Biomechanical Analysis of a Three Dimensional Finite Element Model
نویسندگان
چکیده
Low back pain has for long been associated with the lumbar spine biomechanics. A three dimensional model of segments L2 to L5 of lumbar spine is generated form CT images of a healthy human male. Hounsfield units of the image slices are used to derive material properties throughout the 3D model. This model is subjected to finite element analysis to study stresses developed during naturally found loading phenomena. The stresses developed both for flexion and extension are found to be highest in the pedicle region. Also, while flexion produces more stress concentrations, extension balances the compressive body weight, thereby reducing the stress levels. Keyword Lumbar Spine, Biomechanics, Finite Element Analysis.
