Foot Pain In The Arch In The Morning

Is Overpronation Of The Foot

Overview

Overpronation is a term that gets thrown around a lot by psuedo-experts and there is so much written online about it, that it can get very confusing to determine what is legitimate and what is not. Pronation is a normal motion of the foot that occurs when the ankle rolls inwards and the arch collapses. This is normal. Its not something evil. Overpronation is assumed to be when there is too much of it. There certainly is debate as to just how much is too much, as some people have large amounts and have no problems, other have small amounts and do have problems. It all comes down to individual differences and how much force is needed to stop the foot moving. The greater the force, regardless of the amounts of pronation, the more likely it is to be a problem. Some still like to debate if it is a problem or not. Some studies have shown that its not a problem and other studies have shown it is. If the data from all these studies are pooled, then the conclusion was that, yes, overpronation is a problem that was statistically significant, but it was only a small risk factor for problems. An associated finding of overpronation during a gait analysis is an abductory twist.Over-Pronation

Causes

There may be several possible causes of over pronation. The condition may begin as early as birth. However, there are several more common explanations for the condition. First, wear and tear on the muscles throughout the foot, either from aging or repetitive strain, causes the muscles to weaken, thereby causing the foot to turn excessively inward. Also, standing or walking on high heels for an extended period of time also places strain and pressure on the foot which can weaken the tissue. Lastly, shoes play a very common factor in the development of over pronation. Shoes that fail to provide adequate support through the arch commonly lead to over pronation.

Symptoms

Overpronation can lead to injuries and pain in the foot, ankle, knee, or hip. Overpronation puts extra stress on all the bones in the feet. The repeated stress on the knees, shins, thighs, and pelvis puts additional stress on the muscles, tendons, and ligaments of the lower leg. This can put the knee, hip, and back out of alignment, and it can become very painful.

Diagnosis

Do the wet foot test. Get your feet wet and walk along a paved surface or sand and look at the footprints you leave. If you have neutral feet you will see a print of the heel with a thin strip connecting to your forefoot, but if you're overpronating your foot print will look a bit like a giant blob with toes.Pronation

Non Surgical Treatment

Overpronation is a term used to describe excessive flattening of the plantar arch. Pronation is a normal part of our gait (the way we walk), and it comprises three movements: dorsiflexion, eversion, and abduction. Dorsiflexion is the upward movement of the foot, eversion describes the foot rolling in, and abduction is ?out toeing,? meaning your toes are moving away from the midline of your body. When these three motions are extreme or excessive, overpronation results. Overpronation is very common in people who have flexible flat feet. Flatfoot, or pes planus, is a condition that causes collapse of the arch during weight bearing. This flattening puts stress on the plantar fascia and the bones of the foot, resulting in pain and further breakdown.

Surgical Treatment

Hyperpronation can only be properly corrected by internally stabilizing the ankle bone on the hindfoot bones. Several options are available. Extra-Osseous TaloTarsal Stabilization (EOTTS) There are two types of EOTTS procedures. Both are minimally invasive with no cutting or screwing into bone, and therefore have relatively short recovery times. Both are fully reversible should complications arise, such as intolerance to the correction or prolonged pain. However, the risks/benefits and potential candidates vary. Subtalar Arthroereisis. 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. HyProCure Implant. A stent is placed into a naturally occurring space between the ankle bone and the heel bone/midfoot bone. The stent realigns the surfaces of the bones, allowing normal joint function. Generally tolerated in both pediatric and adult patients, with or without adjunct soft tissue procedures. Reported removal rates, published in scientific journals vary from 1%-6%.
