Abstract
Posterior dynamic stabilization (PDS) systems arose with the promise of stability without fixation. In particular, these systems address the two prevailing models of spinal biomechanics – the Panjabi model of the Neutral Zone and Mulholland-Segupta theory of abnormal load transmission. By both limiting the range of motion of the diseased level and off-loading the disc space of some axial stress, PDS systems hope to treat back pain while preserving motion. However, these design constraints post a significant design challenge, as demonstrated by the multiple models that have been visited over the years. Though a successful PDS system has yet to emerge, surgeons have found other ways to use the technology, including as an adjunct to improve fusion rates when paired with interbody devices.
