Plantar fasciitis is the most common cause of heel pain, accounting for around four out of five cases. Plantar fasciitis is when the thick band of tissue that connects the heel bone with the rest of the foot (the plantar fascia) becomes damaged and thickened. Damage to the plantar fascia is thought to occur following, sudden damage - for example, damaging your heel while jogging, running or dancing; this type of damage usually affects younger people who are physically active, gradual wear and tear of the tissues that make up the plantar fascia - this usually affects adults who are 40 years of age or over.
There are many causes of heel pain. However, plantar fasciitis, also known as heel spur syndrome, is the most common, by far. The pain is usually localized to the bottom of the heel towards the inside of the foot. The arch may also be painful. With this condition, pain is typically most severe with the first few steps after a period of rest. The pain my then subside and then return after extended periods of standing. There is usually no specific traumatic event that is responsible for the condition. It is usually the result of overuse, e.g. too much standing, walking or running. There are several common contributory factors such as weight gain, foot type, shoes. Flat shoes or going barefoot are the worst. Athletic shoes are usually the best. The plantar fascia is a fibrous band or ligament that connects the ball of the foot with the heel and helps to support the arch. When this band gets stretched too much or overused, inflammation results, often at the location where it attaches to the heel bone. A heel spur may develop as a result of chronic pulling by the plantar fascia. However, it should be noted that the pain is not caused by the spur. In fact, in some of the most severe cases, there is no spur at all. In other instances, an X-ray may be taken for an unrelated condition and an extremely large but non-painful spur may be seen. Other causes of heel pain include gout, stress fracture, bone tumors, nerve entrapment and thinning of the fat pad beneath the heel. Pain at the back of the heel is usually not plantar fasciitis. (Pain at the back of the heel is often due to an inflammation of the Achilles tendon, enlargement of the heel bone or bursitis.)
Sever?s Disease. This is a condition that occurs in 10 - 15 year old children, predominantly boys and is associated with running and repetitive jumping. It is also associated with flimsy footwear that kids may wear. It occurs when the Achilles tendon continually pulls on the apophysis of the calcaneum and does not allow for it to fuse with the body of the calcaneum. Calcaneal enthesopathy. This occurs when there is repetitive trauma at the attachment of the Achilles tendon, resulting in a spur from the calcaneum up into the Achilles tendon. It is usually visualized on x-ray and may be tender if there is an associated bursitis or tendonitis. "Pump Bump". Also known as Haglund?s Deformity, this is a bony enlargement that exists on the back of the heel - usually related to a congenital abnormality or with chronic bursitis, causing a thickening. There may have already been trauma or pressure from footwear. Treatment is usually protection of the bump and correct footwear. Associated with a symmetrical swelling at the base of the Achilles tendon. It is usually related to repetitive trauma or inappropriate footwear. It is often red and hot in the early stages. Treatment is usually to correct the footwear, provide padding and treat the local symptoms e.g. ice, rest, physiotherapy and cortisone injection. Fat Pad Syndrome. Direct contact with the base of the heel may result in trauma to the fat pad. Related to obesity, training on hard surfaces, uneven grounds, poor shoes especially overlarge shoes which can cause shearing forces on the heel. These conditions are renowned for taking a long time to recover - usually many months.
To arrive at a diagnosis, the foot and ankle surgeon will obtain your medical history and examine your foot. Throughout this process the surgeon rules out all the possible causes for your heel pain other than plantar fasciitis. In addition, diagnostic imaging studies such as x-rays or other imaging modalities may be used to distinguish the different types of heel pain. Sometimes heel spurs are found in patients with plantar fasciitis, but these are rarely a source of pain. When they are present, the condition may be diagnosed as plantar fasciitis/heel spur syndrome.
Non Surgical Treatment
Treatment for plantar fasciitis should be directed at resting the plantar fascia, providing support for the arch area and limiting pronation. This is often accomplished with the use of supportive strapping with athletic tape, arch supports and orthotics. Heel lifts may also be helpful. Anti-inflammatories, pills as well as cortisone injections, may be effective as an adjunctive treatment by speeding up the reduction of inflammation. However, if used alone, anti-inflammatories rarely lead to resolution of the condition. Stretching exercises, physical therapy and night splints may also be helpful. The majority of cases respond to non-surgical treatment although it may take several weeks to reach a comfortable level. In those cases that do not respond adequately to conservative measures, surgical release of the plantar fascia may be considered. However, a new non-surgical treatment called Extracorporeal Shockwave Therapy (ESWT) is now available as an option for recalcitrant plantar fasciitis. ESWT was approved by the FDA recently for the treatment of chronic heel pain. It has been in use for several years on thousands of patients in Europe and has been successfully used to restore patients with chronic plantar fasciitis to a normal, active lifestyle. ESWT is a non-invasive procedure that uses high intensity sound waves similar to what is routinely used to treat kidney stones. The treatment is usually performed in the office or in an outpatient surgical center. The procedure is performed under local anesthesia and takes about 25 minutes. The shockwaves are directed at the plantar fascia and stimulate an inflammatory healing response.
When a diagnosis of plantar fasciitis is made early, most patients respond to conservative treatment and don?t require surgical intervention. Often, when there is a secondary diagnosis contributing to your pain, such as an entrapped nerve, and you are non-responsive to conservative care, surgery may be considered. Dr. Talarico will discuss all options and which approach would be the most beneficial for your condition.
Heel pain is commonly caused from shoes that do not fit properly. In addition, shoes need to have ample cushioning and support, particularly through the heel, ball of the foot, and arch. Shoes should also be replaced if they become too worn. One sure sign of wear and tear is overly worn areas of a shoe's insoles. If the heel or ball of the foot is particularly worn, damage could easily occur since the bottom of the foot is not getting the cushioning it needs.
