| 目的 探讨术前超声和MRI对肩胛下肌腱撕裂的诊断价值。方法 回顾性纳入2019年1月至2020年6月在我科初次行肩关节镜手术的111例，收集病人术前超声和MRI报告，与术中手术资料进行比较，分析超声与MRI诊断肩胛下肌腱撕裂的敏感性、特异性、准确性以及阳性预测值、阴性预测值。结果 本组33.3％（37/111）病人术中证实有肩胛下肌腱撕裂。超声诊断出19例肩胛下肌腱撕裂，敏感性：51.35%，特异性：100.00%，阳性预测值：100.00%，阴性预测值：80.43%；在83.78%的病例中，超声能够准确地识别肩胛下肌腱撕裂。MRI诊断出13例肩胛下肌腱撕裂，敏感性：35.14%，特异性：100.00%，阳性预测值：100.00%，阴性预测值：75.51%，准确性：78.38%。对于Ⅰ型肩胛下肌腱撕裂，超声诊断的敏感性：40.00%，特异性：100.00%，而MRI诊断的敏感性：13.33%，特异性：100.00%。结论 尽管有一定的局限，超声在预测肩胛下肌腱撕裂方面的效能明显优于MRI，是术前可供选择的一种有效检查。 |

| Objective To explore the diagnostic value of preoperative ultrasound and MRI for subscapular tendon tear. Methods A total of 111 cases of primary shoulder arthroscopy in our department from January 2019 to June 2020 were retrospectively included. The preoperative ultrasound/MRI reports were collected, and compared with those during the operation. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of ultrasound/MRI in the diagnosis of subscapular tendon tear were analyzed. Results In this study group, a subscapular tendon tear was intraoperatively confirmed in 33.3%(37/111) of patients. In overall subscapular tendon tear, for ultrasound, there was a sensitivity of 51.35%, specificity of 100.00%, positive predictive value of 100.00%, negative predictive value of 80.43%. In 83.78% of cases, ultrasound could identify subscapular tendon tears accurately. MRI had an overall sensitivity of 35.14%, specificity of 100.00% and accuracy of 78.38%. The positive predictive value was 100.00%, and the negative predictive value was 75.51%. For type I subscapular tendon tear, the sensitivity and specificity for ultrasound and MRI was 40.00% and 100.00%, 13.33% and 100.00%, respectively. Conclusion Although there are some limitations, ultrasound is superior to MRI in predicting subscapular tendon tears, which is an effective preoperative examination. |
