Examination was performed on 100 cadaveric specimens to demonstrate the anatomy of the coracoacromial (C-A) ligament. In a substantial number (34 specimens), the bipartite nature of the ligament and the breadth of its insertions were considerably more pronounced than usually perceived through the arthroscope. Supplementing the cadaveric material, 300 dry bone scapulae were examined from museum specimens of older persons. These demonstrated various degrees of transformation of the C-A ligament into bone (enthesopathy) at its acromial insertion. Variations in the patterns of these enthesopathic transformations corresponded to variations in the patterns seen in the cadaveric material. This variability is of practical importance in a variety of operative procedures. Additionally, the relationship between the acromial insertion of the C-A ligament and the overlying deltoid muscle was examined. An understanding of this relationship is crucial in avoiding complications when operating in this area.
对100个尸体标本进行检查以展示喙肩韧带（C-A韧带）的解剖结构。在相当数量（34个标本）中，该韧带的二分性质及其附着的宽度比通过关节镜通常所观察到的更为明显。作为尸体材料的补充，从老年人的博物馆标本中检查了300块干燥的肩胛骨。这些标本显示出C-A韧带在其肩峰附着处有不同程度的韧带骨化（起止点病）。这些起止点病性改变的模式变化与尸体材料中所见模式的变化相对应。这种变异性在各种手术操作中具有实际重要性。此外，还检查了C-A韧带肩峰附着处与上方三角肌之间的关系。了解这种关系对于在该区域手术时避免并发症至关重要。
