Hamate fracture is a break of the hamate bone in the wrist. Symptoms include pain in the front of the wrist in line with the little finger. It is made worse by gripping an object. Complications may include injury to the ulnar nerve and clotting of the ulnar artery.
The cause is typically injury during racket sports, baseball, or golf or a fall onto the hand. Types include hook (most common) and body (proximal pole, medial tuberosity, sagittal oblique, and dorsal coronal). Diagnosis is typically by X-rays, but may require special views such as a carpal tunnel or supinated oblique view; or a CT scan.
Treatment when the bones of well aligned is generally orthopedic casting for 4 to 6 weeks; though there is a high risk of it not healing. Otherwise surgery is indicated. For hook fractures surgery generally involves removal of the hook. Hamate fractures represent about 2% to 5% of breaks of bones within the wrist.
