Claim:
An interbody spinal implant, comprising: a body generally oval-shaped in transverse cross-section having a top surface, a bottom surface, opposing lateral sides, opposing anterior and posterior portions, and a substantially hollow center, the opposing lateral sides defining a length of the body and the opposing anterior and posterior portions defining a width of the body; at least one transverse aperture located on one or more of the posterior portion, the anterior portion, and at least one of the opposing lateral sides, positioned substantially centrally between the top surface and the bottom surface, extending through the width or the length of the body, and in communication with the substantially hollow center; a single vertical aperture extending from the top surface to the bottom surface and defining a transverse rim with a varying thickness on the top surface and on the bottom surface having an anterior section, a posterior section, opposing lateral sections, and a maximum width at its center; generally rounded, blunt, and radiused intersections defined along the entire lengths between the top and bottom surfaces and the lateral sides, and the top and bottom surfaces and the posterior portion; a roughened surface topography, without teeth, adapted to grip bone and inhibit migration of the implant on at least a portion of the top surface, the bottom surface, or both the top and bottom surfaces that is not generally rounded and blunt; and at least one sharp edge between the top and bottom surfaces and the anterior portion to resist pullout.
