  • Publication number: 20170231619
    Abstract: An apparatus includes first and second fixation members, a flexible member coupled to the first and second fixation members, and a limiting element coupled to the flexible member. The limiting element is movable relative to the second fixation member and acts to limit loosening of the flexible member relative to the second fixation member. The limiting element can be slidably received by the flexible member. The flexible member can be coupled to the fixation members such that pulling on a free end of the flexible member shortens a length of the flexible member between the fixation members.
