Combined fractures of the body and hook of hamate: a form of ulnar axial injury of the wrist.

Fractures of the hamate are rare, and usually associated with athletes. We describe an unusual form of the injury involving fractures of the hook as well as an intra-articular medial facet. It is likely to be a result of high velocity ulnar component of the axial injury. Surgical treatment is advocated to achieve accurate reduction and apposition of the fifth carpometacarpal joint.
