| Question | Answer |
|---|---|
| Colles' fracture | transverse fracture of distal radius with an POSTERIOR displacement of the distal fragment, caused by FOOSH, common for elderly |
| Smith's fracture | (reverse Colles') transverse fracture of distal radius with an ANTERIOR displacement of the distal fragment, caused by fall on back of hand |
| greenstick fracture | incomplete fracture, similar to partial breaking of a young tree limb |
| ganglion cyst | benign tumor mass (usually seen as a bump on the dorsal surface of the wrist) |
| carpal tunnel syndrome | numbness and tingling of the hand caused by compression of the median nerve |
| De Quervain's disease | pain on radial side of wrist caused by inflammation and thickening of sheath containing the extensor pollicis brevis & abductor pollicis longus |
| Dupuytren's contracture | palmar aponereurosis undergoes a nodular thickening |
| stenosing tenosynovitis | aka: trigger finger, a nodule or swelling of a tendon or sheath lining develops and prevents the tendon from sliding back to extension after finger flexion |
| skier's thumb | acute tear of ulnar collateral ligament of thumb |
| gamekeeper's thumb | stretching injury of ulnar collateral ligament |
| swan neck deformity | flexion of MCP joint, hyperextension of PIP joint, flexion of DIP joint |
| boutonnieren deformity | extension of MCP joint, flexion of PIP joint, extension of DIP joint |
| ulnar drift | ulnar deviation of fingers at MCP joints |
| mallet finger | distal phalanx remains flexed due to disruption of extensor mechanism (either from severed tendon or avulsion) |
| scaphoid fracture | most frequently injured carpal bone (usually due to a FOOSH of a younger person){high incidence of avascular necrosis} |
| Kienbock's disease | necrosis of lunate developed after trauma |
