Sonography is a simple technique which is currently employed in the study of rotator cuff lesions in the shoulder. A comparative US and arthrographic study was carried out on 52 patients with a "painful shoulder", to evaluate US yield in this pathologic condition. Arthrography was positive for a rotator cuff lesion in 31/52 cases (25 full-thickness and 6 incomplete lesions) and demonstrated associated conditions (capsulitis, chondral lesions, lesions of the long head of biceps, capsulo-ligamentous hypotonia, effusions) in 11 case. Arthrographic findings were negative in 10 cases. US demonstrated a lesion in 25/31 of positive arthrographic cases, and it was negative in 3/6 incomplete lesions. In 7/11 patients US yielded additional information as to associated conditions. US false-positives were 3/10, while in the extant 7/10 cases US was negative too. Thanks to its high sensitivity and specificity (80% and 70%, respectively, in our series), US appears as a valuable diagnostic complement to arthrography; the former may even replace the latter in those cases where conservative treatment is expected.
超声检查是一种简单的技术，目前用于肩部肩袖损伤的研究。对52例“肩部疼痛”患者进行了超声与关节造影的对比研究，以评估超声检查在这种病理状况下的诊断价值。关节造影显示52例中有31例（25例全层损伤和6例不完全损伤）存在肩袖损伤，并在11例中显示出相关病症（囊炎、软骨损伤、肱二头肌长头损伤、关节囊韧带张力减退、积液）。关节造影结果在10例中为阴性。超声检查在关节造影阳性的31例中有25例显示有损伤，在6例不完全损伤中有3例为阴性。在11例中的7例患者中，超声检查提供了有关相关病症的更多信息。超声检查的假阳性为10例中的3例，而在其余7/10的病例中超声检查也为阴性。由于其高敏感性和特异性（在我们的系列研究中分别为80%和70%），超声检查似乎是关节造影的一种有价值的诊断补充；在预期进行保守治疗的情况下，前者甚至可以取代后者。
