Abstract

A bone plate has a curved elongated body including a first end portion and a second end portion. The first end portion is laterally offset relative to the second end portion, and includes a plurality of screw holes. A first screw hole is defined by the second end portion. Each of the screw holes of the first end portion are laterally offset from a straight line extending in a direction along a length dimension of the bone plate and bisecting the first screw hole of the second end portion, and each of the screw holes of the first end portion are on the same side of the straight line as one another.

Claims (37)

1. A bone plate, comprising:

a curved elongated body including a first end portion and a second end portion, the first end portion being laterally offset relative to the second end portion;

a plurality of screw holes defined by the first end portion, the plurality of screw holes of the first end portion including a first screw hole of the first end portion;

a first screw hole defined by the second end portion;

a compression slot defined in the second end portion, the compression slot having a longitudinal axis extending in a direction toward the first end portion along an upper surface of the bone plate and passing through the first screw hole of the first end portion, the first screw hole of the first end portion being offset from the compression slot by the greatest distance along the longitudinal axis of the compression slot from among the plurality of screw holes of the first end portion;

wherein each of the screw holes of the first end portion are laterally offset from a straight line extending in a direction along a length dimension of the bone plate and bisecting the first screw hole of the second end portion;

wherein each of the screw holes of the first end portion are on the same side of the straight line as one another; and

wherein the longitudinal axis of the compression slot forms an angle with the straight line.

2. The bone plate of claim 1 , wherein the longitudinal axis of the compression slot bisects the first screw hole of the first end portion.

3. The bone plate of claim 1 , further comprising a substantially V-shaped cross-section.

4. The bone plate of claim 3 , wherein respective portions of a lower surface of the bone plate on opposite sides of an apex of the V-shaped cross-section form an angle of from about 120 degrees to about 170 degrees.

5. The bone plate of claim 1 , wherein the elongated body further comprises a plurality of protruding portions extending from a lower surface of the bone plate and configured to support the elongated body above a bone.

6. The bone plate of claim 1 , wherein the first end portion includes a first lobe and a second lobe, the second lobe being offset from the first lobe along the straight line in a direction toward the first screw hole of the second end portion.

7. The bone plate of claim 6 , wherein the first screw hole of the first end portion is defined in the first lobe, and the second lobe defines a second screw hole of the first end portion.

8. The bone plate of claim 7 , wherein the first end portion further defines a third screw hole intermediate the first and second screw holes and laterally offset from the first and second screw holes.

9. The bone plate of claim 6 , further comprising a recessed portion located between the first and second lobes.

10. The bone plate of claim 1 , wherein:

the first screw hole of the second end portion is a locking screw hole;

the compression slot is a first compression slot offset from the locking screw hole along the straight line in a direction toward the first end portion; and

the second end portion further defines a second compression slot on the opposite side of the locking screw hole from the first compression slot.

11. The bone plate of claim 10 , wherein a longitudinal axis of the second compression slot extending along the upper surface of the bone plate defines an angle of from about 30 degrees to about 50 degrees with respect to the straight line extending along the length dimension of the bone plate and bisecting the locking screw hole of the second end portion.

12. A bone plate, comprising:

an elongated body including a first end portion and a second end portion, the elongated body defining an upper surface and a lower surface and having a V-shaped cross section, the elongated body being curved such that the first end portion is laterally offset relative to the second end portion; and

a plurality of screw holes defined by the first end portion and a plurality of screw holes defined by the second end portion, at least one of the screw holes of the second end portion being a first compression slot oriented such that a longitudinal axis of the first compression slot extending along the upper surface of the bone plate passes through a first screw hole of the first end portion;

wherein the longitudinal axis of the first compression slot forms an angle with a longitudinal axis of the bone plate; and

wherein among the plurality of screw holes of the first end portion, the first screw hole of the first end portion is offset from the first compression slot by the greatest distance along the longitudinal axis of the compression slot.

13. The bone plate of claim 12 , wherein each of the screw holes of the first end portion are laterally offset from a straight line extending in a direction along a length dimension of the bone plate and bisecting a second screw hole of the second end portion, the second screw hole being offset from the first compression slot along the second end portion in a direction away from the first end portion.

14. The bone plate of claim 12 , wherein respective portions of the lower surface of the bone plate on opposite sides of an apex of the V-shaped cross-section form an angle of from about 120 degrees to about 170 degrees.

15. The bone plate of claim 12 , wherein the elongated body further comprises one or more protuberances extending from the lower surface and configured to support the elongated body above a bone.

16. The bone plate of claim 12 , wherein the second end portion further comprises a second compression slot offset from the first compression slot along the second end portion in a direction away from the first end portion, and a longitudinal axis of the second compression slot extending along the upper surface of the bone plate defines an angle with the longitudinal axis of the first compression slot.

17. A method, comprising:

placing a bone plate on an end portion of a long bone, the bone plate including a curved elongated body having a first end portion and a second end portion, the first end portion being laterally offset relative to the second end portion, the first end portion defining a plurality of screw holes, the plurality of screw holes of the first end portion including a first screw hole of the first end portion, the second end portion defining at least one screw hole and a compression slot, the compression slot having a longitudinal axis extending along an upper surface of the bone plate in a direction toward the first end portion and passing through the first screw hole of the first end portion, the first screw hole of the first end portion being offset from the compression slot by the greatest distance along the longitudinal axis of the compression slot from among the plurality of screw holes of the first end portion, each of the screw holes of the first end portion being laterally offset from a straight line extending in a direction along a length dimension of the bone plate and bisecting the at least one screw hole of the second end portion, each of the screw holes of the first end portion being on the same side of the straight line as one another, the longitudinal axis of the compression slot forming an angle with the straight line; and

securing the bone plate to the long bone.

18. The method of claim 17 , further comprising:

making a radially-shaped cut in the long bone; and

wherein placing the bone plate further comprises placing the bone plate such that a screw hole of the first end portion is positioned at the center of a circle having a radius substantially equal to a radius of the radially-shaped cut.

19. The bone plate of claim 1 , wherein the straight line and the longitudinal axis of the compression slot form an angle of from about 10 ° to about 45°.
