Abstract

A suture crimp plate includes a body including a first bone-facing surface and a second opposing surface; a central hole extending through the body from the first surface to the second surface and sized and shaped to receive a bone fixation device; and a first suture hole extending through the body from the first surface to the second surface and sized and shaped to receive a suture therethrough. The first suture hole is open to the central hole via a first slot, a first deformable member being formed between the first suture hole and the central hole. When a bone fixation element is inserted into the central hole, the first deformable member is configured to be deflected away from a central longitudinal axis of the central hole and into the first suture hole to clamp the suture therein relative to the crimp plate.

First claim

What is claimed is:

1. A suture crimp plate, comprising:
a body including a first bone-facing surface and a second opposing surface;
a central hole extending through the body from the first surface to the second surface and sized and shaped to receive a bone fixation device; and
a first suture hole extending through the body from the first surface to the second surface and sized and shaped to receive a suture therethrough, the first suture hole being open to the central hole via a first slot, a first deformable member being formed between the first suture hole and the central hole,
wherein, when a bone fixation element is inserted into the central hole, the first deformable member is configured to be deflected away from a central longitudinal axis of the central hole and into the first suture hole to clamp the suture therein relative to the crimp plate.

2. The plate of claim 1 , further comprising:
a second suture hole extending through the body from the first surface to the second surface and sized and shaped to receive a suture therethrough, the second suture hole being open to the central hole via a second slot, a second deformable member being formed between the second suture hole and the central hole, wherein the second deformable member is movable away from a central longitudinal axis of the central hole and into the second suture hole to clamp the suture therein relative to the crimp plate.

3. The plate of claim 2 , wherein the first and second suture holes have a triangular profile.

4. The plate of claim 2 , wherein the first and second suture holes are positioned on opposing sides of the central hole.

5. The plate of claim 1 , wherein the first deformable member is formed of a shape-memory material.

6. The plate of claim 1 , wherein the central hole tapers in diameter from the first surface to the second surface.

7. The plate of claim 1 , wherein the central hole includes threading configured to mate with threading on an outer surface of the bone fixation element.

8. An implant system, comprising:
a crimp plate including:
a body including a first bone-facing surface and a second opposing surface;
a central hole extending through the body from the first surface to the second surface and sized and shaped to receive a bone fixation device; and
a first suture hole extending through the body from the first surface to the second surface and sized and shaped to receive a suture therethrough, the first suture hole being open to the central hole via a first slot, a first deformable member being formed between the first suture hole and the central hole;

a bone fixation element configured to be inserted through the central hole such that, when the bone fixation element is inserted through the central hole, the first deformable member is deflected away from a central longitudinal axis of the central hole and into the first suture hole to clamp the suture therein relative to the crimp plate; and
at least one suture configured to be passed through the first suture hole.

9. The system of claim 8 , wherein the crimp plate further includes a second suture hole extending through the body from the first surface to the second surface and sized and shaped to receive a suture therethrough, the second suture hole being open to the central hole via a second slot, a second deformable member being formed between the second suture hole and the central hole, wherein the second deformable member is movable away from a central longitudinal axis of the central hole and into the second suture hole to clamp the suture therein relative to the crimp plate.

10. The system of claim 9 , wherein the first and second suture holes are positioned on opposing sides of the central hole.

11. The system of claim 8 , wherein the bone fixation element includes a head and a shaft, a diameter of the head being larger than a diameter of the central hole.

12. The system of claim 8 , wherein the bone fixation element includes only a head, a diameter of the head being larger than a diameter of the central hole.

13. The system of claim 8 , wherein the central hole tapers in diameter from the first surface to the second surface.

14. The system of claim 8 , wherein the first deformable member is formed of a shape-memory material.

15. The system of claim 8 , wherein the at least one suture includes an anchor at a first end thereof, the anchor preventing a second end of the suture from passing through the suture hole when the suture is passed therethrough.

16. A method for treating a fracture, comprising:
positioning a suture about a target bone, a first end of the suture being pre-threaded through a first suture hole of a crimp plate, the crimp plate comprising:
a body including a first bone-facing surface and a second opposing surface;
a central hole extending through the body from the first surface to the second surface and sized and shaped to receive a bone fixation device; and
first and second suture holes extending through the body from the first surface to the second surface and sized and shaped to receive a suture therethrough, the first and second suture holes being open to the central hole via a first and second slots, respectively, a first deformable member being formed between the first suture hole and the central hole and a second deformable member being formed between the second suture hole and the central hole;

passing a second end of the suture through the second suture hole of the crimp plate;
sliding the crimp plate along the suture to a position adjacent the target bone; and
inserting a bone fixation member through the central hole such that the first and second deformable members are deflected away from a central longitudinal axis of the central hole and into the first and second suture holes to clamp the suture therein relative to the crimp plate.

17. The method of claim 16 , further comprising:
applying tension to the suture by hand to facilitate sliding of the crimp plate therealong.

18. The method of claim 16 , wherein the first and second deformable members are formed of a shape-memory material.

19. The method of claim 18 , further comprising:
inserting the bone fixation member only partially through the central hole such that the deformable members are deflected outwardly enough to crimp the suture in place within the first and second suture holes without being permanently deformed; and
repositioning the crimp plate along the target bone.

20. The method of claim 16 , wherein the first and second suture holes are positioned on opposing sides of the central hole.
