The aim of this study was to determine the relationship between rotator cuff tear (RCT) morphologic parameters and muscle atrophy and fatty infiltration, and patient-reported outcome measures, in patients with symptomatic full-thickness RCT.
Rotator cuff tear location, length, width, thickness, and musculotendinous junction position were assessed in 57 magnetic resonance imaging scans and correlated to the outcome measures using multivariate regression analysis.
Supraspinatus tendon tear length (odds ratio [OR], 2.218; 95% confidence interval [CI], 1.460-3.370), supraspinatus musculotendinous junction position (OR, 2.037; 95% CI, 1.322-3.137), and infraspinatus tendon tear width (OR, 2.371; 95% CI, 1.218-4.615) were identified as the strongest determinants of supraspinatus muscle atrophy, supraspinatus muscle fatty infiltration, and infraspinatus muscle fatty infiltration, respectively.
The extent of supraspinatus tendon and musculotendinous junction retraction influences the development of supraspinatus muscle atrophy and fatty infiltration, whereas the extent of infraspinatus tendon tear width influences the development of infraspinatus muscle fatty infiltration. Morphologic parameters defining RCT at magnetic resonance imaging did not correlate with clinical shoulder function scores.
本研究旨在确定有症状的全层肩袖撕裂（RCT）患者的肩袖撕裂形态学参数与肌肉萎缩、脂肪浸润以及患者报告的结局指标之间的关系。
对57例磁共振成像扫描进行肩袖撕裂位置、长度、宽度、厚度和肌腱交接处位置评估，并使用多变量回归分析将其与结局指标相关联。
分别确定冈上肌腱撕裂长度（优势比[OR]，2.218；95%置信区间[CI]，1.460 - 3.370）、冈上肌腱交接处位置（OR，2.037；95%CI，1.322 - 3.137）和冈下肌腱撕裂宽度（OR，2.371；95%CI，1.218 - 4.615）分别是冈上肌萎缩、冈上肌脂肪浸润和冈下肌脂肪浸润的最强决定因素。
冈上肌腱和肌腱交接处回缩程度影响冈上肌萎缩和脂肪浸润的发展，而冈下肌腱撕裂宽度影响冈下肌脂肪浸润的发展。磁共振成像中定义RCT的形态学参数与临床肩部功能评分无关。
