For those that are interested, Nicholas Giovinco, DPM, and I worked together last year on producing this animation of subtalar joint pronation and supination in a three-dimensional model. It is not perfect but is better than any other 3D animation that I have ever seen. http://drglass.org/vlog-podcast/2012…ssentials.html
