摘要
目的 :观察C7横突前结节与第 1肋颈间异常韧带与C8颈神经前支的关系 ,为临床诊治提供解剖学基础。方法 :3 2具成人尸体标本 ,解剖观察C7横突前结节与第 1肋颈间异常韧带及其与第 1肋颈上面及中小斜角肌内缘所围成的三角形结构与C8颈神经前支的关系。结果 :C7横突前结节与第 1肋颈间异常韧带的出现率为 15 .63 % ,其长度为 ( 0 .98± 0 .18)cm ,宽度为 ( 0 .3 9± 0 .11)cm ,厚度为 ( 0 .0 6±0 .0 2 )cm。C8颈神经前支出椎间孔后经此异常韧带的深面进入三角形结构内 ,然后跨过中小斜角肌的内缘进入斜角肌间隙。结论 :C8颈神经前支经过此三角形结构时周围结构的压迫是导致胸廓出口综合征的原因之一。
Objective: To investigate the relationship between the anterior branches of C 8 nerves and the abnormal ligaments located between the anterior tubercles of C 7 vertebrae and the costal necks of the first ribs, and provide anatomical basis for clinical therapy. Methods: 32 adult cadavers were dissected and observed. The characteristics of the abnormal ligaments between the anterior tubercles of C 7 vertebrae and the costal necks of the first ribs, and the relationship between the anterior branches of C 8 nerves and the triangular structure composed by the lateral borders of the abnormal ligaments, the costal necks of the first ribs and the medial border of the scalene were investigated. Results: The occurrence rate of the abnormal ligaments was 15.63%. Their length ?width and thickness were 0.98±0.18 cm?0.39±0.11 cm?0.06± 0.02 cm respectively. After going through the intervertebral foramina, the anterior branches of C 8 nerves entered the triangular structure through the posterior surface of abnormal ligaments. And then they crossed the medial borders of the scalene medius?scalene mininus and entered the scalene fissure. Conclusions: Oppressed by the neighbor structure of the anterior branches of C 8 nerves when they went through the triangular structure was one of the causes of the thoracic outlet syndrome.
