Studies were performed using 37 anatomical preparations including 185 intervertebral canals in section complexes of the of the cervical segment of the spines of people dying at age 58–78 years. Histological investigations were performed using 32 preparations of ligamentous structures. Five pairs of true intervertebral canals were identified in segments C2–C7. The mean parameters of intervertebral canals were: length 1.46–2.0 mm; outer opening 0.8–1.4 mm; inner opening 0.4–0.8 mm. Histological studies confirmed data showing that the structures observed were ligaments, with diameters ranging from 0.1 to 0.3 mm and length from 0.4 to 0.6 mm. Intervertebral canals could be divided into three groups: those with clearly defined true ligaments (46%), ligaments with additional false ligaments (fibrotic bands) compressing the spinal nerve (43%), and canals without ligaments but with bony and fibrotic protuberances compressing the spinal nerve (11%).
