Aim. To prove participation of a soft stroma of intervertebral channels of lumbosacral department of a backbone in development of an ischemia of the bottom departments of a spinal cord on the basis of studying of topographical anatomy of contents of channels at people with various type of a constitution. Material and Methods. Contents of 620 lateral intervertebral channels of lumbar department of a backbone are studied. The material was distributed on groups, depending on constitution type. In preparations taken from people with dolichomorphic structure type have the least sizes (basically width of an aperture), and in preparations taken from people with brachymorphic type of a structure - the sizes the greatest. Results and Discussion. In 54.84% in the field of lateral intervertebral channels of lumbosacral department of a vertebral column are found out - intraforaminal ligaments. 50% - mesomorphic addition type, 26.47% - dolichomorphic and 23.53% - by brachymorphic. Histologically found out formations have copular structure. The copular apparatus reduces free space round the vessels which are passing in the intervertebral channel, in limits from 44.97 to 79.84% that can lead to a compression of the contained intervertebral channel both at a trauma, and at is degenerate-dystrophic diseases of a backbone. The worst conditions for contents of intervertebral channels are framed at people with dolichomorphic type of a structure of a body in the presence of plural intraforaminal ligaments. Conclusions. Such combination based on results of given research, can meet at 25.5% of people with dolichomorphic type of a structure of a body.
