It is often said that magnetic lines of force in a conducting fluid move with the fluid. In the case
of a plasma, this means that the lines of force move with the particle drift velocity 1 v p = ( E …

BACKGROUND CONTEXT Surface strain on instrumentation spanning the lumbosacral
junction is often recorded during in vitro studies evaluating the biomechanical effects of different …

junction is often recorded during in vitro studies evaluating the biomechanical effects of different …

BACKGROUND CONTEXT: Summary of background data. The biomechanical effects of a
new interbody spacer inserted through a left oblique lumbar approach have not been studied …

Objective: There is resurgence in facet screw use; however, there is a paucity of data
comparing the stability of transfacet pedicle screws (TFPS) to standard pedicle screw-rod …

A study is made of so-called “finite-orbit effects” in a two-dimensional guiding-center plasma.
The macroscopic mass motion of the plasma is represented on the basis of a simple …

BACKGROUND CONTEXT Variations in load distribution based on surface strain on
instrumentation spanning the lumbosacral junction during in vitro loading are often used to evaluate …

BACKGROUND CONTEXT: Screw size and insertion angle can have a significant effect on
the fixation strength in vertebral bone (ref.). A cortical screw (CS) has a trajectory that is more …

BACKGROUND CONTEXT: Kinematic data from in vitro flexibility tests involving cadaveric
spines are often used to validate finite element models of human spine segments. Despite a …
