PURPOSE: To evaluate the results of Biaxial (DePuy Orthopedics, Inc., Warsaw, IN) total wrist arthroplasty (TWA) with a long metacarpal stem. METHODS: A retrospective review of the results of 17 long-stem metacarpal components for the Biaxial TWA implanted between 1993 and 1997 is presented. RESULTS: After surgery pain and grip strength improved markedly. Overall motion improved but only radial deviation was significantly better. All of the patients were satisfied. At the most recent follow-up evaluation 4 cases showed evidence of radiographic lucency about the cement mantle, but with no gross loosening or settling. No failures at a greater than 6-year average (4-year minimum) follow-up period have been noted. Two cases of intraoperative third metacarpal fracture and one case of dorsal metacarpal component placement were encountered but did not affect the outcomes. CONCLUSIONS: To date the survivorship of the Biaxial TWA with the long stem is favorable compared with previous reports with the standard Biaxial distal component.
