Abstract
Abstract A surgical, orthopaedic cable attachment apparatus and method for the surgical repair or fusion of orthopaedic anatomical structures is constructed from a length of flexible cable formed of a braided polymeric material having a first and second end portion. A first loop is formed in the first end portion of the cable with a second loop is formed, being placed around or through the bone parts to be tied. After the second loop is place around the selected bone parts, the free cable end is passed through the first loop and pulled tight to define a tightened position. The free cable end can have a needle. The free end is then secured to the cable by splicing for example, to hold the cable in the tightened position.
