| 目的 探讨超声诊断髋关节镜二次翻修患者前上盂唇撕裂的临床价值。方法 回顾性分析23例髋关节镜二次翻修患者的超声和MRI检查资料，以关节镜手术为金标准，评估超声诊断髋关节镜二次翻修患者前上盂唇撕裂的敏感性、特异性、阳性预测值、阴性预测值和准确率，并与MRI诊断效能比较。结果 准确率准确率超声诊断前上盂唇撕裂敏感性、特异性和准确率分别为30%、100%、39.1%（标准1）和45%、100%、52.2%（标准2），MRI诊断前上盂唇撕裂敏感性、特异性和准确率分别为30%、100%、39.1%（标准1）和70%、33.3%、65.2%（标准2）。超声检查与MRI检查在评估前上盂唇撕裂敏感性和准确率比较，差异均无统计学意义。结论 联合多个超声征象和应用MRI相对宽松指征可提高髋关节镜二次翻修患者前上盂唇撕裂诊断敏感性和准确率趋势。 |

| Abstract: |
| Objective To explore the value of ultrasound in the diagnosis of anterosuperior acetabular labral tears in patients underwent revision hip arthroscopy.Methods A total of 23 patients ［（ 8 males and 15 females，average age was （ 37.4±11.9） years］underwent revision hip with Ultrasound and MRI data were analyzed retrospectively，including 13 left hip joints and 10 right hip joints.Using arthroscopy as golden standard，the sensitivity，specificity，positive predictive value，negative predictive value and accuracy between ultrasound and MRI were calculated and compared.Results The sensitivity，specificity and accuracy by ultrasound diagnostic criterias 1 and 2 were 30%、100%、39.1% and 45%、100%、52.2% respectively.The sensitivity，specificity and accuracy by MRI diagnostic criterias 1 and 2 were 30%、100%、39.1% and 70%、33.3%、65.2% respectively.There was no statistically significant difference in sensitivity and accuracy of labrum tear detection between US and MRI （ P =0.180-0.549）.Conclusion There is a trend towards improved sensitivity and accuracy for anterosuperior acetabular labral tear with combining multiple ultrasonic signs and applying relatively loose indications on MRI. |
