A 3-D finite element model (FEM) of the lumbar spine (L1–S1) was used to determine the
effect of a large compressive follower pre-load on range of motions (ROM) in all three planes. …

… The LI vertebra and sacrum were anchored in cups using bone cement and pins. The specimen
was mounted in an apparatus with the top cup inclined at approximately 15" of extension …

Study Design. Human cadaveric biomechanical study. Objective. To determine the fixation
strength of laterally directed, cortical pedicle screws under physiological loads. Summary of …

Purpose In this article, we summarize our work on understanding the influence of cervical
sagittal malalignment on the mechanics of the cervical spine. Methods Biomechanical studies …

BACKGROUND CONTEXT: Lumbar fusion has been associated with inconsistent clinical
outcomes and significant complications. Posterior dynamic devices have been developed to …

Object There is limited data on the pullout strength of spinal fixation devices in the thoracic
spine among individuals with different bone quality. An in vitro biomechanical study on the …

Study Design. A cadaveric biomechanical study. Objective. To investigate the biomechanical
behavior of the cervical spine after cervical total disc replacement (TDR) adjacent to a …

Study Design. A biomechanical study using human spine specimens. Objective. To study
postural compensations in lordosis angles that are necessary to maintain horizontal gaze in …

Background. Forward head posture (FHP) may be associated with neck pain and poor
health-related quality of life. Literature describes only qualitative muscle length changes …

MRI allows non‐invasive assessment of intervertebral disc degeneration with the added
clinical benefit of using non‐ionizing radiation. What has remained unclear is the relationship …
