• Dislocation of the head of the radius without fracture of the ulna was observed in nine otherwise healthy children after various injuries and in three additional children with various neuromuscular disorders. The first four cases of the series were recognized early and reduced promptly; they now show excellent results.
In the later eight cases reduction was not done, but the patients were followed as long as possible after the diagnosis had been made. Although function of the forearm and hand has not been perfect in any of them, there has not been any complaint of pain or any disturbance of growth at the wrist or hand.
For diagnosis, roentgen examination is essential. If the patient is seen early and if there is no fracture of the ulna, the authors recommend reducing the dislocation immediately and immobilizing the joint for about three weeks. If the diagnosis is delayed a month or more, they believe it is better to leave the dislocation unreduced, since the final result is better than that achieved by delayed surgical reconstruction.
