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 rigidly 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 to prevents the back out of screws from the screw holes and to secure the spacer portion to the plate portion of the intervertebral implant.
