Influence of cancellous bone existence in human lumbar spine: a finite element analysis

The aim of this study was developed an accurate computational finite element model (FEM) to simulate biomechanical response of human lumbar spine under physiological functions. In reality, anatomical intricate structure of the spine and also complex deformation in the different defection situation,...
