Heel spurs are tiny protruding calcium deposits that can develop near the base of your heel bone. They can be caused by repetitive activities, such as dancing or running, or they can form in association with plantar fasciitis, which is an inflammation of the ligament (plantar fascia) on the bottom of your foot. When the plantar fascia is tight and pulls on your heel bone, the bone releases calcium to try to heal itself. The excess deposits of calcium can sometimes form heel spurs.
A bone spur forms as the body tries to repair itself by building extra bone. It generally forms in response to pressure, rubbing, or stress that continues over a long period of time. Some bone spurs form as part of the aging process. As we age, the slippery tissue called cartilage that covers the ends of the bones within joints breaks down and eventually wears away (osteoarthritis). Bone spurs due to aging are especially common in the joints of the spine and feet.
Heel spur is characterised by a sharp pain under the heel when getting out of bed in the morning or getting up after sitting for a period of time. Walking around for a while often helps reduce the pain, turning it into a dull ache. However, sports, running or walking long distance makes the condition worse. In some cases swelling around the heel maybe present.
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
In many cases treatment is non-surgical and can relieve pain, but may take from three months to a year to fully recover. Performing stretching exercises to help relax the tissues in the heel as well as rest, icing, and over-the-counter anti-inflammatory or prescription medications can help ease symptoms. Customized orthotics or shoe inserts to position and cushion your heel can help.
Surgery involves releasing a part of the plantar fascia from its insertion in the heel bone, as well as removing the spur. Many times during the procedure, pinched nerves (neuromas), adding to the pain, are found and removed. Often, an inflamed sac of fluid call an accessory or adventitious bursa is found under the heel spur, and it is removed as well. Postoperative recovery is usually a slipper cast and minimal weight bearing for a period of 3-4 weeks. On some occasions, a removable short-leg walking boot is used or a below knee cast applied.
