Overpronation Of The Feet
Overview
Over-pronation, or flat feet, is a common biomechanical problem that occurs in the walking process when a person's arch collapses upon weight bearing. This motion can cause extreme stress or inflammation on the plantar fascia, potentially causing severe discomfort and leading to other foot problems.
Causes
You do not have to be a runner or athlete to suffer from overpronation. Flat feet can be inherited, and many people suffer from pain on a day-to-day basis. Flat feet can also be traumatic in nature and result from tendon damage over time. Wearing shoes that do not offer enough arch support can also contribute to overpronation.
Symptoms
Symptoms can manifest in many different ways. The associated conditions depend on the individual lifestyle of each patient. Here is a list of some of the conditions associated with Over Pronation. Hallux Abducto Valgus (bunions). Hallux Rigidus (stiff 1st toe). Arch Pain. Heel Pain (plantar fascitis). Metatarsalgia (ball of the foot pain). Ankle sprains. Shin Splints. Achilles Tendonitis. Osteochondrosis. Knee Pain. Corns & Calluses. Flat Feet. Hammer Toes.
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.
Non Surgical Treatment
The following exercises help retrain the foot and ankle complex to correct overpronation. Step Up and Over. This exercise is designed to integrate skills learned in the Duck Stand, Big Toe Pushdowns and Side Step with Opposite Reach exercises to mimic walking and even running. Using the gluteal muscles and big toe in tandem will prevent overpronation while moving back and forth over the BT in a more effective, balanced motion. Movement Directions. Stand with left foot on top of the BT dome. (Note: For added balance, the right foot can tap on the ground, if needed). Extend right foot backwards to the ground and drop hips into a lunge position. Make sure that the right arm rotates across the left leg (this will activate the gluteal muscles on the left side). Now, step through and over the BT into a front lunge with the right leg forward. While lunging forward, the torso and left arm now rotate over the right leg. Throughout the exercise, push big toe down into the BT. Perform 8 to 10 repetitions on both sides.
Surgical Treatment
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 from 1%-6%.

How To Get Rid Of Bunions
Overview
Bunions are one of the more serious conditions that can affect foot health. A bunion is actually a bone deformity of the big toe, where the joint at the base and side of the toe is enlarged, forcing the toe out of place. Left untreated, bunions worsen over time. The big toe angles in toward the rest of the toe, and can overlap the third toe (a condition known as Hallux Valgus). Or, it may move toward the second toe and twist or rotate (Hallus Abducto Valgus). Bunions can also lead to deformities like hammertoes. Bunions cause discomfort and pain, because the enlargement constantly rubs against footwear. The skin of the toe becomes red and tender. The larger a bunion grows, the more painful it is to walk. People with bunions can develop thickening skin on the bottom of the foot, bursitis or arthritis, and chronic pain.
Causes
The most common cause of bunions is wearing shoes that are too tight. The condition is not hereditary, but it does tend to run in families-often due to a faulty foot structure. Other causes of this condition might be neuromuscular problems, flat feet, pronated feet, or foot injuries.
Symptoms
The dominant symptom of a bunion is a big bulging bump on the inside of the base of the big toe. Other symptoms include swelling, soreness and redness around the big toe joint, a tough callus at the bottom of the big toe and persistent or intermittent pain.
Diagnosis
A simple visual exam is all it will take for your doctor to determine whether you have a bunion. He or she may also ask you to move your big toe in order to ascertain your range of motion. Your doctor may also look for any inflammation, redness, or pain. X-rays can help your doctor determine the severity and cause of the bunion. Your doctor may also ask you questions about your footwear, the symptoms you are experiencing, and if other family members also suffer from the condition. All these factors will help him or her diagnose you properly.
Non Surgical Treatment
Many people with bunions are quite comfortable if they wear wide, well fitting shoes and give them time to adapt to the shape of their feet. A small pad over the bony prominence, which can be bought from a chemist or chiropodist, can take the pressure of the shoe off the bunion. High heels tend to squeeze the foot into the front of the shoe and should be avoided. It is often worthwhile seeing a chiropodist if these simple measures are not quite enough. 
Surgical Treatment
Depending on the severity of the deformity, this osteotomy can be done either at the end of the metatarsal (a distal osteotomy) or if the deformity is more severe, the osteotomy is performed at the base of the first metatarsal (a proximal osteotomy). One of the more common distal metatarsal osteotomies that is performed is called the chevron osteotomy. Typically a small screw is inserted into the bone to hold the metatarsal head in place and speed up bone healing. Following a chevron osteotomy, walking is permitted in a surgical shoe the next day after surgery and the shoe is worn for approximately three to four weeks before a more comfortable walking/running type shoe is worn.
Prevention
The best way to reduce your chances of developing a bunion is to wear shoes that fit properly. Any shoe that is too tight or too high will force your toes together and may cause the condition to develop. Shoes need to be wide enough, so they aren't rubbing against the joint, and preferably made of leather. Avoid shoes with a lot elaborate stitching at the front, as this can also cause irritation. Heels should be no more than three to four inches and you should only wear them occasionally. Court shoes should seldomly be worn, as they do not give the foot any support. Be honest with yourself, you know if your shoes aren't fitting you comfortably. Do something about it, or you will suffer for your vanity.
