Abstract
Official abstract text for this publication.
Pedicle-based intradiscal fixation devices, systems, instruments, and methods thereof. An implant for stabilizing an inferior vertebra and a superior vertebra may include a first member and a second member moveably connected to the first member. The implant may have a first, initial insertion orientation and a second, final implantation orientation different from the first, initial insertion orientation. The first member may be configured to be inserted through a pedicle of the inferior vertebra and the second member may be configured to engage bone of the superior vertebra in the second, final implantation orientation.
First claim
Opening claim text (preview).
What is claimed is: 1. An implant for stabilizing an inferior vertebra and a superior vertebra, the implant comprising: an outer tube defining a central longitudinal axis, the central longitudinal axis curved along its length defining a second central longitudinal axis, the second central longitudinal axis curved along its length, positionable within the outer tube, wherein the implant has a collapsed position whereby the inner tube is positioned inside the outer tube, and the implant has an extended position whereby the inner tube extends from the outer tube, a separate segmented tube configured to advance the inner tube and stabilize the outer tube, wherein the outer tube is configured to be inserted through a pedicle of the inferior vertebra in the collapsed position, and the inner tube is configured to engage bone of the superior vertebra in the extended position, wherein the inner tube is configured to be incrementally advanced past a distal end of the outer curved tube and into the superior vertebral body, wherein the segmented tube is configured to drive the inner tube into the superior vertebral body. 2. The implant of claim 1 , wherein the inner tube has one or more ribs extending along the length of the tube. 3. The implant of claim 1 , wherein the outer and inner tubes are hollow. 4. The implant of claim 1 , wherein the segmented tube includes a plurality of articulating links. 5. The implant of claim 4 , wherein each of the links includes a ball and a socket configured to receive the ball of an adjacent link. 6. The implant of claim 1 , wherein the segmented tube is encapsulated by the outer tube in the extended position.
