Flexible flatfeet are considered normal in young children because babies are not born with a normal arch. The arch may not form fully until sometime between ages 7 and 10. Even in adulthood, 15% to 25% of people have flexible flatfeet. Most of these people never develop symptoms. In many adults who have had flexible flatfeet since childhood, the missing arch is an inherited condition related to a general looseness of ligaments. These people usually have extremely flexible, very mobile joints throughout the body, not only in the feet. Flatfeet also can develop during adulthood. Causes include joint disease, such as rheumatoid arthritis, and disorders of nerve function (neuropathy).
A common cause of foot arch pain is a stress fracture. They tend to occur from repeated overloading of one of the foot bones from activities such as jumping and running especially if you have suddenly increased your activity level. The breaks in the bone may be small but they can be extremely painful. Stress fractures of the metatarsal bones or the navicular can cause anything from mild to severe foot arch pain. The Tibialis Posterior muscle plays a very important role in supporting the medial arch of the foot. Posterior Tibial Tendonitis can occur either through repetitive use e.g. high impact sports such as soccer or tennis, or from an injury e.g. a fall. This causes the tendon to become inflamed or even torn, resulting in pain on bottom of foot. This pain usually gets worse with activity or when standing for long periods. If the problem persists, the inner side of the foot (known as the medial longitudinal arch of the foot) gradually collapses down, causing flat feet. A simple test for this condition is to stand on one leg and rise up onto your tiptoes. If you cannot, it indicates a problem with the Posterior Tibial tendon. Treatment usually consists of rest, ice, exercises, orthotics and physical therapy.
Repetitive exertive activity arch pain is usually sharp, and localized to a specific area, rather than the entire arch. Usually the pain occurs in the area just in front of the heel. It is present when first standing on the foot in the morning, but may decrease once you start walking around, but will, gradually becomes worse with continued walking or running. Swelling may be present. The pain subsides with rest, but stretching the arch while resting may cause the pain to return. Injury pain is constantly present, but worse when standing on the foot. This pain is localized to a specific area, but may radiate out from this area to the entire foot. The pain is sharp, and usually accompanied by swelling and occasionally "black and blue" discolorations. The pain due to the natural aging process is usually dull and aching, or stiff, and can be felt throughout the entire arch area, rather then in just one spot. This pain is present whenever weight bearing, and usually becomes worse with continued walking. The pain gradually subsides when resting, and usually does not return with stretching. Biomechanical defect pain is usually localized to a section of the arch, such as the inner, middle, outer, front, or back of the arch. This pain may be sharp or dull, but is always worse with continued walking.
To come to a correct diagnosis, your podiatrist will examine your foot by using his or her fingers to look for a lump or stone bruise in the ball of your foot. He or she will examine your foot to look for deformities such as high or low arches, or to see if you have hammertoes. He or she may use x-rays, MRIs (magnetic resource imaging), and CT scans to rule out fractures and damage to ligaments, tendons, and other surrounding tissues. Your doctor will also inquire about your daily activities, symptoms, medical history, and family history. If you spend a lot of time running or jumping, you may be at a higher risk for pain in the bottom of your foot. These diagnostic tests will help your doctor come to a proper diagnosis and create an appropriate treatment plan.
Non Surgical Treatment
Stretch the fascia. Prop your toes up against a wall, keeping your arch and heel flat so the toes stretch. Hold for a count of 10. Repeat 10 times three or four times per day. Roll a frozen water bottle under the arch. Stretch first then roll out the arch for 10 minutes; you don?t want to stretch the tendon when it?s ice cold. Freeze a golf ball and massage the fascia. Roll the frozen golf ball under the foot, starting from the front and working your way back. Put good pressure on each spot-the medial, center and lateral positions-for 15 seconds before moving to the next area. Then, roll the ball back and forth over the entire foot. Foam roll all muscles on the body above the plantar. Even tight shoulders can cause the condition, as your arm swing can throw off proper hip alignment and footstrike. Bump your arch. Get a commercial insole with an arch bump to push on the plantar and keep it from flexing-it doesn?t matter if you?re an under or overpronator; the plantar needs to be supported and strengthened, Wear the support in all shoes, if possible.
The main goal of surgery is to reduce pain and improve function. It may also reduce other injuries such as repeated ankle sprains and broken bones. Surgery may be considered if there is no relief with physical therapy, changes in shoewear and/or changes in activity. Some patients will also have tendon problems, ankle weakness and foot fractures. These patients may require other procedures to address related problems. If you have medical problems that make surgery unsafe, any infections or blood vessel disease, cavus foot surgery may not be appropriate. The surgical procedures involved with the correction of the cavus foot are varied. Theses may include correction of the bony deformity, ankle looseness and the muscle imbalances that cause the deformity. The goal is to provide a foot that evenly distributes weight along both inside and outside edges. A variety of incisions may be needed to perform the procedures related to the correction of the cavus foot.
Stretch and strengthen important muscles in your feet, ankles and legs in order to guard against future strain. Make sure to acquire suitable arch supports and inserts if necessary, and that your shoes are shock absorbent and in good condition. Wearing tattered shoes provides no protection, and runners should replace their footwear before exceeding 500 miles of usage. Athletes new to arch supports should gradually build their training routine, allowing their feet to become accustomed to a new stance.
