Hamate
Hamate
Hamate (pronunciation: /ˈhæmeɪt/), also known as the unciform bone in older texts, is one of the eight small bones that form the carpus or the wrist in the human body.
Etymology
The term 'hamate' is derived from the Latin word 'hamatus', which means 'hooked'. This is in reference to the bone's unique hook-like shape.
Anatomy
The hamate bone is situated on the ulnar side of the carpus, distal to the lunate and triquetral, proximal to the fifth metacarpal and fourth metacarpal, and lateral to the capitate. It is characterized by its wedge shape and the distinctive hook, also known as the hamulus, which projects from its palmar surface.
Clinical Significance
Injuries to the hamate, such as fractures or dislocations, are relatively rare but can have significant implications. The most common injury is a hook of hamate fracture, often resulting from sports activities. Diagnosis can be challenging due to the bone's deep location and the often subtle symptoms. Treatment typically involves immobilization, but surgery may be required in some cases.
