A heel spur is caused by the displacement of calcium on the bone that forms on the underside of the heel, it may be one small bony protrusion or a collection of tiny, irregularly shaped growths on the bone of the heel, which is called the calcaneum. Heel spurs are sometimes painful, described as a knife digging into the heel and other times, a heel spur goes unnoticed and is only detected by an X-ray.
Heel spurs are bony outgrowths positioned where the plantar fascia tissue attaches to the heel bone (the calcaneus). Heel spurs seldom cause pain. It is the inflamed tissue surrounding the spur that causes the pain. The Latin meaning of Plantar Fasciitis is, ?Inflammation of Plantar Fascia.? The plantar fascia is a long, thick and very tough band of tissue beneath your foot that provides arch support. It also connects your toes to your heel bone. Each time you take a step, the arch slightly flattens to absorb impact. This band of tissue is normally quite strong and flexible but unfortunately, circumstances such as undue stress, being overweight, getting older or having irregularities in your foot dynamics can lead to unnatural stretching and micro-tearing of the plantar fascia. This causes pain and swelling at the location where the plantar fascia attaches to the heel bone. As the fascia continually pulls at the heel bone, the constant irritation eventually creates a bony growth on the heel. This is called a heel spur.
More often than not, heel spurs have no signs or symptoms, and you don?t feel any pain. This is because heel spurs aren?t pointy or sharp pieces of bone, contrary to common belief. Heel spurs don?t cut tissue every time movement occurs; they?re actually deposits of calcium on bone set in place by the body?s normal bone-forming mechanisms. This means they?re smooth and flat, just like all other bones. Because there?s already tissue present at the site of a heel spur, sometimes that area and the surrounding tissue get inflamed, leading to a number of symptoms, such as chronic heel pain that occurs when jogging or walking.
Your doctor will discuss your medical history and will examine your foot and heel for any deformities and inflammation (swelling, redness, heat, pain). He/she will analyze your flexibility, stability, and gait (the way you walk). Occasionally an x-ray or blood tests (to rule out diseases or infections) may be requested.
Non Surgical Treatment
There are many ways to treat heel spurs. Some remedies you can even do at home once a podiatrist shows you how. Heel spur treatment is very similar to treatment of plantar fasciitis. Here are a few of the most common treatments. First, your doctor will assess which activities are causing your symptoms and suggest rest and time off from these activities. Ice packs are used to control pain and reduce symptoms. Certain exercises and stretches help you to feel relief quickly. Medications that reduce inflammation and decrease pain are also used. Sometimes cortisone injections are given. Often special shoe orthotics can help to take the pressure off of the plantar fascia and reduce symptoms. Night splints that keep your heel stretched are sometimes recommended. Rarely, surgery is an option. A new treatment called extracorporeal shock wave therapy is being studied.
Most studies indicate that 95% of those afflicted with heel spurs are able to relieve their heel pain with nonsurgical treatments. If you are one of the few people whose symptoms don?t improve with other treatments, your doctor may recommend plantar fascia release surgery. Plantar fascia release involves cutting part of the plantar fascia ligament in order to release the tension and relieve the inflammation of the ligament. Sometimes the bone spur is also removed, if there is a large spur (remember that the bone spur is rarely a cause of pain. Overall, the success rate of surgical release is 70 to 90 percent in patients with heel spurs. One should always be sure to understand all the risks associated with any surgery they are considering.
If you have not yet developed this condition, you can take steps to protect yourself from it. Most importantly, make it a rule to wear properly fitted footwear. Avoid shoes that have become worn down in the heel, and don't choose shoes that cause you to walk in an abnormal fashion. Maintaining a healthy weight will ensure that undue pressure isn't being put on the ligaments, tendons and bones of your feet. If your job requires a great deal of time on your feet, or if you exercise regularly, be sure to balance periods of activity with periods of rest for your feet.
