Abstract:
1. A spinal implant for being secured between adjacent vertebrae, the spinal implant comprising: an implant body configured for being inserted between adjacent vertebral bodies in an insertion orientation and rotated between the vertebral bodies to an implanted orientation; outwardly facing sidewall surfaces of the implant body spaced from each other by a predetermined distance and configured to provide low-friction engagement with surfaces of the adjacent vertebral bodies with the implant body in the insertion orientation; a first set of aligned teeth formed on the implant body adjacent one of the sidewall surfaces for frictionally engaging the surface of one of the adjacent vertebral bodies with the implant body rotated to the implanted orientation; a second set of aligned teeth formed on the implant body adjacent the other sidewall surface for frictionally engaging the surface of the one vertebral body with the implant body rotated to the implanted orientation; an anchoring member having a base portion that is fixedly connected to the implant body adjacent and closer to the first set of teeth than the second set of teeth and which extends beyond the first set of teeth; and a bone piercing portion of the anchoring member spaced from the implant body and extending from the base portion toward the other sidewall surface to a position generally between the first and second sets of teeth so that as the implant body and anchoring member fixed thereto are rotated from the insertion orientation to the implanted orientation the second set of aligned teeth engage the surface of the one vertebral body prior to the anchoring member and the first set of aligned teeth.
