Study Design. We conducted intradiscal pressure measurements with one volunteer performing
various activities normally found in daily life, sports, and spinal therapy. Objectives. The …

Intervertebral disc (IVD) degeneration is an often investigated pathophysiological condition
because of its implication in causing low back pain. As human material for such studies is …

Study design This study investigated the influence of five different muscle groups on the
monosegmental motion (L4–L5) during pure flexion/extension, lateral bending, and axial …

Flexible fixation of fractures with minimally invasive surgical techniques has become increasingly
popular. Such techniques can lead to relatively large fracture gaps (larger than 5 mm) …

Objective. To provide a database of intradiscal pressure measurements together with
anthropometric data as basis for the validation of models that predict spinal loads. Design. …

Study Design. Range of motion, neutral zone, and stiffness parameters of the complete
cervical, thoracic, and lumbar sheep spine were determined in flexion and extension, axial left/…

Compared to a healthy intervertebral disc, the geometry and the material properties of the
involved tissues are altered in a degenerated disc. It is not completely understood how this …

Background The sheep spine is often used as a model for the human spine, although the
degree to which these spines are anatomically comparable has yet to be categorically …

BACKGROUND: Major deficits of many finite element models of the lumbar spine are the
oversimplification, assumed constellation of the material properties or the insufficiently …

Finite element (FE) model studies have made important contributions to our understanding of
functional biomechanics of the lumbar spine. However, if a model is used to answer clinical …
