6 Abstract Master's dissertation was set out on 69 pages with 47 figures, 18 tables and 31 literature sources. The purpose of this work was to investigate the stress-strain state of cervical spine segment by method of finite element modeling with the degradation of the intervertebral disc. The algorithm for constructing a geometric and finite element model by primitives with the experimental dimensions taken from the literature was developed and realized. The developed model allows analyzing the stress-strain state of the segment elements under physiological loading. The algorithm was developed and realized in finite element analysis software system ANSYS. The influence of degenerative disc changes on the stress-strain state of segment was investigated. The field of distribution of von Mises stresses were obtained for the cancellous tissue, for intervertebral disc, as well as the displacements of the disc and the upper vertebra of segment. The developed model can be used for analysis of the stress strain state of the spine segment in health and when degenerative changes. In addition, the algorithm can be used to study the influence of the intervertebral disc implant to change stress strain state of spine.
