Abstract

Claims (64)

1. A bone plate, comprising:

at least one protuberance at a first end;

a first projection at a second end;

a second projection at the second end adjacent to the first projection, wherein the first and second projections extend at least one of away from and toward one another at a first angle and define a channel therebetween, wherein each of the first and second projections have a base portion and a tapered portion at the second end of the bone plate, and wherein the tapered portions are tapered from at least one of a top surface and a bottom surface through the thickness of the bone plate; and

a coupling segment positioned between the first projection and second projection, the coupling segment comprising:

an opening extending through the bone plate at an oblique angle relative to a bottom surface of the bone plate; and

a cover at least partially surrounding the opening, wherein the cover extends from the coupling segment to a position between the first and second projections and into the channel adjacent to the tapered portion at the second end of the bone plate.

2. The bone plate of claim 1 , wherein the first end is a proximal end and the second end is a distal end, wherein the base portions extend from a position distal to the at least one protuberance to the tapered portions and wherein the base portion has a generally uniform thickness.

3. The bone plate of claim 1 , wherein the at least one protuberance comprises:

a first protuberance; and

a second protuberance positioned adjacent to the first protuberance.

4. The bone plate of claim 3 , wherein a portion of the coupling segment is positioned between the first protuberance and the second protuberance.

5. The bone plate of claim 1 , wherein the at least one protuberance comprises:

an opening extending through the bone plate; and

a threaded portion in the opening.

6. The bone plate of claim 5 , wherein the at least one protuberance further comprises:

at least one cutout positioned along the threaded portion, wherein the at least one cutout extends entirely through the threaded portion from a top surface of the bone plate to the bottom surface of the bone plate.

7. The bone plate of claim 1 , wherein the opening of the coupling segment comprises:

a threaded portion in the opening.

8. The bone plate of claim 7 , wherein the coupling segment further comprises:

a concavity adjacent to the opening and positioned between the opening and the at least one protuberance, wherein the concavity is recessed into a top surface of the bone plate adjacent to a portion of a top surface of the cover.

9. The bone plate of claim 8 , wherein the coupling segment further comprises:

at least one cutout positioned along the threaded portion, wherein the at least one cutout extends entirely through the threaded portion parallel with the opening of the coupling segment.

10. The bone plate of claim 3 , wherein the cover extends from a first position between the first protuberance and the second protuberance to a second position between the first projection and the second projection, and wherein the cover extends at an oblique angle from the bottom surface of the bone plate to a first end of the cover positioned on a top side of the bone plate.

11. The bone plate of claim 1 , wherein the first angle is between 15 degrees and 45 degrees.

12. The bone plate of claim 1 , wherein the first and second projections each further comprise an interior linear portion, wherein the interior linear portions each include an upper edge, and wherein at least the upper edges of the interior linear portions extend at least one of away from and toward one another at the first angle and define the channel therebetween.

13. A bone plate system, comprising:

a bone plate, comprising:

at least one tab at a first end;

a second end with a first projection and a second projection adjacent to the first projection, wherein interior surfaces of the first and second projections extend at least one of away from and toward one another at a first angle and define a channel therebetween, wherein each of the first and second projections have a base portion and a tapered portion at the second end of the bone plate, and wherein the tapered portions are tapered from at least one of a top surface and a bottom surface through the thickness of the bone plate; and

a coupling segment positioned adjacent to the at least one tab and between the first projection and the second projection, wherein the coupling segment comprises:

an opening extending through the bone plate at an oblique angle relative to a bottom surface of the bone plate; and

a cover at least partially surrounding the opening, and wherein the cover extends from the coupling segment to a position between the first and second projections and into the channel adjacent to the tapered portion at the second end of the bone plate; and

at least one fastener, comprising:

at least one first fastener for coupling to the at least one tab; and

a second fastener for coupling to the coupling segment.

14. The bone plate system of claim 13 , wherein the at least one tab comprises:

a first tab; and

a second tab positioned adjacent to the first tab.

15. The bone plate system of claim 13 , wherein the at least one tab comprises:

an opening extending through the bone plate;

a threaded portion in the opening; and

at least one cutout positioned along the threaded portion and forming gaps in the threaded portion that extend from a top surface of the bone plate to the bottom surface.

16. The bone plate system of claim 13 , wherein the coupling segment comprises:

a threaded portion in the opening;

at least one cutout positioned along the threaded portion; and

a concavity adjacent to the opening and positioned between the opening and the at least one tab.

17. The bone plate system of claim 14 , wherein the coupling segment is positioned between at least a portion of the first tab and the second tab and extends between the first projection and the second projection.

18. A method for using the bone plate of claim 1 , comprising:

cutting an incision over a patient's bone;

preparing the patient's bone;

selecting the bone plate;

inserting the second end of the bone plate into a second bone portion;

aligning the bone plate on a first bone portion;

inserting at least one fastener through the bone plate and into the first bone portion;

inserting a fastener through the bone plate and into the second bone portion; and

closing the incision.

19. A bone plate, comprising:

at least one protuberance at a first end;

a first projection at a second end;

a second projection at the second end adjacent to the first projection, wherein the first and second projections comprise an interior linear portion, wherein the interior linear portions each include an upper edge, and wherein at least the upper edges of the interior linear portions extend at least one of away from and toward one another at a first angle and define a channel therebetween; and

a coupling segment positioned between the first projection and second projection, the coupling segment comprising:

an opening extending through the bone plate at an oblique angle relative to a bottom surface of the bone plate; and

a cover at least partially surrounding the opening, and wherein the cover extends from the coupling segment to a position between the first and second projections and into the channel adjacent to a tapered portion at the second end of the bone plate.
