This study consists of 3 sections: a descriptive study of the intervertebral foramen by dissection, supplemented by millimetric sections made with the cine-microabrasive apparatus (patented) on 12 specimens frozen with liquid nitrogen; a study of the attachments of the roots made during manipulations testing the resistance to avulsion of the rootlets, the roots, the dural sheath and the fibrous expansions at the periphery of the intervertebral foramen; and a study of the mobility of the roots in the foramina during movements effected within and outside the spine. We concluded that the classical description of an intervertebral foramen as occluded by a taut membrane like a drum-head is false as only perforated expansions attach the root to the foramen. Further, the points for attachment of the roots are the dura mater and the fibrous expansion passing from the foramen to the sheath of the spinal n. Finally, from the aspect of mobility, there are 2 distinct compartments and movements in one are not perceived in the other compartment if the attachments are unbroken. These attachments are a barrier interposed between the two compartments.
通过解剖对椎间孔进行描述性研究，并辅以使用电影微磨蚀装置（专利）对12个用液氮冷冻的标本制作的毫米切片；在测试神经根丝、神经根、硬脊膜鞘和椎间孔周边纤维扩展抗撕脱性的操作过程中，对神经根附着情况的研究；以及在脊柱内外进行运动时，对神经根在椎间孔内活动情况的研究。我们得出结论，将椎间孔经典地描述为被像鼓面一样紧绷的膜封闭是错误的，因为只有穿孔的扩展部分将神经根附着于椎间孔。此外，神经根的附着点是硬脊膜以及从椎间孔通向脊神经鞘的纤维扩展部分。最后，从活动方面来看，存在两个不同的腔室，如果附着部分未断裂，一个腔室内的运动在另一个腔室内是无法察觉的。这些附着部分是介于两个腔室之间的屏障。
