The research of spine related disease is an emerging interdisciplinary subject and the key point is the spinal biomechanical properties.In this paper,the method of studying biomechanical properties of lumhar and cervical vertebra based on 3D finite element model is analyzed.Three kinds of method in building finite element model are specified:geometric modeling method,3D coordinatngraphic modeling method and image modeling method.The three key steps of image modeling method for building of basic geometric model are extracted as defining material behavior of vertebra and soft tissue,defining boundary condition,and confirming of the model.Then two principal improving aspects of building finite element model and the foreground of the research are discussed.
