Lateral Malleolus Reconstruction After Tumor Resection in Children: A Case Report and Literature Review

BACKGROUND: Pediatric reconstruction of lateral malleolus was necessary and challengeable. Up to now, vascularized fibular was the optimal graft to reconstruct epiphyseal defection. However, the sophisticated microvascular operation has limited the wide application of this technique. CASE PRESENTATION: We present the case of a 9‐year‐old boy with Ewing sarcoma in left distal fibula. In order to restore the growth capacity, we used reverse‐flow vascularized fibular epiphyseal graft with tibialis anterior artery to reconstruct the bone defect after tumor resection with no microvascular anastomosis. More than 4 years after the operation and adjuvant chemotherapy, the patient was free of pain and recurrence, and the function and stability of ankle joint was perfect. Radiology examination revealed satisfied bony union of fibula and normal growth of the fibular head transplant. CONCLUSIONS: The advantage of reverse‐flow vascularized fibular epiphyseal graft is requiring no microvascular anastomosis which could not only shorten operating time, but also reduce factitious damage of vessels. This report presented that this technique might be an available option for reconstruction of lateral malleolus in children.
