Ulna Autograft for Wrist Arthrodesis: A Novel Approach in Failed Wrist Arthoplasty
Rheumatoid arthritis is a polyarthropathy affecting approximately 1% of the population worldwide. Wrist involvement is observed around 75% of patients, resulting in substantial disability and morbidity. A multidisciplinary approach to management of such patients is undertaken to prevent disease progression, many go on to develop debilitating disease requiring surgical intervention. Total wrist arthroplasty and arthrodesis are the main options available for those with end-stage disease, with arthroplasty preferred due to its ability to preserve a good degree of wrist function. Where complications occur with total wrist arthroplasty, salvage surgery with arthrodesis can be considered, however this requires satisfactory bone stock to enable stable fusion of the joint following arthroplasty. We report our experience of Ulna strut allografts in wrist arthrodesis in the management of failed total wrist arthroplasty.
