Hook of Hamate Fracture
The hamate is a wedge shaped carpal (wrist bone) located on the medial (little finger) side of the wrist. The hamate has a hook-like bony protuberance which projects from the palmar aspect and is one of the bones that forms the tunnel of Guyon. A fracture of the hook of hamate typically follows direct trauma from a fall or direct blow and typically presents as pain over the medial (inside) aspect of the wrist and hand. Complications associated with hook of hamate fractures include ulnar nerve compression or Guyon’s Canal Syndrome.
