Pronation of the foot with many overuse injuries in running including medial tibial stress syndrome, or shin splints, and knee pain Hintermann states, “Individuals with injuries typically have pronation movement that is about two to four degrees greater than that of those with no injuries.” He adds however, that between 40% and 50% of runners who overpronate do not have overuse injuries. This suggests that although pronation may have an effect on certain injuries, it is not the only factor influencing their development. The design principles of foot orthoses are founded on knowledge of the functional anatomy of the foot. Pronation of the foot
Posterior tibial artery Posterior tibial artery The posterior tibial artery of the lower limb carries blood to the posterior compartment of the leg and plantar surface of the foot, from the popliteal artery via the tibial-fibular trunk. It is accompanied by a deep vein, the posterior tibial vein, along its course. The PT gives rise to the medial plantar artery, lateral plantar artery, and gives rise to the fibular artery. Often, the branch of the fibular artery is said to rise from the bifurcation of the tibial-fibular trunk and the posterior tibial artery. In addition a calcaneal branch to the medial aspect of
