Claim:
An implant comprising: a) a body having an upper end, a lower end, a longitudinal bore defined by a threaded interior surface, and an exterior surface including a thread projecting a first distance from the exterior surface; b) at least one stabilizer arm associated with a corresponding longitudinal slot in the body, said stabilizer arm being hingedly attached to the body and having a bone gripping protuberance projecting laterally outward therefrom, said stabilizer arm being movable from a first position, wherein said bone gripping protuberance is positioned within said longitudinal bore, and a second fully extended position, wherein said bone gripping protuberance extends beyond the exterior surface a second distance which is greater than the first distance, said stabilizer arm being resiliently biased to the first position; c) a camming member longitudinally movable through the longitudinal bore of said body from an initial position to a final position wherein the camming member includes a threaded exterior surface adapted to engage the threaded interior surface of the body, and means for mounting a device including an axial recess defined by a threaded interior surface or an upwardly projecting mounting member; and d) the stabilizer arm, wherein the arm includes a radially inward extending detent at the lower end portion thereof and the camming member includes a circumferential notch engageable with the detent when the camming member is moved to the final position, the detent and notch being configured to lock the camming member in the final position and lock the stabilizer arm in the fully extended second position.
