Over-pronation, or flat feet, is a common biomechanical problem that occurs in the walking process when a person's arch collapses upon weight bearing. This motion can cause extreme stress or
inflammation on the plantar fascia, potentially causing severe discomfort and leading to other foot problems.
In adults, the most common reason for the onset of Over-Pronation is a condition known as Post Tibial Tendonitis. This condition develops from repetitive stress on the main supporting tendon
(Posterior Tibial Tendon) of the foot arch. As the body ages, ligaments and muscles can weaken. When this occurs the job of providing the majority of the support required by the foot arch is placed
upon this tendon. Unfortunately, this tendon cannot bear the weight of this burden for too long. Eventually it fatigues under the added strain and in doing so the foot arch becomes progressively
lower over a period of time.
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.
If you have flat feet or low arches, chances are you overpronate. Although not always the case, the lower your arches the greater the overpronate. Stand on a hard surface (in front of a mirror if you
need to) and look at your feet, flat feet or low arches are easy to spot. If your feet look flatter than a pancake, have a look at your ankles and see if they seem collapsed or straight. If they are,
Non Surgical Treatment
One of the best forms of treatment for over pronation is wearing supportive shoes. Shoes should have ample support and cushioning, particularly through the heel and arch of the foot. Without proper
shoes, there may be additional strain on the tissue in the foot, greatly contributing to or causing an occurrence of over pronation. Rarely is surgery considered to relieve the pain and damage that
may have resulted from this condition. Orthotic shoe inserts are often the easiest and most effective way to correct pronation.
Subtalar Arthroereisis. Primary benefit is that yje surgery is minimally invasive and fully reversible. the primary risk is a high chance of device displacement, generally not tolerated in
An implant is pushed into the foot to block the excessive motion of the ankle bone. Generally only used in pediatric patients and in combination with other procedures, such as tendon lengthening.
Reported removal rates vary from 38% - 100%, depending on manufacturer.
