Ununited fracture of the hook of the hamate.

Of nine ununited fractures of the hook of the hamate, eight were treated by surgical excision of the fragment. All eight patients had relief from persistent pain and regained the preinjury level of function. This fracture occurs frequently in athletes and is often not diagnosed because it can be demonstrated only by special roentgenographic views. It is concluded that this fracture may be less rare than is commonly believed and that surgical excision permits early return of function, especially in athletes and laborers who must be able to grip hard objects strongly.
