 Abstract
- An 8-year-old girl presented after a traffic accident with a severe crush and degloving injury of the medial right ankle and foot, a distal tibiofibular fracture, and medial midfoot bone defects. After staged irrigation and debridement with temporary external fixation, definitive reconstruction was performed on August 6, 2016. The medial malleolar defect (2.5×2.0 cm) was reconstructed using a contoured autologous iliac crest bone graft secured with internal fixation, and medial stability was augmented using harvested gluteal fascia as a deltoid ligament substitute fixed with suture anchors. A bone-cement spacer was placed adjacent to the injured physis to mitigate physeal bridging, and the extensive soft-tissue defect was covered with a free anterolateral thigh flap and skin graft. During follow-up, progressive varus deformity and contracture were managed with corrective osteotomy and plating, Achilles tendon lengthening, Z-plasty, and Ilizarov fixation. At the final follow-up (March 6, 2025), the limb-length discrepancy was 5 mm, active ankle dorsiflexion was 0° (passive dorsiflexion 5°), and the patient was pain-free with full participation in daily activities, including hiking and dancing. This case emphasizes the value of an integrated staged strategy that combines bony reconstruction, medial stabilization, physeal management, and durable soft-tissue coverage during skeletal growth.
