AbstractAlloarthroplasty has largely replaced traditional procedures in arthrosis of hip and knee joints. In contrast the role of alloarthroplasty in comparison to traditional procedures in hand surgery has been uncertain. To evaluate this question every registered hand surgery department (n=307) in Germany received a questionnaire requesting information on number and type of implanted prostheses and traditional procedures concerning the wrist joint, distal radioulnar joint (DRUJ), first carpometacarpal joint (CMC), metacarpal phalangeal joint (MP), interphalangeal joint (PIP), and preferred characteristics of the prostheses. Of the 307 hand surgery departments, 150 (57% of the hospitals and 42% of the visiting surgeons) participated in the inquiry. Per year, only 98 wrist prostheses were implanted (distributed among five different models) but 1534 traditional procedures were performed. The Sauve-Kapandji procedure was the most popular for the DRUJ and was performed 264 times per year. In comparison 24 hemiarthroplasties were implanted at the DRUJ. Trapezectomy remains the standard procedure for arthrosis of the first CMC joint (n=1399). The future importance of alloarthroplasty of the CMC joint is doubted by the majority of participating hand surgeons (90.3%). In contrast the majority (85.3/71.8%) is convinced that alloarthroplasty will be of importance for the MCP and PIP joints, respectively. Currently, the number of implanted prostheses is close to the number of traditional procedures performed at the MP joint. Irrespective of the joint involved, cementless anchorage is preferred as is the surface replacement anatomical design. The results confirm that alloarthroplasty in hand surgery is of minor importance. Thus, the role of alloarthroplasty differs depending on the joint involved. Traditional procedures except for the MP joint continue to be of major importance in hand surgery.
