Patients and doctors often confuse the terms heel spur and plantar fasciitis. While these two diagnoses are related, they are not the same. Plantar fasciitis refers to the inflammation of the plantar fascia--the tissue that forms the arch of the foot. A heel spur is a hook of bone that can form on the heel bone (calcaneus) and is associated with plantar fasciitis.

About 70 percent of patients with plantar fasciitis have a heel spur that can be seen on an X-ray.


However, many patients without symptoms of pain can have a heel spur. The exact relationship between plantar fasciitis and heel spurs is not entirely understood.

Heel spurs are common in patients who have a history of foot pain caused by plantar fasciitis. In the setting of plantar fasciitis, heel spurs are most often seen in middle-aged men and women, but can be found in all age groups. The heel spur itself is not thought to be the primary cause of pain, rather inflammation and irritation of the plantar fascia is thought to be the primary problem. A heel spur diagnosis is made when an x-ray shows a hook of bone protruding from the bottom of the foot at the point where the plantar fascia is attached to the heel bone.

Pain in the Heel

The plantar fascia is a thick connective tissue that runs from the calcaneus (heel bone) to the ball of the foot. This strong and tight tissue helps maintain the arch of the foot. It is also one of the major transmitters of weight across the foot as you walk or run.

That's why tremendous stress is placed on the plantar fascia.

When a patient has plantar fasciitis, the plantar fascia becomes inflamed and degenerative (worn out)--these abnormalities can make normal activities quite painful. Symptoms typically worsen early in the morning after sleep. At that time, the plantar fascia is tight so even simple movements stretch the contracted plantar fascia. As you begin to loosen the plantar fascia, the pain usually subsides, but often returns with prolonged standing or walking.

Heel spurs form in some patients who have plantar fasciitis, and tend to occur in patients who have had the problem for a prolonged period of time. While about 70 percent of patients with plantar fasciitis have a heel spur, x-rays also show about 50 percent of patients with no symptoms of plantar fasciitis also have a heel spur.

Treatment of Heel Spurs

Treatment of heel spurs is the same as treatment of plantar fasciitis. Because these problems are related, the treatment is the same. The first step in the treatment of a heel spur is short-term rest and inflammation control. Here are the steps patients should take in order to cure the symptoms of plantar fasciitis and heel spurs.
