19. Describe the 3 degrees of injury and explain the signs and symptoms of each.
a. First Degree
1. Results when the tissues have been overly stretched
2. This commonly results in “micro-tears” in the tissue that may
not be apparent at a macroscopic level
3. Symptoms include:
i. Pain
ii. Minor swelling
iii. Loss of function that may or may not limit activity
iv. Integrity of the fibers is generally maintained
b. Second Degree
1. Results when the tissue is partially torn
i. Moderate pain
ii. Moderate Swelling
iii. Loss of function that usually limits activity
iv. may result is some ecchymosis
v. Integrity of the fibers is affected with joint laxity or decreased
strength
c. Third Degree
1. A complete rupture of the tissue
i. Sever Pain
ii. Moderate to sever swelling
iii. Probable ecchymosis
iv. Complete loss of integrity of the joint or complete loss of
function
20. Name the stages of healing using both of the common names for each, explain
generally what occurs in each, and the time frame of each.
Acute (Inflammation)Phase
48-72 hours
Signs of inflammation are appernent and cells debris is being
cleaned us
Subacute (Repair and regeneration) Phase
3-4 Weeks
Normal blood flow is regained and the regeneration of damaged
tissue with collagen is begun
Remodeling (Maturation) Phase
Up to 1 year
Collagen fibers are strengthened
