摘　　要：目的：探讨ＣＴ空气－碘水双对比造影对诊断肩关节不稳定的临床意义。材料与方法：８例患者做肩前穿刺，分别注入７６％泛影葡胺４ｍｌ和过滤空气１０ｍｌ，在全身ＣＴ机上行肩关节扫描。结果：所有患者气－碘双对比造影ＣＴ表现均与术中所见一致。主要特征为：（１）盂唇前部变钝、撕脱、游离；（２）关节囊前部撕脱或者关节囊破裂；（３）关节囊松弛、囊腔扩大。结论：ＣＴ气－碘双对比造影可以明确诊断肩关节不稳定，并为肩关节不稳定的解剖修复提供重要的影像学信息。Purpose: To study clinical importance of double contrast CT arthrography in the diagnosis of shoulder instability. Materials and methods: Eight patients were diagnosed as having shoulder instability with double contrast CT. The technique involved injection of 4 ml, 76% urografin and 10 ml of room air through an anterior shoulder puncture. The CT images were obtained with the patients supine and prone position. Results: The results of the CT arthrography were confirmed during the surgical operation afterward. The characteristics of abnormal double constrast CT arthrograms. They included anterior labral tear: the rounded anterior glenoid labrum, detached anterior labrum and anterior labral fragment; anterior capsular stripping off the anterior scapular glenoid neck; and enlargement of anterior and posterior capsular cavity. Conclusion: The current CT arthrography provides important X ray information for both diagnosis of shoulder instability and anatomatic repair of shoulder instability.
