本文对中国成年人尸体40具(80侧)进行了腰神经后内侧支伴同血管经过后内侧支骨纤维管以及与腰神经后外侧支之间吻合情况的观察;测量了腰神经后支的长度、直径以及腰神经后外侧支、后内侧支的直径;同时还测量了腰神经后支分后内、后外侧支与横突根上缘间的距离。作者根据上述观察和测量提出腰神经后支及其分支有三处最易遭受卡压;一是神经出腰神经后支骨纤维管外口处;二是神经进入腰神经后内侧支骨纤维管入口处;三是神经行于腰神经后内侧支骨纤维管内骨嵴的顶坡处。并且还阐明了椎管外骨纤维管的解剖与神经之间的关系。
In this paper, we observed the anastomosis between the posterior medial branch of the lumbar nerve and the medial branch of the spinal canal and the posterior lateral branch of the lumbar nerve in 40 adult (80 sides) Chinese adults. The length of the posterior branch of the lumbar nerve , Diameter and the diameter of posterior lateral branch and posterior medial branch of lumbar nerve. The distance between the posterior lateral branch and the superior margin of transverse root was also measured. According to the above observation and measurement, the authors suggest that the posterior branch of the lumbar nerve and its branches are the three most vulnerable to compression; one is the posterior branch of the nerve fiber of the lumbar nerve; the other is the entry of the nerve into the medial branch of the lumbar nerve fiber branch Department; Third, the line of nerves in the lumbar nerve fibers inside the medial branch of the crest of the ridge. It also clarifies the relationship between the anatomy and nerves of the spinal canal.
