TERMINOLOGY
Definitions
- Boutonnière deformity: extensor tendon central slip injury at or near insertion on middle phalanx; results in PIP joint flexion + DIP extension
- Coach's finger: PIP dislocation, typically dorsal; ± volar plate injury
- Jersey (rugby) finger: flexor digitorum profundus (FDP) tendon avulsion ± avulsion fracture
- Most commonly affects ring finger
- Gamekeeper's (skier's) thumb: injury to ulnar collateral ligament (UCL) of 1st MCP joint
- Related to hyperabduction
- ± avulsion fracture
- Mallet (baseball, drop) finger: forced flexion of extended DIP joint with injury to terminal extensor tendon ± avulsion fracture
