High arch (cavus foot) is a condition in which the arch on the bottom of the foot that runs from the toes to the heel is raised more than normal. Because of this high arch, excessive weight falls on the ball and heel of the foot when walking or standing causing pain and instability. Children with neurological disorders or other conditions such as cerebral palsy, spina bifida, poliomyelitis, muscular dystrophy are more likely to develop cavus foot. It may sometimes occur as an inherited abnormality.
The most common cause of arch pain is plantar fasciitis. Plantar fasciitis is the name that describes inflammation of the fibrous band of tissue that connects the heel to the toes. Symptoms of plantar fasciitis include pain early in the morning and pain with long walks or prolonged standing. Arch pain early in the morning is due to the plantar fascia becoming contracted and tight as you sleep through the night. When awakening and walking in the morning, the fascia is still tight and prone to irritation when stretched. When walking or standing for long periods, the plantar fascia becomes inflamed and painful. Treatment of plantar fasciitis is best accomplished with some simple stretching exercises, anti-inflammatory medications, and inserts for your shoes.
Plantar fasciitis is most often seen in middle-aged men and women, but can be found in all age groups. The condition is diagnosed with the classic symptoms of pain well focused deep in the heel area of the bottom of the foot. Often the pain from plantar fasciitis is most severe when you first stand on your feet in the morning. Pain often subsides quite quickly, but then returns after prolonged standing or walking. Plantar fasciitis is sometimes, but not always, associated with a rapid gain of weight. It is also sometimes seen in recreational athletes, especially runners. In these athletes, it is thought that the repetitive nature of the sports causes the damage to the fibrous tissue that forms the arch of the foot.
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
Posterior tibial tendon dysfunction is a common cause of fallen arches in adults. The tendon runs along the bottom of the foot and up the back of the ankle, connecting to the tibialis posterior muscle in the calf. The posterior tibial tendon is an important support for the foot arch. Overuse, inflammation and tears of the tendon may cause progressive foot and ankle pain and the development of flat feet. The American College of Foot and Ankle Surgeons states that an ankle brace, leg cast or removable boot may be used to temporarily immobilize the posterior tibial tendon, facilitating healing. Physical therapy typically follows immobilization to strengthen the foot and restore normal foot structure and function.
If you have pain that has not been responsive to other treatments, there is a new non-surgical treatment that was recently approved by the FDA. ESWT (extracorporeal shockwave therapy) uses strong electrohydraulic acoustic (sound) energy that triggers the body?s natural repair mechanism. This treatment method is safe, effective and requires a very short recovery period compared to older surgical techniques.
Early in the treatment of arch pain, consideration needs to be given to the cause and strategies put in place to prevent it happening again. Advice should be sought on the adequacy of footwear. Stretching exercises should be continued long after the symptoms are gone. Foot orthoses should be used if structural imbalances are present. Activity levels and types of activities (occupational and sporting) need to be considered and modified accordingly.
