Abstract

Finite element analysis employed for the adjuvant treatment of spinal diseases has yet to consider the effect of gravity on analytical results. This article simulates the gravity environment on the simulated spine of a standing human body to employ finite element analysis and calculate the changes in stress and node displacement of the lumbar spine. Analytical and calculation results demonstrate that in standing pose with the gravity, the stress distribution of each vertebral body surface is five to six times of that of the intervertebral disc, and for the small joint node, the stress and displacement is increased mostly by 16.57% or decreased mostly by 72.36%.
