Abstract
Nonoperative treatment for talar neck fracture may cause loss of reduction and malunion or nonunion even when using a cast. We treated a 16-year-old female who had painful malunion after nonoperative treatment for talar neck fracture. We concluded that the cause of the ankle pain must be an impingement of the medial side of the talus and medial malleolus in preoperative assessment. We treated the malunion with correctional osteotomy along the former fracture plane. The time interval between injury and operation was 14 weeks. Postoperative radiographs showed no signs of avascular necrosis and arthrosis. We evaluated the patient's ankle function by JSSF (Japanese Society for Surgery of the Foot) scale. The score improved from 32 points, preoperatively, to 100 points, postoperatively.
