Dorsal dislocation of the distal end of the ulna in a judo player.

A 32-year-old policeman injured his left wrist while engaged in judo training. A distal radio-ulnar dislocation, ulna dorsal, was reduced under general anesthesia, but, as the distal radio-ulnar joint was unstable, a Liebolt's ligamentous reconstruction procedure and a partial excision of the triangular fibrocartilage complex were carried out. The patient could resume his job eight weeks after the operation, and light training after a further six months. The need for proper physical examination and accurate radiographic positioning is stressed.
