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 1):
A disc preparation instrument for use in fusing together a superior vertebra and an inferior vertebra, the superior vertebra including an inferior endplate and a vertebral body, the inferior vertebra including a superior endplate and a vertebral body, the superior and inferior endplates defining a disc space therebetween, the disc preparation instrument comprising:\n an elongate handle having a distal end and a proximal end, and a trial device supported by said handle at the distal end thereof, wherein said trial device comprises a trial body of size and configuration approximating the size and configuration of a cage implant for insertion into said disc space, said body having a distal surface, a proximal surface, a top surface and a bottom surface, said top surface having a top opening and said bottom surface having a bottom opening, said body including a movable scoring element having a first portion and a second portion, said scoring element being selectively movable from a first position wherein said first portion and said second portion are disposed interiorly of said device to a second position wherein said first portion extends exteriorly of said body through said top opening for scoring said inferior endplate of said superior vertebra at an upper scored location and said second portion extends exteriorly of said body through said bottom opening for scoring said superior endplate of said inferior vertebra at a lower scored location; and wherein said handle comprises an elongate shaft extending within said handle, said shaft having a distal end extending into said body and attached to said scoring element, said shaft having an actuator at a proximal end, said actuator being operable to move said shaft and thereby said scoring element at the distal end thereof, said handle supporting a movable said depth stop disposed adjacent to the distal end of said handle and being sized and configured to engage an exterior surface of one of said vertebrae when said trial device is disposed in said disc space, said handle having an adjustment knob operable to axially move said depth stop along said handle, said depth stop being spaced axially from said proximal surface of said trial body by a distance that is adjustable upon operation of said adjustment knob.
