    What are Heel Spurs?

    Heel spurs are bony growths from the underside of the front part of the heel bone, the calcaneus. They are believed to be formed by stretching and tearing of the fibrous band supporting the arch of the foot, the plantar fascia, and tearing away of the lining of the heel bone where the fibrous band connects. New bone can grow in the areas where the bone’s lining has been torn away. These growths of new bone are called heel spurs and are visible by x-ray. In most cases, it is not the spur that causes heel pain.

    Heel pain can be present with or without evidence of a heel spur on x-ray of the foot. The same stretching and tearing that can lead to the formation of a spur causes microtears and degeneration of the plantar fascia, the long fibrous band that connects the heel to the ball of the foot and supports the longitudinal arch. The resulting inflammation, called plantar fasciitis, makes the area painful after periods of rest which allow the fascia to heel in a relaxed, rather than in a flexed position.

    What causes heel spurs or plantar fasciitis?

    Heel pain attributed to plantar fasciitis is generally due to too much stress on the heel and the soft tissues connecting to it, including the plantar fascia. Several factors can contribute to the amount of stress placed on the tissues. · Foot deformity causing faulty biomechanics - flattened arch, high-arch, or gait abnormalities can cause abnormal distribution of weight during activities, stressing the plantar fascia.

    · Weight bearing activity - especially activities on hard, unyielding surfaces including exercise (walking, jogging, tennis) or work (waitressing, work involving long periods of standing.) Stress on plantar fascia is increased when these activities are performed regularly or when they are begun abruptly after long periods of physical inactivity.

    · Age - as you age, the elasticity of the plantar fascia decreases leading to less arch support. There can also be atrophy of the fat pad covering the heel resulting in decreased shock absorbency.

    · Weight - excess weight causes increased pressure on the feet, leading to increased stress on the plantar fascia.

     · Shoes - thin soles, poor arch support, and poor shock absorbency in footwear can be harmful. Regularly wearing high-heel shoes can lead to shortening of the Achilles’ tendon, which increases the strain on your heels and fascia when you change to a flatter shoe.

    How do I know if I have plantar fasciitis ?

     People with plantar fasciitis typically describe "pain with the first step in the morning" that feels like a knife stabbing their heel. The pain usually decreases with time and activity and is characterized by "restart pain" after prolonged sitting. There may also be some activity related discomfort throughout the day. Most people experience the pain in only one foot, although it can occur in both. There is usually no specific traumatic event related to the onset of the pain.

    How does my doctor find out if I have plantar fasciitis ?

    Your physican will be able to diagnose plantar fasciitis on the basis of the symptoms you are experiencing and by examining your foot to detect areas that are painful to the touch. Typically, pain is illicited in the area at the front of the calcaneus where the plantar fascia inserts, and along the inner border of the sole of the foot when it is flexed upward (dorsiflexion.) He/she may want to get weight bearing x-rays of your feet to rule out other causes of pain such as a stress fracture, and to look for signs of a heel spur or fat pad atrophy. Your symptoms and the examination will aslo help to rule out conditions such as rheumatoid arthritis, bursitis, a neuroma, or bone/stone bruises that can aslo cause heel pain.

    How is plantar fasciitis treated ?

    The goal of treatment is to heal tears, decrease inflammation of the fascia and to prevent recurrences. The course of heeling is slow, typically 6-12 months, and usually begins with conservative treatment that you or your physician can intiate.
     

    Treatment you can do yourself:

    · Stretch- stretch your plantar fascia, Achilles’ tendon and calf muscles daily, especially before getting out of bed in the morning, to increase their flexibility and relieve the tightening that occurs overnight.

    · Choose alternative activities - decrease the amount of running, jogging, or walking and choose activities that put less weight on you heel such as bicycling or swimming.

    · Ice - apply ice to the area for up to 20 minutes after acitivty.

    · Strengthen - exercises to strengthen the muscles in your foot can help support your arch.

    · Shoes - wear appropriate, well supporting shoes, with low to moderate heels, and good shock absorbency.

    · Pain relievers - you can try over-the-counter (OTC) medications for the pain, use as directed on packaging, and taper their use as your pain is relieved.

    · Weight loss - if you are overweight, losing the excess pounds will decrease the amount of pressure on your feet.

    · Additional Support - you can try heel pads or cups to supplement the support and cushion of your shoes. There are several products availabe at medical supply, shoe and drug stores.

    Consult your doctor: if the pain if not relieved by self treatment or if you think that you have a foot deformity contributing to the heel pain.

    · Correction of foot deformity - using a custom/manufactured orthotic device (shoe insert) prescribed by your doctor.

    · Prescription pain relievers/anti-inflammatories - similar to OTC medications but require a doctors supervision for use due to side effects, especially gastrointestinal irritation.

    · Night splints - devices worn at night that maintain a flexed foot position to keep the plantar fascia stretched.

    · Corticosteroid injections - may help relieve inflammation when other steps aren’t successful. Like all injections they have the risk of infection and bleeding. More importantly, repeated injections are not recommended due to the risk of weakening the plantar fascia and promoting atrophy of the fat pad covering the heel.

    · Surgery - very rarely indicated. Involves releasing the plantar fascia from the heel bone. Side effects include continued pain and weakening of the arch. As in all surgical procedures, there is a risk of infection, bleeding, and scarring.
