1. An intervertebral implant frame comprising:

  • a support member including a body that defines an outer surface, an inner surface spaced from the outer surface in a longitudinal direction, and at least two fixation element receiving apertures that extend through the body;

    a first arm that extends from the support member to a first terminal end, the first arm including a first inner spacer contacting surface, and a first outer surface opposite the first inner spacer contacting surface;

    a second arm that extends from the support member to a second terminal end, the second arm including a second inner spacer contacting surface spaced from the first inner spacer contacting surface along a lateral direction that is perpendicular to the longitudinal direction, and a second outer surface opposite the second inner spacer contacting surface; and

    wherein the inner surface, the first inner spacer contacting surface, and the second inner spacer contacting surface combine to define a void that is configured to receive a spacer body, the void defining a first width measured from the first inner spacer contacting surface to the second inner spacer contacting surface along the lateral direction at a first position, the void defining a second width measured from the first inner spacer contacting surface to the second inner spacer contacting surface along the lateral direction at a second position, and the void defining a third width measured from the first inner spacer contacting surface to the second inner spacer contacting surface along the lateral direction at a third position,wherein the first width is less than the second width, the third width is greater than the first width, the second position is between the first position and the support member with respect to the longitudinal direction, the first position is between the third position and the support member with respect to the longitudinal direction, and the support member defines a fourth width measured in the lateral direction, the first and second arms define a fifth width measured between a first location on the first outer surface and a second location on the second outer surface in the lateral direction, the first and second locations being located on a plane that

         1) is defined by the longitudinal direction and the lateral direction and

         2) passes through at least one of the at least two fixation element receiving apertures, and the fourth width is greater than each of the first, second, third, and fifth widths.
