A new spinal implant has been designed and biomechanical testing completed, intended
for application to" short-segment" spinal defects such as disc degeneration, fracture, …

Acupuncture needle manipulation gives rise to “needle grasp,” a biomechanical phenomenon
characterized by an increase in the force necessary to pull the needle out of the tissue (…

Vertebral transpedicular screws provide secure attachment for posterior spinal fixation
devices. Screw design details, biomechanics, and implantation safety depend upon anatomic …

During acupuncture treatments, acupuncture needles are manipulated to elicit the characteristic
“de qi” reaction widely viewed as essential to acupuncture's therapeutic effect. De qi has …

Extensive development of spinal instrumentation has occurred recently, benefitted by
improved biomechanical knowledge. Reviewed here are various devices and the major …

The effects of injury to the intervertebral disc were investigated using three-dimensional
flexibility and creep measurements of functional spinal units from fresh cadaver lumbar spines. …

Background Although the connective tissues forming the fascial planes of the back have been
hypothesized to play a role in the pathogenesis of chronic low back pain (LBP), there have …

In a random, controlled laboratory study, pedicle screws placed in human cadaveric vertebrae
were axially loaded to failure. Three repair methods were tested. Use of low pressure …

Improvement in the strength of the transpedicular screw-vertebra interface by increasing the
depth of screw insertion may provide improved performance of spinal implants using such …

In each of eight thoracolumbar human cadaveric vertebrae, a hole was made through one
pedicle into the vertebral body with a drill bit and through the contralatera1 pedicle with a …
