INTRODUCTION
We conducted a study to elucidate the correlation between the anatomy of the shoulder joint with the development of rotator cuff tear (RCT) and glenohumeral osteoarthritis (GHOA) by using acromioglenoid angle (AGA).
MATERIALS AND METHODS
The AGA is a new measured angle formed between the line from midglenoid to lateral end of the acromion with the line parallel to the glenoid surface. The AGA was measured in a group of 85 shoulders with RCT, 49 with GHOA and 103 non-RCT/GHOA control shoulders. The AGA was compared with other radiological parameters, such as, the critical shoulder angle (CSA), the acromion index (AI) and the acromiohumeral interval (AHI). Correlational and regression analysis were performed using SPSS 20.
RESULTS
The mean AGA was 50.9° (45.2-56.5°) in the control group, 53.3° (47.6-59.1°) in RCT group and 45.5° (37.7-53.2°) in OA group. Among patients with AGA > 51.5°, 61% were in the RCT group and among patients with AGA < 44.5°, 56% were in OA group. Pearson correlation analysis had shown significant correlation between AGA and CSA ( r = 0.925, p < 0.001). It was also significant of AHI in RCT group with mean 6.6 mm (4.7-8.5 mm) and significant AI in OA group with mean 0.68 (0.57-0.78) with p value < 0.001 respectively.
CONCLUSION
The AGA method of measurement is an excellent predictive parameter for diagnosing RCT and GHOA.
引言
我们开展了一项研究，通过使用肩峰盂角（AGA）来阐明肩关节解剖结构与肩袖撕裂（RCT）及盂肱关节骨关节炎（GHOA）发展之间的相关性。
材料与方法
AGA是一个新测量的角度，由从盂中点至肩峰外侧端的连线与平行于关节盂表面的连线所形成。在一组85例患有RCT的肩部、49例患有GHOA的肩部以及103例非RCT/GHOA对照肩部中测量了AGA。将AGA与其他放射学参数进行比较，如临界肩角（CSA）、肩峰指数（AI）和肩峰肱骨头间距（AHI）。使用SPSS 20进行相关性和回归分析。
结果
对照组的平均AGA为50.9°（45.2 - 56.5°），RCT组为53.3°（47.6 - 59.1°），OA组为45.5°（37.7 - 53.2°）。在AGA > 51.5°的患者中，61%在RCT组；在AGA < 44.5°的患者中，56%在OA组。Pearson相关性分析显示AGA与CSA之间存在显著相关性（r = 0.925，p < 0.001）。RCT组中AHI也具有显著性，平均为6.6 mm（4.7 - 8.5 mm），OA组中AI具有显著性，平均为0.68（0.57 - 0.78），p值均< 0.001。
结论
AGA测量方法是诊断RCT和GHOA的一个优秀预测参数。
