Cadaveric anatomic dissections of 50 shoulders have been done with measurement and histologic analysis of the coracoacromial ligament. In subjects older than 50 years of age the coracoacromial ligament does not have a constant form. Three main types were identified: quadrangular, Y-shaped, and a broad band. A previously unreported type of coracoacromial ligament the multiple banded ligament, was found. It had the largest coracoid attachment. This ligament was similar to the Y form but with an additional band extending inferiorly and medially toward the base of the coracoid. Histologic analysis indicates the multiple banded type could be more common than this study suggests.
对50个肩部进行了尸体解剖，并对喙肩韧带进行了测量和组织学分析。在年龄超过50岁的受试者中，喙肩韧带没有恒定的形态。确定了三种主要类型：四边形、Y形和宽带状。发现了一种以前未报道过的喙肩韧带类型——多束韧带。它在喙突上的附着面积最大。这种韧带类似于Y形，但有一条额外的束带向下内侧延伸至喙突基部。组织学分析表明，多束韧带类型可能比本研究显示的更为常见。
