    Abstract:

    Objective To develop a three-dimensional finite element model of human foot for studying stress distribution of the hind foot bones during the jumping moment. Methods CT scanning and CAD/CAM software were used to establish the hind foot bones model. By using plantar pressure of back flop high-jump and calculating the inverse muscle strength, the loads and constraints conditions were simulated. Results Stress distribution of calcaneus、talus and navicular were analyzed during the landing of heel. Stress concentration was found at subtalar joint and dorsal of talus. Conclusion This model can be applied in biomechanical studies of the hind foot bones, especially for providing analytic data to explain the mechanism of jumping-induced injury.
