Objective: Through analyzing ligament damage around the ankle of elite race walkers, impact of damage on talus stability was analyzed. Methods: Through analysis of 3,200 injured race walkers from physical culture institutes and sports teams in a city, who were injured during June 2012-June 2015, the impact of ligament damage around the ankle on talus stability was analyzed, ankle injury was analyzed with spiral CT scan data, and three-dimensional aggregation model of foot and ankle was built with three-dimensional reconstruction software.
Results: The three-dimensional finite element models of normal human foot and ankle were built. Internal and external rotation of ankle cause different effects on biomechanics of talus.
Conclusion: Under external rotation forces, tibiotalar ligament of athletes will exert important impact on stability of ankle.
