STUDY DESIGN: This study is a systematic review of published biomechanical studies
involving pedicle screw-based posterior dynamic stabilization devices (PDS) with a special …

Pedicle screw-based dynamic constructs either benefit from a dynamic (flexible)
interconnecting rod or a dynamic (hinged) screw. Both types of systems have been reported …

Posterior dynamic stabilization (PDS) indicates motion preservation devices that are aimed
for surgical treatment of activity related mechanical low back pain. A large number of such …

Background Pedicle-screw-based posterior dynamic stabilization devices are designed to
alleviate the rate of accelerated degeneration of the vertebral level adjacent to the level of …

Dynamic stabilization in a degenerate symptomatic spine may be advantageous compared
with conventional fusion procedures, as it helps preserve motion and minimizes …

As an alternative treatment for chronic back pain due to disc degeneration motion preserving
techniques such as posterior dynamic stabilization (PDS) has been clinically introduced …

Object It is unclear how the biomechanics of dynamic posterior lumbar stabilization systems
and traditional rigid pedicle screw-rod systems differ. This study examined the …

BACKGROUND CONTEXT: Dynamic stabilization is an alternative to fusion intended to
eliminate or at least minimize the potential for adjacent level degeneration. Different design …

Although spinal fusion has been the definitive surgical management of symptomatic lumbar
degenerative conditions, continued reports of adjacent level degeneration and suboptimal …

Background. Recent innovations in dynamic devices have promised a reduction in stress
shielding, protection of adjacent segment degeneration, and decreased implant failure …
