A dissection-based study of 10 embalmed human cadavers.
The purpose of this study was to describe the sinuvertebral nerves at the lumbar level and to discuss their possible clinical significance.
Discogenic low-back pain is mediated by the sinuvertebral nerves. However, the detailed descriptions of the sinuvertebral nerves at the lumbar level are lacking.
One hundred L1-L5 intervertebral foramina from 10 embalmed cadavers were studied. The presence of the sinuvertebral nerves was noted. The quantity, origin, pathway, innervation range, and spatial orientations of the sinuvertebral nerves in the L1-L5 intervertebral foramina were examined.
A total of 450 sinuvertebral nerves were identified in the 100 lumbar intervertebral foramina; sinuvertebral nerves were observed in 100.00% of the intervertebral foramina. The sinuvertebral nerves were routinely divided into the following two types: the sinuvertebral nerve deputy branch and sinuvertebral nerve main trunk. Three hundred twelve sinuvertebral nerve deputy branches were found; on average, there were approximately 3.12 (range, 1-8) branches in each intervertebral foramen. One hundred thirty-eight sinuvertebral nerve main trunks were found, and sinuvertebral nerve main trunks were observed in 97.00% of the intervertebral foramina. The initial portion of the sinuvertebral nerve was located along the posterior-lateral edge of the disc to the spinal canal. Sixty-one (44.20%) sinuvertebral nerve main trunks originated from the starting point of the gray ramus communicans of the nerve root; 77 (55.80%) sinuvertebral nerve main trunks originated from the anterior surface of the spinal ganglia of the nerve root.
This is a systematic anatomy study that describes the sinuvertebral nerve at the lumbar level and may be of clinical importance to spinal surgeons. A comprehensive understanding of the distribution of sinuvertebral nerves may lead to significant benefits for patients undergoing percutaneous endoscopic treatment for discogenic low-back pain.
10 具防腐处理的人体尸体解剖学研究。
本研究旨在描述腰椎水平的脊神经节支神经，并探讨其可能的临床意义。
椎间盘源性腰痛是由脊神经节支神经介导的。然而，对于腰椎水平的脊神经节支神经的详细描述尚缺乏。
研究了 10 具防腐处理的尸体的 L1-L5 椎间孔，记录脊神经节支神经的存在情况。检查 L1-L5 椎间孔中脊神经节支神经的数量、起源、路径、支配范围和空间方向。
在 100 个腰椎椎间孔中，共发现 450 条脊神经节支神经；椎间孔中观察到脊神经节支神经的比例为 100.00%。脊神经节支神经通常分为以下两种类型：脊神经节支神经副支和脊神经节支神经主干。发现 312 条脊神经节支神经副支，每个椎间孔平均约有 3.12（范围为 1-8）条分支。发现 138 条脊神经节支神经主干，椎间孔中观察到脊神经节支神经主干的比例为 97.00%。脊神经节支神经的起始部分位于椎间盘的后外侧缘到椎管。61（44.20%）条脊神经节支神经主干起源于神经根灰交通支的起始点；77（55.80%）条脊神经节支神经主干起源于神经根脊神经节的前表面。
这是一项对腰椎脊神经节支神经进行系统解剖学研究的文章，可能对脊柱外科医生具有临床意义。对脊神经节支神经分布的全面了解可能会使接受经皮内镜治疗椎间盘源性腰痛的患者受益。
