Patent ID: 8574301

Claim:
A spinal fusion implant of non-bone construction 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 generally parallel ridges to contact said second vertebra when said implant is positioned within the interbody space, a distal wall, a proximal wall having threaded receiving aperture configured to releasably mate with an inserter tool, a first sidewall, a second sidewall generally opposite from the first sidewall, and a medial support wall extending between the first and second sidewalls and being positioned along a medial plane, wherein said distal wall, proximal wall, first sidewall, second sidewall, and medial support wall comprise a radiolucent material wherein said implant further comprises a pair of lateral grooves positioned in said proximal wall and extending laterally from said threaded receiving aperture; wherein said implant has a longitudinal length extending from a proximal end of said proximal wall to a distal end of said distal wall, said longitudinal length is greater than 40 mm, said implant having a maximum lateral width extending from said first sidewall to said second sidewall along said medial plane that is generally perpendicular to said longitudinal length, said implant having a height extending from said upper surface to said lower surface and extending generally perpendicular to said longitudinal length and said maximum lateral width, wherein said longitudinal length is greater than said maximum lateral width, and said maximum lateral width is greater than said height, wherein the threaded receiving aperture defined in the proximal wall has a central axis generally parallel to said longitudinal length of said implant; and first and second fusion apertures extending through said upper surface and 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, wherein the first and second fusion apertures are positioned on opposite sides of the medial support wall, each of said first and second fusion apertures having: a longitudinal aperture length extending generally parallel to the longitudinal length of said implant, 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.
