Wrist Arthrodesis for Failed Total Wrist Arthroplasty
چکیده انگلیسی

PurposeTreatment options for failed total wrist arthroplasty include implant revision, resection arthroplasty, and arthrodesis. Variable results associated with different techniques have been reported for arthrodesis and the procedure has substantial technical challenges, including restoration of wrist height, obtaining stable fixation, and achieving bony fusion. This study evaluates the radiographic results of a surgical technique for conversion of a failed arthroplasty to an arthrodesis.MethodsA retrospective chart and radiograph review was performed in 20 wrists in 18 patients in whom conversion to an arthrodesis was performed using a contoured cancellous femoral head structural allograft and a wrist arthrodesis plate. Supplemental demineralized bone matrix combined with corticocancellous allograft chips was also used in 15 wrists. Median age at arthrodesis was 61 years (range, 45–78 years), and median follow-up was 34 months (range, 4–71 months).ResultsNineteen of 20 wrists fused following the index procedure at a median of 4 months (range, 3–7 months). Proximal plate loosening occurred in 1 wrist but the joint still fused at 6 months; a successful osteotomy and revision of screw fixation was done 2 years later to correct the deformity and hardware irritation in this case. Complications were otherwise limited to 1 superficial infection that resolved with intravenous antibiotics.ConclusionsThis technique for conversion of a failed total wrist arthroplasty to a wrist arthrodesis is safe, effective, and versatile. Wrist deformity is corrected, wrist height can be restored, stable fixation is obtained, and a high rate of fusion is achieved despite filling large defects using structural cancellous allograft.Type of study/level of evidenceTherapeutic IV.
