Abstract

In this paper, three dimensional finite element analyses have been performed to investigate the biomechanics of vertebroplasty in patient accurate FE models have been constructed from CT images of a PMMA injected vertebra. In order to apply various material properties of the spine(T12), the functional relation between the well known apparent density and HU(Hounsfield unit) from CT image were employed and thus real material properties can be assigned to each element of FE model. The FE analysis showed similar results with the experiments. With this approach accurate analysis of the vertebroplasty and its clinical applications can be expected.
