<p>A tensioning tool (10) is used with a clip (52) through which the ends (56, 58) of a tension band (50) are placed after the tension band is positioned over the parts to be fastened such as adjacent spinous processes. The ends of the tension band are secured to pins (78, 80) on the tool and a tension shaft (40) is driven downwardly away from the pins, increasing the distance from the pins to the clip, thereby tightening the band. Once tightened as desired, a tension wrench (18) is inserted through the tool with a clip screw (54) positioned on its tip. It is then rotated until the screw is firmly seated in the clip, thereby trapping the band between the clip and the screw. The tool is then removed after releasing the band ends from the pins.</p> |
