摘要:

文题释义:

肩袖:由起自肩胛骨的冈上肌、冈下肌、肩胛下肌、小圆肌包绕肱骨头形成一个袖套样结构。外伤和退行性变时,组成肩袖的肌腱会发生水肿、炎性病变甚至撕裂,是引起肩部疼痛和功能障碍的重要因素。

临界肩关节角肩关节X射线片上肩胛盂上下骨边缘的连线与来自肩峰外下侧边缘的另一条线在肩胛盂下缘构成的夹角。临界肩关节角近年来成为研究的热点。

背景:肩胛骨的解剖结构被发现与肩袖撕裂的发生有关,临界肩关节角可以反映肩胛骨的个体解剖学差异,近年来有研究发现临界肩关节角为肩袖撕裂的一项危险因素,但其在国人中对预测肩袖撕裂的诊断价值仍需进一步研究。

目的分析临界肩关节角(CSA)在国人中是否也是肩袖撕裂的一项危险因素,临界肩关节角与肩峰指数和肩胛盂倾斜度相比较在退行性肩袖撕裂的风险水平。

方法收集20161月至201812月诊断为肩袖撕裂的患者32例作为肩袖撕裂组,其中男17例,女15例,年龄37-75岁,平均(54.7±9.2)岁;同时选取非肩袖撕裂患者34例作为对照组,其中男19例,女15例,年龄35-91岁,平均(53.6±11.8)。分别比较两组肩关节X射线片的临界肩关节角值、肩峰系数值以及关节盂倾角β角,并进行各参数相关性分析以及受试者工作特征曲线(ROC)分析,以确定截断值和曲线下面积。

结果与结论:①肩袖撕裂组的临界肩关节角均值明显大于对照组(37.4° vs. 34.1°,P < 0.001);肩袖撕裂组肩峰系数值也明显大于对照组(0.72 vs. 0.68,P=0.007);但关节盂倾角β角和年龄在两组之间比较差异无统计学意义(P > 0.05);②相关性分析中,各参数中仅有临界肩关节角与肩峰系数呈较高度正相关(r=0.848,P < 0.001),其余各参数两两之间不存在相关关系(P > 0.05);③受试者工作特征曲线(ROC)分析中,临界肩关节角和肩峰系数的曲线下面积分别为0.752和0.663,截止值分别为37.5和0.72。提示:在国人中临界肩关节角可能是退行性肩袖撕裂危险因素,且较肩峰指数有更高的退行性肩袖撕裂风险水平。

Abstract:

BACKGROUND: The anatomical structure of the shoulder blade is related to the occurrence of a rotator cuff tear, and critical shoulder angle (CSA) can reflect the individual anatomical differences of the shoulder blade. In recent years, studies have found that CSA is a risk factor for rotator cuff tear; however, its diagnostic value for rotator cuff tear in Chinese population still needs further research.

OBJECTIVE: To analyze whether CSA is a risk factor for rotator cuff tear in Chinese people, and to explore the risk level of CSA in degenerative rotator cuff tear in comparison with acromion index (AI) and glenoid inclination.

METHODS: Thirty-two patients who had been diagnosed with rotator cuff tear from January 2016 to December 2018 were collected as the tear group, including 17 males and 15 females, aged 37-75 years, with an average age of (54.7±9.2) years. Meanwhile, another 34 patients without rotator cuff tear were selected as the control group, including 19 males and 15 females, aged from 35 to 91 years, with an average (53.6±11.8) years. The CSA, AI and β angle of the glenoid cavity were compared between two groups. Correlation analysis and receiver operating characteristic curve analysis were performed for each parameter to determine the cutoff value and the area under the curve.

RESULTS AND CONCLUSION: The mean CSA and AI of the tear group were significantly higher than those of the control group (37.4° vs. 34.1°, P < 0.001; 0.72 vs. 0.68, P=0.007). However, there was no significant difference between the tear group and the control group in the β angle of the glenoid cavity and age (P > 0.05). In the correlation analysis, only CSA showed a high positive correlation with AI among all parameters (r=0.848, P < 0.001), whereas there was no correlation between the other parameters (P > 0.05). In the receiver operating characteristic curve analysis, the area under the curve of CSA and AI was 0.752 and 0.663, respectively, with cut-off values of 37.5 and 0.72. To conclude, It may be a risk factor of degenerative rotator cuff tear for Chinese people, and it has a higher risk level of degenerative rotator cuff tear than the acromion index.
