An adaptive spinal rod is provided for connecting levels of an adaptive stabilization system to support the spine while providing for the preservation of spinal motion. Embodiments of the adaptive stabilization rod include a ball having an anchor system, a deflection system, a vertical rod system and a connection system. The deflection system provides adaptive stabilization and load-sharing. The adaptive spinal rod connects different levels of the construct in a multilevel construct. The adaptive spinal rod cooperates with the deflection system to further reduce stress exerted upon the bone anchors and spinal anatomy.
1. An adaptive spinal rod adapted to stabilize a spinal segment, wherein the spinal rod comprises: an elongated rod having a first end, a second end and a longitudinal rod axis;an aperture at the first end of the rod;a partially-spherical mount contained in the aperture, the partially-spherical moun
1. An adaptive spinal rod adapted to stabilize a spinal segment, wherein the spinal rod comprises: an elongated rod having a first end, a second end and a longitudinal rod axis;an aperture at the first end of the rod;a partially-spherical mount contained in the aperture, the partially-spherical mount can rotate and pivot within the aperture, wherein the partially-spherical mount has a central axis perpendicular to a base side of the partially-spherical mount;the partially-spherical mount having an elongated slot adapted to receive a post of a bone anchor, wherein the elongated slot has a first dimension perpendicular to the central axis of the partially-spherical mount and a second dimension parallel to the central axis of the partial-spherical mount,wherein the post is loosely coupled to the elongated slot such that the post can slide in the first dimension and the second dimension of the elongated slot, and rotate in the elongated slot; andwherein the bone anchor can be secured relative to the partially-spherical mount while permitting the bone anchor to change in angle relative to the longitudinal rod axis. 2. The adaptive spinal rod of claim 1, in combination with a bone anchor, wherein the bone anchor comprises a threaded shaft adapted to engage a vertebra and a post adapted to mount relative to the partially-spherical mount in the elongated slot. 3. The adaptive spinal rod of claim 1, in combination with a first bone anchor and a second bone anchor, wherein: the first bone anchor comprises a post and a threaded shaft adapted to engage a vertebra;the second bone anchor comprises a head and a threaded shaft adapted to engage a vertebra;wherein the partially-spherical mount is secured relative to the post of the first bone anchor; andwherein the second end of the elongate rod is secured to the head of the second bone anchor. 4. The adaptive spinal rod of claim 1 wherein the aperture is off-set from said longitudinal rod axis. 5. The adaptive spinal rod of claim 1 wherein said elongated slot of said partially-spherical mount is adapted to allow the post to slide along the elongated slot in a direction about perpendicular to a longitudinal axis of the post. 6. The adaptive spinal rod of claim 1 wherein said aperture is linear such that said partially-spherical mount can move linearly in said linear aperture. 7. The adaptive spinal rod of claim 1, wherein the elongated slot is adapted to allow the bone anchor to at least one of slide, pivot and rotate relative to the elongated slot in the adaptive spinal rod. 8. The adaptive spinal rod of claim 1, wherein the elongated slot is adapted to allow the bone anchor to slide, pivot and rotate relative to the elongated slot in the adaptive spinal rod. 9. An adaptive spinal rod adapted to stabilize a spine, wherein the spinal rod comprises: an elongated rod having a first end, a second end, and a longitudinal rod axis;a housing at the first end of the rod;a rod aperture passing through the housing;a race within the rod aperture;a mount contained by the race and movable relative to the race, the mount can rotate and pivot within the rod aperture, wherein the mount has a central axis perpendicular to a base side of the mount;an elongated slot passing through the mount and said elongated slot adapted to receive a post, wherein the elongated slot has a first dimension perpendicular to the central axis of the mount and a second dimension parallel to the central axis of the mount, andwherein the post is loosely coupled to the elongated slot such that the post can slide in the first dimension and the second dimension of the elongated slot, and rotate in the elongated slot. 10. The adaptive spinal rod of claim 9 wherein said mount is spherically shaped and said elongated rod is adapted to slide, rotate and pivot relative to said post. 11. The adaptive spinal rod of claim 9, wherein the elongated rod is adapted to slide, rotate and pivot relative to the post. 12. The adaptive spinal rod of claim 9 wherein the aperture is off-set from said longitudinal rod axis. 13. The adaptive spinal rod of claim 9 wherein said elongated slot is adapted to allow the post to slide along the elongated slot in a direction about perpendicular to a longitudinal axis of the post. 14. The adaptive spinal rod of claim 9 wherein said aperture is elongated such that said mount can move linearly in said elongated aperture. 15. The adaptive spinal rod of claim 9 wherein the elongated slot is one of oval, elliptical, rectangular with rounded corners and race track shaped. 16. An adaptive spinal rod adapted to stabilize a spine, wherein the spinal rod comprises: an elongated rod having a first end, a second end, and a longitudinal rod axis;an aperture located at the first end of the elongated rod;a curved mount contained by the aperture, the curved mount can rotate and pivot within the aperture, wherein the curved mount has a central axis perpendicular to a base side of the curved mount;the curved mount having an elongated slot adapted to receive a post from a bone anchor, wherein the elongated slot has a first dimension perpendicular to the central axis of the curved mount and a second dimension parallel to the central axis of the curved mount; andwherein the post is loosely coupled to the elongated slot such that the post can slide in the first dimension and the second dimension of the elongated slot, and rotate in the elongated slot. 17. The adaptive spinal rod of claim 16 wherein the aperture is off-set from said longitudinal rod axis. 18. The adaptive spinal rod of claim 16 wherein said aperture is linear such that said curved mount can move linearly in said linear aperture.
