Abstract
A fixation implant includes a head, a shank and a distal tip, and one or more of the head, shank and distal tip may be cannulated. The shank includes a threaded ingrowth portion extending from the head to the tapered distal tip that includes external threads, and at least one open network body extending along the length of the ingrowth portion. The open network body selected from one or a combination of a helix, an arrangement of trusses, a scaffold of open and interconnected pores, a porous framework of random open and interconnected pores, and combinations of these.
Claims20
A fixation implant, comprising:
- a shank having a length from a proximal end to a distal end;
- a head that is integral with the shank at its proximal end and has a tool recess configured for engagement with a driving instrument;
- a tip that is integral with the shank at its distal end;
- and
- at least one thread extending along an external surface of the shank,
- wherein at least a portion of the shank, or at least a portion of the shank and one or more of the tip and the head have an open network body comprising a scaffold of open and interconnected pores mimicking a trabecular bone structure, and
- wherein the head has a headless configuration such that the head lacks an enlarged outer diameter relative to the shank.
