Background Coronal and sagittal views of magnetic resonance imaging (MRI) were used to determine rotator cuff tear size and fatty infiltration, but these images were not enough to identify the tear shape. Purpose To correlate the preoperative axial MRI views and arthroscopic surgical findings to identify the two-dimensional shapes in rotator cuff tears. Material and Methods This study included 166 patients who underwent arthroscopic repair between 2015 and 2018. Preoperative coronal, sagittal, and axial MRI views were evaluated for tear size and geographic configuration in axial sections, and the length and the width were measured and were matched with arthroscopic surgical views by lateral portals. Results The agreement of axial MRI views with the arthroscopic view was 88.0% in crescent, 97.2% in longitudinal, 78.6% in massive, and 100% in rotator cuff tear arthropathy. The mean agreement rate of axial MRI views with arthroscopic view was 81.9%. Mean mediolateral and anteroposterior tear sizes on axial MRI were 16.68 mm and 19.33 mm, respectively. Mean mediolateral and anteroposterior tear sizes by arthroscopic view were 21.49 mm and 21.04 mm, respectively. Tear sizes by MRI axial images were 71.3% of arthroscopic view. SST/IST degenerative changes were noted in most patients with massive tears and rotator cuff arthropathy ( P = 0.001). Conclusion Rotator cuff tear shape on preoperative axial MRI view had close agreement (81.9%) with arthroscopic findings by lateral portal, and tear size by preoperative axial MRI views was 71.3% of that of arthroscopic view. Axial MRI views helped to predict the geometric tear shape of rotator cuff tears.

Background: This study was designed to evaluate characters of the rotator cuff tear (RCT) recognized after primary shoulder dislocation in patients older than 40. Methods: From 2008 to 2019, patients who visited two hospitals after dislocation were retrospectively reviewed. Inclusion criteria were patients over 40 who had dislocation, with magnetic resonance imaging (MRI) undergone. Exclusion criteria were patients who lost to follow-up, combined with any proximal humerus fracture, brachial plexus injury, and previous operation or dislocation history in the ipsilateral shoulder. Also patients who had only bankart or bony bakart lesion in MRI were excluded. We evaluated RCTs that were recognized by MRI after the primary shoulder dislocation with regard to tear size, degree, involved tendons, fatty degeneration, the age when the first dislocation occurred, and the duration until the MRI was evaluated after the dislocation. Results: Fifty-five RCTs were included. According to age groups, the tear size was increased in coronal and sagittal direction, the number of involved tendons was increased, and the degree of fatty degeneration was advanced in infraspinatus muscle. Thirty-two cases (58.2%) conducted MRI after 3 weeks from the first shoulder dislocation event. Conclusions: This group showed that the retraction size of the coronal plane was increased significantly and the fatty accumulation of the supraspinatus muscle had progressed significantly. Age is also a strong factor to affect the feature of RCT after the shoulder dislocation in patients over 40. And the delay of the MRI may deteriorate the degree of tear size and fatty degeneration.

Objective: To study on the value of conventional magnetic resonance imaging in the diagnosis of rotator cuff tear in comparison with surgery.Subjects and research methods: Cross-sectional descriptive study on 69 patients with rotator cuff lesions undergoing magnetic resonance imaging at Hanoi Medical University Hospital Departmentof Diagnostic Imaging, all patients have surgery after that.Results: Among the number of patients operated, the highest proportion was the complete tendon rupture group (accounting for 60.9%), followed by the full-thickness tear group (14.5%) and thearticular-surface tear group (14.5%). , the groups of synovial-surface tear, intrasubstance tear, simple tendinopathy accounted for the least percentage. Regarding post-operative comparison: For completetendon tear, the sensitivity of magnetic resonance is 100%, specificity is 95.7%; in full-thickness tear, the sensitivity and specificity of magnetic resonance were 100% and 98.7%. The sensitivityof conventional magnetic resonance in the diagnosis of partial tear such as articular-surface tears, synovial-surface tear is 50-60% and specificity is 74.9-98.7%.Conclusion: Routine magnetic resonance imaging is a valuable method in diagnosing rotator cuff tears. The sensitivity and specificity of magnetic resonance are high in the diagnosis of major tendon tears (complete and full-thickness tears) than in cases of partial tear (articular or synovial surface tear).
