A 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." Although heel spurs are often painless, they can cause heel pain. They are frequently associated with plantar fasciitis, a painful inflammation of the fibrous band of connective tissue (plantar fascia) that runs along the bottom of the foot and connects the heel bone to the ball of the foot. Treatments for heel spurs and associated conditions include exercise, custom-made orthotics, anti-inflammatory medications, and cortisone injections. If conservative treatments fail, surgery may be necessary.
The pain caused by heel spurs can be a sharp, stabbing pain when using the foot after a long period of rest. Sometimes it then reduces to a dull throb that can worsen when engaging in activities like jogging or jumping. People sometimes describe the pain of heel spurs and plantar fasciitis as a pin sticking into the bottom of the foot when they first stand up in the morning, this pain later turns into a bearable ache. The cause of the pain is generally not the heel spur itself, but the soft-tissue buildup associated with it. People often complain that the sharp pain returns after they stand up following sitting for a prolonged period of time.
Heel spur and plantar fasciitis pain usually begins in the bottom of the heel, and frequently radiates into the arch. At times, however, the pain may be felt only in the arch. The pain is most intense when first standing, after any period of rest. Most people with this problem experience their greatest pain in the morning, with the first few steps after sleeping. After several minutes of walking, the pain usually becomes less intense and may disappear completely, only to return later with prolonged walking or standing. If a nerve is irritated due to the swollen plantar fascia, this pain may radiate into the ankle. In the early stages of Heel Spurs and Plantar Fasciitis, the pain will usually subside quickly with getting off of the foot and resting. As the disease progresses, it may take longer periods of time for the pain to subside.
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. The plantar fascia is the 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. In other words, tremendous stress is placed on the plantar fascia.
Non Surgical Treatment
Heel spurs can be treated by wearing orthotic insoles inside the shoe. Orthotics are designed to correct incorrect gait, in particular over-pronation (rolling in of the foot and collapsing of the arches). Over-pronation is a very common foot condition, affecting at least half of the population. It is a major contributing cause of heel spurs. Orthotics are very effective in that the device corrects the foot to its natural position. By supporting the arches properly and preventing excess rolling in of the foot, the plantar fascia is placed under much less strain and stress compared to an unsupported foot. Less strain on the ligament means less pulling away from the heel bone, allowing the inflammation to heal faster. In addition to orthotic treatment, most podiatrists and physiotherapists recommend a series of exercises to help make the ligaments in the feet and legs longer and more flexible. In turn this will help reduce strain on the plantar fascia.
Sometimes bone spurs can be surgically removed or an operation to loosen the fascia, called a plantar fascia release can be performed. This surgery is about 80 percent effective in the small group of individuals who do not have relief with conservative treatment, but symptoms may return if preventative measures (wearing proper footwear, shoe inserts, stretching, etc) are not maintained.
