A heel spur is a painful condition that is caused by the accumulation of excessive calcium under the heel of the foot. The heel bone is made up of a large structure called the calcaneus, which is connected to the bottom of the foot by durable connective tissue called fascia. If the layers of connective tissue become damaged or begin to degenerate due to wear and tear, plantar fasciitis may develop. This causes calcification, which refers to the abnormal buildup of calcium on the heel bone. As the calcium continues to accumulate, a calcified protrusion called a spur may become visible on an X-ray.
Diseases such as arthritis may lead to chronic inflammation in the tissue surrounding the heel and over time this can lead to the accumulation of calcium deposits. Ankylosing spondylitis, for example, is one particular form of arthritis that frequently develops along with heel spurs. This condition can damage bones all over the body and even lead to the fusion of spinal vertebrae.
Heel spurs can be quite painful, but can just as likely occur with no symptoms at all. Plantar fasciitis is a contributing condition to heel spurs. The cause of the pain is not the heel spur itself but the soft-tissue injury associated with it. The feeling has been described as a knife or pin sticking into the bottom of your feet when you first stand up after sitting or laying down for a long period of time - a pain that later turns into a dull ache.
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. The plantar fascia is the thick, connective tissue that runs from the calcaneus (heel bone) to the ball of the foot. This strong and tight tissue helps maintain the arch of the foot. It is also one of the major transmitters of weight across the foot as you walk or run. In other words, tremendous stress is placed on the plantar fascia.
Non Surgical Treatment
Some heel spurs do require surgery, however surgery is a last resort. In most cases the patients underlying foot problem needs to be addressed, such as Over Pronation and Over Supination and Heel Pain Treatment Options need to be implemented if Plantar Fasciitis and Achilles Tendonitis are still an ongoing concern. Your best treatment is always prevention.
Surgery involves releasing a part of the plantar fascia from its insertion in the heel bone, as well as removing the spur. Many times during the procedure, pinched nerves (neuromas), adding to the pain, are found and removed. Often, an inflamed sac of fluid call an accessory or adventitious bursa is found under the heel spur, and it is removed as well. Postoperative recovery is usually a slipper cast and minimal weight bearing for a period of 3-4 weeks. On some occasions, a removable short-leg walking boot is used or a below knee cast applied.
Heel spurs and plantar fasciitis can only be prevented by treating any underlying associated inflammatory disease.
