Hook of hamate fractures often result from athletic activity involving the use of golf clubs, baseball bats, tennis rackets, etc. Most hook of hamate fractures heal if well immobilized immediately.
A hamate fracture can be diagnosed with a physical exam and x-rays. The most common symptom is pain in the palm aggravated by grasp. Other symptoms of a hamate fracture include diminished grip strength, dorsal wrist pain, and ulnar nerve paresthesia.
A CT scan is the best way to identify the hook of hamate fracture.
Hamate fractures that are well immobilized immediately and are treated soon after injury have excellent outcomes. A fracture which does not heal will require excision of the hook of the hamate. Patients with excisions of hook of hamate usually return to their pre-injury level of activity.
