We present a case of a 13-year-old female with severe varus deformity and limb discrepancy resulting from epiphyseal fracture. The preoperative tibial articular surface angle was 64.1°, and the affected tibia was 14 mm shorter than the contralateral tibia. She underwent a medial open osteotomy and fibular osteotomy with gradual distraction correction using Ilizarov fixator. The deformity was corrected at 3 months, and the external fixator was removed when bony union was achieved 6 months postoperatively. At 9 months after surgery, the patient could play basketball without feeling pain. At the last follow-up, namely 36 months after the operation, the American Orthopaedic Foot and Ankle Society hindfoot-ankle score was improved from 58 to 90, the patient was pain free, and the radiological measurements were nearly normal. Ilizarov fixator gradual distraction correction for distal tibial severe varus deformity is a safe and cost-effective method that can yield excellent radiological and clinical outcomes.
我们报告了 1 例 13 岁女性患者，因骺板骨折导致严重内翻畸形和肢体差异。术前胫骨关节面角为 64.1°，患侧胫骨比对侧短 14mm。患者接受了内侧开放截骨和腓骨截骨，使用伊里扎洛夫固定器逐渐进行牵伸矫正。3 个月时矫正了畸形，术后 6 个月骨愈合时拆除了外固定器。术后 9 个月，患者可以打篮球而无疼痛。末次随访时（术后 36 个月），美国矫形足踝协会后足-踝关节评分从 58 分提高至 90 分，患者无疼痛，影像学测量结果接近正常。伊里扎洛夫固定器逐渐牵伸矫正胫骨远端严重内翻畸形是一种安全且具有成本效益的方法，可获得良好的影像学和临床结果。
