[Treatment of rupture of the peripheral radio-ulnar joint with chronic dislocation or subluxation].

Some possible treatment methods in luxations and subluxations of the distal radio-ulnar joint are discussed, especially in case of posttraumatically restricted pronation and supination of the forearm. An own method to treat these injuries is proposed which has been developed on the basis of former techniques. This method has proved very successful in two patients with extremely poor mobility values of the wrist joint in whom no measurable reduction of rough strength was observed. The further development of this method consists in a bone insertion between the peripheral ends of ulna and radius corresponding to the natural distance between both bones. Another new development is the resection of about 3 to 4 cm within the central third of the ulna.
