The heel bone is the largest bone in the foot and absorbs the most shock and pressure. A heel spur develops as an abnormal growth of the heel bone. Most commonly, calcium deposits form when the plantar fascia pulls away from the heel area, causing a bony protrusion, or heel spur to develop. While bone spurs can develop in other locations such as the rear of the heel bone, this is the most common location for development. The plantar fascia is a broad band of fibrous tissue located along the bottom surface of the foot that runs from the heel to the forefoot. Heel spurs can cause extreme pain in the rearfoot, especially while standing or walking.
When a patient has plantar fasciitis, the plantar fascia becomes inflamed and degenerative (worn out)--these abnormalities can make normal activities quite painful. Symptoms typically worsen early in the morning after sleep. At that time, the plantar fascia is tight so even simple movements stretch the contracted plantar fascia. As you begin to loosen the plantar fascia, the pain usually subsides, but often returns with prolonged standing or walking.
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.
Diagnosis is made using a few different technologies. X-rays are often used first to ensure there is no fracture or tumor in the region. Then ultrasound is used to check the fascia itself to make sure there is no tear and check the level of scar tissue and damage. Neurosensory testing, a non-painful nerve test, can be used to make sure there is not a local nerve problem if the pain is thought to be nerve related. It is important to remember that one can have a very large heel spur and no plantar fasciitis issues or pain at all, or one can have a great deal of pain and virtually no spur at all.
Non Surgical Treatment
Acupuncture and acupressure can used to address the pain of heel spurs, in addition to using friction massage to help break up scar tissue and delay the onset of bony formations. Physical therapy may help relieve pain and improve movement. The Feldenkrais method could be especially helpful for retraining some of the compensation movements caused by the pain from the spur. Guided imagery or a light massage on the foot may help to relieve some of the pain. Other treatments include low-gear cycling, and pool running. Some chiropractors approve of moderate use of aspirin or ibuprofen, or other appropriate anti-inflammatory drugs. Chiropractic manipulation is not recommended, although chiropractors may offer custom-fitted shoe orthotics and other allopathic-type treatments.
Surgery is used a very small percentage of the time. It is usually considered after trying non-surgical treatments for at least a year. Plantar fascia release surgery is use to relax the plantar fascia. This surgery is commonly paired with tarsal tunnel release surgery. Surgery is successful for the majority of people.
