The human spine is a biomechanical structure that allows complex motions while providing stability and protection for the spinal cord during a variety of loading conditions. In this study, finite element models of spine are developed to investigate clinical problems as well as to predict its biomechanical behaviour. This research proposes a combination of an online real-time FE simulator and an offline nonlinear FEA solver. Haptic feedback is provided in the online FE simulator to enhance the human-computer interaction of the system. Primitive results of spinal deformation can be obtained from the haptic online FE simulator. The offline FEA solver provides detailed deformation and strain/stress information based on the primary simulation results from the online FE simulator.
