Simultaneous bilateral fractures of the femoral neck are rare injuries,which are reportedly induced by low-speed energy with predisposing factors including systemic diseases,medications and eclamptic seizures.Those caused by high energy are even rarer.High energy-induced bilateral fractures of the femoral neck conceive of high incidence of mortality and present great challenges in the early management.We report one case of a 52-year-old man with simultaneous bilateral fractures of the femoral neck which resulted from a motor pedestrian accident.One-stage closed reduction and intal fixation was done following the emergent resuscitation and neurosurgical management for concomitant brain injuries.The fractures united.There was no pain in the hips,and they had a normal range of motion.The treatment protocol,mechanism of the injury and possible postoperative complications were discussed to expand a comprehensive understanding about these infrequent types of fractures.
