Volz total wrist arthroplasty in rheumatoid arthritis: a preliminary report.

The results of 20 Volz design total wrist arthroplasties in 19 patients with stages III and IV rheumatoid arthritis are presented. Follow-up averaged 18 months. Using a 100-point evaluation form, there were 75% excellent or good results and 10% poor results. An effective extensor carpi radialis brevis tendon and the presence of volar and ulnar contractures were the most important factors influencing the results. This operation is recommended in patients with painful stage III or IV rheumatoid wrist disease, and in whom the extensor carpi radialis brevis is functioning where preservation of motion is desired.
