Effect of cervical spine motion on displacement of posterolateral annulus fibrosus in cervical spondylotic radiculopathy with contained posterolateral disc herniation: a three-dimensional finite element analysis

Journal of Orthopaedic Surgery and Research, 2022
Background Previous studies on dynamic impingement of nerve root in cervical spondylotic radiculopathy (CSR) have focused on effect of cervical spine motion (CSM) on dimensional changes of intervertebral foramen.

A microstructure-based model for a full lamellar-interlamellar displacement and shear strain mapping inside human intervertebral disc core

Computers in Biology and Medicine, 2021
The determinant role of the annulus fibrosus interlamellar zones in the intervertebral disc transversal and volumetric responses and hence on their corresponding three-dimensional conducts have been only revealed and appreciated recently. Their consideration in disc modeling strategies has been proven to be essential for the reproduction of correct ...

Long-term whole-body vibration induces degeneration of intervertebral disc and facet joint in a bipedal mouse model

Frontiers in Bioengineering and Biotechnology, 2023
Background: Whole body vibration (WBV) has been used to treat various musculoskeletal diseases in recent years. However, there is limited knowledge about its effects on the lumbar segments in upright posture mice.

Viscoelastic and Morphologic Changes in the Lumbar Intervertebral Discs of the 5xFAD Mouse Model of Alzheimer's Disease. [PDF]

JOR Spine
The intervertebral discs (IVDs) from mice with amyloid pathologies are larger, flatter, and exhibit increased energy absorption, making these IVDs more susceptible to damage. This heightened vulnerability may predispose elderly individuals with AD to disc injuries, accelerating IVD degeneration and spinal pain. ABSTRACT Background Chronic low back pain,

Integrating MRI-based geometry, composition and fiber architecture in a finite element model of the human intervertebral disc [PDF]

, 2018
Intervertebral disc degeneration is a common disease that is often related to impaired mechanical function, herniations and chronic back pain. The degenerative process induces alterations of the disc’s shape, composition and structure that can be ...

Effect of Load History on Ovine Intervertebral Disc Biomechanics [PDF]

, 2014
Loading of the intervertebral disc (IVD) alters biomechanical properties by modifying fluid distribution in the nucleus pulposus -changing hydrostatic pressure and tissue response- during force transmission along the spine.
