The dorsal scapular nerve and long thoracic nerve of 10 cadavers (20 sides) and 36 patients with dorsal scapular nerve compression were studied anatomically. The origin of the dorsal scapular nerve of a section frequently shared a common trunk with the long thoracic nerve, and went through the scalenus medius anterointernally and posterolaterally with the presence of some tendinous tissues. Leaving the long thoracic nerve, it might give branches to the shoulder and the subaxillary region and finally have the branches join the long thoracic nerve again. The compression of the section near the origin caused discomfort and sourness of the neck, shoulder and back region. Clinically, the severance of the scalenus anterior and medius ameliorated or relieved the compression of the dorsal scapular nerve. Complete decompression required cutting of the scalenus medius and its tendinous tissue superficial to the dorsal scapular nerve. Among 24 sides of 22 patients undergoing surgery, the symptoms of 20 sides of 19 patients were completely or partially relieved.
对10具尸体(20侧)的肩胛背神经和胸长神经以及36例肩胛背神经卡压患者进行了解剖学研究。一部分肩胛背神经的起始部常与胸长神经共干,经中斜角肌前内侧和后外侧并伴有一些腱性组织穿出。离开胸长神经后,它可能发出分支至肩部和腋下区域,最终分支又再次汇入胸长神经。在起始部附近的卡压会引起颈、肩和背部区域的不适与酸痛。临床上,切断前、中斜角肌可改善或缓解肩胛背神经的卡压。完全减压需要切断中斜角肌及其在肩胛背神经表面的腱性组织。在接受手术的22例患者的24侧中,19例患者的20侧症状得到完全或部分缓解。
