Title:Vulnerability of long thoracic nerve: an anatomic study

标题：胸长神经易损性解剖研究

Content/内容：

1) The anatomic course of 40 long thoracic nerves was studied in relation to anatomic landmarks and reference lines, that is, the axillary lines and first 2 ribs.

研究40个标本的胸长神经解剖路径及其与解剖标志、参照线（腋线与第一、二肋骨）的关系。

2) After its supraclavicular course, the nerve passes beneath the clavicle within the axillary sheath and then emerges from the axillary sheath.

经锁骨上运行后，胸长神经在腋鞘内穿行于锁骨下出腋鞘。

3) As it passes inferiorly and posteriorly from the point of emergence to the posterior angle of the second rib ( that is, the attachments of serratus anterior muscle), it makes a posterior angle of 30.7 degrees on average, relative to the anterior axillary line.

自后下穿出至第二肋后骨角（即前踞肌附着）时，与腋前线构成后角（平均30.7°）。

4) It then continues to descend inferiorly between the middle and posterior axillary lines.

然后继续下降于腋中与腋后线之间。

5) When the arm is raised, the axillary neurovascular bundle moves superiorly with the movements of the arm.

当手臂上抬时，腋神经血管束随着手臂运动而上移。

6) The long thoracic nerve is angulated and stretched at the point it passes out of the axillary sheath.

胸长神经在出腋鞘处成角度牵拉。
