Patent ID: 8603168

Claim:
A stabilization system for a human spine, comprising: a dynamic interbody device positioned in a disc space between a first vertebra and a second vertebra during use, wherein the dynamic interbody device rotates about a center of rotation during use to facilitate movement of the first vertebra relative to the second vertebra during use; and a posterior stabilization system comprising: a first bone fastener configured to couple to a posterior of the first vertebra during use; a second bone fastener configured to couple to a posterior of the second vertebra during use; a rigid elongated member coupled to the first bone fastener and the second bone fastener during use, wherein the rigid elongated member is arched along at least a portion of its length about a center of curvature to form an arched portion of the rigid elongated member, and wherein the center of curvature of the rigid elongated member substantially aligns with the center of interbody device during use; and a flexible bias member configured to couple to the rigid elongated member, wherein the bias member is configured to provide resistance to movement of the second bone fastener relative to the first bone fastener when the first bone fastener and the second bone fastener are coupled to the first vertebrae and second vertebrae respectively during use.
