Our study assessed the accuracy of shoulder ultrasonography in detecting complete and partial rotator cuff tears. We performed a prospective study in 24 patients scheduled for shoulder arthroscopy for impingement, partial-thickness or full-thickness (complete) rotator cuff tears, adhesive capsulitis, or arthritis. Before surgery, all patients underwent diagnostic shoulder ultrasonography followed by a shoulder arthroscopy with examination of the rotator cuff. The arthroscopic findings of rotator cuff integrity were compared with the diagnoses made from ultrasonography. The ultrasonographer was not blinded to the history and examination findings, and the surgeon was not blinded to the results of the ultrasonography. Ultrasound had sensitivity and specificity rates of 80% and 100%, respectively (positive and negative predictive rates of 100% and 88%), in the diagnosis of full-thickness rotator cuff tears and sensitivity and specificity rates of 71% and 100%, respectively (positive and negative predictive values of 100% and 88%), for partial-thickness tears. Although the potential for bias exists in this study, the results suggest that diagnostic ultrasound is effective in the diagnosis of rotator cuff tears.
我们的研究评估了肩部超声检查在检测肩袖全层和部分撕裂方面的准确性。我们对24例计划进行肩关节镜检查的患者进行了一项前瞻性研究，这些患者因撞击症、部分厚度或全层（完全）肩袖撕裂、粘连性关节囊炎或关节炎而接受检查。手术前，所有患者均接受了肩部诊断性超声检查，随后进行了肩关节镜检查并对肩袖进行了检查。将肩袖完整性的关节镜检查结果与超声检查做出的诊断进行比较。超声检查人员知晓患者病史和检查结果，外科医生也知晓超声检查结果。超声诊断肩袖全层撕裂的敏感性和特异性分别为80%和100%（阳性和阴性预测率分别为100%和88%），诊断部分厚度撕裂的敏感性和特异性分别为71%和100%（阳性和阴性预测值分别为100%和88%）。尽管本研究存在偏倚的可能性，但结果表明诊断性超声在肩袖撕裂的诊断中是有效的。
