The purpose of this study was to determine the accuracy of sonography in the detection of rotator cuff tears. Eighty-one patients were referred by orthopedic specialists because of a clinical suspicion of rotator cuff tear. The standards of comparison were arthrography in 79 cases and surgery in two cases. The sonographic technique used was based on a review of the literature and experience gained by scanning normal subjects. The sonographic criteria for the diagnosis of a complete rotator cuff tear were a focal defect in the cuff or complete absence or nonvisualization of the cuff. All sonograms were interpreted prospectively without knowledge of arthrographic or surgical results. With arthrography as the standard of comparison for the diagnosis of rotator cuff tear, sonographic results included 15 true-positives, 52 true-negatives, eight false-negatives, and four false-positives. With surgery as the standard of comparison, the results were one true-positive and one true-negative sonogram. The sensitivity of sonography in detecting rotator cuff tear was 0.67, the specificity was 0.93, and the accuracy was 0.85. Our study found lower sensitivity and accuracy results for shoulder sonography than have been previously reported.
本研究的目的是确定超声检查在检测肩袖撕裂方面的准确性。81名患者因临床怀疑肩袖撕裂而被骨科专家转诊。比较标准在79例中为关节造影，2例中为手术。所采用的超声检查技术基于对文献的回顾以及对正常受试者进行扫描所获得的经验。诊断完全性肩袖撕裂的超声标准为肩袖中的局灶性缺损或肩袖完全缺失或不可见。所有超声图像均在不知关节造影或手术结果的情况下进行前瞻性解读。以关节造影作为诊断肩袖撕裂的比较标准，超声检查结果包括15例假阳性、52例假阴性、8例假阴性和4例假阳性。以手术作为比较标准，结果为1例假阳性和1例假阴性超声图像。超声检查检测肩袖撕裂的敏感性为0.67，特异性为0.93，准确性为0.85。我们的研究发现，肩部超声检查的敏感性和准确性结果低于先前报道的结果。
