Abstract
A spinal fusion implant device is provided for insertion into a generally cylindrical bore formed between adjacent vertebrae. The device includes: a shaft having a longitudinal central axis; and a plurality of projections extending radially from the shaft and terminating in a surface, each of the projections being oriented to form a thread like segment for engaging the internal surface of the cylindrical bore to advance the device axially into the bore upon rotation of the device about the longitudinal axis. In an embodiment, each of the projections includes an elongated member terminating in a surface including at least one rib adapted to form a thread like segment for engaging the internal surface of the bore. The elongated member further includes a bulbous head forming the surface at a distal end of the elongated member.
