| Abstract: | The ability of six different instruments to apply a cerclage wire under tension to a tension gage was compared. The loop knot produced greater final wire tension than the twist knot, both before and after bending. No significant difference in tension was found between the Swiss Osteo and A.S.I.F. instruments. The Rhinelander and Richards instruments gave approximately the same tension before the bend. The Rhinelander, Richards, and Vise Grip instruments showed no statistical difference in tension produced after the bend. The Bowen instrument developed the least amount of tension, both before and after bending the twist. All twist knots lost a significant amount of tension during the bending process. The twist-type knots that were twisted until breakage in the middle of the knot produced greater tension than those that were cut once they were tight. Cutting the twisted knot caused a significant decrease in wire tension. No correlation was found between operator pull and final cerclage wire tension. |
