Abstract

A device for binding a cable about a fractured bone to stabilize a fracture includes a slot including a distal opening sized to receive an enlarged end of a cable and a proximal opening sized to permit the cable to slide therethrough while preventing the enlarged end from passing therethough and a bore sized to slidably receive the cable, the bore extending to a proximal opening in combination with a locking element channel extending to a distal end opening into the bore and a locking element movable into a locking position in which a distal end of the locking element extends into the bore to engage a portion of the cable received therein and lock the cable in a desired position within the bore.

Claims

1-14. -14. (canceled)

15. A device for binding a cable about a fractured bone to stabilize a fracture, comprising:

a body portion having a slot, the body portion having a bone facing surface, an outer surface opposite the bone facing surface and first and second side surfaces extending therebetween, the first side surface being opposite the second side surface, the slot including a distal opening sized to receive an enlarged end of a cable and a proximal opening sized to permit the cable to slide therethrough while preventing the enlarged end from passing therethrough and a side opening extending between the distal opening and the proximal opening;

a bore extending between a proximal bore opening in the first side surface and a distal bore opening in the second side surface, the bore being sized to slidably receive the cable;

a locking element channel extending between a proximal locking channel opening formed in the first side surface and a distal locking channel opening into a distal portion of the bore; and

a locking element movable into a locking position in the locking element channel in which a distal end of the locking element extends into the bore to engage a portion of the cable received therein and lock the cable in a desired position within the bore.

16. The device of claim 15, wherein the bore is substantially parallel to the slot.

17. The device of claim 15, wherein the channel is offset laterally from the bore.

18. The device of claim 15, wherein the slot includes a lip extending from the distal opening substantially around a perimeter thereof.

19. The device of claim 15, wherein the locking element is a set screw

20. The device of claim 15, wherein a proximal portion of the locking element channel includes a threading corresponding to a threading of the set screw.

21. The device of claim 15, wherein the side opening is located on the outer surface of the body portion.

22. The device of claim 15, wherein the slot extends substantially parallel to the bone facing surface.

23. The device of claim 15, further comprising a mating element including:

a distal abutting surface for abutting a proximal abutting surface of the device;

a first channel which, when in a desired position, is aligned with the with the bore; and

a second channel which, when in a desired position, is aligned with the locking element channel.

24. The device of claim 21, wherein the second channel includes a proximal portion and a distal portion, the proximal portion being angled relative to the distal portion, which is angled toward the first channel.

25. The device of claim 22, wherein the mating element includes a proximal abutting surface for abutting a distal end of a tensioning device.

26. The device of claim 15, wherein the distal locking channel opening is proximally spaced from a distal end of the body and distally spaced from a proximal end of the body.
