1. An intervertebral implant system, comprising:
an implant having a top wall, a bottom wall opposite the top wall, and a plurality of sidewalls extending between the top and bottom walls to define an interior space, wherein a first sidewall of the plurality of sidewalls has a delivery opening that is continuous with the interior space, such that the first sidewall defines inside borders of the delivery opening; and
a cover plate configured to be secured to the implant within the delivery opening of the first sidewall, the cover plate including:
an exterior surface and an interior surface opposite the exterior surface, wherein the interior surface includes a rotating wedge and tabs, wherein the tabs are operably connected to the rotating wedge;
whereby rotation of the rotating wedge causes the tabs to extend outwardly and securely engage the inside borders of the delivery opening to secure the cover plate to the first sidewall; and
wherein the first sidewall includes first and second protrusions and each of the tabs includes a recess configured to receive a respective one of the first and second protrusions therein, to thereby secure the cover plate to the first sidewall.
