What Are The Main Reasons Behind Overpronation

posted on 30 May 2015 11:39 by timothy7bartlett1
Overview

Pronation occurs at the joint below the ankle, the subtalar joint. It describes the inward rolling motion of the foot just after it lands on the ground. This moment is called initial contact, which is part of the stance phase of the gait cycle. Urthotic Insoles are designed today specifically for different pronation patterns. When you pick your next pair of insoles, your pronation type is a very important factor in your choice.Overpronation

Causes

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.

Symptoms

Because overpronation affects the entire lower leg, many injuries and conditions may develop and eventually cause problems not only in the leg and foot, but also the knee, hips and lower back. Pain often begins in the arch of the foot or the ankle. Blisters may develop on the instep, or on the inside edge of the heels. As overpronation continues and problems develop, pain will be felt elsewhere, depending on the injury.

Diagnosis

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, you're overpronating.Over Pronation

Non Surgical Treatment

Although there is no actual cure for over-pronation it is possible to correct or at least reduce this problem. In order to restore our normal foot function an 'orthotic' or orthotic insole device is placed inside the shoes. Orthotics are designed to realign the foot and ankle bones to their natural position. This in turn restores our normal foot function and it helps alleviate not only foot problems but also ailments in other parts of the body i.e. the legs, knees and lower back. In addition to wearing an orthotic, it is recommended to wear supportive shoes, like good quality athletic footwear with a firm heel counter and sufficient flexibility in the forefoot area.

Surgical Treatment

Calcaneal "Slide" (Sliding Calcaneal Osteotomy) A wedge is cut into the heel bone (calcaneus) and a fixation device (screws, plate) is used to hold the bone in its new position. This is an aggressive option with a prolonged period of non-weightbearing, long recovery times and many potential complications. However, it can and has provided for successful patient outcomes.
