  • a spacer portion including a top surface configured to face the superior vertebral body, and a bottom surface configured to face the inferior vertebral body;

    a plate portion coupled to the spacer portion, the plate portion including a top surface, and a bottom surface, the plate portion further including a first bone fixation hole configured to receive a first bone fixation element along a first insertion direction, the plate portion further including a first borehole intersecting with the first bone fixation hole; and

    a first spring biased snapper element disposed at least partially in the first borehole, the first spring biased snapper element configured to prevent the first bone fixation element from backing-out of the first bone fixation hole along a first back-out direction that is opposite the first insertion direction when the first bone fixation element is inserted into the first bone fixation hole, the first spring biased snapper element including a first end that defines a tapered top surface and a flat bottom surface;

    wherein the first spring biased snapper element is moveable to a position such that at least a portion of the first end protrudes into the first bone fixation hole so that when the first bone fixation element is inserted into the first bone fixation hole the flat bottom surface of the first spring biased snapper element at least partially is aligned with the first bone fixation element along the first back-out direction.
