Overview
Flat feet is the most common foot deformity known. In fact, sixty million Americans or 25% of the U.S. population have flat feet. Some of these people may experience problems that limit their activities, while others can run marathons or play in the NBA.


Causes
Often, tarsal tunnel syndrome is misdiagnosed and confused with plantar fasciitis. Tarsal tunnel syndrome is when the tibial nerve which runs through the ankle, is pinched as it passes through the flexor retinaculum, the supportive band that surrounds the ankle joint. The symptoms of tarsal tunnel syndrome are often limited to the ankle but the since the nerve passes through the entire foot it can cause arch pain. Arch pain associated with foot strain is mainly caused by a pronated foot (rolls inward) or a flat foot. These are usually not singular causes of arch pain, but in combination with other factors, arch pain may result.

Symptoms
Arch pain symptoms could include any of the following, a dull, constant ache if the ligaments have been stretched, swelling or tenderness in the foot, redness or bruising in the event of a more serious injury, difficulty putting weight on the foot, sharp pain when the foot is turned or manipulated, tenderness when pressure is applied. Because the arch of the foot is such a complex structure, arch pain could be an indicator of several different types of injuries. Chronic illnesses such as arthritis could also cause arch pain, and depending on the cause or source of your pain, you may experience discomfort in a variety of different areas. Ask a doctor if you believe you may have injured your foot arch.

Diagnosis
In people with flat feet, the instep of the foot comes in contact with the ground when standing. To diagnose the problem, the health care provider will ask you to stand on your toes. If an arch forms,the flat foot is called flexible. You will not need any more tests or treatment. If the arch does not form with toe-standing (called rigid flat feet), or if there is pain, other tests may be needed, including a CT scan to look at the bones in the foot. MRI scan to look at the tendons in the foot. X-ray of the foot.

Non Surgical Treatment
Once the severity and cause of arch and foot pain is determined, a course of corrective and rehabilitative actions can be started. Therapists may use machines and manual therapies to reduce pain and increase circulation to the area to promote healing. Maintenance of fitness levels via modification of activity may be prescribed. Substitute activities that may aggravate the pain and soreness with other activities; for instance, running causes the body to have multiple impacts with the ground, but the use of bicycling, elliptical trainers, step machines, swimming, or ski machines eliminates impact and allows you to continue to maintain and improve your fitness levels. Take medications to help reduce pain and inflammation. Follow up with your doctor until you are better.


Surgical Treatment
With flat feet, there is a tendon on the inside of the foot than can often become weakened, injured, split and/or ruptured. This tendon, is called the posterior tibial tendon, and is the main arch supporting tendon. Obviously damage to this tendon can cause collapse of the arch. Some people have genetically inefficient tendon, and tends to be the case in younger people. In mild cases, such as tendon splits, the posterior tibial tendon can be repaired to restore its strength. Acute incontinuity of the tendon can be primarily repaired. Often the posterior tibial tendon is augmented with a tendon transfer of an adjacent tendon to provide both strength and continuity. In any tendon repair, advanced or retensioning of the tendon is performed. In most flat foot surgery a tendon augmentation is often combined with other boney procedures to restore structure and balance to the foot.


Prevention
Warm up properly. This means not only stretching prior to a given athletic event, but a gradual rather than sudden increase in volume and intensity over the course of the training season. A frequent cause of plantar fasciitis is a sudden increase of activity without suitable preparation. Avoid activities that cause pain. Running on steep terrain, excessively hard or soft ground, etc can cause unnatural biomechanical strain to the foot, resulting in pain. This is generally a sign of stress leading to injury and should be curtailed or discontinued. Shoes, arch support. Athletic demands placed on the feet, particularly during running events, are extreme. Injury results when supportive structures in the foot have been taxed beyond their recovery capacity. Full support of the feet in well-fitting footwear reduces the likelihood of injury. Rest and rehabilitation. Probably the most important curative therapy for cases of plantar fasciitis is thorough rest. The injured athlete must be prepared to wait out the necessary healing phase, avoiding temptation to return prematurely to athletic activity.

Stretching Exercises
Strength training and stretching can help avoid injury and keep your feet free from pain. Stretching should focus on the bottom of your foot to loosen tissues and tight ligaments surrounding your arch. The easiest way to do this is by grabbing a towel and sitting on the floor. You can do this while you catch up on the news in the morning, or when you get home from work. Put one leg out in front with your foot flexed up. Loop the towel around the ball of your foot and gently pull your toes towards you. Hold for thirty seconds and then repeat 3-4 times before switching feet.
