Abstract

A subtalar plate implant ( 12 ) for correcting and/or altering the alignment of a hyperpronated foot ( 10 ) comprises a plate portion ( 22 ) and an insert portion ( 24 ) that is connected to the plate portion ( 22 ). The plate portion ( 22 ) is selectively attachable to a lateral aspect of the calcaneus ( 16 ). The insert portion ( 24 ) is positionable within the subtalar joint ( 18 ). The insert portion ( 24 ) includes a top surface ( 236 ) that is selectively positionable substantially adjacent to a base of the talus ( 14 ), the top surface ( 236 ) being angled to allow the talus ( 14 ) to articulate over the top surface ( 236 ). The insert portion ( 24 ) further includes a bottom surface ( 238 ) that is selectively positionable substantially adjacent to a dorsal surface of the calcaneus ( 16 ). The insert portion ( 24 ) can include a groove ( 356 ) that is formed along the bottom surface ( 238 ) substantially parallel to the plate portion ( 22 ).

Claims (27)

1. A subtalar plate implant for implanting in a foot, the foot including a talus, a calcaneus, and a subtalar joint at the meeting point of the talus and the calcaneus, the subtalar plate implant comprising:

a plate portion including a first and second end, a top and a bottom, that is selectively positionable substantially adjacent to a lateral aspect of the calcaneus, the plate portion including an aperture positioned substantially adjacent to each of the first and second end that is adapted to receive an attacher for selectively attaching the plate portion to the lateral aspect of the calcaneus; and

an insert portion that is connected to the plate portion, the insert portion being at least partially positionable within the subtalar joint when the subtalar plate implant is implanted in the foot; and

wherein a shape of the plate portion and the insert portion can be varied to match anatomical features of the talus and the calcaneus in specific areas where the subtalar plate implant is being implanted.

2. The subtalar plate implant of claim 1 wherein the plate portion is shaped to substantially match a shape of the lateral aspect of the calcaneus adjacent to which the plate portion is selectively positionable.

3. The subtalar plate implant of claim 1 wherein the insert portion includes a top surface that is selectively positionable substantially adjacent to a base of the talus, the top surface being angled to allow the talus to articulate over the top surface.

4. The subtalar plate implant of claim 1 wherein the insert portion includes a bottom surface that is selectively positionable substantially adjacent to a dorsal surface of the calcaneus.

5. The subtalar plate implant of claim 4 wherein the insert portion includes a groove that is formed along the bottom surface.

6. The subtalar plate implant of claim 5 wherein the groove is formed along the bottom surface substantially parallel to the plate portion.

7. The subtalar plate implant of claim 4 wherein the bottom surface is substantially convex-shaped.

8. The subtalar plate implant of claim 4 wherein the bottom surface includes a pair of flat segments that are angled relative to one another.

9. The subtalar plate implant of claim 1 wherein the plate portion and the insert portion are formed from one or more of a metallic material and a polymeric material.

10. A subtalar plate implant for correcting hyperpronation of a foot, the foot including a talus, a calcaneus, and a subtalar joint at a meeting point of the talus and the calcaneus, the subtalar plate implant comprising:

an insert portion that is at least partially positionable within the subtalar joint when the subtalar plate implant is implanted in the foot, the insert portion including a bottom surface that is selectively positionable substantially adjacent to a dorsal surface of the calcaneus, and the insert portion including a groove that is formed along the bottom surface;

an implant body featuring a substantially smooth surface and one or more round edges so as to inhibit any discomfort felt by a patient;

and

wherein a shape of the plate portion and the insert portion can be varied to match anatomical features of the talus and the calcaneus in specific areas where the subtalar plate implant is being implanted.

11. The subtalar plate implant of claim 10 wherein the bottom surface is substantially convex-shaped.

12. The subtalar plate implant of claim 10 wherein the bottom surface includes a pair of flat segments that are angled relative to one another.

13. The subtalar plate implant of claim 10 wherein the insert portion includes a top surface that is selectively positionable substantially adjacent to a base of the talus, the top surface being angled to allow the talus to articulate over the top surface.

14. The subtalar plate implant of claim 10 further comprising a plate portion that is connected to the insert portion, the insert portion extending substantially perpendicularly away from the plate portion, wherein the plate portion is selectively positionable substantially adjacent to a lateral aspect of the calcaneus.

15. The subtalar plate implant of claim 14 wherein the plate portion includes an aperture that is adapted to receive an attacher for selectively attaching the plate portion to the lateral aspect of the calcaneus.

16. The subtalar plate implant of claim 14 wherein the groove is formed along the bottom surface substantially adjacent to the plate portion.

17. A subtalar plate implant for correcting hyperpronation of a foot, the foot including a talus, a calcaneus, and a subtalar joint at a meeting point of the talus and the calcaneus, the subtalar plate implant comprising:

a plate portion that is selectively positionable substantially adjacent to a lateral aspect of the calcaneus, the plate portion being substantially amorphous-shaped, the plate portion including a first end, a second end, a top and a bottom, each of which are curved in shape for patient comfort, wherein the plate portion includes an aperture that is positioned substantially adjacent to each of the first end and the second end, and wherein the plate portion includes an aperture that is positioned substantially adjacent to one of the top and the bottom, each of the apertures being adapted to receive an attacher for selectively attaching the plate portion to the lateral aspect of the calcaneus; and

an insert portion that is connected to the plate portion, the insert portion extending substantially perpendicularly away from the plate portion, the insert portion including a top surface and a bottom surface, wherein the top surface is selectively positionable substantially adjacent to a base of the talus, the top surface being angled to allow the talus to articulate over the top surface; and wherein the bottom surface is selectively positionable substantially adjacent to a dorsal surface of the calcaneus, the insert portion including a groove that is forming along the bottom surface substantially parallel to the plate portion; and

wherein a shape of the plate portion and the insert portion can be varied to match anatomical features of the talus and the calcaneus in specific areas where the subtalar plate implant is being implanted.
