Abstract

A method includes forming a bone tunnel through a first bone and a second bone and inserting a flexible construct through the bone tunnel. The flexible construct includes a first anchoring element and a second anchoring element coupled by at least one flexible strand defining an adjustable loop. The at least one flexible strand includes a first end extending from the first anchoring element in an opposite direction from the adjustable loop. A length of the adjustable loop is adjusted to position the first bone and the second bone in a selected spacing. The first end of the at least one flexible strand is coupled to a tissue section using a third anchoring element.

First claim

What is claimed is:

1. An anchoring system, comprising:
an anchoring construct, including:
a first anchor having a body defining a first side and a second side;
a second anchor; and
a first flexible strand defining an adjustable loop extending between the first side of the first anchor and the second anchor, the first flexible strand having a first end extending from the second side of the first anchor; and

a tissue anchor coupled the first end of the first flexible strand and configured to couple the first end of the first flexible strand to a first tissue section, wherein the tissue anchor and the first end of the first flexible strand are configured to maintain the adjustable loop at a predetermined length between the first anchor and the second anchor.

2. The system of claim 1 , wherein the first end of the first flexible strand is configured to be coupled to the tissue section by an interference fit.

3. The system of claim 2 , wherein the tissue anchor comprises a body defining a channel, and wherein the first flexible strand extends at least partially into the channel.

4. The system of claim 3 , wherein the first flexible strand defines a loop about a portion of the body of the tissue anchor.

5. The system of claim 1 , comprising a bone plate having a body extending between a bone facing surface and an opposing surface, the body defining a hole therethrough, wherein the first anchor and the first flexible strand of the anchoring construct are sized and configured for insertion through the hole defined in the body.

6. The system of claim 5 , comprising a second flexible strand coupled to the bone plate and a second tissue anchor coupled to a first end of the second flexible strand.

7. The system of claim 1 , wherein the first anchor is selected from the group consisting of a knot capsule, a bone plate, a tissue anchor, and a button.

8. The system of claim 1 , wherein the second anchor is selected from the group consisting of a knot capsule, a bone plate, a tissue anchor, and a button.

9. A system, comprising:
a bone plate having a body extending between a bone facing surface and an opposing surface, the body defining a hole therethrough sized and configured to receive a portion of a flexible construct therethrough;
a flexible strand defining an adjustable loop extending between the bone facing surface of the bone plate and an anchor, the flexible strand having a first end extending from the opposing side of the bone plate; and
a tissue anchor coupled to the first end of the flexible strand, wherein the tissue anchor is configured to couple the flexible strand to a tissue section to maintain the adjustable loop at a predetermined length between the bone plate and the anchor.

10. The system of claim 9 , wherein the tissue anchor comprises a body defining a channel extending from a first end to a second end of the body, wherein the flexible strand extends from the first end of the body through the channel to the second end, around the second end of the body, and returns to the first end of the body along an outer surface of the body to define a loop.
