【摘要】 目的探讨肩关节后脱位X线征象及其临床应用价值。方法分析43例以手法复位及手术治疗确诊为肩关节后脱位患者(病例组)的X线征象(边缘征、槽线征、灯泡征、半月缺乏征、Mouzopoulos征、肱骨头侧方后移),并与对照组(60例无肩关节后脱位者)相比较。计算肩关节后脱位X线征象诊断的特异性及敏感性。结果病例组与对照组X线表现为边缘征、槽线征、灯泡征、半月缺乏征、Mouzopoulos征、肱骨头侧方后移的差异具有统计学意义(P<0.01)。肱骨头侧方后移的准确度最高(98.1%),其次是槽线征(89.4%),Mouzopoulos征准确度最低(69.2%);任意3种或5种征象同时出现的准确度较高,均为68.3%,任意4种征象出现的准确度次之,为67.3%。结论疑有肩关节后脱位者如X线出现3个肩关节后脱位征象,则诊断其肩关节后脱位的正确率较高。更多还原

【Abstract】 Objective To investigate the X-ray signs of posterior dislocation of shoulder joint and the clinical significance thereof. Methods A total of 44 cases diagnosed with posterior dislocation of shoulder by manual reduction and operation were collected as the Case Group while 60 normal persons without posterior dislocation of shoulder were selected as the Control Group. The X-ray signs of posterior dislocation of shoulder, including marginal sign, trough-line sign, bulb sign, absence of the half-moon sign, mouzopoulos sign and lateral displacement of humeral head of the Case Group were analyzed and compared with those of the Control Group. The specificity and sensitivity of diagnosis of X-ray signs of posterior dislocation of shoulder were calculated. Results There were statistical differences in X-ray manifestations of the Case Group and the Control Group, including marginal sign, trough-line sign, bulb sign, absence of the half-moon sign, mouzopoulos sign and lateral displacement of humeral head(P<0.01). The accuracy of lateral displacement of humeral head was the highest(98.1%), followed by trough-line sign(89.4%), and the accuracy of mouzopoulos sign was the lowest(69.2%). The accuracy of the concurrence of any three or five signs was relatively higher(68.3%), followed by the concurrence of any four signs(67.3%). Conclusion The X-ray signs can be of certain value in the clinical diagnosis of posterior dislocation of shoulder. If a patient suspected of posterior dislocation of shoulder has 3 signs, the accuracy of diagnosis of posterior dislocation of shoulder will be greatly improved.更多还原
