Purpose: Different surgical procedures have been proposed for treatment of Distal Radioulnar Joint (DRUJ) arthrosis and other conditions. In this study, we aimed to introduce a new design of DRUJ prosthesis base on Suave Kapadji Procedure and evaluate its short-term results. Darrach and Suave Kapadji techniques are two well-known salvage procedures. To avoid the disadvantages of these procedures, various implant designs have been proposed for DRUJ substitution.
Methods: Before and after insertion of the intraosseous DRUJ prosthesis in five patients, indexes such as range of motion, grip and pinch strengths were measured and recorded and three questionnaires (Quick DASH, VAS-Pain, and PRWE) were filled out.
Results: The patients were followed up for 27.6 months. All patients completed the follow-up period with no complication except one who came with dislocation secondary to forearm malunion and proximal forearm impingement. In comparison with before operation, all indexes improved.
Conclusion: The intraosseous distal radioulnar prosthesis can be an alternative option for replacement of DRUJ.
