Question | Answer |
---|---|
Transverse fracture | runs at a right angle to the long axis of the bone |
Oblique fracture | usu. Runs at a 45 degree angle to the long axis of the bone |
Spiral fracture | encircles the shaft of the bone, longer than oblique |
Comminuted fracture | composed of 2+ fragments |
Avulsion fracture | small fragments torn from bony prominences |
Butterfly fracture | elongated triangular fragment of cortical bone |
Segmental fracture | a segment of the shaft is isolated from two other larger fragments |
Compression fracture | compaction of bone trabeculae |
depressed fracture | fragments of a fracture are driven inaward, as with a blow to the skull. |
Stress/fatigue fracture | response to repeated stress, not a true fx |
Torus/buckle fracture | one cortex remains intact while the opposite is impacted |
Displacement fracture | separation of bony fragments |
Subluxation fracture | partial dislocation of a bone from a joint. |
Colles’ fracture | transverse fx of the distal radius and ulna with posterior displacement of the distal portions. Usu. “FOOSH” |
Most common fx of the carpal bones: | navicular |
Boxer’s fracture | transverse fx of the neck of the 5th metacarpal |
Monteggia fracture | isolated fx of the shaft of the ulna with anterior dislocation of the radius at the elbow |
Pott’s fracture | fx of both malleoli with dislocation of the ankle joint |
Trimalleolar fracture | fx of both malleoli and posterior tibia |
Jones fracture | transverse fx at the base of the 5th metatarsal, usu. With inversion injury. |
