Divergent Carpometacarpal Fracture Dislocation-An Uncommon Injury Pattern

Abstract

Carpometacarpal fracture dislocation of the hand is a relatively uncommon injury pattern. This injury is difficult to diagnose clinically, because of gross hand swelling which may obscure the characteristic deformity. The diagnosis of this unusual injury pattern also requires lateral radiograph of the hand which is essential for making precise diagnosis in suspected cases. We are presenting a case of divergent carpometacarpal joint fracture dislocation of index, middle and ring fingers with associated fracture of base of proximal phalanx of thumb and base of thumb metacarpal bone. Closed reduction supplemented with Kirschner wire fixation restored normal carpometacarpal joint anatomical alignment and achieved excellent clinical result.
