Patent ID: 7785351

Claim:
A bone stabilization system for a human spine comprising: a first dynamic interbody device configured to be positioned between a first vertebra and a second vertebra of the human spine, wherein the first dynamic interbody device is configured to facilitate movement of the first vertebra relative to the second vertebra; a first dynamic posterior stabilization system configured to posteriorly couple to the first vertebra and the second vertebra, wherein the first dynamic posterior stabilization system is configured to facilitate and provide dynamic resistance to motion of the first vertebra relative to the second vertebra facilitated by the first dynamic interbody device; and a second dynamic posterior stabilization system configured to posteriorly couple to the first vertebra and the second vertebra, wherein at least one of the first and second posterior stabilization systems comprises: a first bone fastener configured to be coupled to the first vertebra; a second bone fastener configured to be coupled to the second vertebra; an elongate member configured to be coupled to the first bone fastener and the second bone fastener, wherein the elongate member is configured to extend through an opening in the second bone fastener; and a bias member configured to at least partially surround a portion of the elongate member, wherein the bias member is configured to provide dynamic resistance to motion of the first vertebra relative to the second vertebra, and wherein the bias member comprises a first bias member portion configured to be disposed about the elongate member on one side of the second bone fastener and a second bias member portion configured to be disposed about the elongate member on the other side of the second bone fastener.
