Pronation is the natural act of the body spreading the impact of walking, jogging or running throughout the foot evenly. As the foot strikes the ground, the ankle naturally rolls inward absorbing the
shock of the ground and mobilizing to the terrain. Overpronation is when the ankle of the foot rolls in past its normal 15? of inward rotation. The cause of this could be many things such as foot
type, biomechanics, or compensation strategies. People with flat feet often, although not always, overpronate.
Over-pronation is very prominent in people who have flexible, flat feet. The framework of the foot begins to collapse, causing the foot to flatten and adding stress to other parts of the foot. As a
result, over-pronation, often leads to Plantar Fasciitis, Heel Spurs, Metatarsalgia, Post-tib Tendonitis and/or Bunions. There are many causes of flat feet. Obesity, pregnancy or repetitive pounding
on a hard surface can weaken the arch leading to over-pronation. Often people with flat feet do not experience discomfort immediately, and some never suffer from any discomfort at all. However, when
symptoms develop and become painful, walking becomes awkward and causes increased strain on the feet and calves.
Because overpronation affects the entire lower leg, many injuries and conditions may develop and eventually cause problems not only in the leg and foot, but also the knee, hips and lower back. Pain
often begins in the arch of the foot or the ankle. Blisters may develop on the instep, or on the inside edge of the heels. As overpronation continues and problems develop, pain will be felt
elsewhere, depending on the injury.
So, how can you tell if you have overpronation, or abnormal motion in your feet, and what plantar fasciitis treatment will work to correct it? Look at your feet. While standing, do you clearly see
the arch on the inside of your foot? If not, and if the innermost part of your sole touches the floor, then your feet are overpronated. Look at your (running/walking) shoes. If your shoes are more
worn on the inside of the sole in particular, then pronation may be a problem for you. Use the wet foot test. Wet your feet and walk along a section of pavement, then look at the footprints you leave
behind. A normal foot will leave a print of the heel connected to the forefoot by a strip approximately half the width of the foot on the outside of the sole. If you?re feet are pronated there may be
little distinction between the rear and forefoot.
Non Surgical Treatment
Overpronation is a condition in which the foot rolls excessively down and inward. The arch may elongate and collapse (or ?fall?) and the heel will lean inward. Overpronation should not be confused
with pronation. Pronation is a normal motion of the foot during weight bearing and allows the foot to absorb shock as it contacts the ground.
Subtalar Arthroereisis. The ankle and hindfoot bones/midfoot bones around the joint are fused, locking the bones in place and preventing all joint motion. This may also be done in combination with
fusion at other joints. This is a very aggressive option usually reserved for extreme cases where no joint flexibility is present and/or the patient has severe arthritic changes in the joint.
