Abstract: A cannulated implant for bone fixation is reinforced by inserting a rigid support core into the cannulated implant's cavity to provide a strengthened cannulated system, better mimicking the strength of an implant having a solid length. The rigid support core sits flush against the inner walls of the implant's cavity, avoiding any disruption with any driver placement, and is fixated to the implant by screwing, tamping into place, or by taper cold fusion.
