Salvage of a failed Sauve-Kapandji procedure using a total distal radio-ulnar joint replacement

This is the first report in the literature of a patient treated with a DRUJ replacement after Sauvé-Kapandji procedure failed due to pain and instability. The DRUJ replacement is an unconstrained, biomechanically more advantageous implant which can confer stability in cases where soft tissues are inadequate. We describe the treatment and outcome of persistent ulnar instability with a distal radio-ulnar joint replacement following failed salvage procedures for a malunion of a distal radius fracture.
