Overview
Pes planus is the scientific term that describes low arch or "flat" feet. As podiatric physicians, we are very interested not only in structure but also in function of the feet. While very few people have 20-20 vision, it is also true that very few people have perfect arch structure. High and low arch feet are just the two ends of the spectrum of foot structure. The more deviation from what is considered perfect, the worse the function becomes. We describe deviation from "the ideal" as imbalance in structure. It is the imbalance in structure that leads to abnormal function. Abnormal function causes pain and/or deformity. Deformity can manifest itself in a variety of foot problems such as bunions or hammertoes. Likewise, pain can manifest itself in a variety of ways such as heel pain ( plantar fasciitis or heel spur), corns or calluses, metatarsalgia or pain in the ball of the foot ( neuromas, stress fractures, or tendonitis), or even in pediatric problems. Invariably, we can treat most foot imbalance or biomechanical insufficiencies with orthotic therapy.


Causes
In most cases, plantar fasciitis develops without a specific, identifiable reason. There are, however, many factors that can make you more prone to the condition. Tighter calf muscles that make it difficult to flex your foot and bring your toes up toward your shin. Obesity. Very high arch. Repetitive impact activity (running/sports). New or increased activity.Although many people with plantar fasciitis have heel spurs, spurs are not the cause of plantar fasciitis pain. One out of 10 people has heel spurs, but only 1 out of 20 people (5%) with heel spurs has foot pain. Because the spur is not the cause of plantar fasciitis, the pain can be treated without removing the spur.

Symptoms
Flat feet don't usually cause problems, but they can put a strain on your muscles and ligaments (ligaments link two bones together at a joint). This may cause pain in your legs when you walk. If you have flat feet, you may experience pain in any of the following areas, the inside of your ankle, the arch of your foot, the outer side of your foot, the calf, the knee, hip or back, Some people with flat feet find that their weight is distributed unevenly, particularly if their foot rolls inwards too much (overpronates). If your foot overpronates, your shoes are likely to wear out quickly. Overpronation can also damage your ankle joint and Achilles tendon (the large tendon at the back of your ankle). See your GP if you or your child has flat feet and your feet are painful, even when wearing supportive, well-fitting shoes, shoes wear out very quickly, feet appear to be getting flatter, feet are weak, numb or stiff, Your GP may refer you to a podiatrist (foot specialist).

Diagnosis
Your doctor may order imaging tests to help make sure your heel pain is caused by plantar fasciitis and not another problem. X-rays provide clear images of bones. They are useful in ruling out other causes of heel pain, such as fractures or arthritis. Heel spurs can be seen on an x-ray. Other imaging tests, such as magnetic resonance imaging (MRI) and ultrasound, are not routinely used to diagnose plantar fasciitis. They are rarely ordered. An MRI scan may be used if the heel pain is not relieved by initial treatment methods.

Non Surgical Treatment
An orthotic arch support, specially molded to fit your foot, may be part of your treatment. These supports can be particularly helpful if you have flat feet or high arches. You can tell if that is what is needed when short-term taping decreases your heel pain.


Surgical Treatment
In adults, the most common cause of collapse is due to the posterior tibial tendon tear. In such cases, the tendon must be repaired and a second tendon may be added to the posterior tibial tendon for strength and added support. If the foot is found to be very flat, bone realignment procedures or possible bone fusion procedures may be used to realign the foot. If the calf or Achilles tendon are found to be tight, they may be lengthened to allow better motion at the ankle and less arch strain. The forefoot may also be in a poor position and stabilization of the arch may be necessary to increase forefoot contact to the ground.


Prevention
So how do you prevent plantar fasciitis? Factors which can be controlled include training progression, environmental factors, shoes, and strength and flexibility exercises. A useful guideline for a safe training progression is ?the 10% rule.? Limit increases in distance or intensity to 10% a week. For example, if a person is running 60 minutes at a session, 4 times a week, or 240 minutes, she or he can probably increase the running time to 264 minutes (240 + 10%), the following week if all else remains the same. Terrain is also an important factor in training. Running 30 minutes on hills is very different from running 30 minutes on flat surfaces in terms of the forces on the legs and feet. Work up gradually to increase your running time on hills. Also lean forward when running downhill. If you run on a banked or crowned surface, vary the direction you run in so you alternate which leg is higher and which leg is lower on the bank. If you know concrete or asphalt is causing you discomfort, try running on a cinder or composite track. If you are going on vacation and are not used to running on sand or grass, don?t spend your whole vacation doing it.

Stretching Exercises
Calf Raises. Strengthens the tendons in your heels and calf muscles, which support your arch. Raise up on the balls of your feet as high as possible. Slowly lower down. Do three sets of 10 reps. Progress to doing the raises on stairs (with heels hanging off), and then to single-leg raises. Step Stretch. Improves flexibility in your Achilles tendon and calf-when these areas become tight, the arch gets painfully overloaded. Stand at the edge of a step, toes on step, heels hanging off. Lower your heels down, past the step, then raise back up to the start position. Do three sets of 10 reps. Doming. Works the arch muscles and the tibialis posterior (in the calf and foot) to control excess pronation. While standing, press your toes downward into the ground while keeping the heel planted, so that your foot forms an arch (or dome). Release, and do three sets of 10 reps on each foot. Toe Spread and Squeeze. Targets the interossei muscles of the foot, which support the arch. While sitting, loop a small resistance band around your toes. Spread toes; release. Then place a toe separator (used at nail salons) in between toes. Squeeze toes in; release. Do three sets of 10 reps of each exercise on both feet. Towel Curls. Works the toe-flexor muscles that run along your arch to increase overall foot strength. Lay a small hand towel on the floor, and place one foot on the towel. Using just your toes, scrunch the towel toward you, hold, then slowly push the towel away from you back to start position. Do three sets of 10 reps on each foot.
