Bi-directional fixating/locking transvertebral body screw/intervertebral cage stand-alone constructs with vertical hemi-bracket screw locking mechanism

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 first integral screw guide having a first predetermined angle;
• and
• a second integral screw guide having a second predetermined angle;
• a first screw member disposed in the first integral screw guide at the first predetermined angle and at least partially within the intervertebral cage;
• a second screw member disposed in the second integral screw guide at the second predetermined angle and at least partially within the intervertebral cage;
• and
• a screw locking mechanism that secures at least one of the first screw member and the 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,
• wherein the first screw member includes a screw head and a threaded body,
• wherein the second screw member includes a screw head and a threaded body.
