Objective We tried to eatablish pilot lumbar spine 3 d finite element model and to prove the consistency of models with clinic.Methods Through the establishment of pilot lumbar spine 3 d finite element model,high Gz lumbar stress distribution of the environment was simulated, combined with of 48 cases pilot clinical damage of the lumbar spine X-ray analysis.Results pilot lumbar spinal three dimensional finite element model of Lumbar spine was of consistent with the clinical X-ray,stress injury of L1 wedge is high incidence. Conclusion lumbar spinal three dimensional finite element model can simulate the pilot high Gz stress state under the environment of lumbar spine.
