Abstract：
UNASSIGNED: The morphology of the suprascapular notch (SSN) and the ossification of the superior transverse suprascapular ligament (STSL) are risk factors for injury of the suprascapular nerve (SN) during arthroscopic shoulder procedures. The purpose of the current study was to compare preoperative clinical and radiologic characteristics between patients with and without STSL ossification and to evaluate SSN morphology in patients who underwent arthroscopic rotator cuff repair using a 3-dimensional (3D) reconstructed model.
UNASSIGNED: Patients who underwent arthroscopic rotator cuff repair and were given a computed tomography (CT) scan from March 2018 to August 2019 were included in this study. Patients were divided into 2 groups: those without STSL ossification (group I) and those with STSL ossification (group II). Tear size of the rotator cuff and fatty infiltration of rotator cuff muscles were assessed in preoperative magnetic resonance imaging. The morphology of the SSN was classified following Rengachary\'s classification. The transverse and vertical diameters of the SSN and the distances from anatomical landmarks to the STSL were measured. All measurements were completed using a 3D CT reconstructed scapula model.
UNASSIGNED: A total of 200 patients were included in this study. One hundred seventy-eight patients (89.0%) without STSL ossification were included in group I, and 22 patients (11.0%) with STSL ossification were included in group II. Group II showed a significantly advanced age (61.0 ± 7.4 vs. 71.0 ± 7.3 years, p < 0.001) and a shorter transverse diameter of SSN (10.7 ± 3.1 mm vs. 6.1 ± 3.7 mm, p < 0.001) than group I. In the logistic regression analysis, age was an independent prognostic factor for STSL ossification (odds ratio, 1.201; 95% confidence interval, 1.112-1.296; p < 0.001). Patients in type VI showed significantly shorter transverse diameters than other types (p < 0.001). The patient with type I showed a significantly shorter distance from the articular surface of the glenoid to the SSN than those with other types (p < 0.001).

摘要：
■肩胛骨上切迹（SSN）的形态和肩胛骨上横韧带（STSL）的骨化是肩关节镜手术中肩胛骨上神经（SN）损伤的危险因素。本研究的目的是比较有和没有STSL骨化的患者的术前临床和放射学特征，并使用3维（3D）重建模型评估接受关节镜肩袖修复的患者的SSN形态。
■从2018年3月至2019年8月接受关节镜肩袖修复并接受计算机断层扫描（CT）扫描的患者被纳入本研究。患者分为两组：无STSL骨化的患者（I组）和有STSL骨化的患者（II组）。在术前磁共振成像中评估肩袖的撕裂大小和肩袖肌肉的脂肪浸润。SSN的形态按照Rengachary的分类进行分类。测量了SSN的横向和垂直直径以及从解剖标志到STSL的距离。所有测量均使用3DCT重建的肩胛骨模型完成。
■本研究共纳入200例患者。第一组中纳入78例(89.0%)无STSL骨化,22例(11.0%)STSL骨化患者被纳入II组。II组显示出明显的高龄（61.0±7.4vs.71.0±7.3年，p<0.001)和较短的SSN横向直径(10.7±3.1mmvs.6.1±3.7mm,p<0.001)比I组好。在逻辑回归分析中，年龄是STSL骨化的独立预后因素(比值比，1.201；95%置信区间，1.112-1.296；p<0.001）。VI型患者的横向直径明显短于其他类型（p<0.001）。与其他类型的患者相比，I型患者从关节盂关节面到SSN的距离明显更短（p<0.001）。
■在三维形态分析中，在接受关节镜肩袖修复术的患者中,年龄是与STSL骨化相关的独立因素.VI型的横向直径明显短于其他类型。与其他类型相比，I型显示从关节盂关节面到SSN的距离明显更短。
