Abstract

The present disclosure includes a method for reducing a bone fracture and an apparatus such as a cable button for use with a bone plate, the cable button including cable button threads, a plurality of cable button apertures, a hex socket, and a hex opening. The present disclosure also includes a method for reducing a bone fracture and an apparatus such as a cable button for use with a bone plate, the cable button including a plurality of legs, where a leg includes a protrusion, where the protrusion engages the bone plate, and the cable button defines at least one cable button aperture.

Claims

1. A cable button for use with a bone plate and a cerclage wire, the bone plate including at least one bone plate aperture including bone plate threads, the cable button comprising:

a body defining a longitudinal axis, the body defining cable button threads extending along a first portion of the body, the body defining a plurality of cable button apertures extending along a second portion of the body, whereby at least one of the plurality of cable button apertures is sized to accommodate passage of the cerclage wire.

2. The cable button of claim 1, wherein the plurality of cable apertures is selected from the group consisting of 1, 2, 3, 4, 5, and 6 apertures.

3. The cable button of claim 1, wherein the body defines a cavity in communication with the plurality of cable apertures.

4. The cable button of claim 3, wherein the body defines a polygon opening and a polygon socket, the cavity in communication with the polygon opening, and the polygon socket.

5. The cable button of claim 1, wherein the body defines a polygon socket located along the longitudinal axis.

6. The cable button of claim 5, wherein the body is configured to screw on the bone plate along the longitudinal axis.

7. The cable button of claim 6 wherein the bone plate defines a bone plate height, wherein the first portion of the body substantially equals the bone plate height.

8. A method of reducing a bone fracture in a bone, the method comprising the steps of:

providing a bone plate, a cable button, and a cerclage wire, the bone plate defining at least one bone plate aperture, the cable button defining at least one cable button aperture,

securing the cable button to the bone plate,

positioning the cerclage wire around the bone and the bone plate,

guiding the cerclage wire through at least one of the cable button apertures, and

securing the cerclage wire to the bone to compress the bone fracture.

9. The method of claim 8, wherein the bone plate includes bone plate threading, and the cable button includes cable button threading, said step of securing the cable button to the bone plate comprising the step of threading the cable button to the bone plate.

10. A bone fracture reduction apparatus comprising:

a bone plate defining at least one bone plate aperture,

a cable button configured to secure to the bone plate, the cable button defining a plurality of cable button apertures, and

a cerclage wire at least partially located within at least one of the plurality of cable button apertures.

11. The apparatus of claim 10, wherein the bone plate including bone plate threading adjacent to the at least one bone plate aperture.

12. The apparatus of claim 11, wherein the cable button defines cable button threading configured to engage the bone plate threading.

13. The apparatus of claim 10, wherein the cable button defines a polygon opening and a polygon socket.

14. The apparatus of claim 10, wherein the bone plate defines a bone contacting surface and a opposite surface, wherein the distance between the proximal and opposite surfaces defines a bone plate height, wherein the cable button defines a cable button height selected from the group consisting of less than, greater than, and equal to the bone plate height, wherein the plurality of cable button apertures are exterior to the bone plate.

15. A bone fracture reduction apparatus comprising:

a bone plate defining at least one bone plate aperture,

a cerclage wire configured to secure to the bone plate, and

means for modifying the bone plate to allow for securing the cerclage wire to the bone plate, the means for modifying securable to the bone plate.

16. The apparatus of claim 15, wherein means for modifying defines a plurality of cable button apertures.

17. A cable button for use with a bone plate, the bone plate defining at least one bone plate aperture, the bone plate including a bone contacting surface and an opposite surface, the cable button comprising:

a body including a plurality of legs, wherein at least one leg includes a projection, wherein the projection is configured to engage the bone plate, the body defining at least one cable button aperture, wherein the at least one cable button aperture is free to rotate relative to the bone plate.

18. The cable button of claim 17, wherein each of the plurality of legs include at least one projection, wherein the bone plate including bone plate threads, the projection configured to engage the bone plate threads.

19. The cable button of claim 17, wherein the distance between the bone contacting surface and opposite surface defines a bone plate height, wherein the cable button defines a cable button height greater than the bone plate height, wherein at least a portion of the at least one cable button aperture is adjacent of the bone plate height.

20. The cable button of claim 17, wherein the body defines a depression to assist in pushing the body into the at least one bone plate aperture.
