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.
Wrist Fractures. A wrist fracture is a medical term for a broken wrist. The wrist is made up of eight small bones which connect with the two long forearm bones called the radius and ulna. Although a broken wrist can happen in any of these 10 bones, by far the most common bone to break is the radius. This is called a distal radius fracture by hand surgeons (Figure 1).
