One of the most common causes of foot and leg discomfort is a condition known as overpronation. Normal pronation, or "turning inward" of the foot is necessary as the foot adapts to the ground. With over pronation, the arch flattens, collapses, and soft tissues stretch. This causes the joint surfaces to function at unnatural angles to each other. When this happens, joints that should be stable now become very loose and flexible. At first, over pronation may cause fatigue. As the problem gets worse, strain on the muscles, tendons, and ligaments of the foot and lower leg can cause permanent problems and deformities.
Overpronation often occurs in people with flat feet, whose plantar fascia ligament is too flexible or too long, and therefore unable to properly support the longitudinal arch of the foot. People tend to inherit the foot structure that leads to overpronation. In a normal foot the bones are arranged so that two arches are formed, the longitudinal and the transverse. Ligaments hold all the bones in their correct positions, and tendons attach muscles to bones. If the bones are held together too loosely, they will tend to move inwards as this is the easiest direction for them to go. Over time the soft tissue structures will adjust to the misalignment and the foot will become permanently over-flexible, with a flat arch.
Common conditions seen with overpronation include heel pain or plantar fasciitis. Achilles tendonopathy. Hallus Valgus and/or bunions. Patellofemoral pain syndrome. Iliotibial band pain syndrome. Low back pain. Shin splints. Stress fractures in the foot or lower leg.
At some point you may find the pain to much or become frustrated. So what are you options? Chances are your overpronation has led to some type of injury if there's pain. Your best bet is to consult with someone who knows feet. Start with your pediatrist, chiropodist or chiropractor. They'll be able to diagnose and treat the injury and give you more specific direction to better support your feet. One common intervention is a custom foot orthotic. Giving greater structural support than a typical shoe these shoe inserts can dramatically reduce overpronation.
Non Surgical Treatment
If you overpronate, you should talk with a foot and ankle specialist, especially if symptoms have not developed yet. Questions you may want to ask your doctor include what are the best running shoes on the market? Where can I find those shoes? If over-the-counter orthotics don?t work, how long should I wait before contacting you for custom-made orthotics? On my next visit, what type of diagnostic testing should I expect? If I limit the amount of time I spend running, will my overpronation symptoms disappear? What additional treatment options can we try?
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.
