In the treatment of distal radial fractures, the involvement of the articular surface of the radius may in some case cause serious problems. Because the anatomic reduction of seriously damaged and displaced fragments of the articular surface can not be always reconstructed. As a result of that, in follow-up, the patient can have progressive degenerative changes all over the wrist joint including articular surfaces of the carpal bones which might have been undamaged after the original trauma. At this point, the treatment alternatives are the fusion of the joint and total replacement arthroplastie. Unfortunately, the current status of the total wrist replacement arthroplastie is not so successful as some other joints. Consequently, total wrist arthroplastie is a kind of option which surgeons usually try to avoid. Here a new conceptual approach to wrist replacement arthroplasties has been brought to the agenda which permits the surgeon the partial and/or hemipartial joint replacement. In case of necessity, this partial arthroplastie can be converted to total joint replacement, and can be used in tumors, traumatic degenerative and rheumatismal conditions of this joint.
