Abstract

Purpose of study: To improve the diagnostics of the vertebral canal lateral arthritic stenosis with the patients suffering from degenerative diseases of the lumbar spine on the ground of the vertebral canal structure peculiarities study, back supporting complex study and disease development mechanisms study. Methods used: As the material for the clinical research we used the examination data of 110 patients suffering from the lumbar spine degenerative diseases. All the patients have been clinically examined, including neurological examination, Oswestry disability index study; roentgenometrical study of regular and functional spondylograms; rentgenocontrast ways of study, spiral computer and magnetic resonance imaging tomography of the lower lumber spine. In addition, 92 tomograms of the lower lumbar spine of the patients under the age of 20 have been analyzed. Biomechanical study of the lumbar spine has been carried out with the help of mathematical modeling using finite element method. Classical methods of statistical data manipulation has been used for analysis. Summary of findings In this thesis the authors reveal clinical, roentgenological, computer-tomographic, magnetic resonance tomographic symptoms that accompany lateral recess stenosis. Special features of the structure of the lumbar spine vertebral canal predisposing to the development of lateral recess stenosis have been ascertained and innate character of these special features has been proved. The methodology of determination of vertebrae articular processes spatial orientation has been developed, the character of the arc-shaped process joints asymmetry bringing on the development of lateral degenerative stenosis has been revealed. Mechanisms of the development of this disease have been studied with the help of mathematical modeling using the finite element method. Relationship between findings and existing knowledge: Both the innate character of the lumbar spine trefoil form and a possibility of the nervous roots arthritic compression in the lateral section of the vertebral canal have been known for a long time. Our research established the possible variants of the vertebral canal trefoil form and specific peculiarities of facet joints constitution leading to the development of the lateral recess stenosis. Overall significance of findings: The received data not only allowed to improve the diagnostics of the lateral recess lumbar stenosis but also gave rise to the further study of other degenerative spine diseases development mechanisms, and besides, figure prominently in the designing of facet joints implants.
