Abstract
Astable distal radioulnar joint (DRUJ) is mandatory for the rotation and load transmission in the forearm and wrist. Salvage procedures such as the Darrach operation, Bowers arthroplasty, and the Kapandji-Sauvé procedure include the potential risk of dynamic radioulnar instability and impingement, despite stabilizing techniques addressing the soft tissues. In an attempt to stabilize the distal forearm mechanically following ulnar head resection, various endoprostheses have been developed to replace the ulnar head. These prostheses can be used for secondary treatment of persistent complaints and unsatisfactory results after ulnar head resection, but also in the primary treatment of osteoarthritis of the DRUJ. Based on promising results concerning improvement in pain, range of motion, and grip strength, with proper indications ulnar head prostheses should be considered as avaluable treatment option for osteoarthritis of the DRUJ.
