To determine the distance between the axillary nerve and the antero-lateral (AL) edge of the acromion, its anatomical variability and relationship to humeral length and body height.
Twenty-two shoulders were dissected. The anterosuperior (AS) approach was used; the deltoid was detached from the acromion and the distance between the AL portion and the axillary nerve was measured and submitted to statistical analysis.
The distance varied from 4.3 to 6.4 cm (average 5.32 ± 0.60 cm). The axillary nerve distance increased as the humeral size (p<0.05) and the height of each cadaver increased. However, the correlation with the specimens height was not significant (p=0.24).
The distance between the acromion and the axillary nerve on the AS approach was 5.32 ± 0.60 cm in both shoulders, and increasing the humeral length there is also an increase in the axillary nerve distance. Level of Evidence IV, Case Series - Anatomic Study.
确定腋神经与肩峰前外侧（AL）边缘之间的距离、其解剖变异性以及与肱骨长度和身高的关系。
解剖22个肩部。采用前上（AS）入路；将三角肌从肩峰分离，测量AL部分与腋神经之间的距离并进行统计分析。
该距离在4.3至6.4厘米之间变化（平均5.32±0.60厘米）。腋神经距离随着肱骨大小（p<0.05）和每个尸体的身高增加而增加。然而，与标本身高的相关性不显著（p=0.24）。
在AS入路中，两侧肩部肩峰与腋神经之间的距离为5.32±0.60厘米，肱骨长度增加时腋神经距离也增加。证据等级IV，病例系列 - 解剖学研究。
