MRI与超声检查对肱骨近端骨折合并肩袖损伤的临床价值
Clinical value of MRI and ultrasound in proximal humerus fracture complicated with rotator cuff injury
摘要
Abstract
Objective To evaluate the application and value of MRI and US in the diagnosis of proximal humerus fracture combined with rotator cuff injury.Methods Taken the results of surgical exploration as the"gold standard",121 patients with suspected rotator cuff injury and proximal humerus fracture admitted to hospital from February 2022 to February 2025 were examined by MRI and US respectively,and the effects of different scanning methods on the detection of different tendon injuries,rotator cuff injuries and diagnostic indicators were compared.Results There was no significant difference in the incidence of supraspinatus tendon injury,infraspinatus tendon injury,subscapularis tendon injury,and teres minor tendon injury between the two scanning methods(P>0.05).However,there was a significant difference in the incidence of no rotator cuff injury(3.31%vs 4.13%,P<0.05),with a Kappa consistency coefficient of 0.130.There was no significant difference in the incidence of full-thickness tear,ligament injury,bone injury,and partial tear(P>0.05),but there was a significant difference in the total number(96.69%vs 94.21%,P<0.05),with a Kappa consistency coefficient of 0.622.Meanwhile,the diagnostic accuracy rate(0.9528),sensitivity(0.9600),negative predictive value(0.1667),and Youden index(0.9600)of US for diagnosing rotator cuff injury were lower than those of MRI(0.9603,0.9677,0.2000,0.9677 respectively);the missed diagnosis rate of US for rotator cuff injury(0.0400)was higher than that of MRI(0.0323);the specificity(1),positive predictive value(0.9917),and misdiagnosis rate(0.00)of US for rotator cuff injury were consistent with those of MRI.Conclusion The two examination modalities have their own advantages and disadvantages,and the appropriate examination method should be selected according to the patient's specific situation in the clinic.关键词
