Total Wrist Arthroplasty.

Total wrist arthroplasty has undergone substantial evolution in indications, implant design, and expected functional outcomes over the past decade. Osteoarthritis has overtaken rheumatoid arthritis as the major underlying etiology for joint replacement. Patient expectations have also evolved with a trend toward motion-preserving procedures. Finally, implant design based on careful experimental research efforts has assisted in outcome optimization. This article reviews these points in greater depth and provides examples and some technical points for the interested hand surgeon to consider.
