What Causes Overpronation Of The Feet

Overview

Over-pronation is very common and affects millions of people. To better understand this condition, we'll take a closer look at the 3 most common foot types. An estimated 70% of the population has fallen arches (or a low arch). Only 20% has a normal arch. And 10% have abnormal feet, in other words they either have flat feet or the opposite a high arched foot.Overpronation

Causes

There are many biomechanical issues that can contribute to excessive pronation, including weak foot intrinsic muscles, limited ankle dorsiflexion mobility and calf flexibility, weak ankle invertor muscles (e.g. posterior tibialis), weak forefoot evertor muscles (peroneus longus), poor hip strength and control, Anterior pelvic tilting, heel InversionIn a person who overpronates, the heel bone goes into an everted position meaning that it turns out away from the midline of the body. The opposite motion of eversion is inversion. Inversion is a motion that needs to be controlled to prevent the foot from excessively pronating.

Symptoms

When standing, your heels lean inward. When standing, one or both of your knee caps turn inward. Conditions such as a flat feet or bunions may occur. You develop knee pain when you are active or involved in athletics. The knee pain slowly goes away when you rest. You abnormally wear out the soles and heels of your shoes very quickly.

Diagnosis

To easily get an idea of whether a person overpronates, look at the position and condition of certain structures in the feet and ankles when he/she stands still. When performing weight-bearing activities like walking or running, muscles and other soft tissue structures work to control gravity's effect and ground reaction forces to the joints. If the muscles of the leg, pelvis, and feet are working correctly, then the joints in these areas such as the knees, hips, and ankles will experience less stress. However, if the muscles and other soft tissues are not working efficiently, then structural changes and clues in the feet are visible and indicate habitual overpronation.Foot Pronation

Non Surgical Treatment

If a young child is diagnosed with overpronation braces and custom orthotics can be, conjunction with strengthening and stretching exercises, to realign the bones of the foot. These treatments may have to continue until the child has stopped growing, and orthotics may need to be worn for life in order to prevent the foot reverting to an overpronated state. Wearing shoes that properly support the foot, particularly the arch, is one of the most effective treatments for overpronation. Custom-made orthotic inserts can also be very beneficial. They too support the arch and distribute body weight correctly throughout the foot. Motion-control shoes that prohibit pronation can be worn, so may be useful for those with severe overpronation. One good treatment is to walk barefoot as often as possible. Not relying on shoes to support the arch will encourage proper muscle use. Practicing yoga can help to correct poor posture and teach you how to stand with your weight balanced evenly across the whole foot.

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.
