Abstract

Congenital distal tibio-fibular synostosis is a very rare disease with no reported cases in Korea. An 8 year old girl complained of ankle discomfort and deformity due to distal tibio-fibular synostosis. The patient was treated with an autogenous fat graft after a bone bridge resection and fibular osteotomy to restore the ankle mortise. Osteosynthesis with a plate was performed to treat the fibular nonunion during the follow-up. Fibular union was achieved, and there have not been any subjective symptoms or limitations of outdoor activity and ROM during a four and half year follow up.
