Podiatry is a branch of medicine that deals with the study, diagnosis, and treatment of foot and ankle conditions. There are various subdivisions in podiatry; biomechanics is one of them. Biomechanics is the way in which the bones, muscles, and joints of the feet and lower limb interact with each other.

Our feet play crucial roles in the way we move, and it is rare to have feet that are completely symmetrical. Common biomechanical issues include high or low arches or uneven leg heights. Excessive pronation often leads to fallen arches, or flat feet, and is a common cause of running injuries. People whose feet are over-pronated tend to have flexible and unstable feet. Pain is usually experienced during walking and running.

At times, people may be able to adapt to these abnormalities without any difficulties, but in other cases, these issues can cause a great deal of pain. This pain occurs because the joints, muscles, ligaments, and tendons are put under an excess amount of stress during movement. Common symptoms of biomechanical problems stemming from the feet include hip pain, knee pain, leg cramps, ankle pain, lower back pain, weak ankles, tripping, heel pain, Achilles pain, and shin splints.

Many biomechanical issues can be treated with orthotics. Orthotics are shoe insoles that are used to help control the way the foot operates.  They can provide relief from foot pain, heel pain, and knee pain. Depending on your specific case, you may need to purchase over-the-counter orthotics or custom orthotics to fit your feet. Your podiatrist will be able to prescribe the perfect orthotic for your feet to help you walk around with ease.

Gait is defined as the way we move our bodies from one point to another. This is usually done by either walking or running. Gait analysis is a method used to assess the way we walk or run to highlight biomechanical abnormalities. Gait analyses are a great way to take a detailed look at how you walk and how your foot moves while you walk. An examination of the feet will help your podiatrist understand why you are suffering pain in other parts of your body.

A podiatrist will be able to address a variety of rare foot conditions, particularly the ones that affect children. The most common are Kohler’s disease, Maffucci syndrome, and Freiberg’s disease. They can be properly diagnosed by having an X-ray taken, but in more serious cases an MRI may be needed. Kohler’s disease generally affects younger boys and bone deterioration may result from an interruption of blood supply. Children who have Kohler’s disease may find relief when the affected foot is rested, and a special boot is worn. Benign growths in the long bones of a child’s foot may lead to the development of bone lesions, and this is known as Maffucci syndrome. People who have this condition find mild relief when custom-made orthotics are worn. Freiberg’s disease targets the ball of the foot and can typically affect pre-teen and teenage girls. The metatarsal bone becomes deteriorated and flattened, and common symptoms include swelling and stiffness. A cast is often necessary to wear with this disease as it can help to reduce existing pain. Erythromelalgia is a rare foot condition, and its cause is unknown. Symptoms of this disease can include intense burning pain and the feet may appear red or feel warm. Relief may be found when the affected foot is immersed in ice water. It can also be beneficial to elevate the foot frequently. If your child complains of foot pain, it is strongly suggested that you consult with a podiatrist who can diagnose and treat rare foot conditions. 

Sever's disease, also known as calcaneal apophysitis, is a medical condition that causes heel pain in children’s feet while they’re growing. Sever's disease occurs most commonly in boys and girls between the ages of 8 and 14.

Sever's disease occurs when the child’s growth plate, or the calcaneal epiphysis, an area attached to the Achilles tendon, is injured or when the muscles and tendons of the growing foot do not keep pace with bone growth. The result is constant pain experienced at the back of the heel and the inability to put any weight on the heel. This forces the child to bear weight on their toes while walking. When a toe gait develops, the child must change the way they walk to avoid placing weight on the painful heel. If this is not properly addressed, this can lead to further developmental problems.

The most common symptom of Sever's disease is acute pain felt in the heel when a child engages in physical activity such as walking, jumping or running. Children who are active athletes are among the group most susceptible to experiencing Sever's disease. This is due to the extreme stress and tension placed on their growing feet. The rolling movement of the foot during walking or running and obesity are both additional conditions linked to causing Sever's disease.

The first step in treating Sever's disease is to rest the foot and leg and avoid physical activity. Over the counter pain-relieving and anti-inflammatory medications can be helpful for reducing the amount of heel pain. A child with Sever's disease should also wear shoes that properly support the heel and the arch of the foot. Consider purchasing orthotic shoe inserts which can help support the heel and foot while it is healing. Most patients with Sever's disease symptoms report an eventual elimination of heel pain after wearing orthotic insoles that support the affected heel.

Sever's disease may affect either one heel or both. It is important for a child experiencing heel pain to be examined by a foot doctor who can apply the squeeze test. The squeeze test compresses both sides of the heel in order to determine if there is intense pain. Discourage any child diagnosed with Sever's disease from going barefoot as this can intensify the problem. Apply ice packs to the affected painful heel two or three times a day for pain relief.

Exercises that help stretch the calf muscles and hamstrings are effective at treating Sever's disease. An exercise known as foot curling has also proven to be very effective at treating Sever's disease. When foot curling, the foot is pointed away from the body, then curled toward the body to help stretch the muscles. The curling exercise should be done in sets of 10 or 20 repetitions and repeated several times throughout the day.

Treatment methods can continue for at least 2 weeks and as long as 2 months before the heel pain completely disappears. A child can continue doing daily stretching exercises for the legs and feet to prevent Sever’s disease from returning.

When conservative, noninvasive methods prove ineffective, surgery may be selected as the next course of action for the treatment of your foot or ankle condition.  A wide number of foot and ankle surgical procedures exist, and it is up to your podiatrist to determine which intervention will be most appropriate and helpful for your case.  Some surgical procedures include bunion surgery, fusion, hammertoe surgery, heel spur surgery, metatarsal surgery, nail surgery, neuroma surgery, reconstructive surgery, skin surgery, and tendon surgery.  Typically, surgery is turned to as a definitive way to alleviate excessive pain or discomfort and to return your foot to full mobility.

Regardless of the location on the body, all surgical procedures require preoperative testing and examination to ensure the surgery’s success and preferred outcome.  A review of your medical history and medical conditions will take place, as will an evaluation of any current diseases, illnesses, allergies, and medications.  Tests such as blood studies, urinalyses, EKG, X-rays, and blood flow studies may be ordered.  Because the procedure involves the foot and/or ankle, the structures of your feet while walking may also be observed by your podiatrist.

Care post-surgery will depend on the type of surgical procedure performed.  Typically, all postoperative care involves rest, ice, compression, and elevation.  To improve and ensure a safe recovery, your foot and ankle surgeon may also employ the use of bandages, splints, surgical shoes, casts, crutches, or canes.  He will also determine if and when you can bear weight.  A timely and thorough recovery is a priority for both you and your podiatrist, and carefully following postoperative instructions can help achieve this.  

If you want to ensure the long-term health of your feet, you should choose the right pair of shoes to wear on an everyday basis. Poorly fitting shoes will not only be uncomfortable, but they may also cause foot pain and unwanted foot conditions. When looking for a new pair of shoes, there are certain factors you should look for.

One of the most crucial tips you can follow is to always try shoes on in the afternoon. It is normal for feet to swell throughout the day, which means your shoe size may be different in the morning compared to what it is at night. To be safe, you should go with the slightly bigger size to ensure that your feet have enough room within your shoes.

Another rule is to never buy shoes that are too tight (Many people buy shoes that are too tight for their feet and expect the shoes to stretch out). If you are looking for a pair of running sneakers, you can go to a specialty running shoe store to have your feet properly sized. When you purchase shoes in-store, walk around in them to make sure the shoes you are going to buy fit you properly. Take some time to make sure the shoes are comfortable for your feet

The upper section of your shoe should be made from a softer, more flexible material. The material that makes up the shoe should not be slippery. Arch support should be a key factor in the decision-making process for shoes. Arch support is crucial because it will prevent the arches in your feet from collapsing. If your arches collapse, the plantar fascia may begin to stretch out which could lead to plantar fasciitis.

Many problematic foot conditions may be prevented by wearing properly fitting shoes. Some of these unwanted conditions are bunions, corns, calluses, pain, stress fractures, and plantar fasciitis. If you are suffering from any of these ailments you may want to speak with your podiatrist.
