Abstract

A wedge-shaped bone implant, particularly but not necessarily, for fixing bones of the foot is provided. The implant has bone screw bores that are each configured to hold a bone screw at a particular angle for receipt in a foot bone, eliminating the need to also use a plate. The implant can include an opening that extends through the implant body from one tapered side thereof to the other tapered side thereof. This opening allows the introduction and retention of bone graft material to promote bone fusion. One or both tapered sides of the body may also have teeth, serrations or the like. The implant body may include a hole or the like in the distal aspect thereof. This allows for the insertion of a metallic component (e.g. titanium or tantalum) to allow for the visibility of the extent of the implant body in radiography, x-ray, or the like.

Claims19

Dependent claims

A foot bone implant comprising:

a wedge-shaped body defining an elongated top, a first slanted side, a second slanted side opposite the first slanted side, a first lateral end, a second lateral end opposite the first lateral end, and a bottom that is narrower in width than the elongated top, the first slanted side extending from a first elongated side of the elongated top to a first elongated side of the bottom, the second slanted side extending from a second elongated side of the elongated top to a second elongated side of the bottom, the first lateral side extending from a first lateral side of the elongated top to a first lateral side of the bottom, and the second lateral side extending from a second lateral side of the elongated top to a second lateral side of the bottom;
a first bore extending from the second slanted side to the first slanted side, the first lateral end, the elongated top, and the first lateral side of the elongated top proximate the first elongated side of the elongated top;
and
a second bore extending from the first slanted side to the second slanted side, the second lateral end, the elongated top, and the second lateral side of the elongated top proximate the second elongated side of the elongated top;
a hole extending from the first slanted side, the hole is configured to allow for the insertion of a component visible in radiography or x-ray.
