Abstract: This application describes implants and methods for fixing two or more motion segments of a spine, particularly two or more motion segments located adjacent to a motion segment that was previously fixed during a prior surgery. An extension rod is described that attaches directly to the original fixation construct at one end. The opposing end of the extension rod is received and locked within a rod receptacle of a newly implanted pedicle screw at the adjacent level.

Abstract: An apparatus and method for shaping an edge of a tile. The preferred embodiment enables an operator to place a tile between an elevator and a reference plate. The operator snugs the edge of the tile up against a reference plate, and causes the elevator to press the tile towards the reference plate. The reference plate and the elevator are coupled with a transporter. The transporter is moved to maintain the tile in contact the guide surface, whereby the edge is placed into an edge shaping zone of a shaping tool, such as a router bit or a saw. Two or more shaping tools may be placed in series along the guide surface whereby the edge may be successively shaped by each shaping tool in a two or multi-stage process. A motor and a lead screw or a chain may be used to move the transporter and tile.
