Abstract

In accordance with one aspect of the present disclosure, an apparatus for securing bone portions is provided that includes a surgical cable having a plurality of elongate elements and a connector. The connector includes a body and a deformable sleeve associated with the body and having a through opening for receiving the surgical cable. The through opening of the surgical cable has a non-deformed configuration sized to compress the elements of the surgical cable together with the surgical cable extending in the sleeve through opening. An actuator is connected to the body and is operable to deform the sleeve and further compress the compressed elements of the surgical cable therein to secure the surgical cable relative to the body.

Claims

1. An apparatus for securing bone portions, the apparatus comprising:

a surgical cable having an effective outer diameter and including a plurality of elongate elements; and

a connector comprising;

a body;

a deformable sleeve associated with the body and having a through opening for receiving the surgical cable, the through opening having a non-deformed configuration wherein the through opening has an initial inner diameter smaller than the effective outer diameter of the surgical cable to compress the elements of the surgical cable together with the surgical cable extending in the sleeve through opening; and

an actuator connected to the body and operable to deform the sleeve and further compress the compressed elements of the surgical cable therein to secure the surgical cable relative to the body.

2. The apparatus of claim 1 wherein the initial inner diameter of the deformable sleeve through opening is sized to compress the surgical cable as the surgical cable is advanced into the through opening from a free state configuration to a near solid state configuration.

3. The apparatus of claim 1 wherein the inner diameter of the deformable sleeve through opening is seventy percent or less than the effective outer diameter of the surgical cable.

4. A bone plate system comprising a plurality of bone screws and a bone plate that includes the apparatus of claim 1, the bone plate including a bone plate body having a plurality of throughbores for receiving the bone screws.

5. The bone plate of claim 4 wherein the bone plate body and the connector body are monolithically formed from a single piece of material.

6. The apparatus of claim 1 wherein the elongate elements of the surgical cable each include a plurality of elongate monolithic strands.

7. The apparatus of claim 1 wherein the elongate elements of the surgical cable comprise elongate monolithic strands of metallic or polymer material.

8. The apparatus of claim 1 wherein the deformable sleeve has opposite ends and a tubular side wall extending from one end of the deformable sleeve to the other end.

9. The apparatus of claim 1 wherein the surgical cable has a free state configuration wherein the elongate elements surround an interior void of the surgical cable and the surgical cable has gaps separating the elongate elements from each other, the surgical cable further having a solid state configuration wherein the elongate elements contact each other and the gaps are closed.

10. An apparatus for securing bone portions, the apparatus comprising:

a surgical cable; and

a connector comprising;

a body having an upper surface and a lower surface;

a throughbore of the body extending laterally through the body;

a deformable sleeve in the throughbore of the body and having a through opening for receiving the surgical cable;

an actuator connected to the body and having a lower portion adapted to be shifted in a longitudinal direction transverse to the surgical cable between unlocked and locked positions to contact the deformable sleeve and deform the surgical cable extending therein;

a lower opening of the body that opens to the lower surface of the body and is in communication with the throughbore of the body; and

sleeve support portions of the body on opposite sides of the lower opening from each other, the sleeve support portions supporting the deformable sleeve and being laterally outwardly spaced from the actuator lower portion to permit the actuator lower portion to bend at least a portion of the deformable sleeve and the surgical cable therein into the lower opening and the lateral spaces between the sleeve support portions and the actuator lower portion as the actuator is shifted downward in the longitudinal direction.

11. The apparatus of claim 10 wherein the actuator lower portion includes a recess adapted to permit a portion of the deformable sleeve to deform into the recess as the actuator lower portion shifts between the unlocked and locked positions thereof.

12. The apparatus of claim 10 wherein the actuator lower portion includes an annular wall adapted to contact and deform the deformable sleeve as the actuator lower portion is driven between unlocked and locked positions.

13. The apparatus of claim 10 wherein the actuator lower portion contacts the deformable sleeve intermediate the sleeve support portions of the body and forms neckdown portions of the deformable sleeve that extend through the lateral spaces between the sleeve support portions and the actuator lower portion as the actuator lower portion shifts to the locked position thereof.

14. The apparatus of claim 10 wherein the body includes a second throughbore that receives the actuator and the lower opening separating the sleeve support portions is a lower portion of the second throughbore.

15. The apparatus of claim 10 wherein the surgical cable includes a plurality of elements each comprising a plurality of strands and the through opening of the deformable sleeve is sized to compress the elements of the surgical cable together with the surgical cable extending in the sleeve through opening.

16. The apparatus of claim 10 wherein the surgical cable is tubular.

17. A bone plate system comprising a bone plate including the apparatus of claim 10 and a plurality of bone screws, the bone plate including a bone plate body having a plurality of throughbores for receiving the bone screws.

18. A method of securing bone portions, the method comprising:

positioning a surgical cable about bone portions, the surgical cable having an effective outer diameter and including a plurality of elongate elements;

advancing the surgical cable into a through opening of a deformable sleeve of a connector, the through opening having a non-deformed configuration wherein the through opening has an initial inner diameter smaller than the effective outer diameter of the cable;

compressing elements of the surgical cable together using the smaller initial inner diameter of the through opening of the deformable sleeve of the connector as the surgical cable is advanced into the deformable sleeve of the connector; and

securing the surgical cable to the connector.

19. The method of claim 18 wherein compressing the elements of the surgical cable together includes compressing the elements from a free state configuration to a near solid state configuration.

20. The method of claim 18 wherein securing the surgical cable to the connector includes operating an actuator of the connector to deform the deformable sleeve and crimp the surgical cable therein.

21. The method of claim 18 wherein securing the surgical cable to the connector includes shifting a lower portion of an actuator of the connector in a longitudinal direction and deforming the deformable sleeve and surgical cable therein into lateral spaces between the actuator lower portion and sleeve supporting portions of the connector.

22. The method of claim 18 wherein securing the surgical cable to the connector includes shifting an actuator of the connector between unlocked and locked positions and deforming a portion of the deformable sleeve into a recess of the actuator.

23. The method of claim 18 wherein securing the surgical cable to the connector includes shifting an annular wall of an actuator of the connector to deform the deformable sleeve extending about the surgical cable.

24. The method of claim 18 further comprising driving bone screws through bores of a bone plate associated with the connector and into the bone portions.
