Abstract

A dynamic spinal stabilization apparatus comprises a stabilization device such as a rod or a plate. Elongated bores, interfaces, or terminations packed with elastic material provides relative movement between the devices to allow spinal flexion and extension. Initially, relative movement may be constrained by a degradable materials, such as a resorbable material, to allow and screws to fuse to the associated bone.
