The hamate is an irregularly-shaped carpal bone. Together with the trapezium, trapezoid and capitate bones, it comprises the distal row of carpal bones.

The main anatomical feature of the hamate bone is the hamulus, a bony projection located at the distal portion of its palmar surface.

The main function of this bone is to connect the distal row of carpal bones with the fourth and fifth metacarpal bones. The hamate bone serves as the attachment point for a number of muscles and ligaments of the hand and forearm. In addition, it participates in the formation of the carpal tunnel and Guyon's canal.

This article will discuss the anatomy, structure and functions of the hamate bone.
