摘要：
Objective-To develop a three-dimensional finite element model of spine for further biomechanical studies. Methods-A 21-year-old male volunteer was included in this study. CT images were used to construct the finite element model of the spine from T1 vertebrae to sacrum. The material properties of biological tissues in the model were based on data of cadaver test and material test in the literatures. The range of motion of the model was compared with the previous study. The model was optimized until that the simulation results were similar with the literature results. Results-The 3D Eh model of spine was developed that contained vertebrae from T1 to sacrum. The model consisted of 509,580 nodes and 445,722 hexahedrons. Conclusions-A 3D Eh model of postoperative spine was successfully developed, which would serve as effective tool for subsequent biomechanical analysis.
