1. An intervertebral implant frame configured to support a spacer body in an intervertebral space that is defined by a first vertebral body and a second vertebral body, the intervertebral implant frame comprising:

  • a support member having a body that defines first and second vertebral body facing surfaces, the second vertebral body facing surface spaced from the first vertebral body facing surface along a first direction, the body further defining at least two fixation element receiving apertures that extend through the support member and are each configured to receive a respective bone fixation element,a first tab and a second tab that each extend from the first vertebral body facing surface and are spaced from each other along a second direction that is substantially perpendicular to the first direction so as to define a gap that extends between the first and second tabs along the second direction, each of the first and second tabs being configured to abut the first vertebral body when the intervertebral implant is inserted in the intervertebral space;

    first and second arms that extend from the support member and include, respectively, a first inner spacer contacting surface and a second inner spacer contacting surface that is spaced from the first inner spacer contacting surface along the second direction such that the first arm and the second arm are configured to grip and retain the spacer body, the first arm including a first expansion instrument engagement member defining a first dove-tailed slot open at a distal end of the first dove-tailed slot such that the first dove-tailed slot is configured to receive an expansion instrument in a direction that is opposite an insertion direction of the intervertebral implant frame, the second arm including a second expansion instrument engagement member defining a second dove-tailed slot open at a distal end of the second dove-tailed slot such that the second dove-tailed slot is configured to receive the expansion instrument in the direction that is opposite the insertion direction,wherein the gap is configured to receive a portion of the first vertebral body when each of the first and second tabs abuts the first vertebral body.
