A method and apparatus for reattaching soft tissue to a boney structure using an expanding suture anchor. The method can include providing a suture anchor and forming a cavity in the boney structure for receipt of the suture anchor. The method can also include coupling the soft tissue to a suture and coupling the suture to the suture anchor. The method can further include deploying the suture anchor to fix the suture to the suture anchor and the suture anchor to the cavity.

An implant system for dynamic stabilization of a syndesmosis joint,. The system includes a soft bone anchor, a dynamic bone anchor and a tether coupled to and extending between the soft bone anchor and the dynamic bone anchor. The first and second retention portions of the tether are knotlessly coupled to the dynamic bone anchor, and an intermediate portion of the tether extends between the first and second retention portions and passes through the soft bone anchor. A medial portion of the intermediate portion extends into the dynamic bone anchor and is resiliently coupled to the dynamic bone anchor. The system further includes an insertion and tensioning instrument, the soft bone anchor being removably retained on a free end of a first portion of the instrument, and the dynamic bone anchor being removably retained on at least one of the first portion and a second portion of the instrument.
