Abstract:
1. A system to prepare vertebral members for an implant comprising: a docking ring forming a window sized to extend over a portion of the vertebral members and a disc space therebetween, the docking ring having a distal side with a plurality of spikes extending outward therefrom to extend within the vertebral members; a mount sized to attach to the docking ring and extend across the window, the mount comprising a receiving section and a second section, the receiving section having a first width different than a width of the second section, the mount extending below the distal side of the docking ring; a plurality of instruments each having a pair of fingers spaced a distance apart to mate with the receiving section and align with the vertebral members; and a locking mechanism mounted within the mount and having a biasing mechanism that is selectively positionable between a first orientation in which the mount is fixedly attached to the docking ring and a second orientation in which the mount can be removed from the docking ring.
