Abstract:
A system for fusing together opposing vertebra of a spine that defines a disc space therebetween. The system comprises a disc preparation instrument and an inserter assembly for use in the interbody fusion procedure. Disc preparation instrument comprises an elongate handle supporting a trial device at one end thereof. Inserter assembly comprises an elongate inserter supporting at one end thereof an interbody cage implant for insertion into the disc space. Disc preparation instrument provides a scoring element that scribes vertebral endplates at an appropriate scored location for anchor blades on the cage implant to engage the vertebral bodies. Inserter is used to introduce cage implant with anchor blades into the disc space to an appropriate depth so that the blades will be precisely positioned at the scored location created by the scoring element for penetration into the vertebral endplates.

Claim (Index 12):
A method for fusing together a superior vertebra and an inferior vertebra, the superior vertebra including an inferior endplate and a vertebral body, said vertebral body of said superior vertebra having an exterior surface, the inferior vertebra including a superior endplate and a vertebral body, said vertebral body of said inferior vertebra having an exterior surface, the superior and inferior endplates defining a disc space therebetween, the method comprising the steps of:\n introducing into said disc space a trial device supported by a first instrument, said first instrument comprising an adjustable depth stop movable with respect to a first location on said trial device by a selectively adjustable first distance, said first instrument including an indicator device having indicia changeable with and correlated to said first distance; moving said depth stop on said first instrument until said depth stop contacts the exterior surface of one of said superior or inferior vertebrae, thereby establishing a selected first distance; noting an indicia displayed by said indicator device, such indicia being indicative of said selected first distance; providing a second instrument supporting a cage implant, said second instrument comprising an adjustable shoulder serving as a depth stop, said shoulder being movable with respect to a second location on said cage implant by a selectively adjustable second distance correlated with said selectively adjustable first distance, said second instrument including an indicator device having indicia changeable with and correlated to said second distance, such that a display of the same indicia on said first instrument and said second instrument indicates that said first distance and said second distance are substantially equal; moving said shoulder on said second instrument until said indicia on said second instrument indicates the same indicia as the indicia noted on said first instrument; and inserting said cage implant into said disc space until said shoulder contacts the exterior surface of one of said superior or inferior vertebrae, thereby establishing that the depth of said second location within said disc space from the exterior surface of said one of said first or second vertebrae is substantially the same as said selected first distance.
