Claim:
1. A spinal implant for insertion between adjacent upper and lower vertebral endplates, the spinal implant comprising: superior and inferior surfaces for contacting the upper and lower endplates respectively with each surface comprising a plurality of surface teeth; a side wall connecting the superior and inferior surfaces, wherein the side wall comprises an anterior wall and a posterior wall that are connected by a right lateral wall and a left lateral wall, wherein the posterior wall is shorter than the anterior wall such that an angulation between the superior and the inferior surfaces is from about 2 to about 30 degrees; at least one recessed surface formed in the anterior wall, the recessed surface being adapted to receive an insertion tool; and vertical through-channels extending through the implant from the superior surface to the inferior surface with at least one vertical strut separating the channels, wherein a width of the implant is defined as a longitudinal distance between the centers of the right and left lateral walls, a length of the implant is defined as a horizontal distance between the centers of the anterior and posterior walls, and a height of the implant is defined as a vertical distance between the superior and inferior surfaces at an anterior most edge of the implant, the height accounting for a convexity of the superior and inferior surfaces and including one-half of a height of the surface teeth disposed on the superior and inferior surfaces, and wherein the superior and inferior surfaces are convex having respective radius of curvature values defined in a sagittal plane of the implant, the superior radius of curvature value varies from the inferior radius of curvature value, such that the superior and inferior surfaces have different angulation.
