The function of the coracoacromial ligament was investigated in 8 dissecting-room scapulae. Strain gauges were attached around the coracoid process and the acromion, and tension (50 or 100 N) applied through the remaining muscle stumps. The results showed that, after division of the ligament, significantly more distortion could be measured in the acromion than in the coracoid process, which suggests that the 'stay' effect of the coracoacromial ligament is stronger for the former. Since the degree of distortion is largely dependent on the direction of pull, the ligament is interpreted as a dynamic brace between the two processes of the scapula.
在8具解剖室肩胛标本上对喙肩韧带的功能进行了研究。应变片附着于喙突和肩峰周围，并通过剩余的肌肉残端施加50或100牛的张力。结果显示，切断韧带后，肩峰处测得的变形明显多于喙突处，这表明喙肩韧带对肩峰的“支撑”作用更强。由于变形程度很大程度上取决于牵拉方向，因此该韧带被解释为肩胛骨两个突起之间的动态支撑结构。
