Claim:
1. A spinal fusion implant configured to be positioned between a first vertebra and a second vertebra, comprising: a proximal wall, a distal wall, a first sidewall and a second sidewall opposite the first sidewall, the first sidewall and the second sidewall extending between the proximal wall and the distal wall, the implant comprising a longitudinal length extending along a longitudinal axis extending between the proximal wall and the distal wall, a maximum lateral width extending along a lateral axis perpendicular to the longitudinal axis, the longitudinal length being greater than the maximum lateral width; an upper surface of the implant comprising upper surfaces of the proximal wall, the distal wall, the first sidewall and the second sidewall, the upper surface of the implant comprising a first plurality of ridges configured to be in contact with the first vertebra while the implant is positioned between the first vertebra and the second vertebra, and an upper surface of the first sidewall and an upper surface the second sidewall having a first convex curvature; a lower surface of the implant comprising lower surfaces of the proximal wall, the distal wall, the first sidewall and the second sidewall, the lower surface of the implant comprising a second plurality of ridges configured to be in contact with the second vertebra while the implant is positioned between the first vertebra and the second vertebra, and a lower surface of the first sidewall and the second sidewall comprising a second convex curvature; a tool engagement aperture in the proximal wall configured to engage with an insertion tool for delivering the implant to a target position between the first vertebra and the second vertebra; a medial support extending between the first sidewall and the second sidewall along a medial plane of the implant; and a first fusion aperture and a second fusion aperture extending through an entire height of the implant to permit bone growth therewithin between the first vertebra and the second vertebra, the fusion apertures on opposing sides of the medial support, further comprising a first radiopaque marker, a second radiopaque marker, and a third radiopaque marker, the first radiopaque marker comprising at least a portion in the distal wall, the second radiopaque marker comprising at least a portion in the proximal wall, and the third radiopaque marker comprising at least a portion in the first sidewall or the second sidewall.
