A dynamic stabilization, motion preservation spinal implant system includes an anchor system, a horizontal rod system and a vertical rod system. The systems are modular so that various constructs and configurations can be created and customized to a patient.
1. An anchor assembly comprising: an anchor body comprising an anchor formed in one piece with a yoke;said yoke has first and second arms and forms a U shape;a shaft spanning the yoke of the anchor body between the first and second arms of the yoke;a saddle having a first bore, wherein the shaft is
1. An anchor assembly comprising: an anchor body comprising an anchor formed in one piece with a yoke;said yoke has first and second arms and forms a U shape;a shaft spanning the yoke of the anchor body between the first and second arms of the yoke;a saddle having a first bore, wherein the shaft is received through said first bore;said saddle adapted to receive a member;a compression unit that is positioned in a second bore of the saddle adjacent the shaft, and said compression unit adapted to be adjacent the member received in said saddle;a set that is received in said saddle and adapted to selectively apply force against the member received in said saddle and thereby apply force through said compression unit to said shaft; andwherein said compression unit includes a first recess that is adapted to receive the member and a second recess that can receive the shaft. 2. The anchor assembly of claim 1 wherein said compression unit has a first end and a second end and wherein said first recess is located on said first end and said second recess is located on said other end. 3. The anchor assembly of claim 1 wherein said first recess is not aligned with said second recess. 4. The anchor assembly of claim 1 wherein said first recess is positioned about 90 degrees from said second recess. 5. The anchor assembly of claim 2 wherein said first recess is positioned about 90 degrees from said second recess. 6. The anchor assembly of claim 1 including a saddle mounting element mounted over said shaft and adjacent to said compression unit. 7. The anchor assembly of claim 6 wherein said saddle mounting element is spherical. 8. The anchor assembly of claim 6 wherein said saddle mounting element is cylindrical. 9. The anchor assembly of claim 1 wherein the first recess is cylindrical and the second recess is spherical. 10. The anchor assembly of claim 1 wherein the first recess is cylindrical and the second recess is cylindrical. 11. The anchor assembly of claim 1 including another compression unit positioned adjacent to said set and adapted to engage the member. 12. The anchor assembly of claim 11 wherein said another compression unit includes a recess that is adapted to receive the member. 13. The anchor assembly of claim 1 wherein the shaft has a roughened surface. 14. The anchor assembly of claim 1 whereas the shaft has a textured surface. 15. An anchor assembly comprising: an anchor body including a yoke extending from an anchor;said yoke has first and second arms and forms a U shape;a shaft spanning the yoke of the anchor body between the first and second arms of the yoke;said shaft having a saddle mounting element which encircles the shaft;a saddle having a bore mounted about the saddle mounting element;said saddle adapted to hold a member;a set that is received in said saddle and is adapted to selectively apply force against the member held in the saddle and thereby apply force to and through said saddle mounting element to said shaft. 16. The anchor assembly of claim 15 wherein said saddle mounting element is spherical. 17. The anchor assembly of claim 15 wherein said saddle mounting element is cylindrical. 18. The anchor assembly of claim 15 wherein the shaft has a roughened surface. 19. The anchor assembly of claim 15 whereas the shaft has a textured surface.
