A heel spur is a bony projection on the sole (bottom) of the heel bone. This condition may accompany or result from severe cases of inflammation to the structure called plantar fascia. The plantar fascia is a fibrous band of connective tissue on the sole of the foot, extending from the heel to the toes. Heel spurs are a common foot problem resulting from excess bone growth on the heel bone. The bone growth is usually located on the underside of the heel bone, and may extend forward toward the toes. A painful tear in the plantar fascia between the toes and heel can produce a heel spur and/or inflammation of the plantar fascia. Because this condition is often correlated to a decrease in the arch of the foot, it is more prevalent after the ages of six to eight years, when the arch is fully developed.
A strong band of sinew (plantar fascia) stretches across the sole of the foot below the surface of the skin and is attached to a point in the middle of the under surface of the heel bone. With repeated activity on our feet, the plantar fascia can become tight and cause persistent traction (tugging) on its attachment point into the heel bone, and inflammation and pain may develop at this site. This painful condition is known as plantar fasciitis. Sometimes a ?spur? develops at the site of this traction on the bone and protrudes into the surrounding tissue. This is a heel spur.
The vast majority of people who have heel spurs feel the asscociated pain during their first steps in the morning. The pain is quite intense and felt either the bottom or front of the heel bone. Typically, the sharp pain diminishes after being up for a while but continues as a dull ache. The pain characteristically returns when first standing up after sitting for long periods.
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
Initially, treatment usually consists of a combination of ice therapy, stretching exercises to improve flexibility (especially in the mornings), anti-inflammatory medications, and physical therapy. Most patients will also need custom-molded orthotics to help control the motion in the foot and arch, which takes the strain off the plantar fascia. If the pain continues, a cortisone injection may be used to calm the severe swelling and pain. There may the need for a night splint to maintain a stretch in the plantar fascia throughout the night.
Surgery to correct for heel spur syndrome is a common procedure which releases plantar fascia partially from its attachment to the calcaneous (heel bone). This part of the surgery is called a plantar fasciotomy due to the fact the fascia is cut. This is most often done through an open procedure as any heel spur or bursa can be removed at the same time. If the spur is not removed during the surgery, it will probably be just as successful, as the large spur is not the true problem. Some physicians use an endoscopic approach (EPF) where a small camera aids the physician during surgery with typically smaller incisions on each side of your foot.
In 2002, researchers attempted to compare the effects of various running techniques on pronation and resulting injuries like stress fractures and heel spurs. They suggested that it is possible to teach runners to stride in such a way as to minimize impact forces. One way is to lower running speed. Another is to take longer rest periods following a run.
