Abstract
We reported a case of the large fibular defect caused by osteomyelitis of fibula of a 20 years old male. He was hospitalized with the fractures of tibia and fibula in another hospital because of traffic accident. He was treated by osteosynthesis of tibia and fibula but suffered the large defect of the distal fibula (8cm long) with the equinovarus deformity due to osteomyelitis. We lengthened the fibula and then corrected the equinovarus deformity but was difficult to reduct the anterior dislocation of talus because of the narrowness of the ankle joint. So it can be thought that correction of the deformitry should be considered first before lengthening the fibula.
