A cavus or high-arched foot may have many foot shapes. This may range from an arch that is slightly high to a severe deformity that causes a patient to walk on the outside of the foot. Surgery is occasionally required to realign the foot. There are different causes of a high-arched foot. In many cases, the cause is unknown. In other cases, the cause is a nerve disease, clubfoot or injury. Treatment ranges from changes in shoewear to surgeries, depending on the amount of deformity and related problems.
The plantar fascia is a thick, fibrous band which runs along the sole of the feet. It helps to support the foot arches and transmits forces through the foot as you move. Plantar fasciitis is one of the most common causes of foot arch pain. The most common problem to develop here is plantar fasciitis. If there is too much strain on the plantar fascia (e.g. from long periods on your feet, suddenly increasing activity levels or your foot position is altered), the plantar fascia becomes inflamed and swollen. It is often accompanied by a bone spur, excess growth of the bone which develops due to repeated tension on the area where the plantar fascia attaches to the bone. Plantar fasciitis is one of the most common causes of foot arch pain. It is usually painful after activity or prolonged rest e.g. first thing in the morning. A less common problem with the plantar fascia which casues foot arch pain is plantar fibromatosis. This is when a small nodular growth develops on the plantar fascia, usually in the middle of the foot arch. It often causes pain when walking due to pressure through the lump.
Most flat feet do not cause pain or other problems. Children may have foot pain, ankle pain, or lower leg pain. They should be evaluated by a health care provider if this occurs. Symptoms in adults may include tired or achy feet after long periods of standing or playing sports.
A professional therapist may use tinels test to diagnose tarsal tunnel syndrome. This involves tapping the nerve just behind the medial malleolus or bony bit of the ankle with a rubber hammer. Pain indicates a positive test. Sometimes it is initially mistaken for plantar fasciitis which also causes pain from the inside heel and throughout the arch of the foot. Neural symptoms (such as tingling or numbness) as well as the location of tenderness when touching the area should help to easily distinguish between the conditions.
Non Surgical Treatment
Consult a doctor to diagnose the condition and determine the cause. If revealed to be plantar fasciitis, please refer to our article on that injury for further information. Generally arch pain is easy to treat, with the most effective method of treatment being the placement of arch supports in the shoes. This counteracts the strain placed on the arches by biomechanical errors, causing them to cease stretching excessively. A specialist can recommend the inserts suitable to your needs, which will depend on the shape of your arches. These supports should lessen your symptoms within days. If pain is severe you should refrain from running activities until it subsides to avoid risking an aggravation of the injury. To maintain fitness, alter your training program temporarily to be focused on low-impact sports like swimming. Applying ice to the affected area should assist in reducing pain and swelling.
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.
People with flexible feet who develop fallen arches may benefit from foot strengthening exercises, notes the Nicholas Institute of Sports Medicine and Athletic Trauma. Standing on a towel in bare feet and grasping the material with the toes is an easy foot-strengthening exercise that can be done at home. Standing on one leg while arching and releasing the foot may also prove useful. Doctors may prescribe gentle stretching exercises for the foot and ankle tendons.
