Pronation is the term used to describe a natural movement of the foot when walking. When the gait is normal, the heel strikes the ground first. As weight is transferred forward, the arch of the foot
flattens and the foot rolls slightly inwards. Body weight is then placed on the ball of the foot and toes, and the foot straightens and turns outwards as the toes push off. Overpronation occurs when
the foot rolls inward too far. This causes all the muscles and tendons of the lower leg to twist excessively. Regular overpronation is believed to contribute to the development of many knee, lower
leg and foot injuries such as heel spurs, plantar fasciitis, tendinitis and bunions. It is thought that as much as 60% of the population may overpronate.
Over-pronation occurs when the foot collapses too far inward stressing the plantar fascia (the area underneath the arch of the foot.) Normally, one pronates every time he or she walks, but excessive
pronation is called over-pronation. When this occurs it can cause pain in the feet, knees, hips, low back and even the shoulder. Decreasing over-pronation, which is very prominent in runners, will
help add endurance, speed and efficiency to your run and ultimately place less stress on your body.
Symptoms can manifest in many different ways. The associated conditions depend on the individual lifestyle of each patient. Here is a list of some of the conditions associated with Over Pronation.
Hallux Abducto Valgus (bunions). Hallux Rigidus (stiff 1st toe). Arch Pain. Heel Pain (plantar fascitis). Metatarsalgia (ball of the foot pain). Ankle sprains. Shin Splints. Achilles Tendonitis.
Osteochondrosis. Knee Pain. Corns & Calluses. Flat Feet. Hammer Toes.
To easily get an idea of whether a person overpronates, look at the position and condition of certain structures in the feet and ankles when he/she stands still. When performing weight-bearing
activities like walking or running, muscles and other soft tissue structures work to control gravity's effect and ground reaction forces to the joints. If the muscles of the leg, pelvis, and feet are
working correctly, then the joints in these areas such as the knees, hips, and ankles will experience less stress. However, if the muscles and other soft tissues are not working efficiently, then
structural changes and clues in the feet are visible and indicate habitual overpronation.
Non Surgical Treatment
The way a foot orthotic works is by altering the weight-bearing surface of the foot. The simulated foot improvement is only possible when standing still with full weight applied. Orthotics are of
little help through most of the actual walking cycle. observationPatients may experience some symptom relief, but the orthotic cannot correct the internal osseous misalignment. Over-the-counter foot
orthotics are usually of little help and wear out quickly. Custom-made foot orthotics, obtained through your doctor's office, are generally expensive. Though they last longer and have less chance of
ill-effects than OTC brands, they still need to be replaced often. Over a lifetime, an individual can spend several thousands of dollars in total costs associated with orthotics and see little or no
results. This is because orthotics only work when you are wearing them and do not treat the cause of the problem. In many cases, the external pressure points created by orthotics can cause more
problems than solutions. Blisters, sore feet, sore joints and many other long-term complications can arise as a consequence of wearing orthotics.
Calcaneal "Slide" (Sliding Calcaneal Osteotomy) A wedge is cut into the heel bone (calcaneus) and a fixation device (screws, plate) is used to hold the bone in its new position. This is an aggressive
option with a prolonged period of non-weightbearing, long recovery times and many potential complications. However, it can and has provided for successful patient outcomes.
