Simultaneous dislocation of the five carpometacarpal joints.

Two new cases are added to the literature on four previously reported cases of simultaneous dislocation of the five carpometacarpal joints. The priorities of management of other more extensive injuries often delays definitive treatment and in the two cases reported here open reduction and internal fixation was necessary to restore the functional structure of the hand. Restoration of normal grip and pinch strength was obtained in both patients with stable, pain-free carpometacarpal joints.
