1. An intervertebral combination internal screw guide and fixation apparatus configured to be inserted into a disc space between a first vertebral body and a second vertebral body and to provide fusion of the first vertebral body to the second vertebral body via biological bone fusion and screw fusion, the apparatus comprising:
an intervertebral spacing implant including a top wall, a bottom wall, and first and second sidewalls, wherein the intervertebral spacing implant defines:
an open space between the top, bottom, first, and second sidewalls capable of receiving bone filling for biological bone fusion,
a first internal screw guide having a first entry opening and a first exit opening, the first entry opening of the first internal screw guide formed at least partially in a top surface of the top wall and the first exit opening formed at least partially in a bottom surface of the top wall and at least partially in a first side surface of the top wall,
a second internal screw guide having a second entry opening and a second exit opening, the second entry opening of the second internal screw guide formed at least partially in the top surface of the top wall and the second exit opening formed at least partially in the bottom surface of the top wall and at least partially in a second side surface of the top wall so as to extend in a direction different than that of the first internal screw guide,
wherein the intervertebral spacing implant further includes:
a first screw securing mechanism positioned in the top sidewall at the first entry opening of the first internal screw guide so as to extend into the first entry opening; and
a second screw securing mechanism positioned in the top sidewall at the second entry opening of the second internal screw guide so as to extend into the second entry opening, wherein the first and second screw securing mechanisms are positioned between the first and second internal screw guides with the first screw securing mechanism positioned nearer the second side surface of the top wall than the first side surface of the top wall and with the second screw securing mechanism positioned nearer the first side surface of the top wall than the second side surface of the top wall;
a first screw having a first screw head and a first threaded body that is sized and configured to be inserted into the first internal screw guide such that the first screw securing mechanism is positioned with respect to the first screw head to restrict the first screw from being removed once the first screw is screwed in place; and
a second screw having a second screw head and a second threaded body that is sized and configured to be inserted into the second internal screw guide such that the second screw securing mechanism is positioned with respect to the second screw head to restrict the second screw from being removed once the second screw is screwed in place.
