Abstract
Supraspinatus tendon injury is a common clinical shoulder joint disease and is one of the most common causes of shoulder pain and dysfunction. Supraspinatus tendon injury will lead to articular cartilage injury and degeneration, then cause joint disease, seriously affect the quality of life of patients, and bring a huge burden to the family and society. This paper mainly studies and evaluates the application value of special signs of shoulder joint and indirect MR imaging in the diagnosis of supraspinatus tendon injury. Through a series of special examinations for the diagnosis of supraspinatus tendon injury in 90 patients, including zero degree abduction resistance test, arm drop test, Jobe test, Neer sign, and Hawkins sign, all patients in the study underwent indirect magnetic resonance imaging of the shoulder joint. Finally, arthroscopic examination results were used as the “gold standard” to evaluate and analyze the diagnosis. The results showed that among the special signs, the specificity of the falling-arm test was the highest (72.2%) in the diagnosis of full-thickness supraspinatus tendon injury. Hawkins sign had the highest sensitivity (84.0%). In the diagnosis of partial supraspinatus tendon injury, the specificity of the Jobe test was the highest, which was 66.6%. The Neer sign had the highest sensitivity of 50.0%. In the diagnosis of full-thickness supraspinatus tendon injury, there was no significant difference in sensitivity between indirect MRI and Hawkins sign, but the diagnostic specificity of indirect MRI was higher than that of special sign examination. In the diagnosis of partial supraspinatus tendon injury, the sensitivity and specificity of indirect MR imaging are higher than those of special sign examination.
Highlights
Rotator cuff injury has attracted much attention since Smith first put forward the concept of rotator cuff injury in 1834.ese concerns are due to the research interest of scholars, and due to the needs of a large number of patients. e study found that the incidence of partial or fullthickness rotator cuff injury increased significantly after age 50, exceeding 50 percent in people over 70 and more than 80 percent in people over 80
After more than one year of follow-up, changes of rotator cuff injury is examined with shoulder arthrography. e results showed that only 4 patients had obvious healing of injured rotator cuff. e extent of injury was reduced in four patients
Special signs of shoulder and indirect magnetic resonance angiography were used as screening diagnostic methods to be evaluated, and the results of shoulder arthroscopy were compared with the “gold standard” diagnostic results and statistically analyzed
Summary
Rotator cuff injury has attracted much attention since Smith first put forward the concept of rotator cuff injury in 1834. A variety of imaging examinations provide useful diagnostic information from different perspectives, and how to choose efficient and reliable diagnostic techniques to help the clinical screening and diagnosis of supraspinatus tendon injury has become one of the hot spots of attention and research. Xiao et al discussed the diagnostic value of magnetic resonance arthrography of the shoulder for partial rotator cuff tear [3]. Is paper mainly studies and evaluates the application value of special signs of shoulder joint and indirect MR imaging in the diagnosis of supraspinatus tendon injury
