Overview
The two most common causes of pain in the bottom of the heel, the arch, or both the heel and the arch, are heel spurs and plantar fasciitis. A Heel Spur is a piece of calcium or bone that sticks out from the bottom of the heel bone, and lies within the fibers of the plantar fascia. When walking, the spur digs into the plantar fascia and causes small micro-tears in the plantar fascia. This produces inflammation and pain in the heel, which at times may radiate into the arch.
Causes
This condition is a constellation of many causes; overweight, ill fitting shoes, bio-mechanical problems (mal-alignment of the heel), gout, pronation (a complex motion including outward rotation of the heel and inward rotation of the ankle) and rheumatoid arthritis are some of the causes of heel pain.
Symptoms
With heel spurs, people often talk about a dull ache which is felt most of the time with episodes of a sharp pain in the center of the heel or on the inside margin of the heel. Often the pain is worse on first rising in the morning and after rest and is aggravated by prolonged weight bearing and thin-soled shoes.
Diagnosis
The proper diagnosis of a heel spur often requires an X-ray. To make this process as convenient for his patients as possible, most clinics have an on-site digital X-ray and diagnostic ultrasound machines. This can make it unnecessary for patients to visit diagnostic imaging centers, allowing patients to receive more expedient treatment.
Non Surgical Treatment
Heel spurs and plantar fascitis are usually controlled with conservative treatment. Early intervention includes stretching the calf muscles while avoiding re-injuring the plantar fascia. Decreasing or changing activities, losing excess weight, and improving the proper fitting of shoes are all important measures to decrease this common source of foot pain. Modification of footwear includes shoes with a raised heel and better arch support. Shoe orthotics recommended by a healthcare professional are often very helpful in conjunction with exercises to increase strength of the foot muscles and arch. The orthotic prevents excess pronation and lengthening of the plantar fascia and continued tearing of this structure. To aid in this reduction of inflammation, applying ice for 10-15 minutes after activities and use of anti-inflammatory medication can be helpful. Physical therapy can be beneficial with the use of heat modalities, such as ultrasound that creates a deep heat and reduces inflammation. If the pain caused by inflammation is constant, keeping the foot raised above the heart and/or compressed by wrapping with an ace bandage will help. Corticosteroid injections are also frequently used to reduce pain and inflammation. Taping can help speed the healing process by protecting the fascia from reinjury, especially during stretching and walking.
Surgical Treatment
Heel spur surgery should only be considered after less invasive treatment methods have been explored and ruled insufficient. The traditional surgical approach to treating heel spurs requires a scalpel cut to the bottom of the food which allows the surgeon to access the bone spur. Endoscopic plantar fasciotomies (EPF) involve one or two small incisions in the foot which allow the surgeon to access and operate on the bone spur endoscopically. Taking a surgical approach to heel spur treatment is a topic to explore with a foot and ankle specialist.
Prevention
o help prevent heel and bone spurs, wear properly designed and fitted shoes or boots that provide sufficient room in the toe box so as not to compress the toes. They should also provide cushioning in appropriate areas to minimize the possibility of the irritation and inflammation that can lead to bone spurs in the feet. If needed, use inserts that provide arch support and a slight heel lift to help ensure that not too much stress is placed on the plantar fascia. This helps to reduce the possibility of inflammation and overstress. Wearing padded socks can also help by reducing trauma. Peer-reviewed, published studies have shown that wearing clinically-tested padded socks can help protect against injuries to the skin/soft tissue of the foot due to the effects of impact, pressure and shear forces. Also consider getting your gait analyzed by a foot health professional for appropriate orthotics. If you have heel pain, toe pain or top-of-the-foot pain, see your doctor or foot specialist to ensure that a spur has not developed.
