Do I Suffer From Over-Pronation Of The Feet

posted on 05 Jun 2015 22:58 by alejandra1sellers89
Overview

Pronation is a turning outward of the foot at the ankle, so that one has a tendency to walk on the inner border of the foot. (Pronation is the opposite of supination). When a foot and ankle pronates to a great degree, we call it over-pronation. During the normal gait cycle, we all pronate and then rapidly recover. It is over-pronation that patients are concerned with. This is a static deformity associated with flat feet and sometimes with foot and arch pain.Over Pronation

Causes

There are many possible causes for overpronation, but researchers have not yet determined one underlying cause. Hintermann states, Compensatory overpronation may occur for anatomical reasons, such as a tibia vara of 10 degrees or more, forefoot varus, leg length discrepancy, ligamentous laxity, or because of muscular weakness or tightness in the gastrocnemius and soleus muscles. Pronation can be influenced by sources outside of the body as well. Shoes have been shown to significantly influence pronation. Hintermann states that the same person can have different amounts of pronation just by using different running shoes. It is easily possible that the maximal ankle joint eversion movement is 31 degrees for one and 12 degrees for another running shoe.

Symptoms

If you overpronate, your symptoms may include discomfort in the arch and sole of foot, your foot may appear to turn outward at the ankle, your shoes wear down faster on the medial (inner) side of your shoes. Pain in ankle, shins, knees, or hips, especially when walking or running are classic symptoms of overpronation. Overpronation can lead to additional problems with your feet, ankles, and knees. Runners in particular find that overpronation can lead to shin splints, tarsal tunnel syndrome, plantar fasciitis, compartment syndrome, achilles tendonitis, bunions or hallux valgus, patello-femoral pain syndrome, heel spurs, metatarsalgia.

Diagnosis

You can test for pronation by looking at the leg and foot from the back. Normally you can see the Achilles Tendon run straight down the leg into the heel. If the foot is pronated, the tendon will run straight down the leg, but when it lies on the heel it will twist outward. This makes the inner ankle bone much more prominent than the outer ankle bone.Foot Pronation

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.

Surgical Treatment

The MBA implant is small titanium device that is inserted surgically into a small opening between the bones in the hind-mid foot: the talus (ankle bone) and the calcaneus (heel bone). The implant was developed to help restore the arch by acting as a mechanical block that prevents the foot from rolling-in (pronation). In the medical literature, the success rate for relief of pain is about 65-70%. Unfortunately, about 40% of people require surgical removal of the implant due to pain.
