Abstract:
Dislocation of the metacapophalangeal joint of the finger is apparently rare except thumb. The mecchanism of injury seems to be direct injury that produces hyperextension of metacapophalangeal joints. In 1957, Kaplan advocated the triple incision, that is release of the volar fibrocartilaginous plate, the natatory ligament, and the superficial transverse metacapal ligament, expose the operation field through palmar approach. In 1975. Becton advocate direct dorsal longitudinal incision. The advantages of this approach as compared with the volar approach are 1. There is full exposure of the fibrocartilaginous volar plate, the main structure blocking reduction. 2. Digital nerves are not as apt to be damaged. 3. Accurate reduction and fixation of the osteochondral fracture of the metacarpal head is possible. We exprenced 6 cases of index metacarpophalangeal dislocation and treated with dorsal approach.
