背景 肩袖撕裂 (RCT) 中骨化的肩胛上横韧带 (OSTSL) 的患病率尚未确定。本研究的目的是评估随机对照试验中 OSTSL 的患病率，并调查 OSTSL 形态与冈上肌萎缩之间的相关性。方法我们分析了总共 213 名随机对照试验患者，他们在关节镜手术前进行了 3 维 (3D) 计算机断层扫描 (CT) 和磁共振成像。患者平均年龄为59.73±8.43岁，其中103名患者为男性。 OSTSL 是根据 3D CT 结果确定的。分析了 OSTSL 与年龄、性别和 RCT 大小之间的相关性。测量肩胛上孔的水平和垂直直径、面积和周长。利用磁共振成像结果计算出的占位比来评估冈上肌萎缩情况。结果在213例RCT患者中，22例（10.3%）患有OSTSL。男性中 OSTSL 的发生率为 15.5%（103 人中的 16 人），高于女性 (P= .016)。 OSTSL 的发生率随着年龄的增长而增加 (P= .003)。 RCT 规模与 OSTSL 的患病率不相关。随着肩胛上孔水平直径和周长的增加，肌肉萎缩逐渐进展（分别为P= .001和P= .046）。结论RCT患者中10例患有OSTSL；男性中 OSTSL 的发生率较高，并且随着年龄的增长而增加。对于准备接受关节镜上横韧带切除术的 RCT 患者，术前通过 3D CT 识别 OSTSL 将有助于切除。
BackgroundThe prevalence of ossified superior transverse scapular ligaments (OSTSLs) in rotator cuff tears (RCTs) has not yet been determined. The purposes of this study were to evaluate the prevalence of OSTSLs in RCTs and to investigate the correlation between OSTSL morphology and supraspinatus muscle atrophy.MethodsWe analyzed a total of 213 patients with RCTs for whom 3-dimensional (3D) computed tomography (CT) and magnetic resonance imaging were performed prior to arthroscopic procedures. The mean age of the patients was 59.73 ± 8.43 years, and 103 patients were men. OSTSLs were identified based on 3D CT findings. The correlations between OSTSLs and age, sex, and RCT size were analyzed. The horizontal and vertical diameters, area, and circumference of the suprascapular foramen were measured. By use of the occupation ratio calculated from magnetic resonance imaging results, supraspinatus muscle atrophy was evaluated.ResultsOf 213 patients with RCTs, 22 (10.3%) had OSTSLs. OSTSLs were found at a rate of 15.5% (16 of 103) in men, higher than that in women (P= .016). The rate of OSTSLs increased with age (P= .003). RCT size was not correlated with the prevalence of OSTSLs. As the horizontal diameter and circumference of the suprascapular foramen increased, muscle atrophy progressed (P= .001 andP= .046, respectively).ConclusionOne of ten patients with RCTs had OSTSLs; the rate of OSTSLs was higher among men and increased with age. For patients with RCTs preparing to undergo arthroscopic superior transverse ligament resection, preoperatively identifying OSTSLs through 3D CT would be useful for the resection.
