Pisometacarpal Ligament

Last updated: Dec 9th, 2024

The pisometacarpal ligament is a palmar ligament and is a strong, fibrous band. It is one of two palmar ligaments along with the articular capsule that connects the pisiform bone in the wrist. It joins the pisiform to the base of the fifth metacarpal bone, which joins the little finger. This ligament is (along with other pisiform ligaments), in reality, extensions of the tendon of the flexor carpi ulnaris.
