The glenohumeral joint was studied in 25 cadavers and 136 patients using computed arthrotomography (CAT) and conventional arthrotomography (AT) to assess shoulder instability. Cadaver shoulders were injected with air or latex, sectioned with a band saw, and normal articular anatomy outlined. CAT was performed in 81 patients and characterized the glenoid labrum as normal, abnormal, or detached in 38 of the 44 patients who had surgery or arthroscopy (sensitivity, 96%; accuracy, 86%). Hill-Sachs defects were seen in 20 out of 29 patients with anterior labral abnormalities, while bicipital tendon abnormalities were evident on CAT in 6. Of 55 patients who had AT, the status of the labrum was clarified in 13 of the 16 patients who had surgery or arthroscopy (sensitivity, 86%; accuracy, 81%). Both methods can characterize the labrum; however, CAT is more comprehensive and appears ideal for both detection of Hill-Sachs defects and imaging the bicipital tendon. CAT requires less technical expertise and radiation than AT and is tolerated better by patients in pain.
使用计算机关节断层扫描（CAT）和传统关节断层扫描（AT）对25具尸体和136例患者的盂肱关节进行研究，以评估肩部不稳。向尸体肩部注入空气或乳胶，用带锯进行切片，并勾勒出正常关节解剖结构。对81例患者进行了CAT检查，在44例接受手术或关节镜检查的患者中，有38例的关节盂唇被判定为正常、异常或分离（敏感性为96%；准确性为86%）。29例前盂唇异常患者中有20例可见Hill-Sachs损伤，6例患者的肱二头肌腱异常在CAT上表现明显。在55例接受AT检查的患者中，16例接受手术或关节镜检查的患者中有13例的盂唇情况得以明确（敏感性为86%；准确性为81%）。两种方法都能对盂唇进行特征描述；然而，CAT更全面，似乎对于检测Hill-Sachs损伤和对肱二头肌腱进行成像都很理想。与AT相比，CAT所需的技术专长和辐射更少，疼痛患者对其耐受性更好。
