Abstract:
1. A spinal fusion implant positionable within an interbody space between a first vertebra and a second vertebra, said implant comprising: an upper surface including anti-migration elements to contact said first vertebra when said implant is positioned within the interbody space, a lower surface including anti-migration elements to contact said second vertebra when said implant is positioned within the interbody space, a distal wall, a proximal wall, a first sidewall, and a second sidewall opposite from the first sidewall, wherein the first sidewall intersects the proximal wall and the distal wall, wherein the second sidewall intersects the proximal wall and the distal wall, wherein the implant defines a straight longitudinal axis extending between the proximal wall and the distal wall, wherein said distal wall, proximal wall, first sidewall, and second sidewall comprise a radiolucent material, wherein the proximal wall includes a tooling aperture axially aligned with the longitudinal axis for releasably mating with an inserter tool; wherein said implant has a longitudinal length greater than 40 mm extending from a proximal end of said proximal wall to a distal end of said distal wall and extending parallel to said longitudinal axis, wherein said implant has a maximum lateral width extending from the first sidewall to the second sidewall along a medial plane that is perpendicular to said longitudinal axis, said implant has a maximum height extending from said upper surface to said lower surface and extending perpendicular to said longitudinal length and said maximum lateral width, wherein said wherein the longitudinal length of the implant is at least two and half times greater than the maximum lateral width, and said maximum lateral width is greater than said maximum height; at least a first fusion aperture defined by the implant and extending through the implant from said upper surface to said lower surface and configured to permit bone growth between the first vertebra and the second vertebra when said implant is positioned within the interbody space, said first fusion aperture having: a longitudinal aperture length extending parallel to the longitudinal length of said implant and parallel to the longitudinal axis, and a lateral aperture width extending between said first sidewall to said second sidewall, wherein the longitudinal aperture length is greater than the lateral aperture width, wherein opposing portions of the first and second sidewalls positioned laterally of the first fusion aperture include outwardly bowed regions that are outwardly bowed away from said longitudinal axis along a direction extending between the proximal wall and distal wall, wherein the outwardly bowed region of the first sidewall is symmetric with the outwardly bowed region of the second sidewall relative to said longitudinal axis; and means for radiopaque marking said distal wall being positioned in the radiolucent material of said distal wall, means for radiopaque marking said proximal wall being positioned in the radiolucent material of said proximal wall, and a pair of means for radiopaque marking a location of said medial plane in which said maximum lateral width extends, said pair of radiopaque means extending in said medial plane and being positioned in the radiolucent material of said first and second sidewalls.
