Poster 213 The Diagnostic Accuracy of Special Tests for Rotator Cuff Tear

Objective. To explore the value of real-time dynamic ultrasound and magnetic resonance imaging (MRI) in the diagnosis of rotator cuff injury. Methods. From January 2020 to June 2021, the clinical data of 55 patients with rotator cuff injury were collected. All patients were examined by real-time dynamic ultrasound and MRI at the same time within two weeks before surgery, which was confirmed by arthroscopy. The value of real-time dynamic ultrasound, MRI, and the real-time dynamic ultrasound combined with MRI in the diagnosis of rotator cuff injury was evaluated. Results. Among the 55 patients with rotator cuff injury, real-time dynamic ultrasound showed full-thickness rotator cuff tear in 12 patients (21.82%), including type I in 2 patients (3.64%), type II in 6 patients (10.91%), and type III in 4 patients (7.27%), and partial rotator cuff tear in 31 patients (56.36%), including type IV in 16 patients (29.00%), type V in 5 patients (9.09%), and type VI in 10 patients (18.18%). MRI showed full-thickness rotator cuff tear in 12 patients (21.82%), including type I in 2 patients (3.64%), type II in 6 patients (10.91%), and type III in 4 patients (7.27%), and partial rotator cuff tear in 37 patients (67.27%), including type IV in 20 patients (36.36%), type V in 7 patients (12.73%), and type VI in 10 patients (18.18%). The combined examination showed full-thickness rotator cuff tear in 12 patients (21.82%), including type I in 2 patients (3.64%), type II in 6 patients (10.91%), and type III in 4 patients (7.27%), and partial rotator cuff tear in 39 cases (70.91%), including type IV in 21 cases (38.12%), type V in 7 patients (12.73%), and type VI in 12 patients (21.82%). The diagnostic accuracy of real-time dynamic ultrasound in complete tearing, partial tearing and the overall accuracy were 92.31%, 73.81% and 78.18%, respectively. The diagnostic accuracy of complete tear, partial tear and the overall accuracy of MRI were 92.31%, 88.00% and 89.09%, respectively. The diagnostic accuracy of complete tear and partial tear and overall accuracy in the real-time dynamic ultrasound combined with MRI were 92.31%, 95.24%, and 94.55%, respectively. The diagnostic accuracy and overall diagnostic accuracy of the combined examination of partial tears were higher than those of the real-time dynamic ultrasound and MRI examinations alone. Conclusion. Real-time dynamic ultrasound and MRI have high application value in the diagnosis of rotator cuff injury, and the combined diagnosis is conducive to improving the diagnostic accuracy of patients with partial tear.

Objective The objective of the study was to assess the accuracy of ultrasound examination for the diagnosis of rotator cuff tear and tendinosis performed by a short experienced operator, compared to magnetic resonance imaging (MRI) results. Method A total of 70 subjects suspected to have rotator cuff tear or tendinosis and planned for shoulder MRI were included in the study. Shoulder ultrasound was performed either before or after the MRI scan on the same day. Ultrasound operator had a short experience in performing an ultrasound of the shoulder. Ultrasound findings were correlated to MRI findings. Results Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for the diagnosis of tendinosis were 58%, 84%, 63%, 80%, and 75%, respectively, and it was 68%, 91%, 73%, 88%, and 85%, respectively, for the diagnosis of rotator cuff tear. Conclusions Sensitivity for diagnosing rotator cuff tear or tendinosis was moderate but had a higher negative predictive value. Thus, the ultrasound operator with a short experience in performing shoulder ultrasound had moderate sensitivity in diagnosing tendinosis or tears; however, could exclude them with confidence.

Background: Metabolic factors have been linked to tendinopathies, yet few studies have investigated the association between metabolic factors and lateral epicondylitis. Purpose: To evaluate risk factors for lateral epicondylitis, including several metabolic factors. Study Design: Case-control study; Level of evidence, 3. Methods: We evaluated 1 elbow in each of 937 volunteers from a rural region that employs many agricultural laborers. Each participant received a questionnaire, physical examinations, blood tests, simple radiographic evaluations of both elbows, magnetic resonance imaging of bilateral shoulders, and an electrophysiological study of bilateral upper extremities. Lateral epicondylitis was diagnosed using 3 criteria: (1) pain at the lateral aspect of the elbow, (2) point tenderness over the lateral epicondyle, and (3) pain during resistive wrist dorsiflexion with the elbow in full extension. Multivariable logistic regression analysis was used to calculate the odds ratios (ORs) and 95% CIs for various demographic, physical, and social factors, including age, sex, waist circumference, dominant-side involvement, smoking habit, alcohol intake, and participation in manual labor; the comorbidities of diabetes, hypertension, thyroid dysfunction, metabolic syndrome, ipsilateral biceps tendon injury, ipsilateral rotator cuff tear, and ipsilateral carpal tunnel syndrome; and the serologic parameters of serum lipid profile, glycosylated hemoglobin A1c, level of thyroid hormone, and high-sensitivity C-reactive protein. Results: The prevalence of lateral epicondylitis was 26.1% (245/937 participants). According to the multivariable logistic regression analysis, female sex (OR, 2.47; 95% CI, 1.78-3.43), dominant-side involvement (OR, 3.21; 95% CI, 2.24-4.60), manual labor (OR, 2.25; 95% CI, 1.48-3.43), and ipsilateral rotator cuff tear (OR, 2.77; 95% CI, 1.96-3.91) were significantly associated with lateral epicondylitis ( P < .001 for all). No metabolic factors were significantly associated with lateral epicondylitis. Conclusion: Female sex, dominant-side involvement, manual labor, and ipsilateral rotator cuff tear were found to be risk factors for lateral epicondylitis. The study results suggest that overuse activity is more strongly associated with lateral epicondylitis than are metabolic factors.
