Abstract
A posterior dynamic spinal stabilization device utilizing a spinal rod, a fixed anchor, a mobile anchor adapted for both translation and pivoting, a mobile anchor-limiting stop affixed to the rod and an optional bumper-type, a rod with at least one limiting stop. It allows predetermined and prescribed interpedicular motion. It allows the use of traditional pedicle screw-rod placement techniques in a flexible system possessing many treatment options using familiar components that are familiar to the surgeon, and can be used on multiple levels (especially to top off) and can transition loads by limiting displacements.
