Volar radial Carpometacarpal dislocation of the fourth and fifth fingers

Abstract

Carpometacarpal ligaments converge at the base of the metacarpal. Only very violent trauma can cause carpometacarpal dislocation. We report the case of a 23-year-old patient admitted for volar dislocation of the 4th and 5th finger with radial displacement. We did proceed to a closed reduction maintained by a splint the evolution was satisfactory with the recuperation of grip force. The mechanism of the injury can be direct or indirect. The displacement can suggest is there or not a complete rupture of the carpometacarpal ligaments. After closed reduction, the treatment can be surgical (which is preferred) with k-wire fixation or nonsurgical with splint immobilization with a close follow-up to avoid the loss of the reduction.
