摘　　要：目的　总结分析盂肱关节不稳在CT关节造影上的表现。方法　 16例经关节镜手术检查证实病例 ,对盂唇撕裂 ,关节囊撕脱 ,关节盂骨折等在CT关节造影上表现特点进行总结分析。结果　关节内损伤包括盂唇撕裂 ,见盂唇内有造影剂充盈 ;关节盂唇软骨剥脱 ,正常关节软骨三角形结构消失 ,骨性关节盂裸露于关节囊内 ;关节囊撕脱 ,表现有关节囊腔扩大 ,关节囊附着点位置改变等 ;以及骨性关节盂缘骨折 ,肱骨外上方压缩骨折等。结论　肩盂肱关节CT造影对比性好 ,断层图像无重叠 ,可清晰显示出关节内损伤 。Objective To evaluate the manifestations of glenohumeral instability on CT arthrography.Methods 16 cases of glenohumeral instability were examined both by CT arthrography and arthroscopy and to analyze the manifestations on CT arthrography.Results Intraarticular injury included labral tear, capsular stripping or laxity, anterior glenoid fracture and lateral posterior humeral head impacted fracture.Conclusion Shoulder arthrography has good contrast, and because the imaging no overlaps, can clearly show the intraarticular injures. It is a good examine method of glenohumeral instability.
