基于MRI喙锁韧带的解剖学参数分析

目的　研究喙锁韧带的形态特点及其对骨隧道建立的指导意义。 方法　收集2017年1月1日至2020年1月1日480例肩胛骨MRI扫描数据，在斜冠状位和斜矢状位图像上测量4个角度和7个距离，并采用SPSS 20.0进行分析。 结果　在斜冠状位图像上，肩锁关节中点到锁骨钻孔点的距离男性平均值大于女性，有统计学差异（P<0.05）；在斜矢状位图像上，男性的喙锁韧带锁骨附着处中心到喙突附着处中心的距离，喙锁韧带锁骨附着处中心到喙突尖端的距离，锁骨上表面的中点到喙突下表面最远端的距离，喙锁韧带锁骨附着处直径平均值均大于女性，差异有统计学意义（P<0.05）。 结论　这些解剖参数能够完整地描述喙锁韧带的解剖学特征，指导骨隧道的准确建立，利于对肩锁关节脱位的个体化治疗。

Analysis on the anatomical parameters of coracoclavicular ligament based on MRI

Objective 　To study the morphological characteristics of the coracoclavicular ligament and its guiding significance for transosseous tunnels construction.　Methods　The MRI scan data of 480 scapula patients were collected from January 1, 2017 to January 1, 2020. Four angles and seven distances from 480 MRI scan were defined and measured in images of the coronal and sagittal plane. All data were analyzed by SPSS 20.0. Results In the coronal plane, the average distance from the midpoint of acromioclavicular joint to the insertion at the clavicle was greater in males than in females, with statistical difference (P<0.05). In the sagittal plane, in addition to the diameter of insertion at the coracoid process, the distance from the insertion at the clavicle to the insertion at the coracoid process, the distance from the tip of the coracoid process to the insertion at the coracoid process, the distance from the supraclavicular plane of the clavicle to the subcoracoid plane of the coracoid process, the diameter of insertion at the clavicle in males were greater than those in females, with statistical difference (P<0.05).　Conclusions　These anatomical parameters could completely describe the anatomical characteristics of coracoclavicular ligament, which are beneficial for the construction of coracoclavicular ligament to create transosseous tunnels accurately and individualized treatment of acromioclavicular dislocation.
