Abstract
Implant fixation systems, kits and methods for interbody fusions are described herein. Preferably, the implant has a cage containing two deployable blades and one or more strike plates that are able to deploy the blades. The blades are positioned inside the cage such that one blade faces upward and the other blade faces downward. Protrusions on the ends of the blades fit into correspondingly shaped tracks on the interior surface of the cage, allowing movement of the blades inside the cage. The implant also has two wedge-shaped strike plates that fit into attachment regions located on the blades, which allow the strike plates to slide. Impaction of the strike plate(s) causes them to push the blades superiorly or inferiorly. In the impaction position, a portion of the blades protrudes beyond the superior and the inferior surfaces of the cage and fixes the cage in the adjacent vertebral bodies.
