The implant includes a spacer portion having an inferior and superior surface, wherein the inferior and superior surfaces each have a contact area capable of engaging with anatomy in the treated area, and the inferior and superior surfaces define a through-hole extending through the spacer body. The present invention further provides screw holes extending from a side portion to the inferior and superior surfaces of the spacer portion and a plate portion coupled to the spacer portion through a coupling means, wherein the plate portion contains screws holes for receiving screws. A screw back out prevention mechanism adapted on the plate portion and prevents the back out of screws from the screw holes. ## Claims ### Claim 1 An intervertebral implant for implantation in a treated area of an intervertebral space between vertebral bodies of a spine, wherein said implant comprises: a spacer having, an inferior and superior surface, wherein the inferior and superior surfaces each have a contact area capable of engaging with anatomy in the treated area, and the inferior and superior surfaces define a through-hole having an inner surface extending through the spacer; through holes extending from a side portion to the inferior and superior surfaces of the spacer; a plate rigidly coupled to the spacer, wherein the plate contains through holes for receiving fasteners; and wherein a fastener back out prevention mechanism is adapted on the plate for preventing the back out of screws from the screw holes wherein the plate comprises an extension that is adapted to mate with a connection groove on an anterior portion of the spacer, and wherein the plate is not moveable with respect to the spacer. ### Claim 2 (depends on 1) The intervertebral implant of claim 1, wherein the at least two fasteners are inserted into adjacent vertebral bodies at divergent angles. ### Claim 3 (depends on 1) The intervertebral implant of claim 1, wherein at least one pin rigidly couples the spacer with the plate. ### Claim 4 (depends on 1) The intervertebral implant of claim 1, wherein the plate and the spacer are configured to structurally mate with one another. ### Claim 5 (depends on 1) The intervertebral implant of claim 1, wherein the plate is comprised of metal. ### Claim 6 (depends on 1) The intervertebral implant of claim 1, wherein the at least one groove is configured circumferentially on the inner surface of the spacer. ### Claim 7 (depends on 1) The intervertebral implant of claim 1, wherein the spacer is comprised of plastic. ### Claim 8 (depends on 1) The intervertebral implant of claim 1, wherein the spacer comprises a plurality of protrusions on superior and inferior surfaces of the spacer. ### Claim 9 An intervertebral implant for implantation in a treated area of an intervertebral space between vertebral bodies of a spine, wherein said implant comprises: a spacer having an inferior and superior surface, wherein the inferior and superior surfaces each have a contact area capable of engaging with anatomy in the treated area, and the inferior and superior surfaces define a through-hole and an inner surface extending through the spacer; screw holes extending to the inferior and superior surfaces of the spacer; a plate rigidly coupled to the spacer, wherein the plate contains screws holes for receiving screws; and a screw back out prevention mechanism adapted on the plate and prevents the back out of screws from the screw holes, wherein the plate comprises an extension that is adapted to mate with a connection groove on an anterior portion of the spacer, the extension extending an entire length of the plate and the connection groove extending the entire length of the anterior portion of the spacer, and wherein the plate is not moveable with respect to the spacer. ### Claim 11 (depends on 10) The intervertebral implant of claim 10, wherein the at least two screws are inserted into adjacent vertebral bodies at divergent angles. ### Claim 12 (depends on 10) The intervertebral implant of claim 10, wherein at least one pin couples the spacer portion and the plate of the intervertebral implant. ### Claim 13 (depends on 10) The intervertebral implant of claim 10, wherein the plate and the spacer are configured to structural mate with one another. ### Claim 14 (depends on 10) The intervertebral implant of claim 10, wherein the plate is comprised of metal. ### Claim 15 (depends on 10) The intervertebral implant of claim 10, wherein the spacer comprises a plurality of protrusions on the superior and inferior surfaces of the spacer. ### Claim 16 An implant for positioning between adjacent intervertebral bodies comprising: a spacer having an anterior portion, a posterior portion, first and second side portions, and superior and inferior surfaces; and a plate having an anterior face and a posterior face, first and second side portions, and superior and inferior surfaces; wherein the plate comprises an extension extending out from the posterior portion of the plate and extending the entire length of the plate, wherein the extension of the plate mates with a connection groove of the spacer, the connection groove of the space configured on the anterior portion of the spacer and extending the entire length of the spacer, where connection pins couple the spacer to the plate so that the plate does not move with respect to the spacer.
