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 (19)

1. A method for binding a cable about a fractured bone to stabilize a fracture, the method comprising:

inserting around a fractured bone to be stabilized a cable including an enlarged first end;

inserting the first end of the cable into a slot of a body portion of a binding device via a distal opening of the slot sized to receive the enlarged end so that the cable extends out of a proximal opening of the slot, the proximal opening of the slot being sized to prevent the passage of the first end of the cable therethrough, 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 side opening extending between the distal opening and the proximal opening;

drawing the cable proximally through the slot until the first end of the cable contacts a wall surrounding the proximal opening;

inserting a second end of the cable into a bore extending between a distal bore opening formed in the first side surface and a proximal bore opening opening into a distal length of the slot, the distal bore opening being axially separated from the outer surface;

drawing the second end of the cable proximally out of the proximal bore opening to draw the cable around the bone until a desired tension has been placed on the cable; and

inserting a locking element into a locking position in a locking element channel extending from a proximal locking channel opening formed in the second side surface to a distal end opening into the bore, a distal end of the locking element extending into the bore to engage a portion of the cable received therein and lock the cable in a desired position within the bore, the proximal opening of the slot being dimensioned so that, when both the enlarged end and a proximal length of the cable are simultaneously positioned within the slot, the second end of the cable is insertable through the slot and out of the proximal opening.

2. The method of claim 1 , wherein a proximal end of the slot is offset toward a bone facing side of the of the device relative to the bore.

3. The method of claim 2 , wherein the proximal end of the slot is offset toward the bone facing side of the device relative to the bore by a distance at least equal to a profile of the enlarged distal end of the cable to be used with the device.

4. The method of claim 3 , wherein the slot slopes toward an outer side of the device opposite the bone facing side thereof toward a distal end of the slot.

5. The method of claim 4 , wherein the slot extends substantially in a common plane with an axis of the bore.

6. The method of claim 1 , wherein the bore is offset laterally from the slot.

7. The method of claim 1 , wherein the locking element is a set screw.

8. The method of claim 7 , wherein a proximal portion of the locking element channel includes a threading corresponding to a threading of the set screw.

9. The method of claim 1 , further comprising:

moving a mating element to abut a distal abutting surface thereof to a proximal abutting surface of the binding device such that a first channel of the mating element is aligned with the bore and a second channel of the mating element is aligned with the locking element channel when the locking element is in a desired position.

10. The method of claim 9 , 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.

11. The method of claim 9 , wherein the mating element includes a proximal abutting surface for abutting a distal end of a tensioning device.

12. The method of claim 1 , wherein the locking element comprises one of an interference fit plug and a pin in combination with a crushable section of the locking element channel, crushing of the crushable section locking the pin in a desired position within the locking element channel.
