Carpometacarpal ligaments

Carpometacarpal Ligaments are a group of ligaments that connect the carpal bones to the metacarpal bones in the human hand. They play a crucial role in the mobility and stability of the hand, allowing for a wide range of movements and providing structural support.

Anatomy

The carpometacarpal ligaments are divided into two main groups: the dorsal carpometacarpal ligaments and the palmar carpometacarpal ligaments. These ligaments are further subdivided based on the specific bones they connect.

Dorsal Carpometacarpal Ligaments

The dorsal carpometacarpal ligaments are located on the back of the hand. They connect the carpal bones to the metacarpal bones, providing stability and allowing for movements such as extension and abduction.

Palmar Carpometacarpal Ligaments

The palmar carpometacarpal ligaments are located on the palm side of the hand. They connect the carpal bones to the metacarpal bones, providing stability and allowing for movements such as flexion and adduction.

Function

The primary function of the carpometacarpal ligaments is to provide stability to the hand while allowing for a wide range of movements. They prevent excessive movement of the bones, protecting them from injury. In addition, they contribute to the overall strength and dexterity of the hand.

Clinical Significance

Injuries to the carpometacarpal ligaments can result in conditions such as carpometacarpal joint dislocation and carpometacarpal joint arthritis. Treatment for these conditions may involve physical therapy, medication, or in severe cases, surgery.
