目的：探讨肩关节后脱位的检查方法及X线表现，提高诊断正确率。方法本组12例患者，11例摄有患肩正斜位片，4例健侧对比，明确肩关节后脱位，再经CT检查证实；1例只有患肩正位片，经多体位透视诊为肩关节后脱位，加照腋位片时复位。并对本组病例的检查方法、体位及X线表现进行了认真观察分析。结果本组12例肩关节后脱位患者，正位片均有异常表现；11例斜位片均显示肱骨头位于肩胛盂外后方，呈前后并列关系，失去正常对应关系，并经C T检查证实确诊为肩关节后脱位；2例漏诊患者均为单纯肩关节正位片。结论肩关节后脱位患者，正位片易漏诊，虽有异常，易被忽视，斜位片征象明显，能确定诊断，应列为常规检查。

Objective To explore the diagnostic methods of the posterior dislocation of the shoulders and its features on X‐ray films .Methods We analysed 12 cases of posterior dislocation of the shoulders .11 of them undetrtook X‐ray exami‐nation including both anterioposterior position and oblique position ,and were all confirmed by CT ;1 of them only under‐took examination with anterioposterior position ,and was restorated when undertook with oxter position .Results Abnor‐mities could be displayed on the anterioposterior radiograph .On oblique radiograph ,we can see caput humeri and glenoid cavity lost their normal relationship .2 cases of missed diagnosis were both on anterioposterior radiograh .Conclusion The posterior dislocation of the shoulders was often missed diagnois on anterioposterior radiograph .Whereas ,it has distincted symptoms on oblique radiograph ,which should be set as routine examination .
