Abstract

This invention relates to an improved structure for an interspinous stabilization device that more evenly distributes loads throughout the adjacent vertebrae than known interspinous stabilization devices, and further readily compensates for graft settling so as to maintain continued axial loading of the graft. More specifically, this invention relates to a medical device that helps in performing a spinal fusion procedure by holding the bone graft in place and stabilizing the facet screw by a plate that is attached to it. The invention also performs a dynamic function that compensates for settling of the bone graft over time. This dynamic function may, if desired, be enhanced by a movement-limiting mechanism that allows extension but not flexion such that the bone graft fusion remains in contact and fusion takes place.
