Samenvatting
The purpose of this paper is to model empirically the injury tolerance of the human ankle/subtalar joint to dynamic inversion under different loading conditions. The results of this study demonstrate that 2 kN of axial preload significantly increases both the moment and angle tolerance of the ankle/subtalar joint to forced inversion and eversion. Axial preloading also increases the likelihood of bone fracture in inversion and eversion. The evidence presented in this paper may be used to estimate the risk of injury that forced inversion and eversion would pose to human based on the rotation angle and axial leg load measured be a biofidelic anthropomorphic test device.
