Wrist joint prosthesis used for treating severe arthritis

摘要

The prosthesis has an articulation (1) to be anchored at the proximal end of the large bone (7) and a section (2,3) to be anchored in the distal end (8) of the radius (9) after partial resection. The proximal articulation has a partially spherical cap (4) with a shaft (6) to fit into the large bone to retain the cap.
