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 can form as a result of repeated strain placed on foot muscles and ligaments as well as from abnormally stretching the band of tissue connecting the heel and ball of the foot. Repeated injury to the membrane that lines the heel bone can also cause problems as can repeated tight pressure on the back of the heel. The causes can range from excessive walking (especially if unaccustomed to walking), running or jumping to improperly fitted or worn-out shoes. Runners, volleyball players, and tennis players, people who do step aerobics or stair climbing for exercise, those with flat feet, pregnant women, the obese and diabetics and those who wear tight-fitting shoes with a high heel are all prone to developing spurs (and plantar fasciitis) more readily.
Heel spurs result in a jabbing or aching sensation on or under the heel bone. The pain is often worst when you first arise in the morning and get to your feet. You may also experience pain when standing up after prolonged periods of sitting, such as work sessions at a desk or car rides. The discomfort may lessen after you spend several minutes walking, only to return later. Heel spurs can cause intermittent or chronic pain.
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
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.
Have surgery if no other treatments work. Before performing surgery, doctors usually give home treatments and improved footwear about a year to work. When nothing else eases the pain, here's what you need to know about surgical options. Instep plantar fasciotomy. Doctors remove part of the plantar fascia to ease pressure on the nerves in your foot. Endoscopy. This surgery performs the same function as an instep plantar fasciotomy but uses smaller incisions so that you'll heal faster. However, endoscopy has a higher rate of nerve damage, so consider this before you opt for this option. Be prepared to wear a below-the-knee walking cast to ease the pain of surgery and to speed the healing process. These casts, or "boots," usually work better than crutches to speed up your recovery time.
If you have not yet developed this condition, you can take steps to protect yourself from it. Most importantly, make it a rule to wear properly fitted footwear. Avoid shoes that have become worn down in the heel, and don't choose shoes that cause you to walk in an abnormal fashion. Maintaining a healthy weight will ensure that undue pressure isn't being put on the ligaments, tendons and bones of your feet. If your job requires a great deal of time on your feet, or if you exercise regularly, be sure to balance periods of activity with periods of rest for your feet.
