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.
