1. Intra-articular displacement of the internal epicondylar epiphysis may complicate elbow dislocations in children with injury to the ulnar nerve.
2. Postreduction roentgenograms of all elbow dislocations should be taken to rule out this complication.
3. Immediate surgical reduction is the best course, although closed reduction is possible if the medial joint space is widened during manipulation.
4. Anterior transplantation of the ulnar nerve is advisable whether the epicondyle is excised or reattached.
5. An excellent end result may be expected if the condition is treated promptly and correctly.
