| 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. |
