A 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 کاملOptimal Intervertebral Sealant Properties for the Lumbar Spinal Disc: A Finite-Element Study
BACKGROUND In the lumbar spinal column, an annular disruption may be sealed after annulotomy to prevent further prolapse and instability. We investigated the biomechanical effects of various material properties of an injectable sealant. METHODS We used a 3-dimensional, nonlinear, osteoligamentous, experimentally validated finite-element model of the L3-L5 spine segment to study annulotomies o...

15 صفحه اولProlapsed Lumbar Intervertebral Disc
Cramps in the affected leg are quite common and persistent although sciatic pain may have disappeared completely. A small proportion of patients develop a true recurrent prolapse (prolapse from the same disc) months to years later. This varies in individual statistics, but is probably in the neighbourhood of 4 per cent. to 5 per cent. These recurrent attacks of sciatica, due to a further protru...
متن کاملFinite Element Study of a Lumbar Intervertebral Disc Nucleus Replacement Device
Nucleus replacement technologies are a minimally invasive alternative to spinal fusion and total disc replacement that have the potential to reduce pain and restore motion for patients with degenerative disc disease. Finite element modeling can be used to determine the biomechanics associated with nucleus replacement technologies. The current study focuses on a new nucleus replacement device de...
