[Kessler arthroplasty of the carpometacarpal joint of the thumb in arthrosis and arthritis].

Early results of the KESSLER-Implant in 11 patients are presented. 7 patients suffered from rheumatoid arthritis, 1 from psoriatic arthropathy. For technical reasons this endoprosthesis seems to be especially suitable for patients with rheumatoid disease. By remodelling the articular surface of the trapezium corresponding to the implant, it is possible to reestablish stability even in cases with severe destruction and subluxation of the CM joint.
