Title:Vulnerability of long thoracic nerve: an anatomic study

標題：胸長神經易損性解剖研究

Content/內容：

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個標本的胸長神經解剖路徑及其與解剖標志、參照線（腋線與第一、二肋骨）的關系。

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

經鎖骨上運行后，胸長神經在腋鞘內穿行于鎖骨下出腋鞘。

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（即前踞肌附著）時，與腋前線構成后角（平均30.7°）。

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

然后繼續(xù)下降于腋中與腋后線之間。

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

當手臂上抬時，腋神經血管束隨著手臂運動而上移。

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

胸長神經在出腋鞘處成角度牽拉。
