肩峰及喙肩韧带的测量及其临床意义

A study clinical significance about measurement of the acromion and the coracoacromial ligament

目的通过测量成人肩峰的长度、宽度和厚度以及喙肩韧带在肩峰止点处的宽度和厚度,为临床应用提供形态学基础。方法选取36个新鲜成人冷冻肩关节标本,分别进行CT扫描,并将扫描数据导入Mimics15.0软件中,重建肩胛骨,使用软件自带工具测量肩峰的长度、宽度和厚度。然后解剖喙肩韧带,用游标卡尺测量其在肩峰止点处的宽度和厚度。结果肩峰的长度为(46.27±2.88)mm,宽度为(25.71±1.52)mm,厚度为(8.10±1.14)mm;喙肩韧带在肩峰止点处的宽度为(14.27±1.19)mm,厚度为(4.05±0.38)mm。结论喙肩韧带和肩峰的解剖学数据,可以为肩关节疾病的临床诊疗提供帮助。

Objective To measure the anatomical parameters of acromion andcoracoacromial ligament at the side of acromion and provide the morphological data. Methods 36 fresh frozen adult shoulder specimens were used. All specimens were scanned by MSCT;mimics15.0 was adopted for analyzing these data and reconstructing the scapula. In 3D reconstruction software, the length of the acromion, width and thickness of acromion were measured. Then dissection of thecoracoacromial ligament was performed. Data of coracoacromial ligament at attachment point on acromion were measured using vernier caliper. Results The length of the acromion is （46.27 ± 2.88） mm,the width is （25.71 ± 1.52） mm, and thickness is （8.10 ± 1.14） mm;The width of the coracoacromial ligament at the attachment point of acromion is （14.27±1.19） mm, thickness is （4.05 ± 0.38） mm. Conclusions Understanding of the anatomy of coracoacromial arch and acromion can provide facilitate diagnosis and treatment of shoulder joint disease.
