Osteoarthritis – Hand and Wrist-Total Wrist Arthroplasty: A Single-Center Study of 219 Cases With 5-Year Follow-up

Total Wrist Arthroplasty: A Single-Center Study of 219 Cases With 5-Year Follow-up

Pdf Summary

A study conducted in Sweden evaluated the survival rates and complications of total wrist arthroplasty (TWA) in 219 cases over a 5-year period. The study included 189 patients who received a TWA between 2002 and 2013. The primary end point of the study was revision for any reason. The study found that the cumulative implant survival after 8 years was 81% for the Biax implant, 94% for the Remotion implant, and 95% for the Maestro implant. Radiographic loosening was found in 26% of wrists with the Biax implant, 18% with the Remotion implant, and 2% with the Maestro implant. The study also assessed secondary outcomes such as range of motion, pain scores, grip strength, and patient satisfaction measures. The study found that pain scores and patient satisfaction measures improved significantly for all three implants. Grip strength improved for all implants, except the Universal 2 implant. Range of motion improved somewhat, particularly for the Biax and Maestro implants. Overall, the study found good midterm to long-term results for patients undergoing TWA, with a high level of patient satisfaction. The study suggested that radiographic loosening did not necessarily correlate with implant survival rates, but rather to the severity of wrist arthritis prior to surgery. The study concluded that all TWA implants studied offered a high level of patient satisfaction.
