Abstract
Fixation devices for the foot and ankle are based on a design with a central portion between a pair of blade anchors. The central portion may include sharpening, apertures, notches, or protrusions. The fixation devices may engage two or more bone portions.
Claims17
A fixation device comprising:
- a central portion extending along a first direction between a first end and an opposite second end and extending along a second direction between a leading side and a trailing side, wherein the second direction is perpendicular to the first direction;
- a first blade anchor coupled to the first end of the central portion;
- and
- a second blade anchor coupled to the second end of the central portion, wherein the first and second blade anchors extend perpendicular to the central portion, wherein the first and second blade anchors each extend along the second direction between a leading side and a trailing side;
- wherein the trailing sides of the first blade and second blade extend past the trailing side of the central portion along the second direction;
- wherein the leading side of the central portion comprises a first blunt concave portion between the first blade anchor and a middle region of the leading side of the central portion, and a second blunt concave portion between the second blade anchor and the middle region of the leading side of the central portion, wherein the central portion comprises a sharpened leading edge that extends across the middle region of the leading side of the central portion, wherein the sharpened leading edge of the central portion is between the first and second blunt concave portions;
- and
- wherein along the second direction, the leading and trailing sides of the central portion are between the leading and trailing sides of the first blade anchor.

A fixation device comprising:
- a central portion extending along a first direction between a first end and an opposite second end and extending along a second direction between a leading side and a trailing side, wherein the second direction is perpendicular to the first direction;
- a protrusion extending from the leading side of the central portion, wherein the protrusion is a polyhedron with at least one trapezoidal side, wherein the protrusion is wider at a trailing side of the protrusion than at a leading side of the protrusion;
- a first blade anchor having a leading end and a trailing end, coupled to the first end of the central portion;
- and
- a second blade anchor having a leading end and a trailing end, coupled to the second end of the central portion, wherein the first and second blade anchors extend perpendicular to the central portion;
- wherein the trailing ends of the first blade and second blade extend past the trailing side of the central portion along the second direction;
- and
- wherein the leading side of the central portion comprises a first blunt concave portion between the first blade anchor and the protrusion, and a second blunt concave portion between the second blade anchor and the protrusion, wherein the protrusion is between the first and second blunt concave portions.

A fixation device comprising:
- a central portion extending along a first direction between a first end and an opposite second end, extending along a second direction between a leading side and a trailing side, and extending along a third direction between a front side and a back side, wherein the first, second, and third directions are mutually perpendicular;
- a first blade anchor having a leading end and a trailing end, coupled to the first end of the central portion;
- and
- a second blade anchor having a leading end and a trailing end, coupled to the second end of the central portion, wherein the first and second blade anchors extend perpendicular to the central portion, wherein the first and second blade anchors each extend outwardly from the front and back sides of the central portion along the third direction;
- wherein the trailing ends of the first blade and second blade extend past the trailing side of the central portion along the second direction;
- and
- wherein the leading side of the central portion comprises a first blunt concave portion between the first blade anchor and a middle region of the leading side of the central portion, and a second blunt concave portion between the second blade anchor and the middle region of the leading side of the central portion, wherein the central portion comprises a sharpened leading edge that extends across the middle region of the leading side of the central portion, wherein the sharpened leading edge of the central portion is between the first and second blunt concave portions.
