A common cause of heel pain is the heel spur, which is a bony growth on the underside of the heel bone. The spur, visible by X-ray, appears as a protrusion that can extend forward as much as half an inch. When there is no indication of bone enlargement, the condition is sometimes referred to as ?heel spur syndrome.?
Heel spurs result from strain on the muscles and ligaments of the foot, by stretching of the long band of tissue that connects the heel and the ball of the foot, and by repeated tearing away of the lining or membrane that covers the heel bone. These conditions may result from biomechanical imbalance, running or jogging, improperly fitted or excessively worn shoes, or obesity. Heel spurs specifically relate to the bony spurs (extra bony growth) that form at the base of the heel. It is a ?spike? of bone that grows from the base of the heel.
A heel spur is caused by chronic plantar fasciitis. Your plantar fascia is a thick fibrous band of connective tissue originating on the bottom surface of the calcaneus (heel bone) and extending along the sole of the foot towards the toes.Your plantar fascia acts as a passive limitation to the over flattening of you arch. When your plantar fascia develops micro tears or becomes inflamed it is known as plantar fasciitis. When plantar fasciitis healing is delayed or injury persists, your body repairs the weak and injured soft tissue with bone. Usually your injured fascia will be healed via fibroblastic activity. They’ll operate for at least six weeks. If your injury persists beyond this time, osteoblasts are recruited to the area. Osteoblasts form bone and the end result is bone (or calcification) within the plantar fascia or at the calcaneal insertion. These bone formations are known as heel spurs. This scenario is most common in the traction type injury. The additional bone growth is known as a heel spur or calcaneal spur.
You’ll typically first notice early heel spur pain under your heel in the morning or after resting. Your heel pain will be worse with the first steps and improves with activity as it warms up. When you palpate the tender area you may feel a tender bony lump. As your plantar fasciitis deteriorates and your heel spur grows, the pain will be present more often.
Heel spurs and plantar fasciitis are diagnosed based on the history of pain and tenderness localized to these areas. They are specifically identified when there is point tenderness at the bottom of the heel, which makes it difficult to walk barefoot on tile or wood floors. X-ray examination of the foot is used to identify the bony prominence (spur) of the heel bone (calcaneus).
Non Surgical Treatment
Heel pain may be associated with a heel spur, however the heel pain is usually due to plantar fasciitis, rather than a heel spur, so treatment is usually directed at the plantar fasciitis itself. Treatment usually involves application of ice to reduce pain and inflammation, special stretching exercises, and pain-relieving or anti-inflammatory medicines. Night splints or orthotics may be recommended. It may help to avoid the activities that aggravate pain, such as long walks and running. Surgery is very rarely recommended and only after other measures fail.
Most studies indicate that 95% of those afflicted with heel spurs are able to relieve their heel pain with nonsurgical treatments. If you are one of the few people whose symptoms don?t improve with other treatments, your doctor may recommend plantar fascia release surgery. Plantar fascia release involves cutting part of the plantar fascia ligament in order to release the tension and relieve the inflammation of the ligament. Sometimes the bone spur is also removed, if there is a large spur (remember that the bone spur is rarely a cause of pain. Overall, the success rate of surgical release is 70 to 90 percent in patients with heel spurs. One should always be sure to understand all the risks associated with any surgery they are considering.
In 2002, researchers attempted to compare the effects of various running techniques on pronation and resulting injuries like stress fractures and heel spurs. They suggested that it is possible to teach runners to stride in such a way as to minimize impact forces. One way is to lower running speed. Another is to take longer rest periods following a run.
