The model consists of a plastic hand. The carpal bones, the bones and the ulna, as well as the carpal disc and intra-articular ligaments are visible. On the extensor side of the hand, there are two channels leading to the joint cavity: the radial dorsal side and the elbow opening. The carpal pelvis can be attached to the ulna and carpal ligaments on both the flexor side and the extensor side, and can be replaced or replaced as needed.
