Abstract

According to some embodiments, an implant for correcting a deformity in or near a joint of a subject includes an implant body having an internal lumen, a suture side hole or window extending through a wall of the implant body and providing access to the internal lumen through an exterior of the implant body, a tension assembly comprising a first bone anchor and a second bone anchor, wherein the first and second bone anchors are configured to be placed on opposite sides of the implant body, and an adjustable suture loop coupling the first bone anchor to the second bone anchor, wherein at least a portion of the at least one adjustable suture loop is positioned within the internal lumen of the implant body.

Claims

1. An implant for correcting a deformity in or near a joint of a subject, comprising:

an implant body comprising an internal lumen extending from a first end to a second end of the implant body, the implant body having a wall that defines the internal lumen, wherein the implant body is rigid;

wherein the implant body comprises a suture side hole extending through the wall of the implant body, the suture side hole being positioned between the first and second ends of the implant body, and wherein the suture side hole provides access to the internal lumen from an exterior of the implant body; and

a tension assembly comprising a first bone anchor and a second bone anchor, wherein the first and second bone anchors are positioned on opposite sides of the implant body;

the tension assembly further comprising at least one adjustable suture loop coupling the first bone anchor to the second bone anchor, wherein at least a portion of the at least one adjustable suture loop is positioned within the internal lumen of the implant body;

wherein the at least one adjustable suture loop comprises at least one suture tail that extends through the suture side hole and to an exterior of the implant body, wherein, upon deployment and fixation of the first and second bone anchors within bone bores of a subject and upon the application of tension to the at least one suture tail in a direction away from the implant body, a tension between the first and second bone anchors is increased.

2. The implant of claim 1, further comprising a positioning element located along the implant body, the positioning element being configured to facilitate adjustment of the implant body within corresponding bone bores of a subject once the implant has been located therein,

wherein the at least one adjustable suture loop comprises at least one knotless construct, the at least one knotless construct comprising a portion of the at least one adjustable suture loop routed through an interior of a section of the at least one adjustable suture loop;

wherein each of the first and second bone anchors comprises an eyelet, wherein a portion of the at least one adjustable suture loop traverses through the eyelets of the first and second bone anchors to secure the at least one adjustable suture loop to the first and second bone anchors;

wherein a cross-sectional shape of the implant body is polygonal; and

wherein the joint of the subject comprises a toe, and the deformity comprises hammer toe.

3. The implant of claim 1,

wherein the at least one adjustable suture loop comprises at least one knotless construct, the at least one knotless construct comprising a portion of the at least one adjustable suture loop routed through an interior of a section of the at least one adjustable suture loop;

and

wherein each of the first and second bone anchors comprises a securement feature, wherein a portion of the at least one adjustable suture loop traverses through the securement features of the first and second bone anchors to secure the at least one adjustable suture loop to the first and second bone anchors.

4. The implant of claim 1, further comprising a sliding knot formed by the at least one adjustable suture loop, wherein the sliding knot is maintained within the interior lumen of the implant body.

5. The implant of claim 4, wherein an outer dimension of the sliding knot is greater than the suture side hole.

6. The implant of claim 1, wherein each of the first and second bone anchors comprises a plurality of deflectable fingers configured to engage bone at an implantation site.

7. The implant of claim 1, wherein the at least one adjustable suture loop comprises at least one knotless construct, wherein the at least one knotless construct comprises a portion of the at least one adjustable suture loop routed through an interior of a section of the at least one adjustable suture loop.

8. The implant of claim 1, wherein the implant body comprises a hexagonal or other polygonal cross-sectional shape.

9. The implant of claim 1, wherein the implant body comprises at least one bend or angle along a length of the implant body.

10. An implant for correcting a deformity in or near a joint of a subject, comprising:

an implant body comprising an internal lumen, wherein the implant body is rigid;

a first bone anchor and a second bone anchor, wherein the first and second bone anchors are configured to be placed on opposite sides of the implant body when the implant is assembled for use; and

at least one adjustable suture loop coupling the first bone anchor to the second bone anchor, wherein at least a portion of the at least one adjustable suture loop is positioned within the internal lumen of the implant body;

wherein the at least one adjustable suture loop comprises at least one suture tail that extends through a side hole of the implant body and to an exterior of the implant body, wherein the at least one adjustable suture loop is configured to maintain tension between the first and second bone anchors upon implantation.

11. The implant of claim 10, further comprising a sliding knot formed by the at least one adjustable suture loop, wherein the sliding knot is maintained within the interior lumen of the implant body.

12. The implant of claim 11, wherein an outer dimension of the sliding knot is greater than the side hole.

13. The implant of claim 10, wherein the at least one adjustable suture loop comprises at least one knotless construct, wherein the at least one knotless construct comprises a portion of the at least one adjustable suture loop routed through an interior of a section of the at least one adjustable suture loop.

14. The implant of claim 10, wherein the implant body comprises at least one bend or angle along a length of the implant body.

15. The implant of claim 10,

wherein the at least one adjustable suture loop comprises at least one knotless construct, the at least one knotless construct comprising a portion of the at least one adjustable suture loop routed through an interior of a section of the at least one adjustable suture loop;

and

wherein each of the first and second bone anchors comprises an eyelet, wherein a portion of the at least one adjustable suture loop traverses through the eyelets of the first and second bone anchors to secure the at least one adjustable suture loop to the first and second bone anchors.

16. An implant for correcting a deformity in or near a joint of a subject, comprising:

an implant body comprising an internal lumen, wherein the implant body is rigid;

a first bone anchor and a second bone anchor, wherein the first and second bone anchors are configured to be placed on opposite sides of the implant body; and

at least one adjustable suture loop coupling the first bone anchor to the second bone anchor, wherein at least a portion of the at least one adjustable suture loop is configured to extend within the internal lumen of the implant body;

wherein the at least one adjustable suture loop comprises at least one tail that extends through a side opening of the implant body; and

wherein the at least one adjustable suture loop is configured to maintain tension between the first and second bone anchors upon implantation.

17. The implant of claim 16,

wherein the at least one adjustable suture loop comprises at least one knotless construct, the at least one knotless construct comprising a portion of the at least one adjustable suture loop routed through an interior of a section of the at least one adjustable suture loop;
