomenon while the pain is on. In three cases of Angina Pectoris, who later developed a senile dementia, all pain disappeared and one case in particular could walk up stairs freely whereas before she lost her mental alertness, she was unable to walk on the level to say nothing of the stairs. Item 3. Most of these cases are what I call shoulder hunchers. Instead of allowing the shoulder girdle to relax and rest comfortably on the thorax, the muscles are tensed and the shoulders held up tense. I believe this to be an Important item in the relief of Angina Pectoris and I go over this with my patient at each visit. Item 4. An abdominal belt which holds the belly wall in and holds the diaphragm up by pressure on the abdominal contents is very useful. It helps to take the weight of the heart off of the large blood vessels and tissues from which it is supported. Item 5. These patients should of course avoid eating large meals. If hungry eat more often. Coffee is undoubtedly a sympathetic system stimulator and should be eliminated. Since smoking is certainly one of the main causes of Berger's Disease, I see no reason why it would not effect unfavorably the arterioles of the heart and I attempt to stop that habit. Item 6. If there is a general cardiorenal syndrome with hypertension, I try to have the patient take hot fomentations to the thoraco-lumbar area twice a week. This may be done easily by protecting the bed with oilcloth or rubber sheet, wringing out a towel with hot water, lying on the side apply the wet towel, place a hot water bottle against it and cover with a big bath towel and rest there for an hour. Several of my patients do this for themselves without bothering other members of the family. Item 7. Exercise to strengthen the abdominal muscles and to extend T 1,2, and 3 should be instituted. Just lying with a book under the shoulders for fifteen minutes twice a day will help correct the flexion of the upper thoracic. Pathology may of course have progressed to such a state when the patient is first seen that one cannot do much in the way of a cure but even in extreme bed-ridden cases the relief a good Osteopathic treatment produces is well worth the effort. All Rights Reserved American Academy of Osteopathy® SCIATICA Perrin T. Wilson, D.O. Oftentimes a brilliant cure of a case conditions the mental attitude of a physician so that it handicaps him in the treatment'of similar conditions in the future. This occurred with me in Sciatica. On my summer vacation after one term at the Osteopathic College, I was called to see a neighbor who was suffering terrifically with Sciatica, and low back pain of a month's duration. It appears that he had had consultation with Dr. Goldthwaite's Assistant who told him it was "Goldthwaites Disease". He might be laid up for months and could never go back to his job as carpenter. I was able to get a very good case history. This man was stirring cement in a bin. There cement was thick and hard to work so that he placed the handle of his shovel against the right hip to reinforce the push . On one of the thrusts the shovel hit the head of a nail that had worked, up through the floor of the bin. The shock to his innominate was severe but he continued with his job. At noon he lay on the ground for a rest and when he went to get up it was difficult to move because of a backache. The next day he worked with difficulty and quit early. The following day he didn't work. A few days later the pain extended down the right leg. At the end of a month he was more or less bed-ridden and used crutches when he moved about the house. As I had not had training in Osteopathic adjustment I made no attempt to treat the man, but told him to call an Osteopathic Physician. The next morning the wife came to my house and said, "Fred was very much impressed with the way you traced the cause of his condition and he wants you to try what you can do". Not knowing any particular type of adjustme.nt I figured that if a blow by a shovel had hit the right innominate backward, I would grasp the innominate and pull it forward. I therefore knelt upon the bed flexed his thigh so that I held his knee in my axilla. The heel of my right hand was o.n the tuberos ity of the ilium pushing towards the bed and my left hand circled the crest pulling up on the posterior superior spine. My axilla pushed down on the acetabulum. This reversed the process that occurred with the shovel. I was inexperienced, nervous, and not sure of just what I was doing. After about five minutes of this I had to rest. On the second try between the nervousness and the strain I began to shake Suddenly there was a very perceptibly. loud pop which scared me to death, and I jumped off the bed. The patient said, "Oh! what a relief." I cautioned him to stay abed and that I would be over the next day. The following day he was up shaving when I arrived. He waited two days more and went back to his old job and never had any more trouble. It took me several years to get over the idea that I ought to cure every case of sciatica in one treatment by correcting an innominate that was posterior or as is now spoken of as a flexion lesion of the sacrum. In the presence of sciatic pain it is well of course to rule out cancer of the lumbar vertebrae or sacrum, tumors of the prostate or uterus. These are rare but do occur as does diabetes. Osteopathic Therapy for Sciatica entails the following: 1. Adjust the Lumbar Vertebra if offending 2. Adjust or remove a ruptured disk 3. Adjust the Sacro-iliac if offending 4. Adjust the head of the femur in the acetabulum if offending 5. Adjust the foot if offending 6. Relax the sacro-sciatic (sacrotuberus) ligament The patient should: 1. Be abed on a hard mattress 2. Never sit in a semi-reclined condition 3. Lift with the knees not the back 4. Wear a lift in the heel if indicated (rare) 5. Detoxicate himself 178 All Rights Reserved American Academy of Osteopathy® 6. Exercise In my previous lectures I have outlined how to find the offending lesion so that I will not take up all of the six items listed under Osteopathic Therapy. The Osteopathic Therapy for 1 and 2 is the same and since they are the most common causes of sciatic neuritis I will discuss them. 179 posus which will be squeezed not only to the right but backward. This force tends to rupture at the edge of the posterior spinal ligament. But it is my opinion that in most instances it does not rupture but decenters in the cartilage, preventing straightening up and causing a list to the right.

At reflexes. Let me quote from "The Neural least since I have been adjusting on this Basis of the Osteopathic Lesion" by Irvin basis my results have been faster. M. Korr, Phd. Journal of A.O.A. Dec. 1947. The nucleus pulposus as you know is "It is concluded that osteopathic the universal joint around which the verte- lesion represents a facilitated segment of bra can flex, extend, or side bend.

In preparation for this adjustment I have found it advantageous to get general traction for a few minutes. This may be done by having the patient suspended from the roof with a sling under the arms as Dr. Still used to do. Or the patient on face may grasp the head of the table or bed while the physician steps between the feet and holding one to each side leans backward getting good traction. Now let's put a pillow under the thighs to get lumbar extension. Stand at the left side of the table, put the heel of the right hand on the left transverse process of L 4 and think derotation of the body and squeeze of the nucleus pulposus. The direction of force then will be towards the table-- towards the transverse process of L 5 and towards the right. Spring till you feel it roll. Ask the patient to breathe deeply. It aids correction. While L 4 is in my experience the most common offender, it is by no means universally so. In fact I have found L 3, L 5, and L 2 involved in cases of sciatica neuritis. One case in particular was one of my own profession, a Dr. C. from Maine, who had a left sciatica of long standing. He had had his sacro-iliacs popped; his lum bar popped; a lift put in his shoe, diather my, and a brace used. Careful diagnosis showed the condition to be L 2 in just the position explained above. The technique I used was exactly as outlined. Let me quote from his letter to me received one month after adjustment applied once. "Since I saw you I have been really normal for the first time in seven years." Item 3. There are many ways of adjusting the sacro-iliacs and I will not go over them here. Item 4. Is rarely involved but should be checked by standing at the foot of the table and grasping the heels in such a way as to rotate the femur in the acetabu lum. If there is a drag or restrictton in motion, I place the patient on the right side, slip my left arm between the thighs right up to the buttocks and place my right hand on the lower end of his left femur. Thus I can use my left arm as a fulcrum to pry the head out of the acetabulum and loosen all the muscles. I then turn the patient on the back and use Dr. Still's technique--Research and Practice P. 53: "Bend the knee very slightly, place one hand under the foot and the other hand under the trochanter Major; with the hand at the foot while the leg is bent, push knee up towards patient's face; put your chest or chin against the knees and with chin or chest push knee from you, --- -- so, bring the lame leg over and across the knee of the well leg, pull down slightly on the foot and as you take the lame leg off the sound knee straighten the leg out." Item 5. The sacro-sciatic (sacrotuberus) ligaments may be relaxed by deep pressure at its attachment along the posterior border of the ischium. This ligament is usually not tense if the sacroiliac joint is not involved. Now we turn to what the patient should do. Item 1. Unless the pain is severe it is hard to keep the patient abed, but bed rest on a hard mattress certainly aids recovery. Most of our patients try to keep going. A former Governor of Massachusetts had sciatic pain for two years before he came for Osteopathic care. I said, "Governor, will you give us twice a week for three months to see what we can do?" He said that that was better than an operation which had been decided upon by his other physicians. At the end of two months just as the pain was beginning to subside some he walked in a parade for four miles. We were four months working on him, but a check five years later showed there had been no return of the sciatica. Item 2. So many times we get these patients quite a bit better and we suddenly find them go bad. Frequently we learn that they were sitting up in bed reading or to eat a meal; or were sitting on a chaise lounge, or in over-stuffed furniture with their feet on a foot stool. A semi-reclined position will surely decenter the nucleus that has once been misplaced as you can see if you followed my reasoning on the original cause of the pain. Item 3. Requires a retraining in methods of stooping to pick up objects. The use of the leg muscles must be encouraged and the knees should always be bent. In making a bed--touch the knees to the edge of the mattress. In stooping to the floor have one foot ahead of the other and bend the knees well down. All Rights Reserved American Academy of Osteopathy® 181 Item 4. Rarely is it necessary to wear a lift in the heel of the shoe in sciatica. If Osteopathic Therapy has been well applied the sacrum will level fairly well, but occasionally where a definite short leg exists, it is advantageous to use a lift. Item 5. A number of cases of sciati ca seem to be complicated by a full bowel or at least a toxic bowel. It is usually good practice to empty the bowel with enema or irrigations and to place the patient on a fruit juice or raw vegetable diet for a few days. Item 6. In cases of sciatica from an unstable low back, I use exercises to strengthen the back. (a) with patient on the face lift thorax and thighs with knees straight (swan dive fashion) five times twice a day. (b) on the back lift both feet with straight legs five times twice a day. (c) Hanging from a bar twice a day if possible. Frequency of treatment depends upon the severity of the pain. A bed-ridden patient I see each day. An office patient I usually see two days in succession to see the reaction to treatment and then two or three times a week until cured. The cure varies from immediate relief to three to six months depending upon the amount of pathology involved. In a good many hundred cases that I have seen in thirty years there have been I believe only two go to surgery. All Rights Reserved American Academy of Osteopathy® GALL BLADDER DISEASE Perrin T. Wilson D.O. There are a great many malfunctioning gall bladders in America, and no doubt in every country where the abdominal muscles are allowed to relax and bulge. The diseased gall bladder runs all the way from failure to empty the bile from muscular laziness or from ptosis, catarrhal congestion, stones, pus, or cancer. In Dr. Still's Research and Practice page 204 he states: "When I am called to a patient suffering with such miseries in the right side in the region of the gall bladder, I lay my patient on his back, flex and bring the knees up far enough to slack the abdominal muscles in order that I may explore in the region of the gall duct for any foreign substances. I will say to the operator that this is no place for gouging with the points of the fingers. If you ever intend to be useful by working in this region with your fingers lay them flat. While you are sitting on the left side of your patient, bring your elbow up towards the patient's right shoulder lay your hand easily on the side of your patient, letting your fingers extend about three inches below the umbilicus . Then with your right little finger back of the lump push it from the gall-duct to the left slowly and easily, holding the little finger firmly to the place. Then bring the next finger alongside of the little finger and firmly hold in place. Then the middle finger, holding it firmly awhile. Then bring the index finger to bear firmly, but gently behind the lump. Each finger in turn reinforcing the first. Be patient, move slowly and give the gall duct time to dilate. About this time the lump will disappear as it enters the intestines." Soon after I graduated from the Osteopathic College, I heard a lecturer ridicule this procedure on anatomical lines. He spoke about the impossibility of reaching the gall bladder or duct. Unfortunately for several years I believed him and thereby neglected to do for my gall bladder patients what I could have done. May I quickly sketch a few cases for you. In 1927 I had a call at a distance which I suspected of being cholecystitis. I sent a young assistant who had just come to me. I told him what I expected and showed him how to treat the woman who was about 40 years of age. On his return he told me that my diagnosis was correct, that she had a temperature of 102 and that it was a surgical case. I asked him if he did what I told him to. He said he had. I then told him I would go out with him the next day, and he could do a blood count. The next day we arrived to see the patient sitting up in bed reading the paper. The temperature was 99.2 F and she reported that about a half hour after her treatment she began to feel better. In the ensuing eleven years I treated her every two or three months. She has never had a recurrence. Another case. Mrs. Merrill had been treated by family doctors, and heart specialists for tachycardia, "Weak heart muscle" and myocarditis. She had taken digitalis about five years and at seventy years of age was more or less of a heart cripple. Examination of the spine revealed Osteopathic pathology at T. 6,7, and 8 much more than at T.3 and 4. The gall bladder seemed to me to be full. X-ray showed no evidence of gall stones but failure of the gall bladder to fill. Treatment as I will explain later was instituted once a week. Within three months digitalis was stopped. She was going up and down stairs as often. as desired instead of once a day and now three years later she tells me that she has had the best year this year for the past ten years. I could go on with case histories but that is enough to show you that a. diseased gall bladder can be reached, stones can be felt through the abdomen and I have known definitely of two cases where I have passed them into the intestines. Furthermore a full gall bladder may be emptied either by getting over it directly or by pressure of the contiguous tissues. Just one more case. Mrs. Adams, age 182 All Rights Reserved American Academy of Osteopathy® 183 70, had been operated on two years previously for intestinal obstruction. She came down with acute cholecystitis with a blood count of 18,000 and a temperature of 102. One of the best surgeons in Boston saw her and said that he wanted the temperature to subside before operating. After two weeks, it refused to subside. I was called in and emptied the gall bladder. In four hours the temperature started down. The surgeon was delighted, and said, "Now take her home, build her up and let me operate before the next attack which will be in less than six months." I have had the woman under my care for two years"seeing her every fortnight. We have had no attack yet. I do not want to leave you with the impression that none of my gall bladder cases are ever operated on, but I use the conservative approach first. In the past fifteen years, I believe only three have gone to surgery while there are close to twenty who have been saved from surgery by, Osteopathic therapy. ... Osteopathic Therapy 1. T 6,7,8,9 and ribs on the right 2. Drain the gall bladder 3. Raise the liver The Patient's Responsibility Adequate rest 2. Mental poise at meals 3. Wear a woolen abdominal band or underwear 4. Have the foot of the bed elevated 5. Exercise and diet When called to see a gall bladder case, the patient may be in such distress that he cannot stay still long enough to apply Osteopathic Therapy. If this is the case, I administer morphine, codein, or pantapon and wait until the pain has subsided enough to permit the patient to relax enough to treat him. In cholecystitis without the presence of cholelithiasis with a stone in the duct it is rarely necessary to use anything. I place the patient on his left side. Standing behind him I put the heel of my right hand on the transverse processes of T 6,7,8,9, allowing my fingers to lie along the shaft of the ribs, with a straight arm attack I gently spring the vertebrae until I feel the whole segment give. Sometimes the area is so tense that it is impossible to get a good release of tissues this way and I apply a more powerful technique as follows: I place my right arm in front of the patient who is still lying on his left side. I grasp his right elbow so that through the leverage of his humerus, I can prevent the upper thorax from being rolled forward. I nestle my right humerus into his groin right up tight against his right anterior superior spine of the ilium. Thus I hold his pelvis from rolling forward. Then with my left hand I contact the left transverse processes of T 6,7,8,9 and reinforce that hand with my chest against it and ask the patient to take a deep breath. The tissues may release just as he lets his breath out. If they do not I give a vigorous thrust. When you are sure that this segment is relaxed turn the patient on the back. Bend his knees up and feel for the stone'. I know positively that I have felt stones in four cases. Two I passed and recovered in the stools. One was too big to pass and was operated on. It was about the size of the rubber tip to a crutch. The other was too big to pass as shown by X-ray. The man is 73 years of age, a bleeder and has had bad reaction to both gas and novocain as demonstrated by extraction of teeth. It was therefore decided five years ago to see what palliative treatment would do. The weight of the stone creates so much ptosis as shown by X-ray that the gall bladder does not empty easily. The man remains very comfortable unless he is on his feet too long at a time. He then gets relief by my emptying the gall bladder. He knows and I know when it empties. When I see him regularly every two weeks he does fairly well. If there are no stones palpable and the gall bladder is full, stretched and ptosed the feel of the tissues are so different from the left upper quadrant that there is no mistaking the presence of pathology. Tenderness varies with the degree of pathology. At the beginning of this paper I quoted Dr. Still's method of moving a stone. This same general procedure I use in emptying the gall bladder of bile or pus. I reemphasize the importance of placing the fingers flat on the abdomen and getting below and lateral to the mass. By squeezing the gall bladder up against the underside of the liver and over towards the center ever so gently, but with a steadily main- All Rights Reserved American Academy of Osteopathy® 184 tained pressure one can usually feel when the mass diminishes in size. Usually three or four attempts are required before satisfactory results are obtained. The patient should get a definite sense of relief. The gall bladder now being drained one can more easily raise the liver itself. I am indebted to Dr. H. V. Hoover to calling my attention to the prevalence of a ptosis of the liver when gall bladder disease is present. It may well be that this ptosis disturbs the drainage of the ducts. The flat of the hand is placed on the abdomen. The little finger and side of the hand parallel to and just below the edge of the liver. The left hand reinforces the right hand helping to sink the right hand into the abdomen and keep it in contact with the liver. Now the patient is asked to take a little breath and then exhale as far as possible. At the time of exhalation follow the edge of the liver up by keeping the side of the right hand in contact and at the point of deepest exhalation tease the liver upward. Repeat twice. Now to - the - patient's responsibility Item 1. I put rest first because it is the thing the patient likes least to do. But in the presence of pathology anywhere in the body adequate rest is essential if the body is to make its maximum repair. If one can lie down for thirty minutes after each meal well and good. At least nine hours should be spent in bed at night. Item 2. Mental poise at meals needs little mention in a group of this nature. I remember a. patient who came to me for gastric distress. I was unable to tell whether it was a pyloric spasm troubling her or a gall bladder spasm, but the reflex in the spine was at T 5 so I always thought it gastric in origin. As long as I treated her every week she got along nicely, but when I tried to lengthen the intervals of treatment back came the distress. One day she said that she was afraid her husband was going to have a shock because his face twitched on the right side. Examination of the husband showed a perfectly healthy man of 55 who had a habit muscular tic of the right side. I suggested that she change her seat at the table so that she could see only the left side of his face, and of course she was reassured about her husband's condition. From then on her gastric symptoms were no longer present. Item 3. I believe it essentiaL to wear a woolen abdominal band winter and summer. A devitalized gall bladder seems to be very sensitive to cold whether from in front of the patient or on the back. Two of the patients that I am following have left off the woolen protection during the hot weather but sooner or later they will have a mild flare up and they will quickly resort to their band. Item 4. As in all cases of ptosis it is helpful to have the foot of the bed raised on four inch blocks. That is not enough to disturb the patient but seems to aid in abdominal drainage. Item 5. Exercise by sitting on a chair or stool and rotating the trunk right and left is very helpful. Also any exercise that will tighten up the abdominal muscles --such as being on the back and raising both feet at the same time or throughout the day remembering to tense the abdominal muscle both sitting and walking. Diet should of course avoid the animal fats especially all pork products. Avoid chocolate and coffee as well as cream. Skim milk because of the presence of large amounts of methionine is beneficial. Much medical procedure on diet is helpful. All Rights Reserved American Academy of Osteopathy® THE PAINFUL SHOULDER Perrin T. Wilson D.O. Dr. Still's 'Research and Practice" p. 361 "In a large percent of neuralgic suffering of the shoulder whether there be swelling or not, I find the outer end of the clavicle pushed too far back." It has been my experience that not only is the outer end of the clavicle too far back, but the whole shaft is not only back but medial. While the position of the clavicle is no doubt the prime consideration in the Osteopathic pathology of the painful shoulder there are other considerations which I wish to point out. Painful shoulder may result' from resting the arm on a high window sill or an auto, lying with arm over the head, exposure to cold, an awkward reach, hanging on a strap in a moving vehicle. This position can easily place the clavicle posterior and medial. If we get a history of direct trauma of any severity of course X-Ray is indicated but here one may at times be misled because I had a case (Mrs. Atherton) who fell to the ground and hit her shoulder (rt) on a stone. It was very oedematous so I immediately obtained an X-Ray which was negative. After some three months of treatment she still could not get her hand to her hair. My Orthopedic consultant felt that in spite of negative X-Ray there must be some rupture of a tendon, because he had seen one previously. Operative procedure revealed a rupture of the supraspinatus tendon near its attachment. It was stitched up and then with Osteopathic care a very good result was obtained. Arthritis and bursitis with or without calcification, neuritis, and myalgia with a history as previously mentioned are by far the most common cause of painful shoulder. While neuritis alone may not cause restricted motion most of our shoulder cases do have restricted motion and my treatment using long lever technique is usually disastrous especially in the acute stage. Dr. John MacDonald, late of Boston, devised a short lever technique which seems to work well and the patient will not be hurt thereby. Let me list the objectives for Ostepathic Therapy in conditions under discussion: 1. Draw C 5 or 6 back in line. 2. Lateral traction on the head of the humerus. 3. Draw the clavicle lateral and forward. 4. Relax the tendon of the Infraspinatus and Terca Minor by deep pressure with the thumb. 5. See the patient daily until the worst of the pain is over--2 per week 'till cured--l to 6 months. The patient should: 1. Wear a sling 2. Relax to the pain 3.Have hot fomentations applied as long and as often as he can get anyone to do it. Or 4. Apply an ice bag. Lie with the arm behind one. About one fourth of these acute shoulders do not tolerate heat. This is noted by an increase of the throbbing pain when heat is applied either by fomentations, a hot water bottle or electric pad. In these cases an ice bag will allay the pain. Now to return to discussion of what we as Osteopathic Physicians can do for this suffering patient. At the Chicago College of Osteopathy a series of lateral X-Rays of the cervical spine was run in cases of neuritis and painful shoulder. These X-Rays showed such a similarity in pattern that since seeing them, I have never failed to look well to the lower cervical. The X-Ray showed a sudden angulation in the natural curve of the neck as if C 5 had slipped forward on c 6 or as though the nucleus pulposus had squeezed anteriorly and caught there--let me illustrate: 185 All Rights Reserved American Academy of Osteopathy® I All Rights Reserved American Academy of Osteopathy® laid gently over the shoulder and reapplied frequently. I doubt if epsom salts add much to the effectiveness of the fomentations. As mentioned before, there is an occasional shoulder that will not tolerate heat. These may be helped by the applica- 187 tion of an ice bag. It is usually unnecessary to instruct a patient how to lie with this condition, they find the least painful condition, but often being on the shoulder with the arm thrown behind the body will be a comfortable way to sleep. All Rights Reserved American Academy of Osteopathy® OSTEOPATHIC MANIPULATIVE SURGERY UNDER GENERAL ANESTHESIA C. Haddon Soden D.O., M-SC. Manipulation under anesthesia to restore normal articular motion occupies an important place in osteopathic therapeutics. Muscular spasticity or contraction is often of such a degree that mobilization of joints cannot readily be produced without the administration of an anesthetic. This method of treatment has been used in the Osteopathic Hospital of Philadelphia for the past 18 years. The older school of medicine has also used joint mobilization under anesthesia, and a report of 200 cases of low back pain was presented in Piersol's International Medical Clinics in 1938. In this series complete cures ranged from 94 to 97 per cent. These figures are in general agreement with our own results. It should be pointed out here as a note of caution that the abolition of protective stabilizing function of the muscles which facilitates mobilization under anesthesia also creates a condition in which the mobilized joint can be easily traumatized if great caution is not exercised. It follows that anyone who undertakes to use this method must be a good diagnostician and a thoroughly competent technician. The importance of the technical ability of the physician cannot be overestimated, and we have seen a number of patients previously treated under anesthesia, who had received no benefit, or were made worse, and in whom later mobilization under anesthesia by us resulted in improvement. Selection of Cases Some of the conditions in which mobilization under anesthesia has produced satisfactory results in our hands are chron ic fibrosis, chronic productive arthritis, such as Spondylosis, Spondylarthritis, Spondylarthrosis, lumbarization, sacralization, selected cases of Paget's disease, chronic disc changes, old compression fractures, intractable brachial, intercostal, or sciatic neuritis, acute traumatic joint lesions, chronic joint lesions, increased muscle tension, thickened ligaments, and traumatic torticollis. In all of these conditions, careful selection of cases is of the utmost importance. The contraindications are very definite. Under no circumstances should patients with the following conditions be subjected to this procedure: Malignancies, fractures, tuberculosis, acute inflammations (diffuse osteochondritis, acute arthritis, spinal cord inflammation), spinal cord tumors, malacic bone disease, primary bone tumors, acute changes in the intervertebral disc, and ankylosls. To this list should be added those cases of cardiac, renal, or other organic disease in which the-shock incident to the procedure might prove injurious. In general patients selected for mobilization under anesthesia are those who have received regular osteopathic manipulative treatment over a long enough period of time to have produced results under average conditions, and in whom no improvement either symptomatic, or in character or range of articular motion has occurred. In testing these patients, the vertebral column appears very rigid and the spinal musculature is spastic. When an attempt is made to produce motion, the rigidity and the spasticity is very much increased. Where this condition does not change. after several treatments, anesthesia reduction is indicated. Why Anesthesia The answer to the question of "Why Anesthesia" lies not only in the successful clinical results, but also in the physiology of anesthesia. According to Dr. William Baldwin (Professor of Physiology at the Philadelphia College of Osteopathy), general anesthesia carried well into the surgical stage causes the abolition of reflex response due to a paralysis of the sensory side of the reflex are, and an accompanying change in the graded synaptic resistance at the segmental levels. There- All Rights Reserved American Academy of Osteopathy® 189 fore, due to the above factors, postural tonus of the muscles is abolished. With the removal of this postural tonus, there is lost, the muscle function of joint stabi lization and the splinting action of the muscles of the joint structures. The loss of these factors of muscular function is desirable in producing joint motion by manipulative procedures, especially when there has been present, previously, a reflexly maintained increase in the postural tonus. In spondylosis there is a calcium infiltration of the para-vertebral structures and in Osteo-arthritis or spondylarth ritis we are dealing with articular changes This calls for elimination of all possible resistance, or the articulation must be in tune as it were to manipulative approach. General anesthesia carried well into the surgical stage abolishes reflex response and removes any impediment to mobilization by manipulation. Under anesthesia there remains only ligamentous action and articular changes to limit joint motion; this enables the physician freely to put an articulation through its normal range of motion, providing restriction adhesions are not developed to the point where they cannot be overcome. Anesthesia Procedures relating to anesthesia for this type of work have been described by Smith who says that cyclopropane is the anesthetic of choice for correction of osteopathic lesions. The average adult patient is given morphine sulphate l/4 gr. and scopolamine l/150 gr. one to two hours before the inhalation of cyclopropane. Cyclopropane Is of such potency that it can be used to produce any depth of anesthesia and permit the use of oxygen in the anesthetic mixture. It is the combination of potency, rapidity of action, lack of irritation to the respiratory tract, and high oxygen content that makes cyclopropane-oxygen an ideal anesthetic in manipulative correction work. The usual objections of its explosive character and inability to use adrenalin with it ordinarily do not have to be considered in work of this type. The rapid induction, adequate relaxation, and rapid recovery with cyclopropane make it an ideal agent in cases such as this where the operative procedure is short but in which perfect relaxation is essential. Ether, so far as the relaxation is concerned, compares very favorably with cyclopropane, but from every other standpoint for this type of work, cyclopropane is to be preferred. The disadvantages of the use of chloroform far outweigh the advantages in this type of work, and Smith sees no reason for using it. Cyclopropane should never be given by other than one experienced in anesthesia, and only with apparatus built to deliver cyclopropane and oxygen. It can be readily appreciated, therefore, that the logical place to administer it is in a hospital where the patient may receive the benefits of a competent anesthetist, suitable apparatus, adequate consultation, etc. These facilities are rarely available in the office of a general practitioner. Anesthesia is carried to the second plane of the third stage. Case Histories I have selected several cases for presentation to illustrate the type of condition treated and the management of these patients. Case 1 - PERITENDONOSIS CALCAREA The patient, male age 53 years, complained of intermittent pain in right shoulder from February 1946 to Dec. 3lst, 1946. The shoulder had not been injured. Roentgen therapy to the right shoulder caused pain to be unbearable. Shoulder joint motion was restricted 80% to 85%. The lower cervical vertebrae were fixed in extension and the upper dorsal vertebrae were fixed in flexion. Roentgen studies 7/2/47 showed a quite large, irregularly delineated opacity possessing a calcium density, manifest within the soft tissues, regional unto the superolateral marginal limits of the capitate portion of the right humerus. This quite large or rather extensive irregular calcification within right shoulder periarticular soft parts possesses the characteristics of an undoubtedly long standing or well established peritendonsis calcarea. The patient was treated by manipulation under general anesthesia (cyclopropane ) 7/4/47. The patient had 75% motion of the right shoulder joint and was prac- All Rights Reserved American Academy of Osteopathy® 190 tically symptomatic free 48 hours after mobilization. . The roentgen study 9/19/47 is reported as follows: Particular attention is directed to an apparent resorption of the previously established large, irregular soft tissue calcification regional unto the superolateral marginal limits of the right humeral head. At present only small and faintly delineated shadows of increased tissue density are visualized in the area of previously recorded large peritendonosis calcarea, this being further appraised as in accord with a most satisfactory therapeutic response. Motion is now restored 97%. A July 2, 1947 B Sept. 19, 1947 Case 2 - OSTEOPOROSIS The patient, female, age 59 years, injured her right shoulder joint, when throwing a cloth up over a clothes line and increased the trauma when she fell in bathroom. B Feb. 23, 1948 All Rights Reserved American Academy of Osteopathy® 191 Upon regaining consciousness her right arm was over the side of the bath tub. An Orthopedic surgeon tried unsuccessfully to restore motion under anesthesia and following this, she had herpes of the right arm, forearm, wrist and hand. The arm was quite swollen. The right shoulder was fixed, motion restricted 75% and the pain was severe, An electroencephalogram was negative. Roentgen studies of right shoulder were negative. X-rays 10/8/47 showed a marked demineralization or osteoporosis of the right distal forearm, carpal, metacarpal and phalangeal structures. The patient was treated under general anesthesia 10/22/47. Results were very satisfactory. Roentgen re-check 2/23/48 demonstrates a now only moderate generalized demineralization or osteoporosis of the right distal forearm, carpal, metacarpal and phalangeal structures. A decided or marked improvement of respective osseous structural density is now established upon comparison with film obtained elsewhere 10/8/47 and submitted, this thereby indicating a generally improved structural trophlcity or trophovascularity. Case 3 - UNI-LATERAL DISCOGENIC RESORPTION OR DISTURBED INTEGRITY OF 5TH LUMBAR DISC. The patient, female, age 39 years, complained of an acute, painful lower back. Continuous pain, posterior aspect of left thigh, resulting from lifting, later on aggravated by tripping over carpet and later on Oct. 1946 falling down stairs. "Recumbent posterior and lateral lumbopelvic film studies obtained demonstrate a quite marked sinistral inclination of the bony pelvis and a concomitant sidebend of the lumbar column, with the vertebral convexity toward the left, reaching maximum proportions in the lower lumbar area. A lumbar numerical variation is determined with six (6) vertebral segments in evidence, while particular attention is directed to a chiefly right unilateral axial narrow or resorption of the 5th lumbar intervertebral disc. This latter 5th lumbar disc narrowing, which is decidedly more marked on the right side, is further evaluated as of a discogenic order, with some marginal productive spondylotic changes located to the anterior and lateral limits of the adjacent surfaces of the 5th and 6th lumbar segments. In accordance with the altered lumbar vertebral alignment, there prevails a slight right unilateral axial compression of the 3rd and 4th lumbar disc structures. Spondylarthrotic reactionary changes attendant upon longstanding physlologic stress and strain are believed to involve the facet joint between the 5th and 6th lumbar segments on the right side, while the lumbar vertebrae are otherwise negative for gross bone or joint pathology. The sacroiliac articulations and, as well, the hip joints are essentially negative and no lytic or productive osseous pathology is observed involving the quite symmetrical pelvis. For purposes of record, it may be stated that the patient's physical status at the time of initial study did not permit oblique film evaluation of the lumbar column. Supplementary anteroposterior and lateral film studies obtained of the dorsal spine demonstrate a moderate compensatory sidebend of the entire dorsal column, with the vertebral convexity toward the right. The mid to lower dorsal vertebral bodies display anterior marginal productive spondylotic changes of a physiologic order, while attention is likewise directed to productive spondylotic changes at the right lateral extent of the adjacent surfaces of the 11th and 12th dorsal segments. The axial height of dorsal Intervertebral discs is generally well preserved and respective vertebrae are otherwise negative for gross pathology. An erect, standing lumbopelvic study secured with some difficulty due to patient's quite marked disability, fails to establish an appreciable deficiency in leg length at film measurement. There is determined a minimal unleveling of the sacral base plane to the left side and a lower lumbar pelvic shift to the left of the midbody gravital line. With patient weight bearing, there is to be emphasized a marked dextral inclination of the mid to upper lumbar column, with some right unilateral axial compression of the-4th lumbar disc and the altered vertebral mechanics appearing to centre chiefly to the level of the 5th lumbar disc, the latter disc structure manifesting the forementioned right unilateral resorptive pathology. The patient was treated under general anesthesia 2/20/48. X-rays 10/3/47 of the dorsal spine records a minimal sidebend of the major extent of the dorsal column, All Rights Reserved American Academy of Osteopathy® 192 Roentgen studies 2/19/47 showed the following: B Feb. 19, 1947 D Oct. 3, 1947 All Rights Reserved American Academy of Osteopathy® with the vertebral convexity towards the right, reaching maximum proportions at the level of the seventh dorsal intervertebral disc. Respective vertebral alignment is otherwise satisfactory and the symmetry of the thoracic cage is preserved. Lumbopelvie structures exhibit some shift to the left of the mid-bony gravital line and there is present a moderate, dextral inclination of the mid to upper lumbar column, the altered vertebral mechanics centering chiefly to the level of the fifth lumbar segment and second lumbar intervertebral disc. PROCEDURE Mobilization under anesthesia is, exclusively, a hospital procedure. It is most Important before the patient enters the hospital, that the physician instruct the patient on the Importance of becoming determined not to fight the anesthetic. This makes for a more smooth anesthesia, and a more successful after-result; in that the majority of the patients take the anesthetic very nicely and come out of it gradually, otherwise, if they struggle during the anesthesia, they will struggle afterward, and this might cause the production of lesions. A complete history and physical examination should be made and a preoperative diagnosis established. When Indicated, gynecologlc, neurologic, cardlologic, myelographic, or other studies should be carried out. Preferably, the patient should be hospitalized the afternoon preceding the operation. General orders to be written include no breakfast, laboratory studies including urinalysis, complete blood count, and serologic tests for syphilis, radiographic study, if this has not been done, and physical examination, including charting of all spinal lesions. The chief anesthetist (preferably a graduate osteopathic physician) evaluates the patient as to the preoperative medication preferred. The routine medication, morphine sulphate grs. l/4, with scopolamine grs. l/150 (for the average patient) is administered one hour before mobilization. The corrective procedure is usually carried out in the anesthesia or operating 193 room, using a regulation treating table. The physician and his several assistants stand to the sides of the patient. The assistants take the pulse, and have the other hand in readiness to place on the patient's arm, in case he struggles. The arms are held against the table, and the forearms (controlled by the other hand) are allowed to move in flexion and extension. The lower extremities are controlled more easily by leaning across them and holding the opposite side of the table. The introduction of the anesthetic agent is continued until the second plane of the third (surgical) stage is reached. 1 - The pulse rate - The rate will increase as the anesthetic is introduced, and the patient is. in the second (excitement) stage. As the surgical plane of the third stage is approached, the pulse rate will become more regular. 2 - The respiratory rate will at first lncrease in rate and amplitude as the second plane is approached. When the patient enters the third stage, the respirations will decrease to a normal rate and amplitude. 3 - When the patient is In the surgical stage of anesthesia, the pupils will be fixed, become small and contracted; the eyeball is fixed and oscillatory motion is lost. 4 - The physician should flex and extend the upper and lower extremities to be sure that there is complete muscular relaxation. Sometimes, in flexing the left forearm, there is complete relaxation, and yet, we find rigidity upon flexion of the right forearm. This is a guide which should be carefully watched as the patient is, evidently, only in the excitement stage. So, the correction is not attempted until the resistance is eliminated, or complete muscular relaxation is obtained. Occasionally, in attempting to, or in mobilizing the sacroiliac articulation, or the fifth lumbar on one side or the other; the patient will become very rigid. Do not attempt any correction at this stage as you can fracture just as easily as breaking a dry twig. The physician must wait, until the surgical stage is again reached and from this point on, mobilization of any or all articulations may be completed.

The right posterior rotation lesion is corrected in the same relative manner with position reversed.

Bilateral Flexion of - the- Fifth - Lumbar - Vertebra The patient is placed in the prone position, the abdomen and chest resting on a pillow. The operator, standing to one side of the table, places one hand over the spinous process of the fifth lumbar vertebra with fingers pointed toward the sacrum. Mobilization is attempted by using a springing pressure directed through the lesioned vertebra in a downward direction and toward the sacrum. Bilateral Extension of - the - Fifth- Lumbar Vertebra The patient is placed in the right lateral recumbent position. The physician, standing in front of the patient's pelvis flexes the patient's left thigh, leg over the side of the table, and hyperflexes both thighs by hyperflexing the right thigh. He places his left hand anterior to the patient's left shoulder and his right forearm posterior to the apex of the sacrum. Mobilization is attempted as follows: The associate keeps springing or hyperflexing the right thigh, while the operator anchors the patient by pressing backward with his left hand and using a springing pressure or a thrust with the right forearm in a forward, upward direction. All Rights Reserved American Academy of Osteopathy® Left Rotation of the Fifth Lumbar Vertebra The patient is placed in the left Simms position. The physician places the thenar eminence of his left hand on the right side of the spinous process of the fifth lumbar vertebra, and reaching over the patient's right leg, places his fingers in the left Popliteal space. The associate presses downward on the right shoulder and scapula with his right hand, controlling the spine in rotation-flexion and places his left hand under the distal end of the left thigh. Mobilization is attempted or Produced as Follows: The associate maintains a downward pressure through the patient's right shoulder and as both the physician and associate flex and elevate the thighs, the physician presses downward through the spinous process of the fifth lumbar vertebra. Rotation of the lumbar vertebrae or lower dorsal vertebrae Is treated the same way, with an increased flexion of the thighs. Left Side Bending of the Fifth Lumbar Vertebra The same technique is used as for rotation, the chief consideration being that pressure of the thenar eminence is down through the spinous process which is to the convex or right side. Lower Cervical, Upper Dorsal Lesions The patient is placed in the left lateral recumbent position. The physician stands in front of the patient, places his right hand under the left side of the patient's head and face and his left axilla over the proximal end of the right arm. Lean lightly on the right arm in order to control 'the dorsal vertebral column. The head and cervical column is held by the right hand in neutral, slightly flexed or an extended position and maintained. Mobilization is now attempted by a combination of elevation (right side bending) left rotation of the head and cervical column and these movements are exaggerated by an upward pressure or traction. 195 The Right Shoulder Joint The patient is placed in the supine position. The physician holds the patient's right shoulder with his left hand, and grasps gently the distal end of the arm with his right hand. While anchoring the shoulder, elevate slightly the arm and release. Try this several times. Slightly abduct the arm and release several times. As a rule this does not produce motion, but seems to be an entering wedge. The patient is now placed in the left lateral position. The physician flexes the patient's right forearm and passes his right hand and forearm under the patient's forearm, the hand up over the right shoulder which it anchors, or protects. The left hand placed on the elbow, presses downward very carefully, releases, then elevates slightly and releases. This is tried several times. Next while protecting the shoulder with the left hand, grasp the distal end of the forearm with the right hand and try to elevate, release, abduct carefully and release. Repeat several times. The right forearm is now flexed and placed very carefully behind the patient's back. The physician places his right hand on the right shoulder his left hand on the elbow and moves the arm slightly forward and backward. During any of these movements, the adhesions give or break. Once the adhesions let go, then increase all physiological articular motions until the shoulder joint is completely free. Hot compresses of lead water and laudanum are applied to the shoulder joint for several days if there is much pain. After one month of rest, from manipulation, careful traction is applied once or twice a week and at the end of the next two months, shoulder motion is at least 97% normal. Summary Mobilization of spinal joints under anesthesia in selected cases has a definite place in osteopathic manipulative procedures. Selected cases are presented. Mobilization under anesthesia is a hospital procedure. Cyclopropane-oxygen is the anesthetic of choice. Manipulative techniques are described. All Rights Reserved American Academy of Osteopathy® SHOE INTERPRETATION--ITS IMPORTANCE TO STRUCTURAL BALANCE C. Haddon Soden, D.O., M.Sc. Normal Weight Distribution In a normal foot approximately 60% of the weight load on a foot is carried by the heel,, and 40% is distributed to the metatarsals or forefoot. The first metatarsal carried about 14% and each of the other metatarsals receive and distribute about 7%. Normally, the first metatarsal is longer and twice as wide as any other metatarsal bone. is again in the same ratio as weight bearing. The first metatarsal carried twice the load of any one other metatarsal, or ratio of 2:l:l:l:l. Pronation (pes planus) will show on the x-ray as a separation between the internal and middle cuneiform bones, with increase in the width of the second metatarsal. Abnormal Weight Distribution In an extreme case described by Dudley J.. Morton in which the first metatarsal is so short that it may not contribute at all to the load of weight bearing, the second metatarsal will then carry about 2 l/2 times its normal load. The third and fourth will carry more than normal, while the fifth may only be bearing 50% of its normal. In less severe cases or a slight shortening of the fifth metatarsal, it may carry half of its normal load, the second twice its amount, the third and fourth about a third more than normal, while the fifth may only be bearing half its load. In cases of pronation, we see that the first metatarsal is again an offender in shifting its burden. The milder cases show the first carrying about l/4 of its normal load, the second twice Its normal, the third and fourth more than normal and the fifth about 59%. In extreme cases of pronation (pes planus) the first metatarsal will carry about 75% of its normal load, the second 2 l/2 times, the third about l/3 increase, the fourth may only carry l/2 of its normal, while the fifth may not carry any load. Roentgen studies of these various types of feet will substantiate the above findings. The metatarsal shortening, and the increase In width of the metatarsals, due to increased weight bearing, can be seen and measured. The increase in metatarsal width is in direct ratio to percentage of the increase in load. Normal width of metatarsal: Shoes The majority of patients never complain of foot trouble, it Is always lower back or back. When asked if their shoes are comfortable, invariably they say "the shoes are the most comfortable, they have ever worn". Do not let this misguide you. Examine all shoes, in order to realize the important role they play in contributing to structural instability or structural stability. The average shoes when viewed externally, look as if they fit the feet properly. It is possible to see the soles need wedging along the medial, or lateral longitudinal arches, and that Is about all. The real story is woven Internally. There one can see depressions and various shades of discolorations on the linings and inner soles, which mean much to one who has the knowledge of interpreting these findings or foot marks. Examination Hold a shoe up to a window, or use a flash light and look inside towards the fore part and side walls for the following: Condition of lining, such as discoloration, depressions, or if worn through. The impression of the toes and their positions on the insole. Indentations or discolorations made by the distal ends of the metatarsal bones. Measure the length of the shoes and the width across the anterior arch. Measure the length and width of the patient's feet when sitting, and standing. When the patient is standing measure as to how far forward metatarsal pads should be placed. 196 All Rights Reserved American Academy of Osteopathy® Interpretation Depressions in the medial or lateral lining indicates shoes should be either an inflare, or an outflare last, and if discolored, or worn through, it gives a greater index as to the amount of pressure being exerted on the side walls. The impressions of the toes, their positions and indentations made by the metatarsal bones will show how the foot distributes its weight load. In the case of an extreme short first metatarsal, the discoloration will be posterior and the greatest indentations will be where the heads of the second, third and fourth metatarsals make their contacts. When the shortening of the first metatarsal is only moderate, the discoloration is less posterior and the insole will show the greatest indentation under the second and third metatarsals. When pronation exists, the impression on the insole will again be greatest where the second and third metatarsal heads press, but the first metatarsal is on the same forward level and the shoe will bulge at the medial border behind the vamp. In metatarsalgia, there is a depression under the first metatarsal bone. In the average shoes, only two toes, the first and second will have space anteriorly, or in the horizontal, whereas the other three are in the perpendicular or pressing against the outer longitudinal wall. This indicates too narrow a shoe and if the first or second toes are pressing well up into the toe-cap they are not long enough. There may be a light or very brown spot on the insole where the metatarsal heads are pressing. 197 convinces the patient as to the importance of shoes. Prescribe proper fitting shoes, and three roentgen standing studies, one in stocking feet, one in original shoes and one with the prescribed shoes, before treating. As a rule, the patient will express pleasure over the change in the lower back since wearing new shoes which is an indication of improved structural stability. In quite a number of cases, the first and third studies show a similar stability whereas the one with improper shoes will show more of a lateral inclination of the femoral weight bearing line, or sacral base, or both with an increased structural instability. When sacro-iliac and lumbo sacral motion is established, add whatever heel lift is necessary on the side to which the sacral base is inclined. In two or three weeks place metatarsal pad l/8” thick (may only be necessary in one shoe) or pads under second, third and fourth metatarsal bones, or use a Dr. Ellis Cuboid pad, or cuboid pads. In metatarsalgia place a small pad one half inch wide, three quarters of an inch long and one sixteenth of an inch thick under the first metatarsal bone. Have shoes conform to the feet, rather than have feet conform to whatever shoes the salesman has on hand. Proper fitting shoes help to eliminate some foot, leg, thigh, hip and lower back troubles in contributing to better structural stability. Summary Make a study of shoes, in order to realize their importance in helping to mainManagement tain structural stability. Show the patient the difference in Roentgen studies show l/4" sacral measurements of the feet while sitting and base inclination (standing 0) in stocking standing, then compare the standing meafeet, and 3/8” sacral base inclination surements with the shoe measurements. This (standing 1) with shoes and increased structural instability.

All Rights Reserved American Academy of Osteopathy® THE OSTEOPATHIC MANAGEMENT OF POST-OPERATIVE INTERVERTEBRAL DISC RETROPULSION C. Haddon Soden,,D.O., M.Sc. We are of the opinion that structural instability is one of the contributing factors to disc retropulsion. It is caused by Improper fitting shoes, hip joint lesions, sacro-iliac lesions, lumbo sacral lesions, lumbar lesions, lower extremity length variations, sacral base lnclinations. musculo-fasciae changes and inelasticity of the ligamentum subflavum. We know from experience, an operation Is necessary to remove the nucleus pulposus which is causing the radicular syndrome, thereby helping the system to now be receptive to Osteopathic manipulation. Therefore surgery contributes to, but does not restore structural stability. Evaluation Before treating the post operative disc we must keep in mind the trauma that has existed for some time, as well as the surgical trauma. Therefore the treatment given in this particular condition is one that is supportive, rather than one which might be too strenuous, thereby aggravating an already traumatized tissue. Examine the shoes very carefully, and prescribe new ones if necessary. Arrange for a standing lumbo pelvic roentgen study, in order to see how much heel elevation is necessary to level the sacral base. Do not prescribe heel lifts until sacro-iliac and lumbo sacral physiological articular motion has been established, as it may produce a greater structural strain, or increase the structural instability. When motion is detected, the structure now has the ability to compensate, and the heel can be elevated. Do not try to mobilize the sacro-iliac and lumbo sacral articulations if there is an ankylosis or fusion. Treatment We use the Soden foot technic and the Still sacro-iliac, lumbo sacral, lumbar and hip lesion technics. Fascia, Muscular, Ligamentous Connections Fibrous bands, or thickened portions of the fascia, bind down the tendons in front of, and, behind the ankle in their passage to the foot. They comprise three ligaments, viz., the transverse crural, the cruciate crural and the laciniate; and the superior and inferior peroneal retinacula. In binding down the flexor and extensor muscles of the leg, and keeping in mind the fascia, muscular and ligamentous relations, throughout the whole structure, we use the foot as a lever, to produce a springing motion through the sacroiliac and vertebral articulation. What effect, from the standpoint of a pump, it has on lymphatic drainage or cerebra spinal fluid flow remains to be proven. Foot Technic The patient is supine. The physician is standing, or preferably sitting, facing the patient's left foot, and places his left hand under the left calcaneus. The tendon achilles is put on and maintained in traction, by pulling caudad with the left hand on the calcaneus. The hypothenar eminence of the right hand, fingers pointing lateralward, Is placed under the distal metatarsal bones, the fingers resting lightly on the dorsum of the phalanges. While maintaining traction with the left hand, the right hand presses upward through the metatarsals (not the phalanges) producing a dorsi flexion, then press lateralward and release to plantar flexion. APPLY this several times, then dorsiflex, press medialward and release. This technic must be smooth and is applied for several minutes to each foot. Only use a very mild dorsi flexion pressure or one the tissue can tolerate. Do not raise the leg, as then the dorsi flexion pressure becomes piston like and traumatizes. Sacro-iliacs Assuming that we are dealing with 199 All Rights Reserved American Academy of Osteopathy® 200 the right anterior sacro-iliac lesion, the patient is lying on the left side in the Simms position, both arms over the sides of the table, the thighs flexed at right angles to the body. The physician is standing back of the patient in line with the pelvis.; he places his left hand posterior to the right ala of the sacrum and places his right hand on the right leg just below the patella. Motion Is attempted or produced by flexing, elevating, and extending the thigh. This procedure is repeated several times. Assuming that the left side shows a posterior sacro-iliac lesion, the patient is lying on the right side, Simms position. The physicfan, standing back of the patient, places his right hand posterior to the left posterior superior-iliac spine, his left hand on the left leg just below the patella. The corrective technic is the same as for the correction of an anterior sacro-Iliac lesion. Lumbo-sacral _ and I Lumbar - Lesions The patient is placed in the Simms position, either right or left side, the physician standing back of the patient, on a line with the patient's pelvis. Assuming that the patient is lying on the right side, the physician places his right hand back of each lesion, and his left hand on the left leg, just below the patella. Motion is attempted or produced by an easy, smooth flexion, elevation and extension of the left thigh. The right hand detects whether or not motion is produced. Flex, elevate and extend the thigh several times. Then the patient is instructed to lie on the left side and the same procedure is used as for the right side. Hip Joint Lesions If the hip joints are lesioned, motion must be established, otherwise it will be impossible to maintain physiological articular motion in the sacro-iliac articulations. -Tests for - Lesions The patient is standing with the feet about eight inches apart; the physician is sitting facing the patient, holding the patient's pelvis. The patient is instructed to evert and then invert first one foot, then the other; the main objective being to notice whether or not inver- sion or eversion is restricted. Technic If the inversion is restricted on the left side correction is made as follows: The patient sitting on a stool,, the distal end of the left leg is resting on the distal end of the right thigh. The physician, facing the patient, places his left hand on the distal end of the left leg, his right hand on the left knee. While pressing backward with the left hand and downward with the right, the patient is instructed to lean forward or hyperflex the vertebral column. This is repeated several times. If, on the other hand, eversion is restricted, the patient and the physician assume the same positions, the only difference in the corrective technic being that the patient leans backward or in hyper-extension. This maneuver is repeated several times. Then, with the patient standing, the physician holds the pelvis and has the patient repeat the inversion and eversion in order to notice how much motion has been established. Sequence of Treatment Acute Stage--Apply foot, sacro-iliac-, lumbo-sacral and lumbar technic twice a week for one month if necessary. Chronic Stage--Apply all three methods once a week, once every two weeks, or less often as the symptoms diminish. Sacral Ease Inclinations--Now that motion is established one of the most important considerations is the sacral base Inclination, which adds to the instability of the vertebral column. Regardless of the inclination of the sacral base line, or the pelvic weightbearing line, whether parallel or contraparallel, the main objective is the vertebra1 column or vertebral balance. If the vertebral column shows no scoliosis, or very little scoliosis, the leveling of the sacral base is not necessary. If, on the other hand, there is a marked scoliosir3, leveling of the sacral base is absolutely necessary, and whichever side the sacral base is inclined towards, that side must be elevated. If the sacral base is inclined inches or more and the patient sits for long periods, for Instance, a typist or auto driver, prescribe a gluteal pad. This aids in stability. All Rights Reserved American Academy of Osteopathy® LECTURE NOTES ON CHAPMAN'S LYMPHATIC REFLEXES C. Haddon Soden, D.O., M.Sc. Dr. Andrew Taylor Still had much to say about the body structure and its fluid parts. Let me quote a few paragraphs that are pertinent to our study of Chapman's Lymphatic Reflexes. The Spinal Cord "To treat the spine more than once or twice a week, and thereby irritate the spinal cord, will cause vital assimilation to be perverted and become the death producing executor by effecting an abortion of the living molecules of life before they are fully matured and while they are in the cellular system, lying immediately under the lymphatics." The Body Fluids "The rule of artery and vein is universal in all living beings, and the Osteopath must know that and abide by its rulings, or he will not succeed as a healer. Place him in open combat with fevers of winter or summer and he saves or loses his patients just in proportion to his ability to sustain the arteries to feed and the veins to purify by taking away the dead substances before they ferment in the lymphatics and cellular system." "Therefore if the dead substances ferment in the lymphatics and cellular system they should have a high place of consideration in our therapy." "The cause of nerve irritation must be found and removed before the channels can relax and open sufficiently to admit the passage of the obstructed fluids." The Fascia -- "As life finds its general nutrient law in the fascia and its nerves, we must connect them to the great source of supply by a cord running the length of the spine, by which all nerves are connected with the brain. The cord throws out millions of nerves to all organs and parts which are supplied with the elements of motion and sensation. All these nerves go to and terminate in that great system, the fascia." "We must remember, as we study the fascia, that it occupies the whole body, and should we find a local region that is disordered, we can relieve that part through the local plexus of nerves which controls that division. Your attention should be directed to all the nerves of that part. Blood must not be allowed to flow to the part by mild motion. Its flow must be gentle. to suit the demands of nutrition, otherwise weakness takes the place of strength, and we lose the benefits of the nutritive nerves." The Lymphatics "The system of lymphatlcs is complete and universal in the whole body. After beholding the lymphatics distributed along all the nerves, blood channels, muscles, glands and all the organs of the body, from the brain to the soles of the feet,' all loaded to fullness with watery fluids, we certainly make but one conclusion as to their use, which would be to mingle with and carry out all impurities of the body, by first mixing with the substances and reducing them to that degree of fineness that will allow them to pass through the smallest tubes of the excretory system, and by that method free the body from all deposits of either solids or fluids and leave nourishment." "Let the nerves all show their powers to throw out every weight that would sink or reduce the vital energies of nature." Therapeutic Secrets "LET US ENTER THE FIELD OF ACTIVE EXPLORATION." Chapman's Reflexes Chapman's reflexes is the term given the hypercongestions manifest by soreness or tenderness at the distal ends of spinal nerves because of the osteopathic physician who discovered and charted their location and therapeutic value in the diagnosis and treatment of disease. These 201 All Rights Reserved American Academy of Osteopathy® 202 hypercongestions vary in size according to location., and to the proportion of pathology present. Dr. Chapman had worked alone with his ideas of lymphatic drainage for about twenty years calling these areas of hypercongestion, lymphatic centers. Chapman charted over two hundred separate and distinct reflexes, each one having a definite and specific effect upon the endocrine. gland or viscus with which it is in association. When he found a given combination of tender areas he always found a given disease entity or organ pathology present, or vice versa with the manifestation of a certain disease entity or pathology there would always be present a definite combination of tender areas. These reflexes are located in the lymphoid tissue in the fascia and are manifested in the acute stage by soreness or tenderness at the distal ends of the spinal nerves. For instance, in the thorax there is lymphcaid tissue between the anterior and posterior intercostal fascia. It is within this tissue that the Chapman's reflex may be found. Each one of you will probably have tenderness In varying degrees at the second interspace. Locate the junction of the manumbrium and body of the sternum at the side of which articulates the second rib below which is the second interspace in which is found, close to the sternum, the thyroid reflex always more or less involved according to the degree of pelvic pathology, bony or otherwise present. The sympathetic fibres we know are passing with the lymphatics which are continuous with those lymphatics of the deeper structures so that treatment of these reflexes or receptor organs will effect all structures so connected. Dr. Owens, who continued with this work after the death of Dr. Chapman, realizing the importance of the autonomic phase, called these areas reflex centers and he has stressed the importance of the pelvicthyroid-adrenal syndrome, or gonad group. So far we know a Chapman reflex lesion is the result of a lymph stasis in the viscus or glands. This lymph stasis is responsible for the dysfunction of that organ or gland. Both the lymph stasis and the resultant dysfunction are reflexly responsible for the Chapman lesion due in part to nerve impulse and to a chemical reaction of the lymphatic tissue in which the reflex lesion is found. Head's law states that "when a painful stimulation is applied to a part of low sensibility in close central connection with a part of much greater sensibility, the pain produced is felt in the part of high sensibility rather than in the part of lower sensibility to which the stimulus was actually applied." Head formulated this law of the location of visceral pain because he recognized two types of sensation in Internal viscera, one in the organ itself which is more that of discomfort and uneasiness and one on the surface of the body which is a true painful sensation. The human body is dependent for the maintenance of its integrity upon the preservation of its structure and its normal chemical balance than the chemical balance is to deranged body structure. To understand Chapman's Reflexes we must have a knowledge of the autonomic nervous system, the endocrine system, the embryologic segmentation and fascia, as well as of the lymphatic system, necessary to work out the pathways from viscus or gland to associated lesions. The significance of these reflex or receptor organs is two fold--they are a reliable index to the nature of the disturbance within their associated organs or glands and they are a specific means of correcting the disturbances. By the stimulation of these receptor organs both the afferent and efferent vessels draining the surrounding tissues will be affected, as will also the entire lymph system of this area. These receptor organs are easy to palpate because of the edema or congestion localized around the area. This method of diagnosis gives an exact picture of the existing condition even to the extent of involvement, and treatment, correctly applied, usually obtains the specific results desired. A bony lesion may be primary or it may be secondary to some functional disturbance. Any lesion which disturbs the bony pelvis interferes with the blood and nerve supply to the gonads which in turn directly affect the thyroid, whose function it is to influence the oxygen content of the blood. All the blood passes through the thyroid gland at least twice an hour and there receives thyroxine, the secretion of the thyroid, which is carried to All Rights Reserved American Academy of Osteopathy® 203 every tissue cell. Thus with a pelvic lesion is started the imbalance to the endocrine system which in turn interferes with nutrition to body structures. Result--impaired function of gland or viscus and possible further result--bony lesion. This is the reason that no attempt should be made to correct bony lesions until the corrected nutritional disturbances responsible for the pathology nave been re-established at the site of such lesions. Frequently by that time the lesions will have disappeared or their correction will be a very easy accomplishment. And because of this removal of tissue pathology at the site of the bony lesion that lesion when corrected will stay corrected. This point has been experienced by many Osteopathic Physicians especially in the treatment of chronic conditions that manipulative treatment will add to the discomfort of the patient and to the severity of the condition. This happens because of a lack of understanding of the need for the removal of the underlying tissue pathology before the attempt of bony correction which oft times aggravates a chronic state causing still further stasis of body fluids. Equally important in this connection is the fact that corrective work before the nutritional change has been re-established is apt to dissipate the effect of the reflex work or at least tend to obscure the usual spectacular results.

Place heel of right hand against the front of the anterior superior spine, left hand back of the tuberosity of the ischium, with patient's knee against your abdomen. Exert equal pressure with both hands, 'pushing away from you with right hand and pulling toward you with left hand. Left Anterior Rotation - To correct a left anterior rotation place patient on right side. Place the left hand in front of the anterior superior spine and right hand back of the ischium, with patient's knee against your abdomen. Exert equal pressure with both hands, pushing away from you, with your left hand pulling toward you with right hand. Ma1 Position at the Symphysis - When the innominate is down at the symphysis, place patient on back. Stand opposite side of table from the lesioned innominate. Flex the leg on lesioned side and bring it toward you across the patient's body at an angle of 45 degrees. If it is a right innominate down place your right hand on patient's knee and your left beneath the tuberosity of the ischium. Bring the leg on lesioned side toward you and press down on the knee to spread the sacral articulation and lift with your left hand on the tuberosity. If it is a left innominate that is down, stand on right side of table and with left hand resting at patient's knee and your right hand beneath the patient's tuberosity bring the leg on the lesioned side toward you and press down on the knee to spread the sacral articulation and lift with your right hand on the tuberosity. If either innominate is up at the symphysis place patient on opposite side from the lesion. Stand behind then 'slip your arm between the patient's thighs and grasp the top side of the lesioned innominate, with the weight of patient's leg rest- ing upon your arm, pull down with the innominate-engaged hand and push forward with your free hand against the posterior superior spine. This will easily rotate the joint into position. Once the pelvic lesion has been detected and corrected attention should be turned to relieving the congested lymphatic drainage. In order to more readily visualize and remember the reflex centers I have! filled them in on the charts, starting with the Eye, Ear, Nose and Throat, Respiratory, Circulatory, Digestive, Glandular, etc. In order to get the maximum results, always treat the sacro-iliac lesion, and then if it is, for example, a digestive disturbance, treat only the involved digestive reflex centers. If respiratory, treat the sacro-iliac lesion and the involved respiratory reflex centers etc. Relaxing the Thorax - The patient is prone. Place pillow under the patient's chest and one under the frontal bone, arms hanging loosely on either side of table. Place thumbs above the ribs lateral to the transverse processes of the first dorsal vertebra on either side using heavy pressure. Have patient extend or swing his arms toward the head of the table and inhale. On reaching the limit of extension have the patient exhale and return arms to their original position, move the thumbs to the same position 2nd dorsal vertebra and proceed as before, vertebra by vertebra until the entire thorax has been relaxed. This method of relaxing the thorax, stimulates the sympathetics through the splanchnit area, expands the chest and lungs, and if vertebral or rib motion are present, it makes their replacement much easier to accomplish. Warning - Prescribe a plain water enema before retiring, as the detritus, present in the colon will cause the patient to become very toxic if not removed.

No skill has been developed without patient, persistent effort on the part of the individual who has determined to master the fundamentals and applications of the principles involved. In the practice of Osteopathy this is all too true. To one who would practice manipulatively it is essential that one understand (1) the anatomical, physiological, and pathological relations of the human body; (2) that he properly correlate these with the signs and symptoms he elicits; (3) that he apply specific treatment in accordance with his findings and therapeutic aims; and (4) that he develop palpatory and manipulative skills that will enable him to achieve his objectives in treatment. The normalization of Osteopathic lesions has long been a prime objective in the restoration of the body to health. Much time and effort has gone into this project since Dr. A. T. Still first pronounced the system of therapy called Osteopathy. There is no doubt but that Dr. Still was very specific in his treatment of lesion pathology, and indeed the progress of Osteopathy has been dependent upon the ability of his students to duplicate his work. The Chapman reflexes form a very important part of the lesion pathology picture, both from a diagnostic and therapeutic aspect. I. - Research in the Chapman reflexes has been a very real problem. It has been extremely difficult to map out a rational approach whereby these reflexes can be demonstrated and proved. To date we have only the clinical results of the application of the reflexes discovered by Chapman and promulgated by Owens for the raison d'etre of this therapeutic effort. II.-The anatomical dissection of the Chapman reflex manifestation anteriorly by Small in 1937 at The Chicago College of Osteopathy has been duplicated at The Philadelphia College . As yet tissue specimens from cadavers on which the clinical and pathological diagnoses have been made have not been obtained. No doubt this will be part of the program of research. It will serve to link definitely the relation of organ to specific reflex center. Of utmost importance is the fact that for each organ the anterior lesion is always found in the same relative position. This consistency of reflex pattern insures the value of these reflexes from a diagnostic viewpoint. In addition, the anterior centers are sufficiently widespread so that confusion as2to which organ is involved is eliminated. The anterior reflex center may range in size from that of a small pea to several inches in length in the adult. It is characterized by a peculiar granular feel of the underlying tissues of the skin to extremely light palpation. In some cases the center may feel almost edematous. There may or may not be pain in connection with palpation of the center. The intensity of pain denotes the relative amount of involvement of the related organ. The complete lack of pain denotes a process of long duration and very marked involvement. The anatomical pathway over which the reflex is manifested is probably the sympathetic division of the autonomic nervous system. These reflexes are not to be confused with the reflexes of referred pain. III.-The physiology of the Chapman reflex is open to study and to constructive criticism. One must remember that clinically it is operative. Since Chapman theorized that lymphatic stasis in an organ produced the irritation which set off the reflex phenomenon and demonstrated clinically the reversibility of the pathway thru which the reflex was mediated, one must ponder the question as to how the stasis of lymph could occur. (a) The imbalance of the pelvis associated with the imbalance of the endocrine system may result in a state of imbalance between the autonomies and the endocrines, or in other words a neuro-chemical clash by means of which susceptible organs may become involved. 212 All Rights Reserved American Academy of Osteopathy® (b) Toxins and/or other substances noxious to the contractile and permeable elements of the capillaries may so alter their caliber and permeability that lymphatic stasis may be induced. Much of the water from the tissue spaces is absorbed by the venous capillaries. The lymphatic vessels being more permeable, absorb both water and the protein elements from the tissue spaces. Since the noxious agents usually increase the permeability of the capillaries there is a tendency for an increased amount of protein to be filtered thru into the tissue spaces, thus placing an increased absorptive load upon the lymphatics. This lymphatic stasis or inflammatory edema is localized to an area of varyi s g extent surrounding the injured area. (c) Neurotrophic disorders may affect the caliber of the capillaries, thus affecting their permeability. The capillaries can and do contract independent of the arterioles, and they have been observed to resist an arteriolar pressure of as much as 100 millimeters of mercury. They receive efferent fibers from the sympathetics and stimulation of the sympathetics may cause changes in the size of the capillaries without regard to changes in the arterioles. Afferent fibers of the sympathetics come down as far as the arterioles, some ending in Pacinian bodies.4 These neurotrophic disorders may be and probably are induced by Osteopathic spinal and cranial lesions. It may be reasoned now, that with irritation in a viscus involving the capillaries and the lymphatics, impulses may pass upward to the spinal cord either antidromically along the efferent pathways, or directly along the afferent pathways, or both. Having reached the central nervous system, this abnormal bombardment of impulses probably follows a somatic course outward into the cutaneous site of the Chapman reflex center, where an active process is instituted, creating the phenomenon before described as the anterior reflex center. Since stimulation of the sympathetics will cause independent contraction of the capillaries in experimental animals,5 so too, will stimulation of the Chapman reflex center cause changes in the capillaries of the viscus associated with this facilitated reflex pathway. 213 Now let us proceed to the clinical aspects of these reflexes. I want you to pay particular attention to Dr. Mitchell as he presents the crux of the Chapman reflex treatment--the balancing of the bony pelvis. Upon this delicate balance depends a large share of the effectiveness of a reflex treatment. If the pelvis is not balanced properly, a large part of the reflex treatment is nullified. If the pelvis becomes unbalanced, as it frequently will, signs and symptoms will return. It is not always possible to balance the pelvis and have it remain in balance from the first treatment on. Oftimes the pathology is so severe that it tends to unbalance the pelvis. Sometimes it may take several weeks before the pelvis remains in balance. This is a particularly trying period, as symptoms tend to recur. The balance of the pelvis is one of the criteria of the progress of the patient and his treatment. The diminution and disappearance of the involved centers are further criteria of progress. As one progresses in the administration of the Chapman reflex treatment, he observes that for certain conditions there is a striking similarity in the pattern of the reflex centers involved. Since only those centers involved are to be treated, this lends specificity with a capital "S" to one's treatment. It is as specifically measured as a dose of medicine. One notes too, that he tends to interpret his findings as groups of organs, a departure from the usual forms of diagnosis. The Pelvic-thyroid syndrome, the imbalance between the structural pelvis, the gonads, and the thyroid gland is a constant pattern. In the analysis of such a clinic: al problem as peptic ulcer, there Is a pattern of reflexes as follows: pelvic-thyroid- syndrome--basic; gonads, gastric hyperacidity, gastric mucosal congestion, phlorus, duodenum--characteristic. In mucous colitis or spastic constipation there is: pelvic-thyroid syndrome--basic; gonads, spastic colon, torpid liver, gallbladder, duodenum--characteristic. In bronchitis there is: pelvic-thyroid syndrome-basic; bronchial, upper and lower lung centers, groin gland centers, spleen, panThere are many creas--characteristic. other stable patterns of which these are but a few. The role of the pancreas is little All Rights Reserved American Academy of Osteopathy® 214 known in the various disease problems which we are called upon to treat generally. However, there is a direct relationship between the pancreas and these various diseases, and the pancreatic reflex is nearly always the last to clear up. There. is also a direct relationship between the pancreas and adrenals, and these two are frequently associated in lesion patterns. When one has spent considerable time in study of the Chapman reflexes, and has spent many hours in perfecting his technique and in observing these patterns as well as his clinical results, he arrives at conclusions concerning the intimate relationships existing between the functions of the various organs of the body. These conclusions are not always in keeping with some of the present day accepted theories, but they are strong circumstantial evidence, and in action upon them, one is gratified by some very startling clinical results. I should like to bring to your attention the Evans mesenteric flush technique.6 This is a lymphagogic stimulant, in that a fairly large quantity of isotonic saline is administered. This isotonic saline increases the flow of lymph. It is especially helpful in acute infectious diseases.. After the initial examination, it is possible to balance the pelvis and administer a Chapman reflex treatment in from six to ten minutes. One does not dwell upon the Chapman centers except with a light touch and for not more than ten to fifteen seconds for each center. More Chapman treatments have been nullified by gouging at the centers with a heavy finger for too long a time than by any other error. I should like to conclude by telling you of the treatment of one clinical picture. That is the menopausal syndrome, and I have chosen it because of its dra- matic results. The centers treated are: pelvilcthyroid syndrome--basic; gonads, ovaries, adrenals, spleen, pancreas. The patient is treated about three times a week for two weeks, which is usually sufficient. Usually after the first or second treatment the patient is completely relieved of all untoward symptoms. However, because of this, the patient usually engages in a great deal of strenuous physical effort, which promptly unbalances the pelvis. The symptoms return at once. The next treatment corrects the pelvis, again, and �by the end of the second week the pelvis will usually remain balanced for a long period of time. After a course of treatment so described, I have had patients remain free of symptoms for periods of from six months to more than a year without further treatment. It requires a great deal of time, patience, and study as well as practice to become proficient in diagnosis by means of the Chapman reflex centers and in the administration of the Chapman reflex treatment. The routine of the treatment is outlined in "An Endocrine Interpretation of The Chapman's Reflex' by Charles Owens, D.O. One cannot sit down with the book and be able to administer a reflex treatment. He must apprentice himself to someone who has mastered the work, then return to his book from time to time to assure himself that he is not adulterating his reflex work with the addition of other bits of therapy which may nullify its good. The Chapman reflexes are no better than the intelligent application of their principles; they are delicate and will not stand alone without causing an untoward . reaction in the patient; they are worth all the study one is willing to devote to them.

During the past few years, many articles have been written about postural balance, and many lectures given on the same subject, but all of those which I have read or heard seemed incomplete. They have not included all points which are necessary to give the entire picture. As I see it, structural analysis is a vital part of osteopathy because it is one of the fundamentals of basic osteopathy. And yet, structural analysis is not complete unless you can visualize what connection there is between what you find and the patient's symptoms and complaints. Therefore, I would like to explain to you, what I feel, are the basic points of such structural analysis. They are eight in number: (1) Shoes; (2) Feet; (3) The ankle joint; (4) The Knees; (5) The hip joints; (6) The pelvis; (7) The Lumbosacral articulation; and (8) The spine and upper structure. Following is the breakdown of each, starting at the bottom or foundation and working up. The first is shoes: These play a very important part in our everyday lives, much more so than the average person or doctor realizes. We have many different kinds of shoes: in fact, in the United States today, there are twelve hundred and eighty six different makes of shoes, so it is a difficult task for any person or physician to analyze all makes of shoes and select those which they feel are the most important types of shoes for people to wear. But let us consider the different types of shoes. Beginning with the women's shoes, the first type for consideration is the health shoe. The health or orthopedic shoe should be made of leather and have a large leather heel not over l-1/2" in height with a walking surface the size of a silver dollar. This shoe is an oxford usually having six or seven eyelets and a round toe. It has a high-fitting quarter and is made in a combination last of at least three widths difference between the forepart and the heel. It has a very strong shank, as well as a good heavy in- sole and outsole. The second type is a Semi-Style type of shoe. This type has a heel ranging in height from twelve-eighths to sixteen-eighths, or one-and-a-half to two inches in height with a walking surface usually the size of a quarter. It is an oxford generally having four or five eyelets, with a high-fitting quarter pattern and a pointed toe, with thinner insoles and outsoles than the health shoe and carries a semi-rigid type of shank. This shoe tries to combine the main features of a health shoe as well as the style pattern of the style shoe. The third type is the style shoe. This type of shoe generally has from a sixteen-eighth to a forty-eighth heel height, or from two to six inches in height and has a walking surface no larger than a nickel. This shoe is seen as 'a heelless or toeless shoe, as well as a Pump. These shoes must be fitted short in order to keep the heels on. This type of shoe is always pointed, and in the toeless shoes, the opening is placed in front of the third toe and causes the woman to push her big toe out through the opening so she can say that she is wearing a much shorter shoe than she normally should be wearing. This shoe also has a thin insole and outsole, with a semi-rigid type of shank in the shoe. Then there is the fourth classification that has been introduced during the past few years, and this is the shoe called the "loafer" including sandals and huaraches. This type of shoe has absolutely no support, little or no heels and allows the foot to be sloppy, which is just the way the shoe looks. In men's shoes we have three classifications: We have the first type, which is the health shoe or everyday type, made up with the large type of men's heel using six or seven eyelets in a high-fitting quarter, a medium to wellrounded toe, and has a heavy insole and outsole as well as a very rigid shank. 215 All Rights Reserved American Academy of Osteopathy® 216 The second type is the style type, which is made up of almost the same characteristics as the health shoe with the exception that it is pointed or superpointed or with a heavy overlay of leather for creating the style pattern, such as the "wing-tips". Many of these carry a semi-rigid shank and thin insoles to help give them a neater appearance. The third type is the "loafer" type, wherein again we find men wearing loafers, sandals or slippers. We must consider shoes as the fundamental part of our problem, for all people wear shoes the greatest majority of hours that they are up and about. Therefore, any irritations that are set up by the shoes, can create reflexes in the feet which may produce many diseases. so it is up to you, as osteopathic physicians, to include shoes as part of your armamentarium, prescribing the use of proper shoes to all your patients to make sure that these reflexes are not in existence. Generally speaking; we are unable to normalize the function of a broken down or weak foot, so we try to do the. best we can by approaching normalcy through the use of manipulation, shoes, strapping and padding. In this way we can eliminate the reflexes which are producing many other ailments in remote parts of the body. What is most vitally important to all of us, is your recommendation of the proper shoes for the children who are your patients and friends. It is up to you, if you are a real physiclan to make sure that these children's feet develop normally. It is up to you to make sure that they wear the proper type of shoes, and in this way, their feet will be normal feet when they become adults, instead of finding as we do today, 85% of all adults having foot trouble. My- recommendations are that you keep all children in oxfords or the 3/4 height shoes (this shoe divides the height between an oxford and a high shoe--the top fits just to the ankle bones.) The reason why we make this statement is that high shoes definitely weaken feet and prevent the norma1 development, of feet. Observe the next child who comes into your office wearing a pair of high shoes. Notice the atrophy of the fat and the muscles under the high top shoes and how the flesh bulges out over the top of the shoes. This is why you must recommend oxford type shoes to these children's parents. Please help to keep normal feet developing normally! The second point is feet: In the foot we have twenty-six bones which for the sake of foot function can be divided into an important and unimportant groups. The important group is the OS calcis, cubold, talus, the three cuneiformes, and the navicular or scaphoid. The unimportant bones are the five metatarsals and the fourteen phalanges. It is necessary for each of us to understand the normal positions, as well as the abnormal positions of the bones of the feet in order that we may judge when we have structural balance within each foot. Therefore, we will try to give to you what we consider the normal positions of the bones of the feet, and tell you what happens when they go into lesion and form the various types of foot defects. To start with, we analyze the feet by having the patient stand in his bare or stocking feet so that we can see the position of the tendo-achilles. We watch especially the medial side, as in a normal foot this tendon is straight up and down. The more. convex it becomes on the medial side, the greater the weakness shown in the arch of the foot. We term these weaknesses in this manner: First degree, second degree, third degree, and fourth degree or totally flat foot. We also must ascertain the difference between the norma1 type of foot and the weakness of a higher arch, and this is done along the same manner. In other words, by holding up the inner longitudinal arch until the medial side of the tendo-achilles is in a straight line, we are able to judge the normal height of the medial longitudinal arch. When we allow this foot to relax and it pronates, then we are able to conelude the amount of weakness as this medial longitudinal arch drops. We find in our 'practice and research that high arches make up 90% of the people's feet which we examine, 5% in the medium-height normal arch, 3% to 4% in the normal low arch,, and from 1% to 2% in the normal flat foot. This works in the reverse ratio as to the weakness of feet, for the strongest foot is the normal flat foot, and the weakest type of foot is the high arch. Now let us take into consideration the bones of the feet in the order of their importance: In my opinion, the cuboid is All Rights Reserved American Academy of Osteopathy® the most important bone in the foot. The reason why, is this: On the postero-inferior aspect and on the medial side of the cuboid, we find a prolongation of bone with a facet which articulates with a facet of the OS calcis. Therefore, when the cuboid is in Its normal position, it holds the OS calcis in its normal position as well as the cuneiformes and the fourth and fifth metatarsals, then we have definitely a normal foot. But, when the cuboid goes into lesion and rotates inwardly and downwardly, it allows the OS calcis to change its position and thus we have the start of a weak foot. It is easy to detect a cuboid lesion by observation and by examining the foot. On observation, when we see a dropped fourth metatarsal bone and a rotated and upward-thrust fifth metatarsal with the styloid process very prominent and with the little toe riding up in the air similar to a hammer-toe and sometimes over-riding the fourth toe, we can be sure this cuboid is in lesion. On examination when we palpate the inferior medial aspect of the cuboid which is found halfway across the foot from the posterior aspect of the styloid process of the fifth metatarsal, we know that the cuboid is in lesion. The cuboid is also the base of the so called posterior transverse arch, and as long as the cubold is in its normal position, it definitely holds up the external, middle and internal cuneiformes so they can function normally in holding up the metatarsals to which they articulate. The next bone of importance is the OS calcis, or the heel bone. This bone normally carries approximately 60% of the body weight in its static form. It has its normal axis and position, which we have already explained, by examining the inner side of the tendo-achilles. We have also explained that the OS calcis does not go into lesion until the cuboid has gone into lesion. When this happens, we find one of two lesions taking place in the OS calcis. The first type, which we find more frequently is the inversion or pronation of the OS calcis. This lesion gives us the commonly called weak arches or flat feet, The second lesion is when the OS calcis drops straight forward. This lesion causes a change in the triangular weight fulcrum and causes the weight to be shifted forwardly and the results are a slapping foot or the forepart of the foot 217 hitting hard in walking. The next bone of importance is the talus or astragalus. Its importance comes from its transmission of body weight as it comes down through the tibia and fibula, and then transmits it through Its facets to the other bones of the foot so that all parts of the foot are carrying their normal amount of weight. As we discern in the skeleton foot, these facets are heaviest in the direction of the greatest amount of weight flow. We observe on its lnferior aspect a large facet transmitting approximately 60% of the weight (considering each foot as a 100% unit) to the OS calcis. We note the next largest facet articulating with the cuboid as it in turn transmits the weight toward the styloid process of the fifth metatarsal and the heads of the fourth and fifth metatarsals. This directional weight thrust transmits about 30%. We see a large facet articulating with the navicular or scaphoid and dividing the weight thrust of approximately 10% through each of the cuneiformes and on to the heads. of the first, second and third metatarsal bones. Those percentages are for the static or stationary foot. When the cuboid and OS calcis are in normal relationship with the talus, the talus holds a normal position and transmits body weight in its normal lines. But when we discover a cuboid lesion, we note an inward or outward rotation of the talus. The Inward rotation causes the weight to be switched from the outer side of the foot to the inner side of the foot, and we eventually note that the person starts turning his entire foot laterally. The outward rotation causes the weight to be shifted more laterally and results in an excess of weight to be carried and in many cases simulates a pes cavus foot. The three cuneiformes are next in importance, for their normal position depends greatly upon the normal position of the cuboid. When it rotates inwardly and downwardly, it takes the base of the transverse arch out from under it, thus allowing the external or middle cuneiforme to drop downwardly and the inferior cuneiforme to rotate inwardly and downwardly. When this takes place, the external cuneiforme when in lesion allows the head of the third metatarsal to drop, the middle cuneiforme allows the second metatarsal to drop, and the internal cuneiforme when it rotates, All Rights Reserved American Academy of Osteopathy® 218 allows the first metatarsal to rotate also. The continued amount of rotation of the first metatarsal and the subsequent muscular pull causes a dislocation of the metatarsophalangeal articulation. This is the hallux valgus or the, commonly called, bunion. Last and least significant of the important bones is the scaphoid or the navicular. This bone acts as a ball and socket and its position follows the weight thrust as ascertained by the other six important bones, but more especially that of the talus. This can be seen easily on the examination of the skeleton foot and noting the type of facets or the shape of the bones. The unimportant bones of the feet are the five metatarsals and fourteen phalanges. The reason we say that these are unimportant, is due to the fact that their normal position depends almost entirely upon the position of the significant bones of the feet and especially the cuboid and three cuneiformes as previously described. Most of the metatarsal pain which is found, has been attributed to a breakdown of the important bones of the feet with the exception of a patient, who wears shoes which are too short, too narrow, too pointed, poorly constructed, the wrong type of shoes and also who wears hose that are too short. This is creating a breakdown by external force. Our next point is the ankle joint: In this we include the articulations between the tibia and fibula and the astragalus or talus. There are two types of lesions in the ankle joint which we note, one of which we have already described-rotation of the talus which in turn creates a lesion between the talus and the tibia. The second lesion, which causes much more damage, and which today we are finding so prevalent, is the posterior deflection of the tibia on the talus, thus causing an alteration in the weight thrust from its normal fulcrum in a posterior direction, and so, creating a slapping foot. The fibula, when in this lesion, usually drops downwardly and forwardly and this lesion is dependent on muscular pull and its action from the cuboid, for it is noted that whenever we have a cuboid lesion, the head of the fibula is always posterior. Our fourth point is the knee joint: This particular area is one point over which much controversy rages. The reason for this is the fact that too many of our anatomists have given us the anatomy of the knee joint and proved to us that we have seventeen ligaments in the knee joint many of which hold the cartilages or menisci in their normal position. But when we palpate these knees and feel a lump at the articular surface, we are not feeling the menisci but a swelling in the articular capsule. I have taken care of quite a few thousand football players and in all my years of experience, I have seen only three cases in which I have been able to palpate the menisci, and in each case the knee was severely torn and it was necessary for the patient to submit to surgery. In my opinion, whenever you tear a cartilage loose , you have torn the ligaments so severely that nature will not heal them in their normal position, consequently, surgery must be employed for correction. Very frequently, I have had cases where examination revealed there has been a rotation of the tibia on the femur, thus creating a smaller articular surface which, therefore, does not allow the knee to go through its normal range of motion. A second lesion, we encounter, is the rumpling of the cartilage itself either forwardly or backwardly and so creating a limitation of motion in the knee joint due to these high spots that are created by the compressed cartilage. Later we will demonstrate a technique which we have used for many years in the correction of both those lesions; for if you have one or the other, the same manipulation will correct either one. Our fifth point is the hip joints: It is very essential for us to consider the hip joints in postural analysis due to the fact that we do find a change in the normal angulation of the neck of the femur. This may be slight or it may be exaggerated, but any difference in the normal angulation of the neck of the femur will definitely produce a short leg on the side of the lesion. So, in x-rays, taken of the pelvis and hip joints, it is very important to include the neck of the femur so we can determine whether there is any difference in the angulation. Our sixth point is the pelvis: The pelvis itself must be taken First as an entire entity, and next divided into its component parts. We must analyze in our All Rights Reserved American Academy of Osteopathy® 219 own mind on examination whether or not to have an anterior, posterior, or a combination antero-posterior lesion of the ilia. We must also take into consideration any rotations or deviations of the sacrum. It is imperative for us to consider the deviations as created by the lack of motion through the axis of the sacrum in its relation with the cranium. I might further explain that the axis of the sacrum runs between the second sacral segments, and on inspiration the sacrum goes up and back, on expiration it goes down and forward. We make this diagnosis by having the patient lie face down on the table, and then with our fingers placed on the base of the sacrum and the apex of the sacrum, have the patient take a deep breath and exhale. If the sacrum does not rock on its axis, then we know that there is a cranial lesion. When it does rock, but is restricted in its joint facets, we know then that it is a sacroiliac lesion. The sacroiliac facets are "L" shaped so there is a possibility for us to have a variety of lesions or limitations of motion in this articulation. We may have a limitation of either of the upper poles or the two lower poles or any combination of both upper or lower and an upper on one side and lower on the opposite or the two upper and two lower poles. We can have also an anterior or posterior deflection of the sacrum thus causing a posterior limitation of motion on the upper poles and anterior limitation of motion on lower facets. Thus in good diagnostic procedure, it is most important to do the best job to get best results for the patient, and one must definitely analyze this articulation to determine the type of lesion that is found so it can be accurately corrected. The seventh point is the lumbosacral articulation: This articulation is fundamental as It is at this point that there is a transmission of the weight from a singular structure (the spine) to a larger or diffuse structure for the transference of the weight thrust down both legs into the feet. We note that in lesion at this articulation, the fifth lumbar must first go anterior before it rotates. This is quite significant, for in postural analysis in order to help us analyze what has taken place at this particular articulation, it is necessary for us to make sure that we do a standing lateral X-ray. The eighth point is the remainder of the spine and upper extremities, which many men have talked and written about. Therefore, we will not include an explanation here, but we would be willing to show technique of any of these articulation if you so desire during our manipulative phase of the evening. At this point, I would like to explain with the aid of our charts what we mean by postural integrity. This commences, as you will note in the first chart with LATERAL ASPECT ANTERO POSTERIOR ASPECT CENTER OF GRAVITY FALLS� MIDWAY BETWEEN ANKLES GRAVITY LINE PASSES THRU ASTRAGALO SCAPHOID JOINT Figure 1 the normal position of weight balance as It is transmitted through the posturally perfect individual. As you will note, we find the feet in straight alignment with the ankles, knees, hip joints, lumbosacral articulation, the square hips, the square shoulders, and the straight head. In the lateral view, we note that the center line of gravity passes through the astragaloscaphoid joint, through the knees, the hip joints, the shoulder joints, and the occi- All Rights Reserved American Academy of Osteopathy® 220 pita1 articulation--thus giving us a posturally perfect individual. But then what happens. First let us consider the differences in postural alignment attributed to many different defects in the developmental growth of the Individual or injuries which create an anatomically short leg. We have found, through our years of work and research, that 60% of all the people we have examined in schools, colleges, lecturing to luncheon groups, as well as our own practice, have short legs and this figure has been upheld by those figures found by other schools of practice. By the next two charts we will show you what happens. In the first place, we ALTERED LATERAL EQUILIBRIUM SINGLE TOTAL CURVATURE SCOUOTIC CURVATURE ALTERED LATERAL EQUILIBRIUM GROSS SCOLIOTIC CURVATURE GRAVITY LOAD DEFLECTED TO LONG LEG Figure 3 Figure 2 can have one leg shorter than the other and still have the center line of body weight held equally between our two feet, and have what appears to be normal feet, but we see a difference in the heights of the hips and in some instances, a difference in the heights of the shoulders as well as some who have square shoulders. The defect discovered most frequently was termed as a function curve of the spine. Then we must take into consideration those people who compensate for the defect of the short leg. In a single type of total curvature, this type of individual having a short leg (let us say on the left) has the greatest amount of weight projected on the long leg, thus creating an inversion of the right foot and an eversion of the left foot. We also find a compression on the outer side of the right knee and the medial side of the left knee. We will also note a difference in the heights of the pelvis, with the right side high and the left low. Usually in this type of case, we find the shoulders will tip in the opposite direction, the right shoulder being low and the left high, and the head is tilted toward the high shoulder or to the All Rights Reserved American Academy of Osteopathy® short side. In the scoliotic curvature, we note some changes in this, but the main change Is found in the amount of curvature to the spine, for as in the single total curvature type, we find a greater amount of the weigh being thrust on the long leg, and again the inversion of the right foot and eversion of the left. The same compression in the knee exists, the same change in the heights of the hips, the right being higher than the left with a side sway toward the left or short side. We also note a greater curvature, which usually is of an "S" type, with the right shoulder low and the left high, and again the head is tilted toward the high shoulder--but It rotates toward the low side. In the gross scoliotic curvature, our best explanation of this condition, is that nature has compensated. It compensates by shifting the body weight from the long leg side to the short leg side, and in this case we see an eversion of the foot on the short leg or left side, and inversion of the right foot; the same type of compression at the knees on the inner side of the short leg and outer side of the long leg; a low left hip with a side-bending to the long leg side; with the corresponding low right shoulder and high left shoulder; and with the head tilted to the low shoulder and rotated toward the high side or to the left. Of course, one can take the various types of individuals from those who are the long, lank, and lean type to the short, obese type, and in these we have a change of body weight in its antero-posterior equi librium. It is this type with its complications of the scoliotlc type as well as those who produce a torsional or twisting curvature that are the most severe types to take care of in our office and get results. It is here that I must bring forth a word of warning. We must remember in tak ing X-Rays of our postural patients that we have approximately 35% to 50% error in the standing position in the AP as well as on the laterals. When we analyze these particular films, we must consider that the only help that these X-rays can give us is in showing to us the amount of shortness in the leg and the amount of change in normal angle of the lumbosacral articulation, also the amount of bone pathology. We cannot, 221 from our X-rays, determine the amount of lateral deflection, the amount of torsional deflection, or the amount of antero-pos-. terior deflection. Therefore, our analysis has to be made up from some other source or instrument to be able to determine what procedure we should follow to take care of our postural patient. Another consideration that has to be taken into account is the shoe problem, for when we take X-rays of the patient's feet, they are taken in stocking or bare feet; and shoes, with their differences of construction, heel heights, and materials, alter the position of weight thrust. Therefore, may I again say to you that your analysis of the entire problem is only as good ALTERED ANTERO POSTERIOR EQUILIBRIUM GRAVITY LOAD DEFLECTED ANTERIORALLY Figure 4 as your visualization of the information the patient has given you and what you have found; and the correlation between the patient's symptoms and complaints and your findings.

Only those who use other competitive therapies have to worry about what the other fellow is doing.
