摘要:


文题释义:

肩峰悬垂:三维空间中肩峰最外侧点到关节盂下盂圆最佳拟合平面的距离,可以更加直观反映肩峰的外侧延伸和覆盖,相对于X射线片及MRI图像上测量的临界肩关节角,肩峰悬垂这一概念避免了冠状位上关节盂倾斜对于测量的影响。
肩峰覆盖角:是肩峰前端平面和肩峰后端平面之间的夹角,有研究基于MRI图像测量此角度,分析此角度与肩袖撕裂有无联系,它可以反映肩峰前后侧对于肩袖组织的覆盖程度,是肩峰解剖结构的体现,近来有研究围绕肩峰覆盖角与肩袖撕裂之间的关系而展开。


背景:肩峰形态变化是退变性肩袖撕裂的最重要外在因素,关于肩峰形态及肩峰覆盖的相关研究一直在持续进行。 

目的:观察肩峰在三维空间中对于肩袖组织的覆盖,测量冠状位及矢状位参数,探究肩峰悬垂、肩盂角及肩峰覆盖角与退变性肩袖全层撕裂的关系。
方法:回顾性收集2022年1月至2023年6月于徐州医科大学附属医院经肩关节镜手术或MRI检查确诊为肩袖全层撕裂的患者56例为撕裂组,同时纳入非肩袖撕裂患者48例为对照组。收集两组患者的临床资料和胸部CT资料,使用Mimics软件重建患者肩胛骨,在3-matic软件内测量两组患者的肩峰悬垂、肩盂角和肩峰覆盖角,比较两组患者测量参数之间的差异,并对测量参数进行二元Logistic回归分析及受试者工作特征曲线分析,评估测量参数预测肩袖撕裂的能力,一般参数的受试者工作特征曲线下面积大于0.8则认为该参数具有较好的诊断价值。

结果与结论:①肩袖撕裂组患者的肩峰悬垂均值大于对照组(P < 0.001),肩峰覆盖角均值也大于对照组(P < 0.001);两组患者的肩盂角均值比较差异无显著性意义(P > 0.05);②二元Logistic回归分析显示肩峰悬垂与肩峰覆盖角均是肩袖撕裂的危险因素(P < 0.05);③受试者工作特征曲线分析提示肩峰悬垂与肩峰覆盖角的曲线下面积分别为0.725和0.865,最佳截断值分别为36.15 mm和60.65°;④结果显示,肩袖撕裂患者的肩峰悬垂和肩峰覆盖角大于非肩袖撕裂患者,它们均与退变性肩袖全层撕裂有关,可以用来预测肩袖撕裂,并且肩峰覆盖角的预测效能更高。

Abstract: BACKGROUND: Acromion morphology is the most important external factor of degenerative rotator cuff tear, and studies on acromion morphology and acromion coverage have been continuing. 
OBJECTIVE: To investigate the coverage of acromion on rotator cuff tissue in three-dimensional space, measure coronal and sagittal parameters, and explore the relationship of acromial overhang, acromioglenoid angle and acromial coverage angle with degenerative full-thickness rotator cuff tears.
METHODS: A total of 56 patients diagnosed with full-thickness rotator cuff tears by shoulder arthroscopic surgery or MRI in the Affiliated Hospital of Xuzhou Medical University from January 2022 to June 2023 were retrospectively collected as the tear group, while 48 patients with non-rotator cuff tear were included as the control group. Clinical data and chest CT data of the patients of the two groups were collected, and the shoulder blades of the patients were reconstructed using Mimics software. Acromial overhang, acromioglenoid angle and acromial coverage angle were measured in 3-matic software. The differences between the measurement parameters were compared between the two groups. Binary Logistic regression analysis and receiver operating characteristic curve analysis were performed to evaluate the ability of the measurement parameters to predict rotator cuff tear. It is generally believed that the parameter had good diagnostic value when the area under the receiver operating characteristic curve was greater than 0.8.
RESULTS AND CONCLUSION: (1) The mean acromial overhang in patients with rotator cuff tears was greater than that in controls (P < 0.001). The mean acromial coverage angle was also greater in patients with rotator cuff tears than in controls (P < 0.001). There was no significant difference in the acromioglenoid angle between the two groups (P > 0.05). (2) Binary Logistic regression analysis showed that acromial overhang and acromial coverage angle were both risk factors for rotator cuff tear (P < 0.05). (3) Receiver operating characteristic curve analysis indicated that the areas under the curve of acromial overhang and acromial coverage angle were 0.725 and 0.865, respectively, and the optimal cutoff values were 36.15 mm and 60.65°. (4) The results showed that the acromial overhang and acromial coverage angle were greater in patients with rotator cuff tears than in patients without rotator cuff tears. Both were associated with degenerative full-thickness rotator cuff tears, and they could be used to predict rotator cuff tears, and the acromial coverage angle was more effective in predicting rotator cuff tears.

Key words: rotator cuff tear, acromial overhang, acromioglenoid angle, acromial coverage angle, three-dimensional reconstruction, acromion
