Ilizarov Gradual Distraction Correction for Distal Tibial Severe Varus Deformity Resulting from Epiphyseal Fracture: Case Report and Literature Review.

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.
