Comprehensive Fracture Care in Rural Setting Disclosures Rural Fracture Care THE FRACTURE SAFARI I do not receive any material benefit from any medical supply company for trauma equipment but… Chris Parfitt, MD, FRCS Instead of this (Montreal!) Romance of Rural Medicine • Driving I see this! (Albreda Mountain) Romance of Rural Medicine • Be careful out there • Good time to talk about fractures! 406_426 1 Comprehensive Fracture Care in Rural Setting Learning objectives • You did not come here to learn how to do this • (I am sorry!) Digital X-rays allow easy consult • If in doubt, always call your friendly local orthopaedic surgeon • Please don’t mention my name! Learning objectives • You came here to learn or review what to do with this patient Variety of Opinion • Orthopaedic surgeons are like farmers arguing over the best farming methods • THIS IS WHAT I DO ON MY FARM Regarding distal radial fractures PRE-TEST Which one is false? 1. Casting does not hold reduction 2. Locking plates can hold reduction 3. In elderly (60 plus), the outcome of these is equal whether treated with cast or plate. 4. These fractures can be treated by a rural family doctor 406_426 2 Comprehensive Fracture Care in Rural Setting How would you treat this # 1. 2. 3. 4. Refer for surgery Figure of 8 bandage Simple sling Airplane splint How would you immobilize this? 1. Thumb spica cast 2. Refer for surgery 3. Below elbow cast 4. Splint Watson’s test is: 1. 2. 3. 4. Clinical test for shoulder instability A clinical test for Achilles tendon tear A good way to test the scaphoid Sherlock Holmes’ partner’s test Comprehensive Fracture Care What is true of this FX • Monteggia fracture DL • Called fracture necessity • Can be treated by rural family physician • Named after famous British surgeon Treat the Fracture • Treat the Whole Patient • Decision to refer • Identify and prioritize other injuries ATLS • Or treat the patient at your own location • Always check neurovascular status of the fractured limb • Then • What is this injury? • PRIZE QUESTION 406_426 3 Comprehensive Fracture Care in Rural Setting Principles of Fracture Management Fracture Treatment Checklist SAFARI 1. Set (reduce) the Fracture • Start with a straight bone • Alignment never improves with followup SET the fracture ARREST (immobilize) FOLLOW-UP ACTIVATE REHABILITATE INVESTIGATE I What is acceptable angulation • Acceptable angulation is where you END UP • Most fractures wander a bit in casts • Patients have little tolerance for acceptable angulation 2. Arrest (immobilize) 1. Cast 2. splint 3. Internal fixation After immobilization • ELEVATION AND ICE • ELEVATION AND ICE • ANALGESIA 406_426 4 Comprehensive Fracture Care in Rural Setting 3. Follow-up of Fractures • In adults and adolescents TAX weekly for most • In small children TAX every 3 to 4 days (they heal fast) • Follow until healing prevents displacement 4. Activate the limb • Start activation of the limb on your first follow-up visit • Helps prevent CRP syndrome 5. Rehabilitate • Healing comes from within, therapist is motivator but has special techniques that can help • Always offer some physio • Be aware of third party issues 3. Followup fractures • Always check the Xray yourself or get a verbal report • Never rely on the written report Activation of the Limb • Start immediate ROM of restricted joints • Weekly TAX sessions a good opportunity to monitor limb condition and encourage ROM and strengthening 6. Investigate • 6. Determine the need for investigation of the cause of the fracture, i.e. osteoporosis, child abuse, balance disorders, etc. 406_426 5 Comprehensive Fracture Care in Rural Setting Paediatric fractures • Fractures In growing bones • From birth Paediatric Fractures Etiology • Accidental injuries Paediatric Fractures • Until the growth plates close Paediatric fractures NAI NAI or child abuse fractures Vs • No accidental injury (NAI) Children's Fractures NAI • Most commonly in ages less than 3 • Most specific fractures are • 1.

Paediatric fractures NAI • Corner fracture (diagrammatic) 406_426 6 Comprehensive Fracture Care in Rural Setting Paediatric fractures: NAI Paediatric fractures NAI Typical fractures • Typical fractures: 2. Rib fractures • Skull • Sternum • Scapula TAKE HOME MESSAGE NAI Have high index of suspicion for non accidental injuries Get social worker involved early Treat parents with dignity Paediatric fractures’ fractures’ classification • Salter Harris classification • Dr Salter from Toronto here • Dr Robert Harris also from Toronto Salter mnemonic • Salter Harris 1 • 5% Salter mnemonic Type 2 • 75% • S • A • Straight through • Away from growth plate 406_426 7 Comprehensive Fracture Care in Rural Setting Salter mnemonic Salter mnemonic • Salter Harris Type 3 • 10% • Salter Harris Type 4 • 10% • L • TE • Fracture below the physis • Through everything Salter mnemonic • • • • Type 5 Rare R Rammed (crushed) Premature physial closure • Distal radius fractures • Less common than lower limb • Angular deformity better tolerated in upper limb Premature physial closure PPC • Complication of growth plate injuries • Common in tibia and femur (even in grade 1 and 2 injuries) Premature physial closure • Reduction restores alignment, but does NOT change the incidence of premature physial closure • Journal Ped. Orthopaedics 2013 406_426 8 Comprehensive Fracture Care in Rural Setting TAKE HOME MESSAGE METACARPAL FRACTURES • Treat as any other fracture (SAFARI) • Always mention premature physial closure to parents • Follow-up for 6 months at least post fracture Metacarpal Fractures: Assessment Metacarpal Fractures X-rays • True AP • Swelling • Only really important observation is assessment of rotation of fingers Metacarpal Fractures: X-rays • True lateral • Oblique view increases apparent saggital deformity because the 5th metacarpal is a slightly curved bone Acceptable Angulation of Metacarpal Fractures • Up to 40 degrees metacarpal neck 5 • More proximal fracture creates more deformity, accept less deformity • Metacarpals 2 and 3 accept little, 5 to 10 degrees of deformity • Rotational deformity not acceptable 406_426 9 Comprehensive Fracture Care in Rural Setting Metacarpal # Reduction • Easy to straighten the bone with Marcaine block around fracture • Use Marcaine with epi and a long 25 needle Pedestal Cast • Holds wrist in GENTLE extension with moulding under metacarpal head • Effective to hold reduced and nondisplaced fractures Metacarpal Fractures: Rx • Frontal view of cast with pressure point under fractured metacarpal head Metacarpal # Immobilization • Ulnar gutter is traditional • Gives comfort to the patient and comfort to the doctor • Not good for anything else Metacarpal Fractures: Rx • Because the wrist wants to fall into relative flexion, there is always pressure on the metacarpal head Example metacarpal fracture • Lateral X-ray 406_426 10 Comprehensive Fracture Care in Rural Setting Example Case Metacarpal fracture Metacarpal Fractures: Followup • Reduced • Now just follow with weekly X-rays for 4 to 5 weeks and take the cast off and start range of motion of the MCP joint • Pedestal cast Reasons for Referral • Open injuries • Rotational deformity • Multiple unstable fractures • Patient demand Scaphoid Fractures: Dx • History: dorsiflexion injury • Snuffbox tenderness Scaphoid Fractures • Need to diagnosis before you can manage it Watson’s test • Very sensitive test for scaphoid fractures and scapholunate separations • Find the tuberosity of the scaphoid 406_426 11 Comprehensive Fracture Care in Rural Setting Watson’s test • Put your thumb on the tubersity as you hold the wrist Watson’s test • Ulnar deviate the wrist • This extends the scaphoid Watson’s test • Radial deviate the wrist • This flexes the scaphoid Scaphoid # Xrays • Wrist with scaphoid view • Negative X-ray • Immobilize and follow-up OUCH! Scaphoid # negative X-rays • Immobilize and TAX in about 2 weeks • If still sore and negative x-ray arrange a bone scan • CT and MRI have lower sensitivity rate Scaphoid # immobilization • The old 406_426 12 Comprehensive Fracture Care in Rural Setting Casting scaphoid fracture • The new (Schramm 2007) • The thumb can be left free at the MCP joint • Much more functional cast • Much happier patient Scaphoid Fractures: Rx • X-rays are not conclusive to prove healing • Once you are fairly sure it is healed, put in a splint and arrange a CT scan Scaphoid Surgery • However, most larger reviews and metanalyses show no benefit of surgery for undisplaced fractures of the scaphoid • Always some complications with surgery Scaphoid # follow-up • Review every 4 weeks • Expect 10 to 12 weeks for healing! Scaphoid Fractures: Surgery • Some subspecialty papers point to the advantage of fixing all scaphoid fractures • Same healing time, but less time in a cast and less time off work Scaphoid Fractures • Indications for referral • 1. Displaced fractures more than 1mm • 2. Proximal fractures • (60 to 70 % healing in a cast) • 3.
