Abstract

Background: Shoulder injuries are one of the common sports injuries among various kinds of sports, almost third of the shoulder injuries occurs during sports. Glenohumeral instability and rotator cuff injuries are the most common types of shoulder injuries related to sports’ trauma. Aim of the work: To highlight the role of MR arthrography over conventional MRI in evaluation of sports related labral, ligamentous and tendentious glenohumeral injuries. Patients and Methods: In our study thirty-four patients suffering from shoulder pain after sport’s related trauma, were referred to our radiology department to do conventional MRI as well as MR arthrography. Arthroscopy was done as a gold standard. Results: In our study MR arthrography was nonspecific in diagnosis of HAGL lesion. Regarding ALPSA lesion, three patients were diagnosed as ALPSA lesion on MR arthrography however, they were not detected by conventional MRI and all of them were detected by arthroscopy. Two patients were diagnosed as ALPSA lesion however were not diagnosed by either arthrography or conventional MRI (false negative), and hence MR arthrography lesion has sensitivity of 75 % and specificity of 100%. Conclusion: Both MR arthrography and conventional MRI were not accurate in diagnosis of HAGL lesions. MR arthrography is more accurate than Conventional MRI in diagnosis of SLAP lesions, Bankart lesions, partial supraspinatus tear, impingement, biceps tear, ALPSA and Hill sachs lesions. Both MR arthrography and conventional MRI had same accuracy in diagnosis of complete supraspinatus tear.
