Abstract

A suture connection system and method includes a suture connector having a body configured to be inserted into a hole in a bone plate, the body being threaded to secure the suture connector in to the bone plate. At least one recess extends inwardly from a sidewall of the suture connector to define a proximal engagement portion and a through hole configured to receive a suture extends through the proximal engagement portion and is open to the recess. A driver includes an elongate rod and an engagement element coupled to the distal end of the rod, the engagement element having at least one prong configured to engage the proximal engagement portion to insert the suture connector into the bone plate hole.

First claim

What is claimed is:

1. A suture connection system, comprising:
a suture connector, comprising:
a connector body configured to be inserted into a hole in a bone plate, the connector body having a proximal end, a distal end, a length extending between the proximal end and the distal end substantially corresponding to a thickness of the bone plate, and a sidewall threaded to secure the suture connector to the bone plate;
the connector body including a first recess extending inwardly from the sidewall to define a first side-face and
a through hole, configured to receive a suture, the through hole extending through the first side-face and open to the recess; and

a driver including an elongated rod extending from a proximal end to a distal end along a longitudinal axis of the driver and an engagement element coupled to the distal end of the rod, the engagement element having a first prong configured to engage the first side-face.

2. The system of claim 1 , wherein the connector body includes a second recess extending inwardly from the sidewall to define a second side-face and wherein the engagement element includes a second prongs configured to engage the second side-face.

3. The system of claim 2 , wherein the first and second prongs are separated from one another by a distance selected so that the first prong may be positioned in the first recess while the second prongs is positioned in the second recess to engage the first and second side.

4. The system of claim 1 , wherein the first prong includes a cutout.

5. The system of claim 4 , wherein the first cutout extends from a distal face of the first prong to a rounded proximal cutout edge of the first prong, the proximal cutout edge of the first prong aligning with a proximal edge of the through hole so that no portion of the first prong obstructs the through hole.

6. The system of claim 1 , wherein the suture connector is sized and shaped to sit flush within the bone plate hole such that no portion of the suture connector extends past an upper surface or a lower surface of the bone plate.

7. A bone plate assembly, comprising:
a plate having an upper surface, a lower surface and a plurality of holes extending through the plate form the upper surface to the lower surface; and
at least one suture connector positioned in one of the holes of the plate, the suture connector comprising:
a body having a proximal end, a distal end, a sidewall, a first recess extending inwardly from the sidewall, and a through hole open to the first recess, the body including a threading to threadedly engage the hole of the plate, and

a driver extending from a proximal end to a distal end including an engagement element, the engagement element having a first prong configured to engage a first side-face of the first recess.

8. The assembly of claim 7 , wherein the body includes a second recess extending inwardly from the sidewall to define a second side-face, and wherein the through hole is open to the second recess and wherein the engagement element includes a second prongs.

9. The assembly of claim 7 , wherein the first prong includes a cutout.

10. The assembly of claim 9 , wherein the cutout extends from a distal prong face of the first prone to a rounded proximal cutout edge of the first prong, the proximal cutout edge of the first prong aligning with a proximal edge of the through hole so that, when the first prong engages the first side-face, no portion of the first prong obstructs the through hole.

11. The assembly of claim 7 , wherein each of the holes is one of a locking hole and a variable angle locking holes.

12. The assembly of claim 7 , wherein the suture connector is sized and shaped to sit flush within the bone plate hole such that no portion of the suture connector extends past an upper surface or a lower surface of the bone plate.

13. A method for connecting a suture to a bone, comprising:
securing a bone plate to the bone, the bone plate having a plurality of holes extending through the plate from an upper surface to a lower surface;
inserting a first suture into a suture connector, the first suture connector comprising:
a body having a proximal end, a distal end, a sidewall, a first recess extending inwardly from the first sidewall, and a through hole open to the first recess, the body including a threading to threadedly engage a first one of the holes of the plate,

positioning the first suture connector in the first holes, and
using a driver, rotating the first suture connector until the first suture connector is threadedly inserted into the first hole, the driver including an elongated rod and an engagement element coupled to the distal end of the rod, the engagement element including a first prong configured to engage the first side-face.

14. The method of claim 13 , wherein rotation of the driver transmits torsional loads from the driver to the first suture connector to rotate the first suture connector.

15. The method of claim 13 , further comprising:
removing the first suture connector from the first hole;
repositioning the first suture connector at a second one of the plurality of holes; and
inserting the first suture connector, using the driver, into the second one of the plurality of holes.

16. The method of claim 13 , wherein the body includes a second recess extending inwardly from the sidewall, and wherein the through hole is open to the second recess, wherein the engagement element includes a second prongs, the second prongs being configured to engage the second side-face.

17. The method of claim 13 , wherein the first prong includes a cutout, the cutout extending from a distal prong face of the first prong to a rounded proximal cutout edge of the first prong, the proximal cutout edge of the first prong aligning with a proximal edge of the through hole so that no portion of the first prong obstructs the through hole.
