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 ,是肩盂肱关节不稳的一种有效准确的检查方法
Objective To summarize and analyze the performance of glenohumeral instability in CT arthrography. Methods Sixteen cases confirmed by arthroscopic surgery were analyzed. The features of labrum tear, capsulotomy, glenoid fracture and other articular synovial lesions were summarized. Results intra-articular injury including labrum tear, see the labrum with contrast agent filling; joint labrum cartilage exfoliation, the normal triangular structure of articular cartilage disappeared, bony joint bare exposed in the joint capsule; joint capsule avulsion, the performance of the joints Capsule expansion, changes in the location of joint capsule attachment, etc .; and bone joint glenoid bone fracture, humeral compression fractures above. Conclusions CT glenography of shoulder glenohumeral joint is good, the images of the gonads do not overlap, and it can clearly show the intra-articular injury. It is an effective and accurate method for the diagnosis of shoulder glenohumeral instability
