Heel spur

Heel spur is a calcium deposit causing a bony protrusion on the underside of the heel bone. On an X-ray, a heel spur can extend forward by as much as a half-inch. Without visible X-ray evidence, the condition is sometimes known as "heel spur syndrome."

Causes

Heel spurs are often caused by strains on foot muscles and ligaments, stretching of the plantar fascia, and repeated tearing of the membrane that covers the heel bone. Heel spurs are especially common among athletes whose activities include large amounts of running and jumping.

Risk factors

Risk factors for heel spurs include:

• Walking gait abnormalities, which place excessive stress on the heel bone, ligaments, and nerves near the heel
• Running or jogging, especially on hard surfaces
• Poorly fitted or badly worn shoes, especially those lacking appropriate arch support
• Excess weight and obesity

Symptoms

Although many people with plantar fasciitis have heel spurs, spurs are not the cause of plantar fasciitis pain. One out of 10 people has heel spurs, but only 1 out of 20 people (5%) with heel spurs has foot pain. Because the spur is not the cause of plantar fasciitis, the pain can be treated without removing the spur.

Treatment

Heel spurs can be treated by:

• Physical therapy
• Orthotics
• Anti-inflammatory medications
• Corticosteroid injections
• Surgery
