title: Fracture-dislocation of the ankle with anterior dislocation of the fibula.
abstract: A fracture-dislocation of the ankle with fixed anterior displacement of the proximal fibular fragment is reported. The mechanism of this injury was likely eversion of the foot which produced rupture of the deltoid ligament and distal tibiofibular diastasis, and lateral dislocation of the talus. The proximal fibular fragment was probably displaced laterally and returned to a position anterior to the fibular notch of the tibia. This injury was extremely unstable and required open reduction with internal fixation, not only to reduce the anterior displacement of the fibula but also to repair the associated disruption of the syndesmotic ligament and anterior capsule. The key radiographic finding was anterior displacement of the distal fibula seen on the lateral view.
