Abstract
Methods and devices for repairing the TFCC of a patient's wrist are provided. In general, the device includes first and second anchor bodies that are connected to one another by a suture. The first anchor body is configured to be passed through a portion of the TFCC of a patient's wrist and an anchoring tissue, preferably using a delivery device, such that the first anchor body is positioned across a torn portion of the TFCC, the second anchor body is positioned across the anchoring tissue, and the suture extends therebetween. The suture can then be tensioned to anchor the TFCC to the anchoring tissue.
Claims23
An anchor system for repairing tears in the triangular fibrocartilage complex, comprising:
- a first anchor body having a central portion adapted to receive a suture, and opposed wing members extending from opposed sides of the central portion, the wing members defining a length that is greater than a height of the central portion;
- a second anchor body having a circular base with a substantially cylindrical central portion extending therefrom, the second anchor body include a bore extending through the circular base and the substantially cylindrical central portion for receiving a suture;
- and
- a suture loop extending through the central portion of the first and second anchor bodies, and including a slip knot formed therein and positioned adjacent the second anchor body.
A method for repairing tears in the triangular fibrocartilage complex of a patient's wrist, comprising:
- passing a delivery device through a portion of a torn triangular fibrocartilage complex of a patient's wrist at a first location, the delivery device carrying first and second anchor bodies that are connected to one another by a suture;
- releasing the first anchor body from the delivery device such that the first anchor body is resting against an anchoring tissue;
- passing the delivery device through a portion of the torn triangular fibrocartilage complex of a patient's wrist at a second location adjacent to the first location;
- releasing the second anchor body from the delivery device such that the second anchor body is resting against the anchoring tissue adjacent to the first anchor body, and the suture extends from the first anchor body and second anchors bodies across the torn triangular fibrocartilage complex, and a portion of the suture rests against a tissue surface opposed to the anchoring tissue;
- and
- tensioning the suture to re-approximate the torn triangular fibrocartilage complex.
