Stress fractures of the lateral malleolus of the ankle joint are rare. Almost all cases are treated conservatively, for example with a casting and/or protected weight-bearing. We report a case of stress fracture of the lateral malleolus of the ankle joint for which correction osteotomy was needed. The patient, a 41-year-old woman, complained of pain in her right ankle after she had starting jogging one month previously. X-ray and CT examinations revealed a distal fibula fracture. X-ray showed a sclerotic change valgus angulation deformity, which seemed to put the malleolus at risk of stress fracture.Therefore, we performed surgical correction.
