Chronic Ulnohumeral Subluxation After Surgical Treatment of Lateral Condylar Fracture Dislocation of the Elbow in a Child: A Case Report.

CASE: A 10-year-old boy presented with chronic ulnohumeral subluxation 6 months after an open reduction of a Milch type II lateral condyle fracture subluxation performed at another hospital. The patient had persistent elbow pain and limited range of motion (ROM) between 20° and 50°. After the open reduction for chronic ulnohumeral subluxation and corrective osteotomy for articular surface reconstruction, he had an uneventful recovery with improved ROM of the affected elbow and no pain. CONCLUSIONS: Intra-articular corrective osteotomy for articular surface reconstruction may be feasible to improve mobility and relieve pain in pediatric patients with lateral condylar malunion and elbow subluxation.
