1. An apparatus for stabilization of bones comprising:
a spacer implant portion;
said spacer implant portion comprising a body;
said body having a height sized to fit within a portion of an intervertebral disc space; said body comprising opposed first and second surface portions for spacing adjacent vertebral bodies;
a pair of opposed channels extending into said opposed first and second surface portions;
one or more stabilizer implant portions for extending between said spacer implant portion and an intervertebral body;
said stabilizer implant portion comprising a base wall captured within one of said opposed channels of said body of said spacer implant portion;
said stabilizer implant portion comprising a cylindrical wall;
said cylindrical wall comprising a central bore sized for holding a bone screw therein;
said cylindrical wall spaced from said base wall;
a web wall extending between said cylindrical wall and said base wall;
said cylindrical wall comprising a leading end;
said web wall comprising a sharp leading edge;
said sharp leading edge of said web wall generally aligned with said leading end of said cylindrical wall;
said web wall extending to a proximal end of said cylindrical wall;
said stabilizer implant portion comprising a proximal face on said web wall generally aligned with a proximal end of said spacer implant portion in an operative relationship;
a stabilizer bone screw separable from said stabilizer cylindrical wall and operable to secure said stabilizer implant portion and said spacer implant portion at a predetermined position with an intervertebral space;
said stabilizer bone screw at least partially seated within said central bore;
said stabilizer bone screw comprising a drive head;
said drive head housed within said central bore of said cylindrical wall in a locked state;
said drive head sized to advance against said stabilizer implant portion;
said stabilizer bone screw comprising bone screw threads operable to thread into bone thereby securing said stabilizer implant portion, said spacer implant portion, and said stabilizer bone screw in a predetermined position within an intervertebral space; and
said bone screw threads passable through said central bore of said cylindrical wall for threading said stabilizer bone screw into bone in a locked state.
