简介：双边的肩膀脱臼arerare并且几乎总是发生在以后的方向。同时的双边的前面的肩膀脱臼甚至更稀罕，仅仅一些案例在文学被说。当同步、同时的力量被需要导致它，双边的肩膀脱臼的最有趣的部分关于它的损害机制。在癫痫或电刑的情况下，机制是不同的，肌肉的选择的组的有力的收缩导致脱臼。这篇文章报导在一个癫痫的病人发生在一个道路方面事故以后并且在骚动的一个事件以后的双边的同时的前面的肩膀关节脱臼的二个案例。脱臼早被诊断并且与合适的postreduction康复立即减少了。在他们的后续期间，bothpatients有令人满意的功能的结果。这篇文章在道路方面事故牺牲品和癫痫的病人在肩膀检查的重要性上强调。所有矫形surgeonsand紧急情况医生应该知道如此的不平常的可能性有早诊断和治疗。早减小和适当康复能提供令人满意的功能的结果。这篇文章简短也讨论损害机制，诊断并且在文学报导了的双边的肩膀脱臼的治疗。
