Background:It is possible that some hamate hook fractures are not diagnosed or treated, thereby affecting the study of their natural history. Study of the prevalence of incidental hamate hook fractures, nonunions, and other abnormalities on computed tomography (CT) ordered for another reason could document a subset of undiagnosed and untreated hamate hook fractures which might change our under...

BACKGROUND Hamate hook fracture is a common fracture in golfers and others who play sports that involve rackets or sticks such as tennis or hockey. This patient had a previous hamate fracture in the opposing wrist along with potential features of hamate bipartite. CASE PRESENTATION A 19 year old male presented with a complaint of right wrist pain on the ulnar side of the wrist with no apparen...

Hook of the hamate fractures are uncommon. This fracture is usually seen in sports involving a club or a racquet (i.e., baseball or golf) and is caused by blunt trauma. Stress fractures of the hamate are exceedingly rare. Because of its subcutaneous position and associated soft tissue structures, hook of the hamate fractures can be difficult to diagnosis. When treated early, conservative (non-o...

BACKGROUND Baseball players are susceptible to a number of specific upper extremity injuries secondary to batting, pitching, or fielding. Fractures of the hook of hamate have been known to occur in batters. The purpose of this study is to present our experience with the surgical management of hook of hamate fractures and their short-term impact on the playing capability of competitive baseball ...

Fractures of the hamate were classified by Milch (1) into body fractures and hook fractures; fractures of the body of the hamate were subdivided into those occurring on the radial side and those occurring on the ulnar side of the hook. Bowen (2) presented a hamate fracture in the coronal plane and, therefore, added a third category – fractures to the body of the hamate. The two cases described ...

The hamate bone, one of the carpal (wrist) bones, has a large uncinate process protruding from the palm side. In sports such as golf and tennis, the hamate bone can break if is subjected to a high external force, such as from the handle of a racquet or club. At our hospital we take X-ray images of the hamate bone from two directions: an axial image through the carpal tunnel and an image at the ...

The boundaries of the space through which the ulnar neurovascular bundle crosses the wrist have been reinvestigated. Using gross dissections, transverse and sagittal sections, and histologic study, we determined that the roof of Guyon's canal, the "carpal ulnar neurovascular space," does not directly connect to the hamate bone, as is currently accepted. The roof of this space extends radially t...
