Basics

Description

  • Dislocation of the lunate relative to the radius and distal row of metacarpals, most are volar but can be dorsal.
  • Usually from high-energy hyperextension with ulnar deviation of the wrist.

Etiology

  • Implies disruption of all 4 perilunate ligaments and radiocarpal ligament (Mayfield classification, stage IV)
  • In volar dislocations, median nerve injury occurs in the carpal tunnel.
  • Associated fractures of the radial styloid, scaphoid, capitate, and triquetrum are common and, if present, should raise suspicion of an occult perilunate ligamentous injury.
