The hamate bone (unciform bone) is a bone in the human wrist readily distinguishable by its wedge shape and a hook-like process projecting from its palmar surface.
It is situated at the medial and lower angle of the carpus, with its base downward, resting on the fourth and fifth metacarpal bones, and its apex directed upward and lateralward. The bone is also found in many other mammals, and is homologous with the "fourth distal carpal" of reptiles and amphibians.
The etymology derives from the Latin hamatus "hooked," from hamus which means "hook."

The hamate bone has six surfaces:
- The superior, the apex of the wedge, is narrow, convex, smooth, and articulates with the lunate.
- The inferior articulates with the fourth and fifth metacarpal bones, by concave facets which are separated by a ridge.
- The dorsal is triangular and rough for ligamentous attachment.
- The palmar presents, at its lower and ulnar side, a curved, hook-like process, the hamulus, directed forward and lateralward.
- The medial articulates with the triangular bone by an oblong facet, cut obliquely from above, downward and medialward.
- The lateral articulates with the capitate by its upper and posterior part, the remaining portion being rough, for the attachment of ligaments.
Clinical significance[edit]
The hamate bone is the bone most commonly fractured when an amateur golfer hits the ground hard with a golf club on the downswing. The fracture is usually a hairline fracture, commonly missed on normal X-Rays. Symptoms are pain aggravated by gripping, tenderness over the hamate and symptoms of irritation of the ulnar nerve. This is characterized by numbness and weakness of the pinky finger with partial involvement of the ring finger as well, the "ulnar 1½ fingers."
It is also a common injury in baseball players. Several professional baseball players have had the bone removed during the course of their careers.[1][2][3][4][5] This condition has been called "Wilson's Wrist".[6]
The calcification of the unciform bone is seen on X-rays during puberty and is sometimes used in orthodontics to determine if an adolescent patient is suitable for orthognathic intervention (i.e. before or at their growth spurt).
