Carpometacarpal joint

Bones of a human wrist. In this photo both the free position and saddle shape of the first CMC joint and the proximal transverse palmar arch are clearly visible.

The carpometacarpal (CMC) joints are five joints in the wrist that articulate the distal row of carpal bones and the proximal bases of the five metacarpal bones.

The CMC of the thumb or the first CMC, also known as the trapeziometacarpal joint (TMC), differs significantly from the other four CMCs and is therefore described separately.
