Ulnar procedures for post-traumatic disorders of the distal radioulnar joint

Post-traumatic abnormality of the distal radioulnar joint (DRUJ) still presents a therapeutic challenge to orthopaedic surgeons. The most common difficulty is a failure to diagnose these injuries early, resulting in chronic post-traumatic disorders of the DRUJ. The main aim of therapy is to avoid adverse sequelae. This is of particular importance in malunion of the distal radius, the most common cause for post-traumatic disorders of the DRUJ. Distal radial malunion can be avoided by early appropriate treatment and the need for subsequent ulnar procedures reduced. Ulnar procedures for post-traumatic disorders of the DRUJ are intended to improve function and to decrease pain. Many methods to improve post-traumatic DRUJ function have been described. This article reviews the current state of the art in dealing with post-traumatic disorders of the distal radioulnar joint and presents algorithms to help in decision making.
