Scoliosis is a deformity of the spine that in severe cases requires surgical treatment. There is
still disagreement among clinicians as to what the aim of such treatment is as well as the …

Human lumbar motion segment is composed of various components with distinct
contributions to its gross mechanical response. By employing experimental and …

The role of intra-abdominal pressure (IAP) in spinal load reduction has remained
controversial, partly because previous musculoskeletal models did not introduce the …

Background: Chronic back pain is a major health problem worldwide. Although its causes
can be diverse, biomechanical factors leading to spinal degeneration are considered a …

Accurate predictions of spinal loads in subject-specific musculoskeletal models require
precise body segment parameters, including segment mass and center of mass (CoM) …

Passive finite element (FE) models of the spine are commonly used to simulate intact and
various pre-and postoperative pathological conditions. Being devoid of muscles, these …

Finite element (FE) modeling is widely used to study the biomechanical effect of material
properties, surgical procedures, and loading and boundary conditions on the lumbar spine …

Purpose This study exploits a novel musculoskeletal finite element (MS-FE) spine model to
evaluate the post-fusion (L4–L5) alterations in adjacent segment kinetics. Methods Unlike …

Most of the current rigid-body models of the complete thoracolumbar spine do not properly
model the intervertebral joint as the highly nonlinear stiffness is not incorporated …

Spine musculoskeletal (MS) models make simplifying assumptions on the intervertebral joint
degrees-of-freedom (rotational and/or translational), representation (spherical or beam-like …
