Fracture of the hook of the hamate

Abstract

We removed the fracture fragment from fifty-nine patients who had an isolated fracture of the hook of the hamate. Preoperatively, all had complained of pain and tenderness on the ulnar side of the palm or on the dorsal ulnar aspect of the wrist. Most fractures were thought to have occurred while the patient was swinging a racquet, golf club, or baseball bat. Some fractures were caused by striking the palm on a solid object, by falling on the palm, or by a crush injury to the hand. Most of the fractures were diagnosed conclusively on a carpal tunnel roentgenogram or on a special oblique roentgenogram of the wrist supinated. We now believe that computed axial tomography is the best imaging technique for demonstrating this fracture. Except for two patients who had a crush injury, all of the patients returned to their regular occupational and athletic pursuits. There were no surgical complications.
