“…The radiological parameters used in this study have been evaluated in patients with impingement syndrome and degenerative SSP tears in the literature. Studies in the literature report different results, from showing no significant difference to a healthy control [19] to studies that show significantly higher CSA and AI in patients with impingement syndrome and/or degenerative SSP tear [4,5].…”

Background The etiology of degenerative supraspinatus tendon (SSP) tear is still subject to discussion. Objectives Our objective was to correlate clinical, radiological, and intraoperative signs of mechanical outlet impingement in patients with degenerative SSP tears. Materials and methods This prospective study included 100 patients with degenerative SSP tears that required surgery. Preoperatively, clinical impingement signs and radiological parameters (critical shoulder angle [CSA], acromion type according to Bigliani, acromion index [AI]) were recorded. Intraoperatively, the extent of the rupture and grinding marks on the bottom of the acromion were assessed. Results Of the 100 patients, 59 had clinical impingement signs preoperatively; 90 patients had at least one positive radiological sign (CSA > 35°, AI > 0.67, acromion type II or III). In 23 patients a partial tear, in 55 patients a full thickness tear, and in 22 patients an additional infraspinatus tendon tear were found. In 10 cases no grinding marks at the bottom of the acromion during arthroscopy were found. In 75 cases moderate grinding marks and in 15 cases severe marks with bare bone at the bottom of the acromion were found. There was no statistically significant correlation between preoperative impingement signs and arthroscopic grinding marks (p = 0.83) or between clinical signs and radiological parameters (p = 0.44). There was no significant correlation between extent of the rupture, extent of grinding marks or radiological impingement parameters (p = 0.16; p = 0.26). Conclusion We could not verify a correlation between clinical and radiological impingement sign and arthroscopic impingement parameters. Based on our study, degenerative SSP tear cannot be characterized as the result of a mechanical outlet impingement.

Diagnostic value of the axial view of magnetic resonance imaging to identify two-dimensional shapes of full-thickness rotator cuff tears

et al. 2020

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.

“…They proposed that heel type osteophytes could be one of the factors related to induce rotator cuff tears. Conversely, another study by Sasiponganan et al [ 18 ] reported that subacromial spur, including heel type and traction type, was associated only with subscapular tear among rotator cuff tear. However, this study had its limitation, as it did not analyze according to the type of spur.…”

Background: The present study was undertaken to evaluate the relationship between location of the rotator cuff tear and shape of the subacromial spur.Methods: Totally, 80 consecutive patients who underwent arthroscopic repair for partial thickness rotator cuff tear were enrolled for the study. Bigliani’s type of the acromion, type of subacromial spur, and location of partial thickness tear of the rotator cuff were evaluated using plain X-ray and magnetic resonance imaging. We then compared the groups of no spur with spur, and heel with traction spur.Results: Of the 80 cases, 25 cases comprised the no spur group, and 55 cases comprised the spur group. There was a significant difference in type of tear (p=0.0004) between these two groups. Bursal side tears were significantly greater (odds ratio=6.000, p=0.0007) in the spur group. Subjects belonging to the spur group were further divided into heel (38 cases) and traction spur (17 cases). Comparing these two groups revealed significant differences only in the type of tear (p=0.0001). Furthermore, the heel spur had significantly greater bursal side tear (odds ratio=29.521, p=0.0005) as compared to traction spur.Conclusions: The heel spur is more associated to bursal side tear than the traction spur, whereas the traction spur associates greater to the articular side tear.
