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.
A heel spur usually develops as a result of wear and tear over time, which leads to the degeneration of connective tissue called fascia. Standing for prolonged periods and wearing shoes that do not provide the right type of arch support can also lead to connective tissue damage in the heel. The body attempts to repair the damaged tissue by delivering calcium to the affected region, but sometimes too much calcium begins to accumulate and this results in painful plantar fasciitis.
The pain caused by a calcaneal spur is not the result of the pressure of weight on the point of the spur, but results from inflammation around the tendons where they attach to the heel bone. You might expect the pain to increase as you walk on the spur, but actually it decreases. The pain is most severe when you start to walk after a rest. The nerves and capillaries adapt themselves to the situation as you walk. When you rest, the nerves and capillaries rest, also. Then, as you begin to move about again, extreme demands are made on the blood vessels and nerves, which will cause pain until they again adjust to the spur. If excessive strain has been placed on the foot the day before, the pain may also be greater. A sudden strain, as might be produced by leaping or jumping, can also increase the pain. The pain might be localized at first, but continued walking and standing will soon cause the entire heel to become tender and painful.
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.
Almost 90% of the people suffering from heel spur get better with nonsurgical treatments. However, if the conservative treatments do not help you and you still have pain even after 9 to 12 months, your doctor may advise surgery for treating heel spur. The surgery helps in reducing the pain and improving your mobility. Some of the surgical techniques used by doctors are release of the plantar fascia. Removal of a spur. Before the surgery, the doctor will go for some pre-surgical tests and exams. After the operation, you will need to follow some specific recommendations which may include elevation of the foot, waiting time only after which you can put weight on the foot etc.
