Abstract:Objective To explore the diagnostic value of high-frequency ultrasound and magnetic resonance imaging (MRI) in frozen shoulder. Methods Retrospective analysis was performed on 50 patients (totally 54 affected shoulders) who underwent shoulder ultrasound and MRI from December 2017 to July 2019. Frozen shoulder was the “gold standard” for clinical diagnosis, there were 29 cases (30 affected shoulders) in the frozen shoulder group and 21 cases (24 affected shoulders) in the non-frozen shoulder group. The imaging characters and diagnostic efficacy of ultrasound and MRI were analyzed. Results High-frequency ultrasound and MRI showed that the joint capsule thickening in the frozen shoulder group were higher than those in the non-frozen shoulder group, with highly statistically significant differences (all P < 0.01). The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of ultrasound diagnosis for frozen shoulder were 70.0%, 87.5%, 77.8%, 87.5%, and 70.0%, respectively; and the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of MRI diagnosis for frozen shoulder were 86.7%, 91.7%, 88.9%, 92.9%, and 84.6%, respectively. Conclusion High-frequency ultrasonic examination has high application value to frozen shoulder and can be used as an important method to diagnose frozen shoulder.
