Abstract
Systems and methods are described for correcting sagittal imbalance in a spine including instruments for performing the controlled release of the anterior longitudinal ligament through a lateral access corridor and hyper-lordotic lateral implants with detachable fixation tabs.
Claims19
A spinal implant comprising:
- an upper surface, a lower surface, a distal wall, a proximal wall, an anterior sidewall, and a posterior sidewall, wherein the spinal implant has a longitudinal length extending from the proximal wall to the distal wall, a width extending from the anterior sidewall to the posterior sidewall, and wherein the longitudinal length is greater than the width of the spinal implant;
- an extension fixedly attached to the proximal wall, the extension comprising a first arm extending proximally from the proximal wall;
- and
- a detachable tab configured to couple with the first arm,
- wherein the detachable tab comprises:
- a fixation aperture extending therethrough, the fixation aperture being configured to receive a fixation anchor,
- a locking mechanism configured to resist disengagement of the fixation anchor from the fixation aperture, and
- an attachment surface configured to couple to an interior facing surface of the first arm in a plurality of positions, wherein the attachment surface has a flower shaped pattern configured to be attached to the interior facing surface in the plurality of positions,
- wherein the detachable tab is configured to be coupled to the proximal wall by a set screw received in a set screw aperture.

A system comprising:
- a spinal implant including:
- an upper surface, a lower surface, a distal wall, a proximal wall, an anterior sidewall, and a posterior sidewall, wherein the spinal implant has a longitudinal axis extending from the proximal wall to the distal wall,
- an extension fixedly attached to the proximal wall, the extension comprising a first arm extending proximally from the proximal wall, and
- a detachable tab configured to couple to the first arm, wherein the detachable tab comprises:
- a fixation aperture disposed therethrough, the fixation aperture being configured to receive a fixation anchor,
- a locking mechanism configured to resist disengagement of the fixation anchor from the fixation aperture, and
- an attachment surface configured to couple to an interior facing surface of the first arm in a plurality of fixed positions, wherein the attachment surface has a flower shaped pattern configured to be attached to the interior facing surface in the plurality of positions, and
- an inserter configured to couple with the spinal implant and configured to position the spinal implant within an intervertebral space between a first vertebra and a second vertebra,
- wherein the detachable tab is configured to be coupled to the proximal wall by a set screw received in a set screw aperture.

A method for correcting a sagittal imbalance in a lumbar spine, comprising:
- creating a lateral access corridor to a target site on the lumbar spine;
- preparing an intervertebral space between a first vertebra and a second vertebra of the lumbar spine for insertion of a spinal implant, the spinal implant comprising:
- an upper surface, a lower surface, a distal wall, a proximal wall, an anterior sidewall, and a posterior sidewall, wherein the spinal implant has a longitudinal axis extending from the proximal wall to the distal wall,
- an extension fixedly attached to the proximal wall, the extension comprising a first arm extending proximally from the proximal wall, and
- a detachable tab configured to couple with the first arm, the detachable tab comprising:
- a fixation aperture extending therethrough for receiving a fixation anchor,
- a locking mechanism configured to resist disengagement of the fixation anchor from the fixation aperture, and
- an attachment surface sized and shaped to couple to an interior facing surface of the first arm in a plurality of fixed positions, wherein the attachment surface has a flower shaped pattern configured to be attached to the interior facing surface in the plurality of positions,
- wherein the detachable tab is configured to be coupled to the proximal wall by a set screw received in a set screw aperture;
- and
- advancing the spinal implant through the lateral access corridor into the intervertebral space.
