Abstract
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.
Claims30
A spine implant including:
- an anchor system adapted to engage the spine;
- a first rod that can be selectively connected to the anchor system;
- a second rod that can be selectively connected to the first rod;
- and
- said first rod including a rod capture mechanism that can capture the second rod relative to the first rod.

A spine implant including:
- an anchor system adapted to engage the spine;
- a first horizontal rod that can be selectively connected to the anchor system;
- a second vertical rod that can be selectively connected to the first rod;
- said first rod including a rod capture mechanism that can capture the second rod relative to the first rod;
- and
- said 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.

A spine implant including:
- an anchor system adapted to engage the spine;
- a first horizontal rod that can be selectively connected to the anchor system;
- a second vertical rod that can be selectively connected to the first rod;
- said first rod including a rod capture mechanism that can capture the second rod relative to the first rod;
- and
- said rod capture mechanism includes a capture arm formed in said horizontal rod that defines a recess with at least a part of said capture arm that defines said recess separated from said first horizontal rod, said recess allows said second vertical rod to be received in said recess with said second vertical rod about perpendicular to said first horizontal rod, and said rod capture mechanism including a lock mechanism that can urge said capture arm against said vertical rod in order to lock said second vertical rod in said recess relative to said first horizontal rod.
3 more elements
A method for positioning a spine implant in a spine comprising the steps of:
- implanting anchors in the spine;
- securing at least on horizontal rod to the anchors;
- positioning at least one vertical rod relative to said horizontal rod by causing the vertical rod to be moved into a recess in said horizontal rod;
- and
- locking said vertical rod in said recess of said horizontal rod.
