Background A thorough understanding of the biomechanical characteristics of the healthy
human spine is critical in furthering the treatment of spinal pathology. The goal of this study …

Background context Traditional methods for the evaluation of in vivo spine kinematics introduce
significant measurement variability. Digital videofluoroscopic techniques coupled with …

Introduction. Pedicle based posterior dynamic stabilization systems aim to stabilize the
pathologic spine while also allowing sufficient motion to mitigate adjacent level effects. Two …

Study Design. In vitro flexibility testing of the lumbar spine. Objective. The goal of this study
was to evaluate a motion-preserving posterior dynamic stabilization (PDS) implant based on …

Background The influence of interbody cage positioning on clinical outcomes following
lumbar interbody fusion is not well understood, though it has been hypothesized to play a …

Background Interbody fusion cages with integrated fixation components have become of
interest due to their ability to provide enhanced post-operative stability and mitigate device …

Background The application of kinematic data acquired during biomechanical testing to
specimen-specific, three-dimensional models of the spine has emerged as a useful tool in spine …

BACKGROUND: The efficacy of intrafacet bone dowels in promoting lumbar fusion has not
been established. A recently published study indicates a low fusion rate, along with device …

There is currently no universal model or fitting method to characterize the visco-elastic behavior
of the lumbar spine observed in displacement versus load hysteresis loops. In this study, …

Background Pure moment testing is a common method used in cadaveric spine testing. The
fundamental basis for the widespread acceptance of applying a pure moment is uniform …
