Abstract:
A spinal fusion system may include an interbody fusion cage, a fixation plate, and an implanter. The interbody fusion cage may include a proximal region, a distal region opposite the proximal region, a superior region, an inferior region opposite the superior region, and an open volume between the proximal and distal regions. The superior and inferior regions are located between the proximal and distal regions and are configured such that, when the interbody fusion cage is implanted in the disc space, the superior region contracts the inferior end plate and the inferior region contacts the superior end plate. The fixation plate is receivable in the open volume of the interbody fusion cage and includes a superior blade and an inferior blade. At least one of the blades includes a first opening defined therein. The fixation plate is displaceable between a non-deployed state and a deployed state.

Claim (Index 41):
A method for fusing a superior vertebra to an inferior vertebra, the method comprising:\n introducing a trial device into a disc space defined by an inferior endplate of the superior vertebra and a superior endplate of the inferior vertebra, said trial device comprising a body including a superior surface, an inferior surface and an interior opening extending through the superior surface and the inferior surface, and a rotatable blade disposed in the opening of the body, such that a first portion of said rotatable blade can be moved to extend superiorly above the superior surface of the body and a second portion of said rotatable blade can be moved to extend inferiorly below the inferior surface of the body, said body being of size and configuration similar to that of an interbody fusion cage implant; rotating said blade to extend said first portion superiorly above the superior surface of the body and said second portion inferiorly below the inferior surface of the body to cut into said superior endplate and said inferior vertebrae; removing said trial device from said from said disc space; selecting an interbody fusion cage to be of size and configuration similar to that of said trial device body, said interbody fusion cage comprising a superior surface, an inferior surface and an opening extending through said superior surface and said inferior surface, said interbody fusion cage comprising a deployable fixation plate supported within said cage, said fixation plate comprising a pair of movably deployable blades disposed in the opening of said cage, a first blade being movable to extend superiorly above the superior surface of said cage a second blade being movable to extend inferiorly below the inferior surface of said cage; introducing said interbody fusion cage into said disc space; and deploying said fixation plate to move said first deployable blade into said superior endplate cut into by the first portion of said trial device rotatable blade and said second deployable blade into said inferior endplate cut into by the second portion of said trial device rotatable blade.
