The term heel spur generally refers more specifically to a heel spur, also known as a calcaneal spur. These calcium growths form around the tendons and ligaments of the foot and eventually become attached to the heel bone. The spurs then continue to grow, piercing the skin of the foot and causing pain and discomfort. When left untreated the spur can continue to grow causing agonizing pain and even immobilizing the patient.
Bone spurs form in the feet in response to tight ligaments, to activities such as dancing and running that put stress on the feet, and to pressure from being overweight or from poorly fitting shoes. For example, the long ligament on the bottom of the foot (plantar fascia) can become stressed or tight and pull on the heel, causing the ligament to become inflamed (plantar fasciitis). As the bone tries to mend itself, a bone spur can form on the bottom of the heel (known as a ?heel spur?). Pressure at the back of the heel from frequently wearing shoes that are too tight can cause a bone spur on the back of the heel. This is sometimes called a ?pump bump,? because it is often seen in women who wear high heels.
Most people think that a bone "spur" is sharp and produces pain by pressing on tissue, when in fact, these bony growths are usually smooth and flat. Although they rarely cause pain on their own, bone spurs in the feet can lead to callus formation as tissue builds up to provide added cushion over the area of stress. Over time, wear and tear on joints may cause these spurs to compress neighboring ligaments, tendons or nerves, thus injuring tissue and causing swelling, pain and tearing.
A heel spur is often seen on X-ray as a bony protrusion, which can vary in size. However, because a Heel Spur only indicates increased load on the plantar fascia, and not pain, an ultra sound may be required to assess other actual cause of the heel pain such and may include checking to see if the plantar fascia is inflamed or degenerated.
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.
In a small number of cases (usually less than 5 percent), patients may not experience relief after trying the recommendations listed above. It is important that conservative treatments (such as those listed above) be performed for AT LEAST a year before considering surgery. Time is important in curing the pain from heel spurs, and insufficient treatment before surgery may subject you to potential complications from the procedure. If these treatments fail, your doctor may consider an operation to loosen the plantar fascia, called a plantar fascia release.
Walk around before you buy shoes. Before you purchase your shoes, do the following. Re-lace the shoes if you're trying on athletic shoes. Start at the farthest eyelets and apply even pressure to the laces as you come closer to the tongue of the shoe. Make sure that you can wiggle your toes freely inside of the shoe. Also, make sure that you have at enough space between your tallest toe and the end of the shoe. You should have room equal to about the width of your thumb in the tip of your shoe. Walk around to make sure that the shoe has a firm grip on your heel without sliding up and down. Walk or run a few steps to make sure your shoes are comfortable. Shoes that fit properly require no break-in period.
