Finite element (FE) method is a proven powerful and efficient tool to study the biomechanics of the human lumbar spine. However, due to the large inter-subject variability of geometries and material properties in human lumbar spines, concerns existed on the accuracy and predictive power of one single deterministic FE model with one set of spinal geometry and material properties. It was confirmed that the combined predictions (median or mean value) of several distinct FE models can be used as an improved prediction of behavior of human lumbar spine under identical loading and boundary conditions. In light of this improved prediction, five FE models (L1-L5 spinal levels) of the human lumbar spine were developed based on five healthy living subjects with identical modeling method. The five models were extensively validated through experimental and computational results in the literature. Mesh convergence and material sensitivity analysis were also conducted. We have shown that the results from the five FE models developed in this paper were consistent with the experimental data and simulation results from the existing literature. The validated modeling method introduced in this study can be used in modeling dysfunctional lumber spines such as disc degeneration and scoliosis in future work.

“…An extended description of the model and its adaptation for the present study are outlined below in this study. The developed lumbar spine FE-model was created based on anatomically accurate geometries and was modeled based on the epidemiology of injuries and disease due to the literature [1,13,11]. FE Analyses were performed using a 3-Dimensional nonlinear model of the spine arraying from L1 to S1, created following multiple processes (Fig.…”

the basic key in the process of our validation may be stated in the development of computational analogues of the spinal morphologies by the creation of sophisticated 3-dimensional Finite element (Fe) model of an intact ligamentous L1-s1 motion segment that matches the real biomechanical behavior of the human lumbosacral spine and for this purpose, the curves were found to be non-linear and the ranges of motion (rom) results were found to compare favorably with reported values from in vivo and in vitro studies as documented in experiments conducted on human cadavers [1,2]. therefore, this Fe-model can be used to investigate the stress and strain distributions in the L1-s1components, especially the discs under physiological functions such as heavy and daily carrying tasks it has the possibility of representing the realities with a much higher degree of fidelity. keywords: Finite element, lumbar spine behavior, ranges of motion, in vivo, in vitro kulcsszavak: végeselem, ágyéki gerinc viselkedése, mozgástartomány, in vivo, in vitroMohammed BenDoUKha research Professor at the university of mostaganem. obtained his engineering degree in mechanical engineering from the university of science and technology of oran (usto).
