Finite element analysis of lumbar spine

Three-dimensional models of the one and two vertebrae were developed to clarify the mechanical cause of low back pain. The lumbar structures produced allowed the simulation by the performance of finite element analysis of different situation movement. The purpose of this study was to analyze the hig...
