Abstract
Developmental lateral femoral condyle hypoplasia is a rare cause of severe genu valgum and presents a challenge in achieving accurate correction while preserving osteotomy stability. We describe the management of a symptomatic adolescent using a lateral distal femoral opening-wedge osteotomy planned with the reversed Miniaci method. Developmental lateral femoral condyle hypoplasia is a rare cause of severe genu valgum and presents a challenge in achieving accurate correction while preserving osteotomy stability. We describe the management of a symptomatic adolescent using a lateral distal femoral opening-wedge osteotomy planned with the reversed Miniaci method. Pre-operative planning was performed using the reversed Miniaci method on long-leg standing radiographs to determine the correction angle and osteotomy parameters. A lateral distal femoral opening-wedge osteotomy was performed using Steinmann pins as hinge-protection guides. The osteotomy was gradually opened under fluoroscopic control until the planned correction was achieved. Alignment and preservation of the medial cortical hinge were confirmed fluoroscopically. The mechanical axis was restored to near-neutral alignment, and the correction was maintained throughout the follow-up period. Radiographic union was achieved with correction of gait pattern, improved cosmetic appearance, resolution of symptoms, and an American Knee Society Score exceeding 85 points, indicating excellent functional recovery. The reversed Miniaci method allowed individualized correction planning, while medial hinge protection and stable fixation were associated with maintenance of alignment, union, and satisfactory functional recovery at follow-up.
