Hamate bone Wrist". 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). The etymology derives from the Latin "hamatus" "hooked," from "hamus" which means "hook". Hamate bone The hamate bone or unciform bone (from Latin "uncus", "hook") is a bone in the human wrist readily distinguishable by its wedge shape and a hook-like process ("hamulus") projecting from its palmar surface. The hamate is an irregularly shaped carpal bone found within the hand. The hamate is
Intercarpal joints the hamate, the other, the pisometacarpal ligament, joins the pisiform to the base of the fifth metacarpal bone. These ligaments are, in reality, prolongations of the tendon of the Flexor carpi ulnaris. These joints are also arthrodial joints connected by dorsal, volar, and interosseous ligaments. The dorsal ligaments are three in number, extend transversely from one bone to another on the dorsal surface, connecting the greater with the lesser multangular, the lesser multangular with the capitate, and the capitate with the hamate. The volar ligaments are also three and have a similar arrangement on the volar surface. The three interosseous
