STRUCTURAL ORGANIZATION AND MORPHOMETRIC CHARACTERISTICS OF INTERVERTEBRAL CHANNELS OF THE CERVICAL SPINE

The objective of research was to study topographic-anatomical characteristics of the intervertebral canal. A total of 37 anatomical preparations were studied, which included 185 intervertebral canals of cervical spine section compexes of people who died at the age 58-78 years. A histological study of 32 preparations of ligament structures was performed. 5 pairs of true cervical intervertebral canals were detected in C-C segments. Average parameters of intervertebral channels were as follows: length - 1.46-2.0 mm, external aperture - 0.8-1.4 mm, internal aperture - 0.4-0.8 mm. Histological study confirmed that the examined structures were ligaments, their diameter varied from 0.1 to 0.3 mm, and their length varied from 0.4 to 0.6 mm. Intervertebral canals can be divided into three groups: canals with clearly identified true ligaments (46%); canals with additional false ligaments (fibrotic bands) which compress the spinal nerve (43%); and canals without ligaments but with bone and fibrous outgrowths compressing the spinal nerve (11%).
