Dorsal dislocation of the trapezoid

Abstract

A case of dorsal dislocation of the trapezoid associated with dorsal subluxation of the carpometacarpal joints of the index and long fingers is described. The initial trapezoid subluxation was overlooked and it progressed quickly to a complete dislocation. Open reduction and capsular repair without internal fixation was followed by early recurrent trapezoid subluxation. Repeat open reduction combined with a limited intercarpal arthrodesis was used as a salvage procedure and produced a good result.
