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 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 sized 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 deformable sleeve compresses 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 surgical cable has an effective outer diameter and the non-deformed configuration of the through opening of the deformable sleeve has an inner diameter smaller than the effective outer diameter of the surgical cable.

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

5. 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.

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

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

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

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

a surgical cable; and

a connector comprising;

a body;

a deformable sleeve associated with 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; and

sleeve support portions of the body supporting the deformable sleeve and laterally spaced from the actuator lower portion to permit the actuator lower portion to bend the deformable sleeve and the surgical cable therein into lateral spaces between the sleeve support portions and the actuator lower portion as the actuator is shifted in the longitudinal direction.

10. The apparatus of claim 9 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.

11. The apparatus of claim 9 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.

12. The apparatus of claim 9 wherein the actuator lower end 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.

13. The apparatus of claim 9 wherein the body includes a throughbore that receives the actuator and the throughbore includes a laterally enlarged undercut separating the sleeve support portions.

14. The apparatus of claim 9 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.

15. The apparatus of claim 9 wherein the surgical cable is tubular.

16. A bone plate system comprising a bone plate including the apparatus of claim 9 and a plurality of bone screws, the bone plate including a bone plate body having a plurality of throughbores for receiving the bone screws.

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

positioning a surgical cable about bone portions;

advancing the surgical cable through a connector;

compressing elements of the surgical cable together as the surgical cable is advanced into the connector; and

securing the surgical cable to the connector.

18. The method of claim 17 wherein advancing the surgical cable through a connector includes advancing the surgical cable through an opening of a deformable sleeve of the connector that is smaller than an effective diameter of the surgical cable to compress the elements of the surgical cable together.

19. The method of claim 17 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 17 wherein advancing the surgical cable through the connector includes advancing the surgical cable through a sleeve of the connector and securing the surgical cable to the connector includes operating an actuator of the connector to deform the sleeve and crimp the surgical cable therein.

21. The method of claim 17 wherein advancing the surgical cable through the connector includes advancing the surgical cable into a sleeve of the connector and securing the surgical cable to the connector includes shifting a lower portion of the actuator in a longitudinal direction and deforming the 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 17 wherein advancing the surgical cable through the connector includes advancing the surgical cable through a sleeve of the connector and 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 sleeve into a recess of the actuator.

23. The method of claim 17 wherein securing the surgical cable to the connector includes shifting an annular wall of an actuator of the connector to deform a sleeve extending about the surgical cable.

24. The method of claim 17 further comprising driving bone screws through through bores of a bone plate associated with the connector and into the bone portions.
