Abstract
The present application is directed to intervertebral implants including teeth arranged in a radial pattern to resist expulsion in multiple directions. The teeth may include a variety of shapes and orientations. In one embodiment, the implant includes an annular shape with a central opening. The implant may further be tapered along a section or entirety of an insertion edge to distract the adjacent vertebral members upon insertion of the implant into the intervertebral space.
