Abstract:
Finite element analysis can analyze the stress and strain change of object with complex shape,structure,constitution and load condition,and is widely applied to spinal biomechanical studies due to its controllability,reproducibility and versatility in mechanics tests.The article briefly introduced several finite element analysis software,summarized the mechanical characteristics of vertebral body,intervertebral disc,accessories and the ligament and muscle around the spine,and summarized research achievements of finite element analysis in lumbar fusion,concerning the biomechanics of Cage,its influence on lumbar fusion and related surgery choice,dynamic fusion,artificial intervertebral disc and the biomechanical variation of different fusion style after spinal tumor vertebrectomy.Finite element analysis can help understand the spine biomechanics and provide biomechanical reference for lumbar fusion choice.
