Abstract
A surgical implant according to an exemplary aspect of the present disclosure includes, among other things, a body that extends along a longitudinal axis between a drive head and a tip. The body includes a cannulation disposed about the longitudinal axis and extending from the tip to the drive head, a solid thread that wraps around the body and a porous region circumferentially extending about the body between adjacent revolutions of the solid thread. In another embodiment, the surgical implant may include a wedge having at least one porous region that extends continuously around a wedge body between an inner wall and an outer wall.
Claims7
An osteotomy wedge for repairing a bone deformity, comprising:
- a body extending between an annular inner wall and an annular outer wall that circumscribe said inner wall, said body having a flat, non-porous top face and a flat, non-porous bottom face that extend between said inner wall and said outer wall, wherein the flat top face and flat bottom face taper towards each other to form a wedge shape, wherein the outer wall forms side walls between the flat top face and flat bottom face of the body, wherein a top side wall and a bottom side wall are formed along a latitudinal axis of the body and said top side wall and bottom side wall are parallel to each other, and wherein two opposite sides walls are formed along a longitudinal axis of the body and said two sides walls taper towards each other;
- a plurality of porous regions between said inner wall and said outer wall and between said top face and bottom face, wherein said plurality of porous regions extend continuously through said body to establish an uninterrupted network of interconnected pores inside said tapered, wedge shaped body;
- a plurality of solid struts, each of the solid struts extending linearly from said inner wall to said outer wall to connect said inner wall to said outer wall, such that the plurality of porous regions are partially compartmentalized by the outer wall, the inner wall, and the solid struts;
- and
- a plurality of vents formed in said inner wall, said outer wall, and said solid struts,
- wherein said inner wall circumscribes an oblong central bore that extends through the top face and the bottom face of said body, and said oblong central bore is larger than each pore of said plurality of porous regions,
- wherein said plurality of porous regions connect to one another through said plurality of vents,
- wherein the plurality of solid struts extend between solid portions of the inner wall and the outer wall and between solid portions of the top face and the bottom face,
- wherein each of the flat top face and flat bottom face defines a bone-contacting surface.
