Journal ArticleDOI
Analysis of the influence of disc degeneration on the mechanical behaviour of a lumbar motion segment using the finite element method.
Antonius Rohlmann,Thomas Zander,Hendrik Schmidt,Hendrik Schmidt,Hans-Joachim Wilke,Georg Bergmann +5 more
TL;DR: Three-dimensional, nonlinear finite element model of the L3/L4 functional unit was used to study the influence of disc degeneration on motion segment mechanics and found that a mildly degenerated disc increases intersegmental rotation for all loading cases.
Journal ArticleDOI
Application of a new calibration method for a three-dimensional finite element model of a human lumbar annulus fibrosus.
Hendrik Schmidt,Frank Heuer,Ulrich Simon,Annette Kettler,Antonius Rohlmann,Lutz Claes,Hans-Joachim Wilke +6 more
TL;DR: A method was developed for calibrating the two-composite structure of the annulus fibrosus, the ground substance and collagen fibers to fulfil the required range of motion obtained from in vitro results within an accuracy of 99%.
Journal ArticleDOI
Comparison of eight published static finite element models of the intact lumbar spine: Predictive power of models improves when combined together

TL;DR: In this article, the pooled median of individual model results, similar to a probabilistic approach, can be used as an improved predictive tool in order to estimate the response of the lumbar spine.
Journal ArticleDOI
Application of a calibration method provides more realistic results for a finite element model of a lumbar spinal segment.
TL;DR: Predictability and accuracy of the calibrated and non-calibrated finite element model of a lumbar spinal segment for different clinical defects were evaluated and compared.
Journal ArticleDOI
Stepwise reduction of functional spinal structures increase range of motion and change lordosis angle.
TL;DR: The purpose of this study was to quantify the function of anatomical components on lumbar segments for different loading magnitudes and to start a calibration procedure for models with the smallest functional structure (annulus) and to cumulatively add further structures.
