Static and Dynamic Cerclage Wire Analysis

Abstract

A new type of double loop cerclage wire, conventional single wire loop cerclage, and twist‐type cerclage were evaluated. The double loop cerclage was applied using the Osteo Systems double loop tightener. Two groups of single wire loop cerclage were applied using the Osteo System loop tightener and the Richards loop tightener. Two groups of twist‐type cerclage were applied using the Kirschner wire twister and side‐cutting pliers. The test system allowed determination of the static tension produced by each wire, as weH as its ability to resist distraction. The double loop cerclage wires were the most effective in producing static tension and in resisting distraction. While the conventional single loop cerclage wires produced more static tension than the twist cerclage wires, they were less effective in resisting distraction.
