摘　　要：1病例资料 患者,女性,29岁。主因＂踝关节骨折术后3周,踝关节功能受限＂于2014年12月31日于北京积水潭医院门诊以＂踝关节骨折术后伴脱位（左）＂收入院。患者签署知情同意书。Ankle joint fracture is one of the most common types of fracture. There are many researches on the injury mechanism,treatment principles and surgical techniques. A type of injury which combines posterior dislocation of fibula,known as the Bosworth injury,is relatively rare. In 1947,Bosworth first described this type of injury as an unusual ankle fracture dislocation with fixed posterior fracture dislocation of the distal part of the fibula. In this type of fracture,the proximal fibular shaft fragment locks behind the tibialis posterior tubercle. This rare ankle fracture variant is often not recognized in initial radiographs and requires a computed tomographic（ CT） scan for verification. But there are already many reports,discussing the injury mechanism,treatment principles and surgical techniques. However,there are few reports of anterior dislocation of the fibula,caused by either injury or surgery. The mechanism of the injury is still not clear. This article reports a case of anterior dislocation of the fibula. We report a patient with left ankle open fracture（ Lauge-Hansen pronation-external rotation stage Ⅲ,Gustilo ⅢA）. Open reduction and internal fixation was done in the initial surgery,but ended up with poor reduction,resulting in fibula anterior dislocation,anterior dislocation of talus and tibia fibular dislocation. The fibula was dislocated anteriorly of the tibia,which rarely happened. The patient suffered severe ankle joint dysfunction. The second operation took out the original internal fixation,reduced the fracture,and reset the internal fixation. The function of ankle joint was improved obviously after operation. But because of the initial injury and the two operations,the soft tissue around the fracture was greatly damaged. 6 months after the second operation,and the fracture still not healed,so the bone graft was carried out in the third surgery. Two months after the third surgery,the function of the ankle was significantly better than before,but the fracture healing was poor,which need
