Abstract

Syndesmosis fixation assemblies, systems, and methods thereof. A syndesmosis fixation assembly includes a suture retaining portion having a plurality of suture openings formed therein and a suture securing portion rotatably connected to the suture retaining portion. The suture securing portion is movable between a first position wherein a suture is moveable within the suture retaining portion and a second position wherein the suture is frictionally secured within the suture retaining portion. A bone insertion portion has a distal bone insertion end adapted for insertion into a bone, a proximal bone insertion end connected to the suture retaining portion, and a central longitudinal axis extending between the distal bone insertion end and the proximal bone insertion end.

First claim

What is claimed is:

1. A syndesmosis fixation assembly comprising:
a suture retaining portion having a plurality of fingers, each finger separated by a longitudinal gap;
a suture securing portion configured to be received in the suture retaining portion, wherein the suture securing portion has an anchor with anchor legs, each anchor leg configured to extend into one of the longitudinal gaps; and
a bone insertion portion having:
a distal bone insertion end adapted for insertion into a bone;
a proximal bone insertion end extending distally from the suture retaining portion; and
a central longitudinal axis extending between the distal bone insertion end and the proximal bone insertion end.

2. The syndesmosis fixation assembly according to claim 1 , wherein a suture is configured to be inserted into suture retaining portion such that each end of the suture extends outwardly from one of the longitudinal gaps.

3. The syndesmosis fixation assembly according to claim 2 , wherein the suture retaining portion further includes a set screw configured to be received into the suture securing portion.

4. The syndesmosis fixation assembly according to claim 3 , wherein the set screw has a blunt distal tip.

5. The syndesmosis fixation assembly according to claim 4 , wherein the distal bone insertion end is blunt.

6. The syndesmosis fixation assembly according to claim 3 , wherein the set screw has threads that mate with threads an internal thread in suture retaining portion.

7. The syndesmosis fixation assembly according to claim 2 , wherein the set screw is configured to advance into suture retaining portion to cause the anchor to frictionally engage the suture.

8. The syndesmosis fixation assembly according to claim 7 , wherein the set screw is configured to splay each anchor leg out of one of the longitudinal gaps as set screw is advanced into the suture retaining portion.

9. The syndesmosis fixation assembly according to claim 1 , wherein the suture retaining portion and the bone insertion portion contain external ribbing.

10. The syndesmosis fixation assembly according to claim 1 , wherein the anchor is a spring anchor with a body portion and the anchor legs extend outwardly from the body portion.
