Ultimate goals of Fx Tx
- Alignment of bones (angular and rotational)
- Restoration of proper length
- Restoration of apposition of the bone ends
- Adequate immobilization
acceptable angular deformity in child reduction of fx
15-20 degrees that is close to a joint and in same plane of motion
Top Ten principles of setting fx
- comparison xrays
- xrays in two planes
- look for an injury in another bone
- correct a both angular and rotational misalignment
- take stress xrays
- Do not be satisfied with one dx (always look for another injury.
- Reduce the fx ASAP
- evaluate for joint instability and tendon function
- usefulness of extremity (not just xray)
- Irreducibility may signify soft tissue interposition
Fracture healing overlap stages
Inflammation
Repair
Remodeling
Volkman’s Ischemic Contracture
acute ischemia and necrosis of muscle fibers of the flexor group of muscles in the forearm. especially the FDP and FPL. the muscles become fibrotic and shortened
time… delayed union or delayed healing
fracture not healed after 16-20 weeks.
time… non-union fracture
not healed after 60 or absence of evidence of progression of callus formation over 3 mo
osteonecrosis
fracture that results in compromised blood supply to bone and ultimately results in bone death
bones at risk for osteonecrosis
talus
scaphoid
femoral head
compartment syndrome P’s
Pain!! Pallor paresthesias Paralysis Pressure Pulselessness Poikilothermia
Compartment Syndrome: direct measurement of pressure in mmHg
< or equal to 30 mmHg
Volkmann’s Ischemic Contracture is a result of
Untreated arterial injury
compartment syndrome secondary to swelling in a tight cast.
