The author conducted a study to investigate the anatomy of the intraforaminal ligaments of the thoracic and lumbar nerve roots and describe their anatomical relationships and functional properties. This anatomical study performed on the intervertebral foramina, intraforaminal ligaments, transforaminal ligaments, and nerve roots of the thoracic and lumbar spine was performed in human cadavers.
The foraminal anatomy was studied in 11 whole cadavers (5 females, 6 males) previously prepared with formaldehyde, whose ages at the time of death ranged from 16 to 71 years. The thoracic and lumbar spinal columns were separated from the cervical and sacral segments en bloc using an electric band saw. The paraspinal muscles and their attachments were removed by sharp and meticulous dissection, and the thoracic and lumbar intervertebral foramina were examined under a surgical microscope. The intervertebral foraminal ligaments and nerve roots were exposed. The foraminal contents were identified and studied in detail. The intraforaminal ligaments were stained using H & E to determine ligamentous fiber.
Intraforaminal ligaments connect the periosteum and transforaminal ligaments to the nerve root sleeves and vessels within the fatty areolar tissue. Histologically, the ligamentous attachment of the nerve roots within the foramina consists of adipose and connective tissue.
The nerve roots are surrounded by intraforaminal ligaments, which may act in conjunction with the dura and periosteum to protect the nerve roots mechanically.
作者进行了一项研究，旨在调查胸腰椎神经根椎间孔内韧带的解剖结构，并描述其解剖关系和功能特性。这项在胸腰椎椎间孔、椎间孔内韧带、经椎间孔韧带和神经根上进行的解剖学研究是在人类尸体上进行的。
在 11 具经甲醛预处理的完整尸体（5 名女性，6 名男性）中进行了椎间孔解剖学研究，这些尸体的死亡年龄在 16 岁至 71 岁之间。使用电动带锯将颈段和骶段与胸腰椎脊柱整块分离。通过锐性和精细的解剖去除椎旁肌肉及其附着处，并在手术显微镜下检查胸腰椎椎间孔。暴露椎间孔内韧带和神经根。详细识别和研究椎间孔内容物。使用 H & E 对椎间孔内韧带进行染色，以确定韧带纤维。
椎间孔内韧带将骨膜和经椎间孔韧带与脂肪疏松组织内的神经根袖套和血管相连。组织学上，椎间孔内神经根的韧带附着由脂肪和结缔组织组成。
神经根被椎间孔内韧带环绕，这些韧带可能与硬脑膜和骨膜一起起到机械保护神经根的作用。
