This study is aiming to evaluate some specific anatomic shoulder parameters such as the lateral acromial angle (LAA), acromial index (AI), coracohumeral distance (CHD) and critical shoulder angle (CSA) in rotator cuff tears.
A total of 100 cases consisting of 50 patients with rotator cuff tears and 50 patients without rotator cuff tears, who underwent shoulder MRI (mangnetic resonance imaging) examination in Istanbul Medipol University Orthopedics and Traumatology Department, participated in this study. In this retrospective study, CCA, LAA, AI and CSA were evaluated in MRI in order to shed light on the theories of rotator cuff tears.
There was no significant difference (P ˃ .05) in acromial index and coracohumeral distance in the patient group. Lateral acromial angle and critical shoulder angle were significantly different in the patient group compared to the control group (P < .05). There was a weak negative correlation between CSA and CHD.
In our study, we found that patients with smaller LAA and higher CSA values in MRI images are prone to have rotator cuff tears. Further studies are needed in order to evaluate whether this association has predictive value.
本研究旨在评估肩袖撕裂患者的一些特定解剖学肩部参数，如外侧肩峰角（LAA）、肩峰指数（AI）、肩峰肱骨关节距离（CHD）和临界肩角（CSA）。
本回顾性研究共纳入 100 例患者，其中 50 例为肩袖撕裂患者，50 例为无肩袖撕裂患者，均在伊斯坦布尔 Medipol 大学骨科和创伤科接受了肩部 MRI（磁共振成像）检查。为了探讨肩袖撕裂的理论，我们在 MRI 中评估了 CCA、LAA、AI 和 CSA。
在患者组中，肩峰指数和肩峰肱骨关节距离无显著差异（P>.05）。与对照组相比，患者组的外侧肩峰角和临界肩角有显著差异（P<.05）。CSA 与 CHD 之间存在弱负相关。
在我们的研究中，我们发现 MRI 图像中 LAA 较小和 CSA 值较高的患者更容易发生肩袖撕裂。需要进一步研究以评估这种相关性是否具有预测价值。
