Extra joint stabilization construct
The disclosure provides devices and methods of use pertaining to extra joint stabilization. Embodiments include a number of suture returning and locking anchors that feature both a suture return element and a suture locking feature that employs an interference fit between a flexible synthetic strand, a receiver of the anchor, and a set screw, where the receiver and the set screw each have a number of gradual, opposing tapers to facilitate gradual proximal-to-distal gripping and releasing of the flexible strand to achieve an optimal locking force while preventing severing of the flexible strand. Embodiments also include a counter-torque anchor driver configured to resist torsional forces generated during and translated to the anchor during set-screw insertion. Further embodiments include extra joint reinforcement, stabilization, and attachment constructs formed using the disclosed devices. Other embodiments are disclosed.
1. A method of at least one of reducing and stabilizing a joint, the method comprising:
inserting a first anchor into a first bone;
inserting a second anchor into a second bone adjacent the first bone with a joint there between;
routing a flexible strand connected to the first anchor into an internal passage at the proximal end of the second anchor and around a return feature;
tensioning the flexible strand to reduce or stabilize the joint; and
moving a locking member within the second anchor to lock the flexible strand to the second anchor.
2. The method of claim 1 , wherein the routing the flexible strand into the internal passage at the proximal end of the second anchor and around the return feature includes exiting the flexible strand from the internal passage out of the proximal end of the second anchor.
3. The method of claim 1 , wherein the routing the flexible strand into the internal passage at the proximal end of the second anchor and around the return feature includes exiting the flexible strand from the internal passage out of a side aperture formed through the second anchor.
4. The method of claim 1 , wherein the routing the flexible strand into the internal passage at the proximal end of the second anchor and around the return feature includes exiting the flexible strand from the internal passage out of a distal end of the second anchor.
5. The method of claim 1 , wherein the locking the suture to the flexible strand includes a reversible configuration so as to further allow unlocking the flexible strand relative to the second anchor.
6. The method of claim 1 , wherein the locking the suture to the flexible strand includes applying a screw.
7. The method of claim 1 , wherein the locking member locks the flexible strand to the second anchor by pressing the flexible strand against the internal passage.
8. The method of claim 1 , wherein the return feature is formed as a single piece with the proximal end.
9. A method of at least one of reducing and stabilizing a joint, the method comprising:
inserting a first anchor into a first bone;
inserting a second anchor into a second bone adjacent the first bone with a joint there between;
routing a flexible strand connected to the first anchor into an internal passage at the proximal end of the second anchor and around a return feature;
tensioning the flexible strand to reduce or stabilize the joint; and
locking the flexible strand to the second anchor by pressing the flexible strand against the internal passage.
10. The method of claim 9 , wherein the routing the flexible strand into the internal passage at the proximal end of the second anchor and around the return feature includes exiting the flexible strand from the internal passage out of the proximal end of the second anchor.
11. The method of claim 9 , wherein the routing the flexible strand into the internal passage at the proximal end of the second anchor and around the return feature includes exiting the flexible strand from the internal passage out of a side aperture formed through the second anchor.
12. The method of claim 9 , wherein the routing the flexible strand into the internal passage at the proximal end of the second anchor and around the return feature includes exiting the flexible strand from the internal passage out of a distal end of the second anchor.
13. The method of claim 9 , wherein the locking the suture to the flexible strand includes a reversible configuration so as to further allow unlocking the flexible strand relative to the second anchor.
14. The method of claim 9 , wherein the locking the suture to the flexible strand includes applying a screw.
15. A method of at least one of reducing and stabilizing a joint, the method comprising:
inserting a first anchor into a first bone;
inserting a second anchor into a second bone adjacent the first bone with a joint there between;
routing a flexible strand connected to the first anchor into an internal passage at the proximal end of the second anchor and around a return feature formed as a single piece with the proximal end;
tensioning the flexible strand to reduce or stabilize the joint; and
locking the flexible strand to the second anchor.
16. The method of claim 15 , wherein the routing the flexible strand into the internal passage at the proximal end of the second anchor and around the return feature includes exiting the flexible strand from the internal passage out of the proximal end of the second anchor.
17. The method of claim 15 , wherein routing the flexible strand into the internal passage at the proximal end of the second anchor and around the return feature includes exiting the flexible strand from the internal passage out of a side aperture formed through the second anchor.
18. The method of claim 15 , wherein the routing the flexible strand into the internal passage at the proximal end of the second anchor and around the return feature includes exiting the flexible strand from the internal passage out of a distal end of the second anchor.
19. The method of claim 15 , wherein the locking the suture to the flexible strand includes a reversible configuration so as to further allow unlocking the flexible strand relative to the second anchor.
20. The method of claim 15 , wherein the locking the suture to the flexible strand includes applying a screw.
