The heel spur (or calcaneal spur) is a nail-like growth of calcium around the ligaments and tendons of the foot where they attach to the heel bone. The spur grows from the bone and into the flesh of the foot. A heel spur results from an anatomical change of the calcaneus (heel bone). This involves the area of the heel and occasionally, another disability, such as arthritis. The heel bone forms one end of the two longitudinal arches of the foot. These arches are held together by ligaments and are activated by the muscles of the foot (some of which are attached beneath the arches and run from the front to the back of the foot). These muscles and ligaments, like the other supporting tissues of the body, are attached in two places. Many are attached at the heel bone. The body reacts to the stress at the heel bone by calcifying the soft tissue attachments and creating a spur.
A major cause of heel spur pain comes from the development of new fibrous tissue around the bony spur, which acts as a cushion over the area of stress. As this tissue grows, a callus forms and takes up even more space than the heel spur, leading to less space for the thick surrounding network of tendons, nerves, ligaments and supporting tissue. These important structures in the foot have limited space because of calcium or tissue buildup, which leads to swelling and redness of the foot, and a deep throbbing pain worsened with exercise.
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.
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
Common and effective treatments for Heel Spurs include: Stretching exercises, changing to specific shoes, taping or strapping to rest stressed muscles and tendons, custom orthotic devices and physiotherapy. There are many things you can do to treat heel spurs. You should stretch the muscles and ligaments around the area regularly and ensure you are wearing the right footwear for your feet. There are also tapes and straps that you can apply to the muscles and tendons around the area. For more severe cases, custom orthotics may be the way to go along with aggressive physiotherapy. To treat the pain, over the counter NSAIDs (anti-inflammatory medications) is recommended, but use with caution as prolonged use can lead to the development of ulcers. It is therefore best to apply a topical treatment such as Zax?s Original Heelspur Cream, which contains natural ingredients proven to reduce pain and inflammation. More severe forms of the condition may require corticosteroid injections or surgical procedures, but these are very rare cases. Still, should pain become worse and persist, you should consult with your doctor.
Usually, heel spurs are curable with conservative treatment. If not, heel spurs are curable with surgery, although there is the possibility of them growing back. About 10% of those who continue to see a physician for plantar fascitis have it for more than a year. If there is limited success after approximately one year of conservative treatment, patients are often advised to have surgery.
