Dorsal carpometacarpal ligaments

Dorsal carpometacarpal ligaments are a group of ligaments found in the hand. They are part of the complex network of ligaments that provide stability and flexibility to the hand and wrist.

Anatomy

The dorsal carpometacarpal ligaments are located on the back (dorsal) side of the hand. They connect the carpal bones to the metacarpal bones, hence their name. There are five dorsal carpometacarpal ligaments, one for each metacarpal bone.

Function

The primary function of the dorsal carpometacarpal ligaments is to stabilize the joints between the carpal and metacarpal bones. They prevent excessive movement in the wrong directions, while allowing the necessary flexibility for the complex movements of the hand.

Clinical significance

Injury to the dorsal carpometacarpal ligaments can result in instability of the hand and wrist, and can lead to conditions such as carpometacarpal joint syndrome. Treatment typically involves rest, immobilization, and physical therapy. In severe cases, surgery may be required to repair the damaged ligaments.
