Revision of a failed Swanson arthroplasty to a total wrist replacement restores wrist function and movements

摘要

This study reports a case of revision of a failed Swanson silastic interpositional wrist replacement to a Universal 2 (KMI medical Inc, San Deigo, CA, Jan 2009) total wrist arthroplasty, in a 68-year-old woman with rheumatoid arthritis and pyrophosphate arthropathy. At the 2-year follow-up, the patient was pain-free and was able to performall activities of daily living, documented by subjective assessment and objective scores. The disabilities of the arm, shoulder, and hand (DASH) scores improved from 98.3 preoperatively to 55.1 postoperatively. A failed Swanson silastic interpositional wrist replacement may be successfully revised to an uncemented primary wrist replacement with good functional results at early follow-up.
