Jones' and dancer's fractures occur from rolling the ankle inward, with the peroneus brevis muscle on the outside of the leg pulling or avulsing the "base" of the 5th metatarsal off of the rest of the metatarsal. Prevention-wise, anything that prevented the greater magnitude inversions would decrease the liklihood of the injury. An ASO brace (the black band you see above many collegiate and professional players shoes) would do the trick as would standard physical therapy protocols for ankle instability (commonly used by athletic trainers). I wonder if peroneal strengthening exercises alone might actually cause an increased likelihood of injury - more likely to pull the base of the bone off?
