[Is resection-interposition arthroplasty in chronic polyarthritis an alternative to alloarthroplastic replacement of the wrist joint?].

Rheumatoid arthritis involving the wrist joint frequently causes destruction and subsequent dislocation of the radio-carpal joint. The resultant loss of function requires a stabilisation procedure to correct it. In order to preserve function, various types of prosthesis for the wrist joint have been developed and their values are discussed. The resection interposition arthroplasty described here not only improves stability but also appearance and function. The operative procedure and results are presented.
