ABSTRACT

To determine the central stenosis of the lumbar spinal canal, the CT method was used to study the lumbar spinal segment in 35 patients without pathology of the lumbar spine (control group) and 40 patients with degenerative-dystrophic diseases of the lumbar spine. They measured the mid-sagittal and frontal dimensions of the lumbar spinal canal, the vertical size of the intervertebral disc in the frontal and lateral projections and found that the dimensions of the lumbar spinal canal in the control group in the caudal direction expand, the intervertebral disc thickens. Comparing the pathological values of the parameters of the lumbar spine with the norm, the following results were obtained: the mid-sagittal and frontal dimensions of the spinal canal, the vertical size of the intervertebral disc in the affected vertebrae (L3; L4; L5; L3-L4; L4-L5; L5-S1) reliably narrowed or shortened. Pathology is more pronounced in the caudal regions. Thus, with the help of CT, it is possible with high accuracy to identify intracanal pathological changes that are the cause of central stenosis of the lumbar spinal canal.
