1. Fractures of the lateral condyle in children are known as capitellar fractures, and, when they occur above the origin of the extensors, are accompanied by marked displacement of the lower fragment, causing it to turn over.
2. Closed reduction has given satisfactory results in those patients who sought advice soon after the accident. The main principles are reduction of the effusion, and then the manipulation of the lower fragment into position with the elbow in flexion and the forearm in pronation. If the forearm is supinated it is found that the gap between the fragments after reduction becomes greater.
3. In the cases which were not treated properly, malunion caused limitation of movements at the elbow. In two cases ulnar transposition improved the functional movement of the elbow; and in one case, with marked new bone formation, rest in flexion improved the functional movement.
4. A slight exaggeration of cubitus valgus deformity has been the rule even in cases with a good roentgenographic apposition and union of the fragments.
