Abstract

Fracture-Dislocation of the the body of the hamate is rare in carpal bone fractures. Recently, we experienced two patients with coronal fracture of the dorsal aspect of the hamate with dorsal subluxation of metacarpal bases of the ring and little fingers. The mechanism of injury was by indirect blow with c1enched fist in two patients. Two patients were treated with closed reduction and plaster immobilization for 6 weeks and physical theraphy. At 13 and 14 weeks follow-up respectively, two patients had no funtional limitation, no complaints referable to hand, and nearly solid union on radiographs. We report two cases of fracture of the the body of the hamate bone, associated with dorsal subluxation of hamatometacarpal joint treated by conservative methods and review of literatures.
