Understanding the Carpometacarpal Joint: Function, Injuries, and Treatment

Carpometacarpal refers to the joint that connects the wrist bone (carpal bone) and the metacarpal bone in the hand. There are four carpometacarpal joints, one for each finger, and they allow for flexion, extension, rotation, and circumduction of the fingers.

The carpometacarpal joint is a hinge joint that allows for movement of the fingers in multiple directions. It is formed by the union of the carpal bone and the metacarpal bone, and is surrounded by ligaments and tendons that provide stability and support to the joint.

Damage to the carpometacarpal joint can cause pain, stiffness, and limited mobility in the hand. Treatment for carpometacarpal injuries may include rest, physical therapy, and medication, or in severe cases, surgery may be necessary.
