We studied the origin of the anterior deltoid from the lateral third of the clavicle and the leading anterior edge of the acromion in 18 cadaver shoulders by anatomical and histological methods. The main origin of the deltoid was from the superior surface of the anterior acromion, but muscle and tendinous attachments were also seen on the entire anterior surface of the acromion, its anteroinferior surface and on the whole width of the anterior surface of the clavicle. Mock arthroscopic acromioplasty was shown to detach deltoid fibres from the anterior surfaces, leaving the superior attachment in continuity. Potentially, arthroscopic subacromial and clavicular resection can detach deltoid fibres originating from the anterior and anteroinferior surfaces of the acromion and clavicle and thus weaken the anterior deltoid.
我们通过解剖学和组织学方法，对18具尸体肩部三角肌前部从锁骨外侧三分之一和肩峰前缘的起源进行了研究。三角肌的主要起源于肩峰前部的上表面，但在肩峰的整个前表面、其前下表面以及锁骨前表面的整个宽度上也可见肌肉和肌腱附着。模拟关节镜下肩峰成形术显示可从前表面分离三角肌纤维，而上方附着保持连续。关节镜下肩峰下和锁骨切除术可能会分离起源于肩峰和锁骨前表面及前下表面的三角肌纤维，从而削弱三角肌前部。
