Abstract:
Objective To investigate the protective effect of cerebrospinal fluid(CSF)on the spinal cord in patients with scoliosis and evaluate its buffering effect during gravitational traction surgery and in daily life,so as to provide a theoretical guidance for surgical planning and postoperative rehabilitation of scoliosis.Methods A three-dimensional coupled spinal cord-CSF finite element model was established to simulate the biomechanical responses of the spine under two scenarios:gravitational traction surgery and daily life.Comparative analyses were conducted for conditions with and without CSF,and the buffering effect of CSF was quantitatively assessed.Results During simulated gravitational traction surgery,CSF significantly reduced the stress and deformation of the spinal cord,with the stress in spinal cord white and gray matter decreasing by 65％-90％and deformation decreasing by 70％-95％.In the daily life scenario,CSF provided greater protective effects in lateral flexion and anterior-posterior flexion directions,with stress reductions of 60％-85％.However,in torsion,the buffering effect of CSF was relatively weaker,with stress reductions of only 10％-25％.Conclusions CSF significantly reduces spinal cord stress and deformation during gravitational traction surgery and in daily life,reducing the risk of injury.
