Transverse isotropic elastic properties of vertebral trabecular bone matrix measured using microindentation under dry conditions (effects of age, gender, and vertebral level)
TL;DR: Insight is provided in the transverse isotropic properties of trabecular bone matrix related to age, gender, microanatomical location, and anatomic direction for a broad spectrum of human vertebrae.
Biomechanical in vitro evaluation of the complete porcine spine in comparison with data of the human spine
TL;DR: It appears that the use of the porcine spine could be an alternative to human specimens in the field of in vitro research, but it has to be emphasized that the porCine spine is not a suitable biomechanics surrogate for all regions of the human spinal column.
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.
A pedicle screw system and a lamina hook system provide similar primary and long-term stability: a biomechanical in vitro study with quasi-static and dynamic loading conditions
Hans-Joachim Wilke,Dominik Kaiser,David Volkheimer,Carsten Hackenbroch,Klaus Püschel,Michael Rauschmann +5 more
TL;DR: Simulating in an in vitro experiment the postoperative long-term situation in elderly osteoporotic patients to compare two different stabilization principles; a pedicle screw system and a lamina hook system showed that the ROM was strongly reduced after instrumentation similar for both implants in all motion planes.
Stepwise reduction of functional spinal structures increase vertebral translation and intradiscal pressure.
TL;DR: Results provided by these studies may be used as a database for researchers aiming to calibrate or validate finite element models of L4-5 segments and intradiscal pressure correlated well with data of range of motion for rotation.
