The pisiform bone (/ˈpaɪsɨfɔrm/ or /ˈpɪzɨfɔrm/), also called pisiforme bone (Latin), is a small knobbly, pea-shaped sesamoid bone that is found in the wrist. It forms the ulnar border of the carpal tunnel.

Structure

The pisiform bone is a small sesamoid bone found in the proximal row of the carpus. It is contained within the flexor carpi ulnaris tendon.^[1]^:199,205

The pisiform bone may be known by its small size, and by its presenting a single articular facet. It is situated on a plane anterior to the other carpal bones and is spheroidal in form. It articulates only with the triquetral. It situated where the ulna joins the carpus (wrist).

Surfaces

Its dorsal surface presents a smooth, oval facet, for articulation with the triquetral: this facet approaches the superior, but not the inferior border of the bone.

The palmar surface is rounded and rough, and gives attachment to the transverse carpal ligament, and to the Flexor carpi ulnaris and Abductor digiti quinti.

The lateral and medial surfaces are also rough, the former being concave, the latter usually convex.

Function

Unlike the other carpal bones, the pisiform is not involved in movement of the wrist.^[2] ^:5

History

The etymology derives from the Latin pīsum which means "pea".
