Patent Images
1. An allograft spinal implant comprising:
- a generally planar superior end face;
a generally planar inferior end face; and
a first generally curved sidewall extending between the superior end face and the inferior end face, the first sidewall terminating at first and second generally planar end walls extending between the superior end face and the interior end face, the first and second end walls both angularly crossing the first generally curved sidewall;
at least one of the superior end face and the inferior end face having a plurality of concentric circular arc continuous non-serrated ridges, at least some of the concentric circular arc continuous ridges of the plurality of concentric circular arc continuous ridges extending from the first end wall to the second end wall.

Abstract
An allograft spinal implant includes a generally planar superior end face, a generally planar inferior end face and a generally cylindrical sidewall. The generally cylindrical sidewall extends between the superior end face and the inferior end face. At least one of the superior end face and the inferior end face includes a plurality of concentric circular ridges.

20. An allograft spinal spacer comprising:
-
a first curved sidewall having an outer generally convex surface, an inner surface, and generally planar superior and inferior surfaces defining a first height therebetween; a second curved sidewall having an outer generally concave surface, an inner surface facing the inner surface of the first curved sidewall, and generally planar superior and inferior surfaces defining a second height therebetween; first and second generally planar end walls connecting the first curved sidewall to the second curved sidewall, the first and second generally planar end walls extending between the superior and inferior surfaces of the first and second curved sidewalls and oriented at an angle relative the outer and inner surfaces of the first and second curved sidewalls; and a plurality of concentric arc continuous non-serrated ridges defined on the superior or inferior surface of at least one of the first and second sidewalls. - View Dependent Claims (21, 22, 23)
