Abstract:
[Objective]To evaluated the distraction-resisting force contributed by gastrocnemius during tibial lengthening.The force contributed by gastrocnemius during both the distraction and consolidation phases in a rabbit model of tibial lengthening were measured by an in-line strain gauged bilateral fixator.[Method]Sixteen immature New Zealand White rabbits underwent 30% (left) tibial diaphyseal lengthening at a rate of two 0.4 mm increments per day.[Result]The contribution of the gastrocnemius distraction-resisting force at the end of lengthening (11?5N,25%?7%) was statistically higher than that of 5 weeks later (3?1 N,13%?5%)(P
