The purpose of this study was to identify the relationship between scapula morphology and rotator cuff tears (RCT). Hundred seventeen shoulders with and 87 shoulders without RCTs were included in this retrospective study. The critical shoulder angle (CSA) and lateral acromion angle in the coronal view, and the acromial coverage angle (ACA) and coracoid and scapular spine angle (CSSA) in the sagittal view were evaluated using 3-dimensional computed tomography. The glenoid anterior tilt, anterior acromial projection angle (AAPA), coracoid process angle, scapular spine angle (SSA), and inferior angle angle (IAA) with respect to the scapular plane were measured in the sagittal view. In univariate logistic regression analysis, CSA, ACA, AAPA, SSA, and IAA were significantly greater in shoulders with RCTs, whereas CSSA was greater in shoulders without RCTs. In multivariate logistic regression analysis, CSA and IAA were greater in shoulders with RCT and were significantly associated with this condition (P=.00073, P=.0032). This study has shown us that RCTs were associated with a greater curvature of the scapular body and greater CSA and IAA.
本研究旨在探讨肩胛骨形态与肩袖撕裂（RCT）之间的关系。本回顾性研究纳入了 117 例伴 RCT 肩和 87 例无 RCT 肩。使用三维 CT 评估冠状位的临界肩角（CSA）和外侧肩峰角，以及矢状位的肩峰覆盖角（ACA）和喙突和肩胛脊柱角（CSSA）。在矢状位上测量了相对于肩胛平面的肩胛盂前倾角、前肩峰投影角（AAPA）、喙突角、肩胛脊柱角（SSA）和下角角（IAA）。在单变量逻辑回归分析中，伴 RCT 的肩 CSA、ACA、AAPA、SSA 和 IAA 显著更大，而无 RCT 的肩 CSA 更大。在多变量逻辑回归分析中，CSA 和 IAA 在伴 RCT 的肩中更大，与该疾病显著相关（P=.00073，P=.0032）。本研究表明，RCT 与肩胛骨体曲率增大及 CSA 和 IAA 增大有关。
