ABSTRACT

The authors give an account of their investigation into the strength characteristics of the vertebrae preparations depending on a number of geometric characteristics of the vertebral bodies, the biological state of the bone tissue (osteoporosis, degenerative and dystrophic changes) and their group belonging. A number of factors has been revealed in some parameters of which it is possible to determine the dynamics of the state of the support function of the injured segment in the modelling of compressive fractures of the vertebral bodies. The results obtained by the authors allow to specify the literature data concerning the strength properties of the compressed vertebral body.
