1. An implant configured to be implanted into an intervertebral space between first and second vertebrae, the implant comprising:

  • a first component having;

    proximal and distal ends that are spaced from one another along a first direction;

    first and second sides that are spaced from one another along a second direction, perpendicular to the first direction; and

    a first inner surface and a first outer surface that are spaced from one another along a third direction, perpendicular to both the first and second direction, the first outer surface configured to grip one of the first and second vertebrae, wherein the first component defines a through hole that extends from the first outer surface to the first inner surface along the third direction, and the first component further defines a recess that extends into the first inner surface with respect to the third direction and terminates between the first inner surface and first outer surface, the recess further extending through the first and second sides along the second direction; and

    a second component having a pair of sides that are spaced from one another along the second direction, and having a second inner surface configured to face the first component along the third direction, the second component having a projection that extends between the sides of the pair of sides along the second direction such that the projection has a maximum length along the second direction, a maximum height along the third direction, and a maximum width along the first direction, the maximum length being greater than the maximum height and the maximum width, and the projection being configured to mate with the recess when the second component is coupled to the first component.
