Reconstructing the Rheumatoid Wrist: A Utility Analysis Comparing Total Wrist Fusion and Total Wrist Arthroplasty from the Perspectives of Rheumatologists and Hand Surgeons

Abstract

Rheumatologists and hand surgeons have historically demonstrated strikingly divergent attitudes toward the benefits of surgical intervention, either total wrist fusion or total wrist arthroplasty, for the rheumatoid wrist. A utility analysis was conducted to compare a national random sample of hand surgeons and rheumatologists regarding their opinions about surgical management of severe rheumatoid wrist disease. A web-based trade-off utility survey was developed, and participants were presented with survey scenarios comparing well-controlled rheumatoid arthritis with operative and non-operative management. Utility values were calculated for each scenario, and a decision analytic model was constructed. Utility values for rheumatologists and hand surgeons did not differ significantly for any scenario. Total wrist arthroplasty was associated with the highest expected gain in quality-adjusted life-years for each subgroup. This decision analytic model demonstrates similar opinions between two subspecialties that have historically demonstrated divergent attitudes towards rheumatoid hand surgery.
