Metatarsal Stress Fracture
Runners push off from
their toes, putting great stress on the metatarsal heads. The 1st metatarsal
or stress fracture is isually immune to fracture because it is much thicker
and stronger than the others. The 5th metatarsal is relatively immune because
the major force of "toeing off" comes from the first 2. The 2nd, 3rd
and 4th metatarsals are usually susceptible because of their thin diaphyses.
