When a foot over-pronates stress is unduly placed on the inside of the ankle and the knee, and over a long period of time, particularly if a person is involved in sports and running, this added stress starts to damage structures in the knee and ankle. The result is usually pain, particularly when running, which typically varies in severity. If the arch of the foot is weak, usually due to a lack of strength in supporting muscles of the foot, it can collapse over time, so people who aren?t flat footed can sometimes start to over-pronate in time. This can stress tissues on the underside of the foot, causing painful conditions like bunions (the abnormal inflammation and protrusion of the big toe?s joint) and Plantar Fasciitis (painful inflammation of connective tissues in the sole of the foot).Causes
During our development, the muscles, ligaments, and other soft tissue structures that hold our bones together at the joints become looser than normal. When the bones are not held tightly in place, the joints are not aligned properly, and the foot gradually turns outward at the ankle, causing the inner ankle bone to appear more prominent. The foot moves in this direction because it is the path of least resistance. It is more difficult for the foot to move in the opposite direction (this is called supination). As we develop, the muscles and ligaments accommodate to this abnormal alignment. By the time growth is complete, the pronated foot is: abnormally flexible, flat, and its outer border appears raised so that as you step down you do not come down equally across the entire foot; instead, you come down mostly on the inner border of the foot. Normal aging will produce further laxity of our muscles that causes the pronation to become gradually worse.Symptoms
Overpronation can negatively affect overall body alignment. The lowering of the longitudinal arch pulls the heel bone in, causing the leg, thigh bone and hip to rotate inwards, and an anterior tilt of the pelvis. Unnecessary strain to the ankles, knees, hips and back can result. Plantar fasciitis and inflammation, metatarsal pain, problems with the Achilles tendon, pain on the inside of the knee, and bursitis in the hip are just some of the conditions commonly associated with pronation.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.Non Surgical Treatment
If you overpronate, you should talk with a foot and ankle specialist, especially if symptoms have not developed yet. Questions you may want to ask your doctor include what are the best running shoes on the market? Where can I find those shoes? If over-the-counter orthotics don?t work, how long should I wait before contacting you for custom-made orthotics? On my next visit, what type of diagnostic testing should I expect? If I limit the amount of time I spend running, will my overpronation symptoms disappear? What additional treatment options can we try?Prevention
Custom-made orthotics supports not only the arch as a whole, but also each individual bone and joint that forms the arch. It is not enough to use an over-the-counter arch support, as these generic devices will not provide the proper support to each specific structure of the arch and foot. Each pronated foot?s arch collapses differently and to different degrees. The only way to provide the support that you may need is with a custom-made device. This action of the custom-made orthotic will help to prevent heel spurs, plantar fasciitis, calluses, arch pain, and weakness of the entire foot.

Sever?s Disease is often misdiagnosed as a simple growing pains and affects boys far more often than girls, especially between the ages of 8 and 14. It is extremely common in children that play Soccer, Basketball, And Hockey. However it is not limited to these sports alone, nor is it simply a pre-season type condition related to fitness. Sever?s Disease sounds terrible, but there is no need to panic as it is not a contagious or incurable condition. In children, there is a growth plate in the heel bone, which at puberty becomes solid and forms part of the heel, however prior to puberty it can cause pain if the child?s foot rolls inwards or outwards too much, causing increased stress on this growth plate and inturn causes pain.Causes
Overuse and stress on the heel bone through participation in sports is a major cause of calcaneal apophysitis. The heel?s growth plate is sensitive to repeated running and pounding on hard surfaces, resulting in muscle strain and inflamed tissue. For this reason, children and adolescents involved in soccer, track, or basketball are especially vulnerable. Other potential causes of calcaneal apophysitis include obesity, a tight Achilles tendon, and biomechanical problems such as flatfoot or a high-arched foot.Symptoms
Pain in the bottom surface and at the back of the heel. Extreme pain when the child places their heel on the ground. The pain is aggravated when running or jumping on hard surfaces. The pain is reduced when the child walks or runs on their toes.Diagnosis
Sever?s disease is diagnosed based on a doctor?s physical examination of the lower leg, ankle, and foot. If the diagnosis is in question, the doctor may order x-rays or an MRI to determine if there are other injuries that may be causing the heel pain.Non Surgical Treatment
See a Podiatrist. Minimise inflammation, by the use of ice, rest and reduction of activity. Minimise pain with the use of anti-inflammatory medications. Shoes have been shown to attenuate shock and reduce impact on the heel. Effective cushioning in the rear through specifcally placed cushioning units, such as GEL under the heel. A 10mm heel gradient that creates a more efficient foot posture and therefore reducing strain on the lower limb. Sever's is self limiting and only possible when the growth plate is still present, and does not exist once the growth plates have closed. Podiatrists have an important role to play in preventing and managing foot problems. Prompt action is important. Problems which are left without assessment or treatment may result in major health risks.Prevention
Having Sever?s disease does not predispose children or teens to any other condition, nor is it a permanent problem. It is self-limiting, and when treated, the pain and other symptoms will abate within a few weeks. Once the growth plate has finished growing, Sever?s disease will resolve and won?t recur. It is important to continue to treat any underlying foot conditions and to avoid any long periods of inactivity.

Becoming flatfooted can be a real health issue for people. The advice from healthcare experts is to pay attention to foot pain, and when it happens, to seek help right away. In the last 20 years, adult-acquired flatfoot has become a more commonly recognized health issue. The cause is a dysfunction of the ankle tendon that attaches to the bones on the inside of your foot. The function of this posterior tibial tendon (PTT) is to maintain the foot arch and provide strength during push-off when you walk. When the PTT is not functioning correctly, you tend to lose your arch, or become more flatfooted. This problem occurs about three times more often in women than in men, especially after the age of 40. Initially, PTT dysfunction is associated with pain on the inside of the ankle, swelling and sometimes a limp. If left unchecked, the arch appears to collapse and the pain on the inside of the ankle worsens. Eventually, if left unchecked, patients will begin to feel pain on the outside of the ankle, too.Causes
A person with flat feet has greater load placed on the posterior tibial tendon which is the main tendon unit supporting up the arch of the foot. Throughout life, aging leads to decreased strength of muscles, tendons and ligaments. The blood supply diminishes to tendons with aging as arteries narrow. Heavier, obese patients have more weight on the arch and have greater narrowing of arteries due to atherosclerosis. In some people, the posterior tibial tendon finally gives out or tears. This is not a sudden event in most cases. Rather, it is a slow, gradual stretching followed by inflammation and degeneration of the tendon. Once the posterior tibial tendon stretches, the ligaments of the arch stretch and tear. The bones of the arch then move out of position with body weight pressing down from above. The foot rotates inward at the ankle in a movement called pronation. The arch appears collapsed, and the heel bone is tilted to the inside. The deformity can progress until the foot literally dislocates outward from under the ankle joint.Symptoms
Symptoms of pain may have developed gradually as result of overuse or they may be traced to one minor injury. Typically, the pain localizes to the inside (medial) aspect of the ankle, under the medial malleolus. However, some patients will also experience pain over the outside (lateral) aspect of the hindfoot because of the displacement of the calcaneus impinging with the lateral malleolus. This usually occurs later in the course of the condition. Patients may walk with a limp or in advanced cases be disabled due to pain. They may also have noticed worsening of their flatfoot deformity.Diagnosis
In diagnosing flatfoot, the foot & Ankle surgeon examines the foot and observes how it looks when you stand and sit. Weight bearing x-rays are used to determine the severity of the disorder. Advanced imaging, such as magnetic resonance imaging (MRI) and computed tomography (CAT or CT) scans may be used to assess different ligaments, tendons and joint/cartilage damage. The foot & Ankle Institute has three extremity MRI?s on site at our Des Plaines, Highland Park, and Lincoln Park locations. These extremity MRI?s only take about 30 minutes for the study and only requires the patient put their foot into a painless machine avoiding the uncomfortable Claustrophobia that some MRI devices create.Non surgical Treatment
Flatfoot can be treated with a variety of methods, including modified shoes, orthotic devices, a brace or cast, anti-inflammatory medications or limited steroid injections, rest, ice, and physical therapy. In severe cases, surgery may be necessary.Surgical Treatment
If cast immobilization fails, surgery is the next alternative. Treatment goals include eliminating pain, halting deformity progression and improving mobility. Subtalar Arthroereisis, 15 minute outpatient procedure, may correct flexible flatfoot deformity (hyperpronation). The procedure involves placing an implant under the ankle joint (sinus tarsi) to prevent abnormal motion. Very little recovery time is required and it is completely reversible if necessary. Ask your Dallas foot doctor for more information about this exciting treatment possibility.
