Approximately 10 per cent of the population may have heel spurs without any heel pain. Whilst recent research has raised the question of whether or not heel spurs are the result of the body trying to increase its base of support, heel spurs are still considered to be the result from strain on the muscles of the foot (in particular the plantar fascia). This may result from a biomechanical imbalance, such as over pronation.
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.
Most heel spurs cause no symptoms and may go undetected for years. If they cause no pain or discomfort, they require no treatment. Occasionally, a bone spur will break off from the larger bone, becoming a ?loose body?, floating in a joint or embedding itself in the lining of the joint. This can cause pain and intermittent locking of the joint. In the case of heel spurs, sharp pain and discomfort is felt on the bottom of the foot or heel.
A Diagnosis of Heel Spur Syndrome is a very common reason for having heel pain. Heel pain may be due to other types of conditions such as tendonitis, Haglund's Deformity, Stress Fracture, Tarsal Tunnel Syndrome, or low back problems. A more common condition in children is Sever's Disease. The diagnosis is usually made with a combination of x-ray examination and symptoms.
Non Surgical Treatment
Bone spurs rarely require treatment unless they are causing frequent pain or damaging other tissues. Because heel spurs and plantar fasciitis are so closely related, they are usually treated the same way. Symptomatic treatment involves rest, especially from the activity that is contributing to the condition and making symptoms worse (although this may not be easy to discover, as problems can manifest several hours or days after the harmful activity has occurred). If you identify the offending activity, ice is recommended immediately following it. Stretching of the calf muscles after a short warm up is also a good idea and can be helpful. Stretching exercises that gently lengthen the calm muscle will relax the tissue surrounding the heel and should be done several times a day, especially in the morning and after prolonged sitting.
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.
