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