Over-pronation describes a characteristic gait wherein a lack of sufficient support from the arch of the foot causes it to roll inwards as weight is placed on it. The long arch of the foot is
actually a very important structure in terms of our gait and how we walk, it is responsible for ensuring that as our weight rolls from the heel to the balls of our feet it does so in a straight line
that doesn?t place undue stress on the ankle or knees. Unfortunately when a person?s arch is not pronounced enough, or even simply not there (a condition called flat footedness), there isn?t enough
arch support to maintain a healthy, forward motion of the foot.
Congenital "Flat Feet" - an individual may be born with feet that lack an appropriately supportive arch thereby predisposing the individual to this foot condition. Excessive Weight (Obesity) Too much
weight on the foot from either obesity or pregnancy may be a factor. Repetitive Impact walking on flat, hard surfaces continuously places unnatural stress on the foot arch.
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.Unfortunately, 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 (hallux valgus) patello femoral pain
syndrome, heel spurs, metatarsalgia. You do not have to be a runner or athlete to suffer from overpronation. Flat feet can be inherited, and many people suffer from pain on a day-to-day basis. Flat
feet can also be traumatic in nature and result from tendon damage over time. Wearing shoes that do not offer enough arch support can also contribute to overpronation.
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.
Non Surgical Treatment
No matter what the cause in your case, over pronation can be remedied in several ways. Those who are overweight should consider permanently losing weight to naturally alleviate pressure on the
ligaments and heel of the foot. Also, you should consult a podiatrist to examine your posture and movement habits. You may be reinjuring yourself due to poor alignment without even knowing it. If you
also have lower back problems, this could be a sign of over pronation as a result of misalignment.
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.
