Purpose Glenoid bone stock and morphology and rotator cuff muscle quality and tendon integrity affect the outcome of total shoulder arthroplasty. We hypothesized that glenoid bone loss correlates with rotator cuff muscle fatty infiltration (FI), tendinopathy, and atrophy.Design Forty-three 3-D CT scans and MRIs of 43 patients (mean age 62 years; SD 13 years; range 22-77 years) referred for primary shoulder pain were evaluated. Measurements of glenoid bone stock, version, and posterior humeral subluxation index (HSI) were assessed on an axial CT image reconstructed in the true scapular plane. Measurements utilized the Friedman line to approximate the pre-pathologic surface. Glenoid morphology was assigned by modified Walch classification. Rotator cuff FI, atrophy, and tendon integrity were assessed on corresponding MRIs.Results There was a very strong negative correlation between increasing glenoid version and HSI (r = - 0.908; p < 0.0001). There was a moderately negative correlation between anterior bone loss and HSI (r = - 0.562; p < 0.0001) and a moderately positive correlation between posterior bone loss and HSI (r = 0.555; p < 0.0001). Subscapularis muscle FI correlated moderately with increased anterior and central bone loss and increased humeral head medialization (r = 0.512, p = 0.0294; r = 0.479, p = 0.033; r = 0.494, p = 0.0294, respectively). Inter-observer reliability (intra-class correlation coefficient [ICC] and kappa) was good to excellent for all measurements and grading.Conclusion Glenoid anteversion and anterior and posterior bone loss are associated with varying HSI. Subscapularis muscle FI, not tendon integrity, correlates to anterior and central glenoid erosion. The study adds evidence that neither rotator cuff tendinopathy nor muscle atrophy exhibits a significant relationship to HSI.

校正至:关节盂骨储备和关节盂版本的定性和定量分析:肩阅读器分析以及肩关节骨关节炎患者肩袖肌腱病变和萎缩的相关性。

目的关节盂的骨质,形态和肩袖肌的质量以及肌腱的完整性会影响全肩关节置换的结果。我们假设关节盂骨丢失与肩袖脂肪浸润(FI),肌腱病和萎缩有关。设计43例患者的43个3-D CT扫描和MRI(平均年龄62岁; SD 13岁;范围22-77)年)被评估为原发性肩痛。在真实的肩plane骨平面中重建的轴向CT图像上评估了盂盂骨储备,版本和肱骨后半脱位指数(HSI)的测量。测量利用弗里德曼线来近似病理前表面。肾盂形态由改良的Walch分类指定。在相应的MRI上评估肩袖FI,萎缩和肌腱完整性。结果关节盂变高和HSI之间存在非常强的负相关性(r =-0.908; p <0.0001)。前骨丢失和HSI之间呈中等程度的负相关(r =-0.562; p <0.0001),后骨丢失和HSI之间呈中等程度的正相关(r = 0.555; p <0.0001)。肩s下肌FI与增加的前骨和中骨丢失和增加的肱骨头中度适度相关(r = 0.512,p = 0.0294; r = 0.479,p = 0.033; r = 0.494,p = 0.0294)。观察者之间的可靠性(类内相关系数[ICC]和kappa)在所有测量和分级中均表现出色至极好。结论关节盂前倾和前,后骨丢失与HSI的变化有关。肩s下肌FI,不是腱完整,与前,中关节盂糜烂相关。该研究增加了证据,既没有肩袖肌腱病也没有肌肉萎缩与HSI表现出显着关系。
