Intervertebral fusion implant

A method of implanting an orthopedic device for vertebral bodies of a spine, said method comprising:

• accessing an intervertebral space from a lateral approach;
• removing a portion of a disc from the intervertebral space;
• positioning an intervertebral implant within the intervertebral space;
• and
• fastening the intervertebral implant into one or more bones via a first anchor and a second anchor,
• wherein the intervertebral implant comprises:
• a spacer portion having an inferior and a superior surface, an anterior surface, posterior surface, and first and second sides, wherein the inferior and superior surfaces each have a contact area capable of engaging adjacent bone members, and the inferior and superior surfaces define a through-hole extending through the spacer portion;
• a plate portion coupled to the anterior surface of the spacer portion, wherein the plate portion comprises at least a first hole and a second hole extending from an anterior surface of the plate to a posterior surface of the plate, wherein the at least first hole is configured to receive the first anchor and the second hole is configured to receive the second anchor;
• and
• a back out prevention mechanism positioned on the anterior surface of the plate portion, wherein the fastener back out prevention mechanism prevents the back out of the first anchor from the first hole and the second anchor from the second hole,
• wherein a length of the spacer portion from the anterior surface to the posterior surface is greater than a distance from a first side to a second side of the plate portion,
• wherein a length of the spacer portion from the first side to the second side is greater than the distance from the first side to the second side of the plate portion, and wherein the spacer portion and the plate portion are configured to be positioned laterally in an intervertebral space.
