The radiocarpal joint is a synovial joint thatâs also found in the wrist. The radius articulates with the first row of carpal bones, except for the pisiform. It has a fibrous joint capsule thatâs attached to that distal end of the radius and the ulna and to the carpal bones.
The distal radius is part of the radius, one of the two bones in the forearm. The distal radius is the name given to the end of the bone that helps form the wrist joint. The distal radius articulates with three of the eight carpal bones of the wrist. This proximal row of carpal bones includes the scaphoid (navicular), the lunate, and the triquetrum.
