Abstract
This investigation was aimed at the evaluation of the borders of individual variability of the human lumbar spine lordosis. 224 nuclear magnetic tomograms of persons of mature age were analyzed using morphometric, statistical methods, method of three-dimensional (3D) computer modeling and finite-element analysis. During the investigation, a hardware-software complex for morphometric research was created together with the new method of development of 3D computer models of the lumbar spine. The application of 3D modeling allowed to extend the knowledge of human spine biomechanics. Tensions and deformations were calculated in all lumbar vertebrae and intervertebral disks on the basis of spine 3D models developed. Finite-element analysis proved that a normal angle of lumbar lordosis was optimal for the transmission of the adequate compression loads, while the extreme forms of individual variability (high degrees of hyper- and hypolordosis), by changing the geometry of the vertebral column, result in the decrease of the functionality of this system.
