Abstract
A dynamic stabilization system for use with a spinal motion segment includes a first bone anchor assembly, a second bone anchor assembly, a resilient element, and a sheath. The resilient element includes an end portion engageable with the first bone anchor assembly and a resilient portion engageable with the second bone anchor assembly. The resilient element provides resilient resistance when the first and second bone anchor assemblies are moved toward one another and provides no resistance and is separable from the second bone anchor assembly when the first and second bone anchor assemblies are moved away from one another. The sheath surrounds the resilient portion and articulation surface of the second bone anchor assembly.
