the nucleus pulpous of intervertebral disc effect on finite element modeling of spine
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 has a significant impact on the accuracy of results in biomechanical simulation for different modes. methods: in the present study, biomechani...
متن کاملDevelopment of a Micro-Finite Element Model of the Intervertebral Disc using Sub-modeling Techniques
INTRODUCTION The annulus fibrosus (AF) consists primarily of tightly arranged concentric lamellae of parallel type I collagen fiber bundles, elastin, proteoglycans, water and cells, interconnected by translamellar bridging networks [1,2]. Collagen fibers are oriented approximately 25° to 45° to the transverse plane of the disc and are arranged in alternating directions within each successive la...
متن کاملA novel finite element model of the ovine lumbar intervertebral disc with anisotropic hyperelastic material properties
The Ovine spine is an accepted model to investigate the biomechanical behaviour of the human lumbar one. Indeed, the use of animal models for in vitro studies is necessary to investigate the mechanical behaviour of biological tissue, but needs to be reduced for ethical and social reasons. The aim of this study was to create a finite element model of the lumbar intervertebral disc of the sheep t...
متن کاملThe Role of Poroelasticity on the Biomechanics of the Intervertebral Disc: a Finite Element Study
ABSTRACT: The major goal for the present work is to evaluate a biomimetic Finite Element (FE) model of the Intervertebral Disc (IVD). Recent studies have emphasized the importance of an accurate biomechanical modeling of the IVD, which is a highly complex biphasic medium. A novel biphasic poroelastic model was implemented and coupled with Wilson’s model (2005) for biphasic osmotic swelling beha...
متن کاملEffects of Tobacco Smoking on the Degeneration of the Intervertebral Disc: A Finite Element Study
Tobacco smoking is associated with numerous pathological conditions. Compelling experimental evidence associates smoking to the degeneration of the intervertebral disc (IVD). In particular, it has been shown that nicotine down-regulates both the proliferation rate and glycosaminoglycan (GAG) biosynthesis of disc cells. Moreover, tobacco smoking causes the constriction of the vascular network su...
