1. An implant device, comprising:
a top plate having an extended anterior wall;
a bottom plate having an extended anterior wall;
a linkage between the top and bottom plates;
wherein a translation mechanism in the bottom plate causes the linkage to move from a collapsed position wherein the extended anterior wall of the top plate and the extended anterior wall of the bottom plate are substantially parallel with each other to an expanded position,
wherein the top plate is pushed away from the bottom plate in a diagonal direction such that the extended anterior wall of the top plate and the extended anterior wall of the second plate form an angle with respect to each other, and
wherein the translation mechanism is activated by a moveable chassis positioned within the bottom plate, and the linkage further includes a rotationally articulating primary link with a spherical head portion located in the chassis, the spherical head portion communicates with an internal wall of the top plate.
