There is an increased interest in studying the biomechanics of the facet joints. For in silico
studies, it is therefore important to understand the level of reliability of models for outputs of …

Low back pain is associated with degenerative disc diseases of the spine. Surgical
treatment includes fusion and non-fusion types. The gold standard is fusion surgery, wherein …

Finite element analysis has proven to be a viable method for assessing many structure-
function relationships in the human lumbar spine. Several validated models of the spine …

Lumbar spine fracture is typically treated by means of screw fixation, the primary aim of
which is to reduce fracture by achieving bony union such that the spinal anatomy is restored …

Degenerative diseases of the spine can lead to or hasten the onset of additional spinal
problems that significantly reduce human mobility. The spine consists of vertebral bodies …

The functional biomechanics of the lumbar spine have been better understood by finite
element method (FEM) simulations. However, there are still areas where the behavior of soft …

Biomechanical changes at the adjacent segments after interbody fusion are common
instigators of adjacent segment degeneration (ASD). This study aims to investigate how the …

This paper examines the stress distribution in the posterior fusion fixation, spinal range of
motion (ROM), and the screw–bone interaction force obtained from various fixation methods …

Finite element (FE) method has been widely used to study the screw–bone connections.
Screw threads are often excluded from the FE spine model to reduce computational cost …

BACKGROUND CONTEXT Anterior vertebral body osteophytes are common with
degeneration but their biomechanical influence on the whole lumbar spine remains unclear …
