Abstract
A bone cable strap and surgical instruments pass the cable strap around a bone, tension it, fasten it and trim the excess cable. The surgical instruments include: a cable passer which has an arcuate guiding member having a groove facing the bone to guide the cable around the bone; a cable tensioner having concentric tubular members with a cable clamp at one end, a nipple at the other end, and a handle in between such that turning the handle spreads the cable clamp away from the nipple; and a combination cable crimper-cutter having jaws with both crimping and cutting edges. The cable strap is comprised of a flexible cable having a ferrule pre-affixed to one end. The cable is passed under the bone using the cable passer. The free end of the cable is passed through the ferrule and the cable tensioner is used to draw the cable tight around the bone. The crimper-cutter is then used to fasten the ferrule in place about the cable and trim the excess cable.
