Biomechanical study of lumbar spine with artificial disc replacement using three-dimensional finite element method
Biomechanical analyses on lumbar spine under compressive load and flexion torque were performed using a nonlinear three-dimensional finite element method to evaluate the stability of artificial disc replacement. We prepared a validated intact lumbar L4-L5 motion segment and artificial disc inserted motion segment by replacing intact disc with the artificial disc which is being developed. Effect...
متن کاملBiomechanical comparison of three stand-alone lumbar cages — a three-dimensional finite element analysis
BACKGROUND For anterior lumbar interbody fusion (ALIF), stand-alone cages can be supplemented with vertebral plate, locking screws, or threaded cylinder to avoid the use of posterior fixation. Intuitively, the plate, screw, and cylinder aim to be embedded into the vertebral bodies to effectively immobilize the cage itself. The kinematic and mechanical effects of these integrated components on t...
متن کاملEffect of Coating Materials on the Fatigue Behavior of Hip Implants: A Three-dimensional Finite Element Analysis
This study aims to validate, using finite element analysis (FEA), the design concept by comparing the fatigue behavior of hip implant stems coated with composite (carbon/PEEK) and polymeric (PEEK) coating materials corresponding to different human activities: standing up, normal walking and climbing stairs under dynamic loadings to find out which of all these models have a better performance in...
متن کاملThe Biomechanical Study of Extraforaminal Lumbar Interbody Fusion: A Three-Dimensional Finite-Element Analysis
OBJECTIVE Finite-element method was used to evaluate biomechanics stability of extraforaminal lumbar interbody fusion (ELIF) under different internal fixation. METHODS The L3-L5 level finite-element model was established to simulate decompression and internal fixation at L4-L5 segment. The intact finite model was treated in accordance with the different internal fixation. The treatment groups...
متن کاملStress Analysis of the Human Ligamentous Lumber Spine-From Computer-Assisted Tomography to Finite Element Analysis
Detailed investigation on biomechanics of a complex structure such as the human lumbar spine requires the use of advanced computer-based technique for both the geometrical reconstruction and the stress analysis. In the present study, the computer-assisted tomography (CAT) and finite element method (FEM) are merged to perform detailed three dimensional nonlinear analysis of the human ligamentous...
