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 are common in patients who have a history of foot pain caused by plantar fasciitis. In the setting of plantar fasciitis, heel spurs are most often seen in middle-aged men and women, but can be found in all age groups. The heel spur itself is not thought to be the primary cause of pain, rather inflammation and irritation of the plantar fascia is thought to be the primary problem. A heel spur diagnosis is made when an X-ray shows a hook of bone protruding from the bottom of the foot at the point where the plantar fascia is attached to the heel bone.
Heel spur is characterised by a sharp pain under the heel when getting out of bed in the morning or getting up after sitting for a period of time. Walking around for a while often helps reduce the pain, turning it into a dull ache. However, sports, running or walking long distance makes the condition worse. In some cases swelling around the heel maybe present.
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
Since heel spurs are not an indication of pain themselves unless fractured, treatment is usually aimed at the cause of the pain which in many cases is plantar fasciosis. Treatment of plantar fasciiosis includes; rest until the pain subsides, special stretching exercises and if required orthotics may be prescribed.
Have surgery if no other treatments work. Before performing surgery, doctors usually give home treatments and improved footwear about a year to work. When nothing else eases the pain, here's what you need to know about surgical options. Instep plantar fasciotomy. Doctors remove part of the plantar fascia to ease pressure on the nerves in your foot. Endoscopy. This surgery performs the same function as an instep plantar fasciotomy but uses smaller incisions so that you'll heal faster. However, endoscopy has a higher rate of nerve damage, so consider this before you opt for this option. Be prepared to wear a below-the-knee walking cast to ease the pain of surgery and to speed the healing process. These casts, or "boots," usually work better than crutches to speed up your recovery time.
Prevention of heel spur syndrome may be best by finding a good supportive shoe. Never go barefoot or wear a flat soled shoe. There are many over the counter arch supports that give increased support for your feet. Usually when there is excessive pronation the Achilles Tendon contracts or becomes shortened over time since it is not being used fully. The shortened Achilles Tendon is called an equinus deformity. By keeping this tendon stretched it may decrease some of the tension in the foot. Some theories believe the Achilles Tendon and plantar fascia is continuous. Before you get up from rest, stretch out your Achilles and the plantar fascia. You may attempt to spell the alphabet with your foot and ankle, use a towel against pressure on your foot, or roll a can of soup or sodapop on the ground. Ice may work well at the times of severe pain. For a chronic pain, or longer lasting pain heat therapy may improve the condition.
