Computer modelling of the mechanical behaviour of the cervical spine segment and intervertebral disk prosthesis

摘要

The article describes the model of intervertebral disc prosthesis and the results of study of mechanical behavior of the cervical spine segment. The results show that degenerative changes in the intervertebral disc lead to a change in the location of the regions of maximum Mises stresses in cervical spine segment. The presented geometric model of the intervertebral disc prosthesis is based on the experimental sample of a ceramic endoprosthesis developed at the Institute of Strength Physics and Materials Science SB RAS.
