This paper reports a rare case of fracture-dislocation of the hamatometacarpal joint. A 25-year-old right-handed man was involved in a fistfight and struck a wall with his left fist. He was examined at our hospital 5 days after injury and found to have swelling and tenderness in the vicinity of the fourth and fifth CM joints. Radiographs of the hand revealed dorsal dislocations of the bases of the fourth and fifth metacarpal accompanied by a dorsal oblique intra-articular fracture of the distal hamate and an avulsion fracture of the base of the fourth metacarpal. Treatment consisted of closed reduction and percutaneous fixation with Kirschner wires. Three years after his injury, the patient is asymptomatic, working at his previous job, with a full ROM of all joints of his left hand wrist and normal grip strength.
