Dorsal metacarpal ligament

The dorsal metacarpal ligament connects each metacarpal at its base. This ligament is officially known as the dorsal carpometacarpal ligament, derived from the Latin ligamenta carpometacarpalia dorsalia. The dorsal metacarpal ligament is the strongest carpometacarpal ligament, connecting carpal and metacarpal bones at their dorsal surfaces. Several types of metacarpal ligaments exist, including the interosseous metacarpal ligament and the deep transverse metacarpal ligaments. The dorsal metacarpal ligament is one of several dorsal deep ligaments located on the back of the hand. Dorsal deep ligaments are located underneath the dorsal superficial ligaments and serve the function of connecting ligaments and small bones. The dorsal metacarpal ligament is situated near the proximal end of the bones of the hand. Its primary function is to stabilize the metacarpal joints. Injury to the ligaments of the wrist and hand can cause disruption of the movement of the wrist and hand, further leading to painful conditions such as arthritis. The carpometacarpal joints are connected by six volar ligaments and six dorsal ligaments. The dorsal ligaments are much stronger than the volar ligaments.
