A cable used in spinal surgery has one crimp of a two crimp assembly crimped to one end of it. The second crimp has a ball held in a socket of the first crimp. The other end of the cable is passed around the bone or bones and any necessary orthopedic spinal device and it is then passed through an aperture in the second crimp. The cable is then tensioned by application thereto of a tensioning tool with the tool applied to the cable and to an abutment face of the second crimp, whereupon the cable is tensioned, with the ball and socket arrangement enabling swiveling of the crimps with respect to each other, thus minimizing sharp bends in the cable. Then the second crimp portion receiving the cable portion in the aperture adjacent the tensioning tool is crimped onto that cable portion to complete the attachment. Then the tensioning tool is removed, and the free end of the cable is cut off at the abutment surface. Other embodiments include a bar with two swivel crimps captured therein and a cable passing from one of the crimps around some spinal processus and back into the other of the crimps. A further embodiment includes a bar with sets of concave seats for engaging but not capturing swivel crimps. A further embodiment includes a base factory-crimped to one end of the cable, and concave seats on opposite sides of the base for swivel mounting but not capturing a ball crimped to another portion of the cable.
