Abstract:
A finite element model of cervical spine was three-dimensionally reconstructed through computed tomography (CT) scan, recording the edges of image using Snigraphics V18.0 software, and calibrating in sequence of point, line, area, and solid. The stress distribution of cervical C_(3-4) was analyzed using compute aided design to validate the availability of reconstructed models. Results showed that the three-dimensional finite element cervical C_(3-4) was feasible in simulation analysis. These indicate that the established three-dimensional finite element models can simulate biomechanical experiments, providing foundations for analyzing biomechanical performance of local structure of this finite element model under various pressure conditions.
