Abstract
Three dimensional finite element models of lumbar interbody fusion using rage and screws were constructed for the simulation of stress distribution and maximum displacement. It is also performed to investigate the efforts of osteoporosis and the location of cage on the stress distribution. It is known from the results that the increase of the strength of trabecular bone causes to decrease the stress of cortical bone and to increase the stress of trabecular bone. And it is found that the trend of stress distribution is changed by the change of location of cage and proper location of cage enhances the rate of operational success.
