Bili Liu, Dan Ge, Yue Shan, Yanping Li, Juan Lv, Shuzhi Gan Department of Ultrasound, Hangzhou TCM Hospital Affiliated to Zhejiang Chinese Medical University, Hangzhou, Zhejiang Province, 310007, People’s Republic of ChinaCorrespondence: Bili Liu, Department of Ultrasound, Hangzhou TCM Hospital Affiliated to Zhejiang Chinese Medical University, No. 453 Stadium Road, Xihu District, Hangzhou, Zhejiang Province, 310007, People’s Republic of China, Tel +86-057185827841, Email [email protected]: Based on the analysis of the images of acromial slide, we explored the application of percutaneous ultrasound-guided subacromial bursography (PUSB) on rotator cuff tear (RCT) in diagnosing elderly patients with shoulder pain.Methods: Eighty-five patients who were clinically diagnosed with RCT and underwent PUSB examination in the department of ultrasound in our hospital were enrolled as the subjects. Independent samples t-test was used to analyze the general characteristics. Based on the gold standard of shoulder arthroscopy, the diagnostic efficacy of ultrasound, magnetic resonance imaging (MRI), and PUSB was evaluated. The sensitivity, specificity, positive and negative predictive values, and accuracy were calculated as well. The consistency of these techniques with shoulder arthroscopy in diagnosing the RCT stage was additionally compared using Kappa test.Results: In patients with large full-thickness RCT, the 100% detection rate was achieved by the techniques of ultrasound, MRI, and PUSB. For patients with small full-thickness RCT, the detection rate of PUSB (100%) was evidently higher than those of ultrasound and MRI. Similar results were shown in the detection rates of patients with bursal-side partial-thickness RCT (90.5%) and articular-side partial-thickness RCT (86.9%). More importantly, the sensitivity, specificity, and accuracy of PUSB in patients with both full-thickness RCT and partial-thickness RCT were significantly better than those of ultrasound and MRI.Conclusion: PUSB has a better efficacy in the detection of RCT than ultrasound and MRI, showing its feasibility as an important imaging method to evaluate the degree of RCT.Keywords: rotator cuff tear, percutaneous ultrasound-guided subacromial bursography, shoulder pain, acromial slide cystography, diagnosis
