Excessive pronation is a common fault that occurs with the dynamic structure of the foot. Some degree of pronation is necessary for shock absorption. Excessive pronation, or collapsing of the arch,
limits the foot?s ability to efficiently support the weight of the body. The altered position of the foot and ankle complex that occurs with high degrees of pronation also forces the rest of the
lower body out of alignment. This can cause mechanical problems in muscles and joints traveling all the way up to the back. Arch strengthening is a vital part of maintaining healthy feet.
Over-pronation is very prominent in people who have flexible, flat feet. The framework of the foot begins to collapse, causing the foot to flatten and adding additional stress to other parts of the
foot. Therefore over-pronation can often lead to a case of Plantar Fasciitis, Heel Spurs, Metatarsalgia, Post-tib Tendonitis and/or Bunions. There are many causes of flat feet. Obesity, pregnancy or
repetitive pounding on a hard surface can weaken the arch leading to over-pronation. People with flat feet often do not experience discomfort immediately, and some never suffer from any discomfort at
all. However, when symptoms develop and become painful, walking becomes awkward and causes increased strain on the feet and calves.
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.
When you overpronate your foot rolls inwards causing the lower leg to rotate inwards too. It's thought that this increases stress on the soft tissues of the lower leg causing pain and inflammation,
or more commonly known as shin splints.
Non Surgical Treatment
Over-pronation and the problems that go with it are treated with shoe inserts called arch supports or orthotics. You can buy orthotics at a pharmacy or athletic shoe store or they can be custom made.
Make sure the arch supports are firm. If you can easily bend them in half, they may be too flexible.
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
