The heel spur (or calcaneal spur) is a nail-like growth of calcium around the ligaments and tendons of the foot where they attach to the heel bone. The spur grows from the bone and into the flesh of the foot. A heel spur results from an anatomical change of the calcaneus (heel bone). This involves the area of the heel and occasionally, another disability, such as arthritis. The heel bone forms one end of the two longitudinal arches of the foot. These arches are held together by ligaments and are activated by the muscles of the foot (some of which are attached beneath the arches and run from the front to the back of the foot). These muscles and ligaments, like the other supporting tissues of the body, are attached in two places. Many are attached at the heel bone. The body reacts to the stress at the heel bone by calcifying the soft tissue attachments and creating a spur.
Heel spurs are bony outgrowths positioned where the plantar fascia tissue attaches to the heel bone (the calcaneus). Heel spurs seldom cause pain. It is the inflamed tissue surrounding the spur that causes the pain. The Latin meaning of Plantar Fasciitis is, ?Inflammation of Plantar Fascia.? The plantar fascia is a long, thick and very tough band of tissue beneath your foot that provides arch support. It also connects your toes to your heel bone. Each time you take a step, the arch slightly flattens to absorb impact. This band of tissue is normally quite strong and flexible but unfortunately, circumstances such as undue stress, being overweight, getting older or having irregularities in your foot dynamics can lead to unnatural stretching and micro-tearing of the plantar fascia. This causes pain and swelling at the location where the plantar fascia attaches to the heel bone. As the fascia continually pulls at the heel bone, the constant irritation eventually creates a bony growth on the heel. This is called a heel spur.
Most of the time heel spurs present as pain in the region surrounding the spur, which typically increases in intensity after prolonged periods of rest. Patients may not be able to bear weight on the afflicted heel comfortably. Running, walking, or lifting heavy weight may exacerbate the issue.
A thorough history and physical exam is always necessary for the proper diagnosis of heel spurs and other foot conditions. X rays of the heel area are helpful, as excess bone production will be visible.
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.
When chronic heel pain fails to respond to conservative treatment, surgical treatment may be necessary. Heel surgery can provide pain relief and restore mobility. The type of procedure used is based on examination and usually consists of releasing the excessive tightness of the plantar fascia, called a plantar fascia release. The procedure may also include removal of heel spurs.
