Augmented suture construct for syndesmotic stabilization
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.
1 . An anchoring system, comprising:
an anchoring construct, including:
a first anchor;
a second anchor;
a first flexible strand defining an adjustable loop extending between the first anchor and the second anchor, the first flexible strand having a first end extending away from the first and second anchors;
a tissue anchor coupled the first end of the flexible strand and configured to couple the first end of the flexible strand to a first tissue section; and
a bone plate defining a hole therethrough, wherein the first anchor and the flexible strand of the anchoring construct are sized and configured for insertion through the hole.
2 . The system of claim 1 , wherein the first end of the at least one flexible strand 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 at least one flexible strand extends at least partially into the channel.
4 . The system of claim 3 , wherein the at least one flexible strand defines a loop about a portion of the body of the tissue anchor.
5 . The system of claim 1 , 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.
6 . 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.
7 . 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.
8 . A method, comprising:
forming a bone tunnel through a first bone and a second bone;
positioning a plate on the first and the second bones, the plate defining a plate hole that is essentially coaxial with the bone tunnel;
inserting a flexible construct through the plate hole into the bone tunnel, the flexible construct including 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 including a first end extending from the first anchoring element in an opposite direction from the adjustable loop;
adjusting a length of the adjustable loop to position the first bone and the second bone in a selected spacing; and
coupling the first end of the at least one flexible strand to a tissue section using a third anchoring element.
9 . The method of claim 8 , comprising adjusting a length of an intermediate portion of the at least one flexible strand.
10 . The method of claim 8 , wherein the third anchoring element comprises a tissue anchor.
11 . The method of claim 10 , wherein the first end of the at least one flexible strand is coupled to the tissue section by an interference fit.
12 . The method of claim 11 , wherein the tissue anchor comprises a body defining a channel, and wherein the at least one flexible strand extends at least partially into the channel.
13 . The method of claim 8 , wherein the at least one flexible strand defines a loop about a portion of the body of the tissue anchor.
14 . The method of claim 8 , wherein the first anchoring element is selected from the group consisting of a knot capsule, a bone plate, a tissue anchor, and a button.
15 . The method of claim 8 , wherein the second anchoring element is selected from the group consisting of a knot capsule, a bone plate, a tissue anchor, and a button.
16 . The method of claim 8 , coupling a second free end of the at least one flexible strand to the tissue section using a fourth anchoring element, wherein the second end extends from the first anchoring element in an opposite direction from the adjustable loop.
17 . The method of claim 8 , comprising coupling a bone plate to the first bone, wherein the flexible construct passes therethrough the bone tunnel through a hole defined by the bone plate.
