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.
Claims20
A spinal implant comprising:
- an upper surface, a lower surface, a distal wall, a proximal wall, an anterior sidewall, and a posterior sidewall, wherein said 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;
- a detachable tab coupleable with the first arm, the detachable tab including a fixation aperture therethrough for receiving a fixation anchor, a locking mechanism configured to prevent disengagement of the fixation anchor from the fixation aperture, and an attachment surface sized and shaped to directly couple to an interior facing surface of the first arm in a plurality of positions, wherein at least two of the plurality of positions are offset by a fixed rotational angle, and the attachment surface is sized and shaped to couple to a second arm of the extension in the plurality of positions.
A spinal implant comprising:
- an upper surface, a lower surface, a distal wall, a proximal wall, an anterior sidewall, and a posterior sidewall, wherein said 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;
- a detachable tab coupleable with the first arm, the detachable tab including a fixation aperture therethrough for receiving a fixation anchor, a locking mechanism configured to prevent disengagement of the fixation anchor from the fixation aperture, and an attachment surface sized and shaped to directly couple to an interior facing surface of the first arm in a plurality of fixed positions, wherein at least two of the plurality of positions are offset by a rotational angle in a plane determined by the proximal wall, and the attachment surface is sized and shaped to couple to a second arm of the extension in the plurality of positions.
A spinal implant comprising:
- an upper surface, a lower surface, a distal wall, a proximal wall, an anterior sidewall, and a posterior sidewall, wherein said 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 a posterior side of the proximal wall and a second arm extending proximally from an anterior side of the proximal wall, an interior facing surface of the first arm faces the interior facing surface of the second arm;
- a detachable tab coupleable with the first and second arm, the detachable tab including a fixation aperture therethrough for receiving a fixation anchor, and an attachment surface sized and shaped to directly couple to the interior facing surface of the first arm in a plurality of fixed positions, wherein at least two of the plurality of positions are offset by a rotational angle in a plane determined by the proximal wall, and the attachment surface is sized and shaped to couple to a second arm of the extension in the plurality of positions.
