Abstract
An implant includes a body having an upper and lower ends, a longitudinal bore defined by a threaded interior surface, and a threaded exterior surface; at least one stabilizer arm associated with a corresponding longitudinal slot in the body, the stabilizer arm being hingedly attached to the body and having a bone gripping protuberance projecting laterally outward therefrom. The stabilizer arm is movable from a first position wherein the bone gripping protuberance is positioned within the bore and a second fully extended position wherein the bone gripping protuberance is positioned outside the threaded exterior surface of the body. The stabilizer arm is resiliently biased to the first position. A camming member is movable through the bore of the body from an initial position to a final position wherein the stabilizer arm is moved to the second stabilizer arm position.
