A micro-macro evaluation of the vertebral bony endplate permeability based on computational fluid dynamics
(2011)
Conference report
Open AccessThe intrinsic permeability is an important parameter that describes the resistance of a porous structure to fluid flo w. It has a key role in poroelastic finite element models of spinal segments, especially at ... -
Anisotropic tissue elasticity in human lumbar vertebra, by means of a coupled ultrasound-micromechanics approach
(2012-07-01)
Article
Restricted access - publisher's policyThe extremely fi ne structure of vertebral cortex challenges reliable determination of the tissue's anisotropic elasticity, which is important for the spine's load carrying patterns often causing pain in patients. As a ... -

Comparison of four methods to simulate swelling in poroelastic finite element models of intervertebral discs
(2011-10)
Article
Restricted access - publisher's policyOsmotic phenomena influence the intervertebral disc biomechanics. Their simulation is challenging and can be undertaken at different levels of complexity. Four distinct approaches to simulate the osmotic behaviour of the ... -
Finite element modelling of the spine
(Woodhead Publishing Limited, 2012-03-01)
Part of book or chapter of book
Restricted access - publisher's policyThis chapter focuses on the finite element method applied to spine modelling. First, the functional biomechanics of the healthy spine are presented in terms of load transfers among the different spinal structures ... -
Finite element study of scaffold architecture design and culture conditions for tissue engineering
(2009-10)
Article
Restricted access - publisher's policyTissue engineering scaffolds provide temporary mechanical support for tissue regeneration and transfer global mechanical load to mechanical stimuli to cells through its architecture. In this study the interactions between ... -
In silico evaluation of a new composite disc substitute with a L3-L5 lumbar spine finite element model
(2012-06-21)
Article
Restricted access - publisher's policyWhen the intervertebral disc is removed to relieve chronic pain, subsequent segment stabilization should restore the functional mechanics of the native disc. Because of partially constrained motions and the lack ... -
Nanotechnology in regenerative medicine: the materials side
(2008-01)
Article
Open AccessRegenerative medicine is an emerging multidisciplinary field that aims to restore, maintain or enhance tissues and hence organ functions. Regeneration of tissues can be achieved by the combination of living cells, which ... -
On the collagen criss-cross angles in the annuli fibrosi of lumbar spine finite element models
(2011-04)
Article
Restricted access - publisher's policyIn the human lumbar spine, annulus fibrosus fibres largely contribute to intervertebral disc stability. Detailed annulus models are therefore necessary to obtain reliable predictions of lumbar spine mechanics by finite ... -
Perfusion cell seeding on large porous PLA/calcium phosphate composite scaffolds in a perfusion bioreactor system under varying perfusion parameters.
(2010-12-17)
Article
Restricted access - publisher's policyA promising approach to bone tissue engineering lies in the use of perfusion bioreactors where cells are seeded and cultured on scaffolds under conditions of enhanced nutrient supply and removal of metabolic products. ... -
Regional annulus fibre orientations used as a tool for the calibration of lumbar intervertebral disc finite element models
(2010)
Conference report
Open AccessThe highly organized collagen network of human lumbar a nnulus fibrosus (AF) is fundamental to preserve the mechanical inte grity of the interverte bral discs. In the healthy AF, fibres are embedded in a hydrated matrix ... -
Regional annulus fibre orientations used as a tool for the calibration of lumbar intervertebral disc finite element models
(Gordon and Breach Science Publishers, 2011-01-06)
Article
Restricted access - publisher's policyThe collagen network of the annulus fibrosus largely controls the functional biomechanics of the lumbar intervertebral discs (IVDs). Quantitative anatomical examinations have shown bundle orientation patterns, possibly ... -
Significance of the collagen criss-cross angle distributions in lumbar annuli fibrosi as revealed by finite element simulations
(2010)
Conference report
Open AccessIn the human lumbar spine, annulus fibr osus (AF) fibres la rgely contribute to intervertebral disc (IVD) stability, and deta iled annulus models are required to obtain reliable predictions of lumbar spine biom echanics ... -

Statistical factorial analysis on the poroelastic material properties sensitivity of the lumbar intervertebral disc under compression, flexion and axial rotation
(2009-12)
Article
Restricted access - publisher's policyA statistical factorial analysis approach was conducted on a poroelastic finite element model of a lumbar intervertebral disc to analyse the influence of six material parameters (permeabilities of annulus, nucleus, trabecular ... -
The effect of sustained compression on oxygen metabolic transport in the intervertebral disc decreases with degenerative changes
(2011-08-04)
Article
Open AccessIntervertebral disc metabolic transport is essential to the functional spine and provides the cells with the nutrients necessary to tissue maintenance. Disc degenerative changes alter the tissue mechanics, but interactions ...
