Simultaneous dislocations of the bases of the four ulnar metacarpals upon the last row of carpals.

Abstract

Carpometacarpal dislocation of the base of one or more of the four ulnar metacarpals is extremely rare. This case report describes a carpometacarpal dislocation of all four ulnar metacarpals treated with open reduction under anaesthesia and internal skeletal fixation for six weeks. The result twelve weeks after the accident was functionally and anatomically excellent.
