We aim to develop a finite element model of human spine of surgical training and planning. A precise three-dimensional geometric model of the intervertebral disc has been first created by segmenting and reconstructing the contour of intervertebral disc in spine CT Images; Then three-dimensional finite element model (FEM) of vertebrae has been established based on the geometric model by setting the...
In this paper, a biomechanical analysis method for percutaneous vertebroplasty has been presented. Integrating the anatomical structure from the spine CT images of a patient, a novel three-dimensional geometric model of lumbar functional spinal units (FSUs) has been built. Based on the geometric model, two kinds of three-dimensional finite element models (FEM) of L1-L2 segments for preoperative and...
In order to study the biomechanical mechanism properties of intervertebral disc herniation, combining the CT and MRI data-based anatomical structure of spine. A three-dimensional geometric model of the lumber disk was constructed. Based on the geometric model, a three-dimensional finite element modeling (FEM) for biomechanical analysis has been created. The FEM will represents a promising tool in...
