Purpose: The purpose of this study was to investigate the relationship between the superior capsule tear patterns and synovitis with subacromial pathologies, such as bursal-sided rotator cuff tear and subacromial impingement syndrome. Methods: Fifty patients who underwent arthroscopic treatment for isolated bursal-sided tear were included in the study. Fifty more patients who underwent arthroscopic treatment for isolated Superior Labrum Anterior Posterior (SLAP) 2 lesion without pathology in the rotator cuff were included in the control group. Firstly, superior capsule tear and common synovitis on the rotator cable were assessed during glenohumeral joint examination. Coracoacromial Ligament (CAL) degeneration grading was performed according to the Royal Berkshire Hospital classification. Bursal-sided partial tear grading was done using Ellman classification. Whether or not there was a relationship between synovitis, classic capsule tear, plus reverse flap capsule tear, and partial bursal-sided tear existence. Results: There were 21 patients with reverse flap capsule tear in the study group and 3 patients in the control group. In addition, there were 13 patients with synovitis in the study group and 4 in the control group. Compared to the control group, there was also a significant positive correlation in the presence of both synovitis and reverse flap capsule tear with the presence of bursal-sided tear in the study group ( p = 0.000). There was, however, no significant difference between the presence of classical capsule tear and the presence of bursal-sided tear ( p = 0.485). Conclusion: This study shows that the presence of reverse flap capsule tear and synovitis was associated with partial bursal-sided tears. Therefore, if the reverse flap capsule tear or synovitis is detected in the superior capsule, the rotator cuff should be evaluated in more detail during subacromial bursoscopy in order not to miss a bursal-sided partial cuff tear.

Purpose: Coracoid morphology has been related to coracoid impingement mainly resulting in anterior shoulder pain aggravated by forward flexion and internal rotation. However, the coracoid process morphology can also affect the inclination of the coracoacromial ligament and subsequently the subacromial space in the same way that acromial slope does. The purpose of this study was to evaluate the influence of the coracoid body–glenoid surface, coracoid tip–glenoid surface, and coracoid body–coracoid tip angles (coracoid inclination angles) on rotator cuff tears (RCTs). Methods: Fifty patients with documented RCT and 50 patients with normal rotator cuff (control) were included. The coracoid inclination angles were determined in both groups by measuring on computed tomography scans the angle created by the coracoid body and the glenoid surface (A1), the angle created by the coracoid tip and the glenoid surface (A2), and the angle created by the coracoid body and the coracoid tip (A3). Results: All angles were significantly lower in the RCT group compared to the control group: mean A1 angle of 49.7° and 54.61°, respectively ( p = 0.011); mean A2 angle of 76.45° and 93.6°, respectively ( p < 0.001); and mean A3 angle of 132.33° and 144.34°, respectively ( p < 0.001). Conclusions: Decreased coracoid body–glenoid surface, coracoid tip–glenoid surface, and coracoid body–coracoid tip angles are associated with RCT. Decreased angles may reduce subacromial space by projecting the coracoacromial ligament more vertically.

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.
