Osteosarcoma over distal fibula is a rare disease. Wide resection of a malignant tumor of the distal fibula may lead to severe lateral ankle instability, lateral displacement of the talus, and even severe ankle osteoarthritis. We present a case of a 16-year-old girl presented with painful swelling over lateral ankle. Radiography revealed an expansile lesion and periosteal reaction over the distal fibula. Magnetic resonance imaging revealed a solitary heterogenous lesion. Histological examination of the open biopsy specimen revealed osteosarcoma. Wide resection and biological reconstruction with allograft followed by skin graft was performed. Over 12-year follow-up, radiography revealed good union. The lateral malleolus allograft appeared to support fair lateral stability over the ankle. The patient had good functional recovery after the long-term follow-up. Osteosarcoma over distal fibula can be treated with wide resection and allograft reconstruction with good functional recovery after long-term follow-up.
