Two cases of traumatic anterior dislocation of the ulna at the inferior radio-ulnar joint were presented. Both cases were male. One visited us immediately after the injury and the other three weeks after the injury. This case had been treated in another hospital as fracture of the ulnar styloid process by a long arm cast. Paresis of the median and ulnar nerve was seen in both patients. The acute case could be reduced by manual reduction. In the other case manual reduction was failed and Darrach's operation was carried out four weeks after the injury. Five months after the operation he complained pain at his operated wrist when he carried a heavy thing with his hand. Roentgenograms showed a hollow depression on the ulnar border of the distal radius where face to the stump of the ulna.
