Background Spinal disorders affect millions of people worldwide, and can cause significant
disability and pain. The paraspinal muscles, located on either side of the spinal column, play …

How back pain is related to intervertebral disc degeneration, spinal loading or sports-related
overuse remains an unanswered question of biomechanics. Coupled MBS and FEM …

Purpose Anterior and posterior decompressions for cervical myelopathy and radiculopathy
may lead to clinical improvements. However, patients with kyphotic cervical alignment have …

Background Computational spine models of various types have been employed to
understand spine function, assess the risk that different activities pose to the spine, and …

Objective The oblique lateral locking plate system (OLLPS) is a novel internal fixation with a
locking and reverse pedicle track screw configuration designed for oblique lumbar interbody …

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 …

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 …

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 …

Objective To determine the effects of thoracic stiffness on mechanical stress in the lumbar
spine during motion. Methods To evaluate the effect of preoperative thoracic flexibility, stiff …

Most spine models belong to either the musculoskeletal multibody (MB) or finite element
(FE) method. Recently, coupling of MB and FE models has increasingly been used to …
