Tarsal functions, movement, and stabilization mechanisms in foot, ankle, and leg performance

The authors investigated the function of the tarsus and the skeletal segmen ts of the foot in terms of the biomechanical significance of the individual links of the foot-ankle-leg complex. A performance model based on pressure -washed trabecular systems and the interface of the different segments maki ng up the articular foot skeleton is presented and discussed. The biomechan ical influence of these segments on each other and on their appendicular co mpanion bones is assessed, and an explanation of their function is provided .
