Claim:
1. A universal, intervertebral combination bone fusion spacer and self-drilling screw apparatus for insertion into a disc space between a first vertebral body and a second vertebral body and fusion of the first vertebral body to the second vertebral body via biological bone fusion and screw fusion, the apparatus comprising: an intervertebral cage including: a top wall, a bottom wall, and two sidewalls defining an open space capable of receiving bone filling for the biological bone fusion, and a first internal screw guide and a second internal screw guide each including an internal bore with an entry opening and an exit opening, the entry opening of the internal bore formed only in a top surface of the top wall and the exit opening formed at least partially in a bottom surface of the top wall and at least partially in a side surface of the top wall; and a screw locking mechanism that secures at least one of a first screw member and a second screw member in one of the first internal screw guide and the second internal screw guide, wherein each of the first internal screw guide and the second internal screw guide is angled to orient the first screw member and the second screw bi-directionally in opposite directions, and wherein the screw locking mechanism is configured to engage at least one of a threaded body of the first screw member and a threaded body of the second screw member.
