Heel Spurs should be called a traction spurs because they grow in the same direction that the tendons pull away from the heel bone, which is why it can occur on the bottom of the heel (Plantar Fasciitis) and on the back of the heel (Achilles Tendonitis). Some patients may only develop one type of heel spur, but both these problems are closely related so it’s not unusual for a patient to have both heel spurs. It’s important to note though that most heel spurs aren’t the cause of your heel pain.
Generally caused by lack of flexibility in the calf muscles and/or excess weight, heel spurs occur when the foot bone is exposed to constant stress and calcium deposit build-up on the bottom of the heel bone. Repeated damage can cause these deposits to pile up on each other, presenting a spur-shaped deformity.
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
The key for the proper treatment of heel spurs is determining what is causing the excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rear foot posting and longitudinal arch support is an effective device to reduce the over-pronation, and allow the condition to heal. Other common treatments include stretching exercises, losing weight, wearing shoes that have a cushioned heel that absorbs shock, and elevating the heel with the use of a heel cradle, heel cup, or orthotic. Heel cradles and heel cups provide extra comfort and cushion to the heel, and reduce the amount of shock and shear forces experienced from everyday activities.
Usually, heel spurs are curable with conservative treatment. If not, heel spurs are curable with surgery, although there is the possibility of them growing back. About 10% of those who continue to see a physician for plantar fascitis have it for more than a year. If there is limited success after approximately one year of conservative treatment, patients are often advised to have surgery.
