A spine implant including: an anchor system adapted to engage the spine;the anchor system including a first anchor having a first anchor head, and a second anchor having a second anchor head;a first horizontal rod having a first end portion for mounting to the first anchor head and a second end portion for mounting to the second anchor head, and a center midway between the first end portion and the second end portion;a second vertical rod that can be selectively connected to the first rod;said first rod including a rod capture mechanism positioned between the first end portion and the center of the first rod, the rod capture mechanism configured to capture and secure the second vertical rod to the first rod at a position more medial than the first anchor head; andsaid rod capture mechanism includes a recess that allows said second vertical rod to be received in said recess with said second vertical rod about perpendicular to said first horizontal rod. 14. The spine implant of claim 13 wherein said rod capture mechanism is formed in the first horizontal rod. 15. The spine implant of claim 13 further comprising: a third rod that can be selectively connected to the first rod; andsaid first rod including another rod capture mechanism positioned between the second end portion and the center of the first rod, the another rod capture mechanism configured to capture and secure the third rod to the first rod at a position more medial than the second anchor head. 16. The spine implant of claim 13 wherein said rod capture mechanism includes a capture arm formed from the first horizontal rod and still attached to the first horizontal rod. 17. The spine implant of claim 13 wherein said rod capture mechanism includes a U-shaped capture arm formed from the first horizontal rod with a portion of said U-shaped capture arm remaining attached to the first horizontal rod. 18. The spine implant of claim 13 wherein said rod capture mechanism includes a capture arm that defines said recess that can receive the second vertical rod, which said recess is about cylindrical with an axis of rotation about perpendicular to said first horizontal rod. 19. The spine implant of claim 13 wherein said rod capture mechanism includes said recess that can receive said second vertical rod, which rod capture mechanism can be urged relative to said second vertical rod. 20. The spine implant of claim 13 wherein said rod capture mechanism includes a capture arm and a set screw, which set screw can be used to lock said second vertical rod in said capture arm. 21. The spine implant of claim 13 wherein said rod capture mechanism includes a capture arm which defines said recess that can receive said second vertical rod, and an eccentric headed set screw that can be turned to urge said capture arm against said second vertical rod in order to lock said second vertical rod relative to said first horizontal rod. 22. The spine implant of claim 13 wherein said rod capture mechanism includes a capture arm which is machined from said first horizontal rod, said capture arm is about U-shaped with a portion of said U-shaped capture arm attached to said first rod, which capture arm defines said recess that can receive said second vertical rod, and an eccentric headed set screw that can be turned to urge said capture arm against said second vertical rod in order to lock said second vertical rod in said recess and relative to said first horizontal rod. 23. The spine implant of claim 13 wherein said rod capture mechanism includes a living hinge. 24.
