Patent ID: 8182515

Claim:
A dynamic spine stabilization system comprising: an anchor system that is adapted to be secured to the vertebra of the spine; the anchor system including first and second anchors that are adapted to be secured to a first vertebra and third and fourth anchors that are adapted to be secured to a second vertebra and said first, second, third and fourth anchors each including a first, second, third, and fourth head respectively; a first horizontal rod system including a first horizontal rod that can be selectively connected to the first head and the second head of the first and second anchors respectively; said first horizontal rod system including a first deflection rod and a second deflection rod, which first and second deflection rods are mounted to said first horizontal rod; the first deflection rod having a first deflectable end capable of deflecting relative to the first horizontal rod by elastic bending of the first deflection rod in response to a load applied to the first deflectable end; the second deflection rod having a second deflectable end capable of deflecting relative to the first horizontal rod by elastic bending of the second deflection rod in response to a load applied to the second deflectable end; a second horizontal rod having a first end portion for mounting to the third head of the third anchor and second end portion for mounting to the second head of the second anchor; the second horizontal rod including a first vertical rod mount located between the first end portion and the second end portion, and a second vertical rod mount located between the second end portion and the first vertical rod mount; and including vertical rod mounts; and a vertical rod system including a first vertical rod mounted to the first vertical rod mount and having a first end connected to the first deflectable end of the first deflection rod, and a second vertical rod mounted to the second vertical rod mount and having a second end connected to the second deflectable end of the second deflection rod.
