Patent attributes
The current invention is directed to a system and method for fusing two adjacent vertebrae. In one embodiment, the vertebrae are fused by inserting a self-broaching interbody apparatus into a disc space without the need for separately drilling and broaching. The self-broaching interbody apparatus may include cutting flutes or other broaching means capable of cutting through the cartilaginous endplates of the vertebrae. In another embodiment, an interbody apparatus with an expanding means capable of distracting the disc space between the adjacent vertebrae is inserted into the disc space. Another embodiment includes a sleeve that fits around an interbody apparatus that has at least one opening in its outer surface leading to a cavity filled with bone and/or ortho-biological materials.
