1. A threaded bone implant, comprising:
an elongate body extending from a distal end of the bone implant to a proximal end of the bone implant, the elongate body including
one or more helical threads, each of the one or more helical threads extending along at least a portion of the elongate body,
an inner shank from which the one or more helical threads radially extend,
a porous network of interconnected struts disposed radially about the inner shank and about a longitudinal axis of the elongate body, the porous network of interconnected struts extending along a distal region of the elongate body, along a central region of the elongate body, and along a proximal region of the elongate body, the distal region being in a distal half of the elongate body, the proximal region being in a proximal half of the elongate body, and wherein the distal region is adjacent the central region and the proximal region is adjacent the central region,
a plurality of radially extending struts that extend outward from the inner shank to the porous network of interconnected struts,
the porous network of interconnected struts disposed in a helical configuration between the one or more helical threads along at least a section of the elongate body,
the porous network of interconnected struts having an outer dimension that is less than a major diameter of the one or more helical threads, and
wherein the porous network of interconnected struts defines a substantially smooth outer surface.
