A 34-year-old man presented 2 weeks after sustaining posterior fracture dislocation of both shoulders due to a fall from a bicycle while riding downhill. Posterior fracture dislocation of both shoulders is typically caused due to seizures or electrocution. In our patient, the injury was caused by trauma, which is exceedingly rare. Owing to the late presentation, management of such injuries usually entails joint replacement; however, due to his young age, both shoulders were treated with open reduction and internal fixation. Bilateral posterior shoulder fracture dislocation is rarely encountered in clinical practice.

双侧后肩骨折脱位的异常原因：一例报告

一名34岁的男子因下坡骑自行车摔倒而导致双肩后方骨折脱位2周后出现。双肩后部骨折脱位通常是由于癫痫发作或电击伤引起的。在我们的患者中，伤害是由外伤引起的，这种情况极为罕见。由于呈报较晚，要处理此类伤害通常需要进行关节置换。然而，由于他的年龄很小，双肩均接受了切开复位内固定治疗。双侧后肩骨折脱位在临床实践中很少见。
