Fracture With Dorsal Dislocation of the Trapezoid and Trapezium at the Scaphotrapeziotrapezoidal Joint

Scaphotrapeziotrapezoidal fracture-dislocations are extremely rare injuries, requiring early recognition and treatment. We present a case of a 54-year-old man with scaphotrapeziotrapezoidal fracture/dislocation following a motor vehicle accident, resulting in dorsal dislocation of the first and second carpal-metacarpal joints through the trapezium and trapezoid. The identification of the dislocation was delayed, and a month after the initial injury, fixation was attempted elsewhere but had redislocated at the first postoperative visit. Subsequent fixation was successful, using both radial and ulnar buried Kirschner wires. The clinical outcome was excellent with stable reduction maintained at 21 weeks postop.
