Accuracy of low-field magnetic resonance imaging for differentiating intervertebral disc extrusions and protrusions at the lumbosacral disc space in dogs

Frontiers in Veterinary Science, 2023
Introduction/PurposeMRI features differentiating extrusion from protrusion in thoracolumbar discs have been published, however little specifically evaluates the lumbosacral disc.

Analytical evaluation of stresses and displacements of an intervertebral disc

Journal of Biomechanical Science and Engineering, 2017
Understanding the intervertebral disc response to mechanical loads is important to prevent back injuries. The experimental and the finite element methods are widely used for that purpose but methodological triangulation is deficient due to lack of a complementary method. This study aims at choosing theories and assumptions that could be used to develop

Surgical tactics for multilevel displacements of lumbar intervertebral discs

Ukrainian Neurosurgical Journal, 2019
Purpose. To improve the results of surgical treatment of lumbar pain syndromes and radiculopathy caused by the multilevel displacement of the intervertebral discs in the lumbosacral spine.Materials and methods. During 2014 through 2018, we examined and treated 3,045 patients with lumbar pain and radiculopathy caused by the displacement of the lumbar ...

EXPERIENCE OF THE OPERATIVE TREATMENT OF DOGS AT DISPLACEMENTS OF INTERVERTEBRAL DISCS

Bìoresursi ì prirodokoristuvannâ, 2018
Relevance. Fractures of the spine, subluxations and dislocations, herniated discs can lead to the development of acute tetraparesis or tetraplegia as a result of bleeding and compression of the thoracolumbar spinal cord [5]. In addition to direct traumatic damage to the spinal cord, secondary neurotoxic processes develop with the formation of free ...

The Nucleus Pulpous of Intervertebral Disc Effect on Finite Element Modeling of Spine

International Clinical Neuroscience Journal, 2016
Background: Spine of an adult is made up of five areas that include 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, sacrum and finally coccyx. Selecting appropriate assumptions for modeling and biological analysis of the spine components

Changes in intervertebral disc morphology persist 5 mo after 21-day bed rest [PDF]

, 2011
As part of the nutrition- countermeasures (NUC) study in Cologne, Germany in 2010, seven healthy male subjects underwent 21 days of head-down tilt bed rest and returned 153 days later to undergo a second bout of 21-day bed rest. As part of this model,

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 ...

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.

Intervertebral disc characterization by shear wave elastography: an in-vitro preliminary study [PDF]

, 2014
Patient-specific numerical simulation of the spine is a useful tool both in clinic and research. While geometrical personalization of the spine is no more an issue, thanks to recent technological advances, non-invasive personalization of soft tissue’s ...
