The histologic characteristics of the deltoid muscle attachment to nine cadaveric acromia were studied using light microscopy. The deltoid muscle attaches to the anterior and lateral acromion primarily by direct tendinous attachment. The muscle attaches to the dorsal side of the acromion by periosteal fiber attachment. In the specimens studied, a hypothetical acromioplasty of 4 mm would release, on average, 41% of the direct fiber attachment, and a 6-mm acromioplasty would release 69% for all zones examined histologically. The functional and clinical effects of these findings are not known, but the deltoid muscle would be released by arthroscopic acromioplasty in areas where bone is removed.
利用光学显微镜研究了9具尸体肩峰上三角肌附着处的组织学特征。三角肌主要通过直接腱性附着附着于肩峰的前侧和外侧。肌肉通过骨膜纤维附着附着于肩峰的背侧。在所研究的标本中，假设进行4毫米的肩峰成形术，平均会松解41%的直接纤维附着，而6毫米的肩峰成形术在组织学检查的所有区域会松解69%。这些发现的功能和临床影响尚不清楚，但在去除骨质的区域，关节镜下肩峰成形术会松解三角肌。
