Abstract

A bone plate includes (a) a body having a first surface which, in an operative configuration, faces away from a bone on which the plate is to be mounted and a second surface, which in the operative configuration, faces the bone, the body including a first section extending along a first longitudinal axis and a second section extending along a second longitudinal axis angled with respect to the first longitudinal axis; (b) a first hole extending through the body from the first surface to the second surface and defining a first hole axis, the first hole being structured to lockingly engage a head of a first bone anchor inserted therein such that a shaft of the first bone anchor extends along the first hole axis; and (c) a second hole extending through the body and spaced apart from the first hole. The second hole defines a second hole axis and is structured to lockingly engage a head of a second bone anchor inserted therein such that a shaft of the second bone anchor extends along the second hole axis. The first and second hole axes defines a single plane and intersecting at a point on a side of the bone plate facing the second surface.

First claim

What is claimed:

1. A bone plate, comprising:
a body having a first surface which, in an operative configuration, faces away from a bone on which the plate is to be mounted and a second surface, which in the operative configuration, faces the bone, the body including a first section extending along a first longitudinal axis and a second section extending along a second longitudinal axis angled with respect to the first longitudinal axis;
a first hole extending through the body from the first surface to the second surface and defining a first hole axis, the first hole being structured to lockingly engage a head of a first bone anchor inserted therein such that a shaft of the first bone anchor extends along the first hole axis;
and a second hole extending through the body and spaced apart from the first hole, the second hole defining a second hole axis and being structured to lockingly engage a head of a second bone anchor inserted therein such that a shaft of the second bone anchor extends along the second hole axis, the first and second hole axes defining a single plane and intersecting at a point on a side of the bone plate facing the second surface,
wherein the second section is connected to the first section such that the body is substantially L-shaped.

2. The bone plate of claim 1 , wherein the first section and the second section are integrally formed from a single piece of material.

3. The bone plate of claim 1 , wherein the first and second holes are both located in the second section.

4. The bone plate of claim 1 , wherein the first section is longer than the second section.

5. The bone plate of claim 1 , wherein the first and second longitudinal axes are angled at an obtuse angle relative to one another.

6. The bone plate of claim 5 , wherein the obtuse angle is between about 150.degree. and about 155.degree.

7. The bone plate of claim 1 , wherein the first and second longitudinal axes are angled at an acute angle relative to one another.

8. The bone plate of claim 1 , wherein the first and second longitudinal axes are angled relative to one another at an angle between about 85° and about 95°.

9. The bone plate of claim 1 , wherein the body further comprises a transition section connecting the first section to the second section and extending along a third longitudinal axis which is angled with respect to the first and second longitudinal axes.

10. The bone plate of claim 9 , wherein the third longitudinal axis is angled at an acute angle respect to at least one of the first and second longitudinal axes.

11. The bone plate of claim 9 , wherein the third longitudinal axis is angled at an obtuse angle with respect to at least one of the first and second longitudinal axes.

12. The bone plate of claim 9 , wherein the first surface of the transition section is substantially S-shaped.

13. The bone plate of claim 1 , wherein at least a portion of the second surface of the second section along the second longitudinal axis defines a radius of curvature.

14. The bone plate of claim 1 , wherein the first and second hole are both located in the same section.

15. The bone plate of claim 1 , wherein the first and second hole are configured such that the first and second axes define an acute angle at the point of intersection.

16. The bone plate of claim 1 , further comprising a third hole extending through the body and defining a third hole axis, the third hole being structured to lockingly engage a head of a bone anchor such that a shaft of the bone anchor extends along the third hole axis.

17. The bone plate of claim 16 , wherein the third hole axis intersects at least one of the first and second axes.

18. The bone plate of claim 16 , wherein the third hole is located in a section of the bone plate different from that of the first and second holes.

19. The bone plate of claim 16 , further comprising a transition section connecting the first section to the second section, the second section being in a plane different from that of the first section, the third hole being located in the transition section.

20. The bone plate of claim 16 , wherein at least one of the first, second and third holes is threaded to engage a threaded head of a bone fastener.

21. The bone plate of claim 1 , wherein at least one of the first and second holes is threaded to engage a threaded head of a bone fastener.

22. The bone plate of claim 1 , wherein the first and second hole axes define an acute angle at the point of intersection.

23. The bone plate of claim 22 , wherein the first and second axes define an angle of between about 30.degree. and about 45.degree. at the point of intersection.

24. The bone plate of claim 1 , wherein the plane defined by the first and second central axes lies at an angle relative to a plane bisecting the bone plate along the first longitudinal axis.

25. The bone plate of claim 24 , wherein the angle is between about 3.degree. and about 6.degree.

26. A bone plate, comprising:
a body having a first surface which, in an operative configuration, faces away from a bone on which the plate is to be mounted and a second surface, which in the operative configuration, faces the bone, the body including a first section extending along a first longitudinal axis and a second section extending along a second longitudinal axis angled with respect to the first longitudinal axis;
a first hole extending through the body from the first surface to the second surface and defining a first hole axis, the first hole being structured to lockingly engage a head of a first bone anchor inserted therein such that a shaft of the first bone anchor extends along the first hole axis;
and a second hole extending through the body and spaced apart from the first hole, the second hole defining a second hole axis and being structured to lockingly engage a head of a second bone anchor inserted therein such that a shaft of the second bone anchor extends along the second hole axis, the first and second hole axes defining a single plane and intersecting at a point on a side of the bone plate facing the second surface,
wherein the second section is connected to the first section such that the body is substantially T-shaped.

27. A system, comprising:
a bone plate, including:
a body having a first surface which, in an operative configuration, faces away from a bone on which the plate is to be mounted and a second surface, which in the operative configuration, faces the bone, the body including a first section extending along a first longitudinal axis and a second section extending along a second longitudinal axis angled with respect to the first longitudinal axis;
a first hole extending through the body from the first surface to the second surface and defining a first hole axis, and
a second hole extending through the body and spaced apart from the first hole, the second hole defining a second hole axis, the first and second hole axes defining a single plane and intersecting at a point on a side of the bone plate facing the second surface;
