When the body is under stress or constent inflammation it will deposit calcium to our bones. This added ‘bone growth’ is designed to relieve the added stress/pressure to our connective tissue. In the case of a heel spur, added calcium to the heel bone (calcaneus). It usually forms at the bottom underside of the heel bone where the plantar fascia attaches. This calcium deposit forms over a period of many months. Heel bones can very in shape and size from person to person. An irregular shape heel (calcaneus) can cause the tissue to twist (plantar ligament and Achilles tendon) or a smaller heel bone will put additional stress on tendons and ligaments.
Heel spurs form in some patients who have plantar fasciitis (PLAN-tar fash-ee-I-tis), and tend to occur in patients who have had the problem for a prolonged period of time. While about 70 percent of patients with plantar fasciitis have a heel spur, X-rays also show about 50 percent of patients with no symptoms of plantar fasciitis also have a heel spur.
Although it may take years to become a problem, once it appears, it may cause considerable suffering. Because of proximity to the tendons, the spur is a source of continuous painful aching. The sensation has been described as “a toothache in the foot.” When you place your weight on the heel, the pain can be sufficient to immobilize you.
The proper diagnosis of a heel spur often requires an X-ray. To make this process as convenient for his patients as possible, most clinics have an on-site digital X-ray and diagnostic ultrasound machines. This can make it unnecessary for patients to visit diagnostic imaging centers, allowing patients to receive more expedient treatment.
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.
More than 90 percent of people get better with nonsurgical treatments. If conservative treatment fails to treat symptoms of heel spurs after a period of 9 to 12 months, surgery may be necessary to relieve pain and restore mobility. Surgical techniques include release of the plantar fascia, removal of a spur. Pre-surgical tests or exams are required to identify optimal candidates, and it’s important to observe post-surgical recommendations concerning rest, ice, compression, elevation of the foot, and when to place weight on the operated foot. In some cases, it may be necessary for patients to use bandages, splints, casts, surgical shoes, crutches, or canes after surgery. Possible complications of heel surgery include nerve pain, recurrent heel pain, permanent numbness of the area, infection, and scarring. In addition, with plantar fascia release, there is risk of instability, foot cramps, stress fracture, and tendinitis.
