Hook of Hamate Fracture - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s education animated video describing Hook of Hamate fractures. The hamate is one of the many carpal bones of the hand and wrist. The hamate bone is a triangular bone located in the distal carpal row situated on the ulnar side of the hand. The hamate is composed of a body and a hook. The ulnar nerve passes through the Guyon’s canal between the hamate and pisiform bones. The ulnar nerve can become injured by a fracture of the body (rare) or by a fracture of the hook (common) which may cause neuropathy of the ulnar nerve within the Guyon's canal. Hamate fractures are classified as either a hook fracture (common) or as a body fracture (Rare). Missing the fracture can lead to persistent pain from nonunion. Hamate hook fractures are most often seen in racquet, bat or club sports such as hockey and golf. Fractures of the hamate bone are difficult to diagnose, and routine x-rays may not show the fracture. Hook fractures of the hamate are best seen by carpal tunnel x-ray views.
