PURPOSE: To describe outcomes after surgical management of pediatric elbow dislocation with incarceration of the medial epicondyle.
METHODS: We conducted a retrospective case review of 11 consecutive children and adolescents with an incarcerated medial epicondyle fracture after elbow dislocation. All patients underwent open reduction internal fixation using a similar technique. We characterized outcomes at final follow-up.
RESULTS: Average follow-up was 14 months (range, 4-56 mo). All patients had clinical and radiographic signs of healing at final follow-up. There was no radiographic evidence of loss of reduction at intervals or at final follow-up. There were no cases of residual deformity or valgus instability. Average final arc of elbow motion was 4° to 140°. All patients had forearm rotation from 90° supination to 90° pronation. Average Mayo elbow score was 99.5. Four of 11 patients had ulnar nerve symptoms postoperatively and 1 required a second operation for ulnar nerve symptoms. In addition, 1 required a second operation for flexion contracture release with excision of heterotopic ossification. Three patients had ulnar nerve symptoms at final follow-up. Two of these had mild paresthesia only and 1 had both mild paresthesia and weakness.
CONCLUSIONS: Our results suggest that open reduction internal fixation of incarcerated medial epicondyle fractures after elbow dislocation leads to satisfactory motion and function; however, the injury carries a high risk for complications, particularly ulnar neuropathy.
TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
