A spinal fusion implant (100) for insertion between adjacent vertebral bodies has opposed upper and lower surfaces (110,112) adapted to contact each of the adjacent vertebral bodies from within the disc space, a leading end (102) for insertion between the adjacent vertebral bodies, and a trailing end (104) opposite the leading end. The trailing end has an exterior surface and an outer perimeter with an upper edge and a lower edge adapted to be oriented toward the adjacent vertebral bodies, respectively, and a plurality of bone screw receiving holes (126). At least one of the bone screw receiving holes is adapted to only partially circumferentially surround a trailing end of a bone screw received therein. At least one of the bone screw receiving holes passes through the exterior surface and one of the edges so as to permit the trailing end of the bone to protrude beyond one of the edges.
