While shoulder dislocations are a common injury, dislocation in the posterior direction is unusual and often missed clinically. A traumatic posterior shoulder dislocation can be caused by a direct blow to the anterior shoulder or if a posteriorly directed force is axially applied through the forward flexed arm. A posterior shoulder dislocation can occur after a violent muscle contraction induced by an electrical shock or grand mal seizure. Posterior shoulder dislocations are commonly associated with posterior glenoid rim fractures and anterior compression fractures of the humeral head. This diagnosis should not be missed if a complete physical and radiographic exam are properly performed.
虽然肩关节脱位是一种常见损伤，但后脱位并不常见，临床上常被漏诊。创伤性肩关节后脱位可由直接撞击前肩部引起，或当向后的力沿轴向作用于前屈的手臂时导致。电击或癫痫大发作引起的剧烈肌肉收缩后也可发生肩关节后脱位。肩关节后脱位常伴有肩胛盂后缘骨折和肱骨头前压缩骨折。如果进行全面的体格检查和影像学检查，就不应漏诊这一诊断。
