摘要：
A stand-alone interbody fixation system having a cage, anterior fixation blade and posterior fixation blade. The cage includes an annular side wall with an open interior and upper and lower surfaces, the cage being configured to fit between end plates of adjacent vertebrae. The anterior fixation blade includes an anterior alignment boss with two opposing outward extending anterior blades with end plate penetrating tips configured to fit within the open interior of the cage. The posterior fixation blade includes a posterior alignment boss with two opposing outward extending posterior blades with end plate penetrating tips configured to fit within the open interior of the cage. The anterior and posterior fixation blades are counter-rotating blades and the anterior alignment boss and posterior alignment boss are configured to receive or engage a deployment instrument having an anterior engagement portion and a posterior engagement portion configured to rotate the anterior and posterior fixation blades from a stowed position to a deployed condition.
