Overview
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.
Causes
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.
Symptoms
If your body has created calcium build-ups in an effort to support your plantar fascia ligament, each time you step down with your foot, the heel spur is being driven into the soft, fatty tissue which lines the bottom of your heel. Heel spur sufferers experience stabbing sensations because the hard protrusion is literally being jabbed into the heel pad. If left untreated, Plantar Fasciitis and heel spurs can erode the fatty pad of the heel and cause permanent damage to the foot. Fortunately, most cases can be resolved without medications or surgeries.
Diagnosis
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
Heel spurs are considered a self-limited condition, which means that by making small alterations in your lifestyle and regular routines you can often control the condition. The goal is to relieve pain, reduce friction and transfer pressure from your sensitive foot areas. By eliminating the cause of the heel spur and plantar fasciitis (i.e. better shoes, orthotics to fix your gait, losing weight) will help reduce the pressure put on your fascia and heel and can reduce the inflammation caused by your heel spur. Failure to see improvements after conservative treatments may make surgery your only option.
Surgical Treatment
Approximately 2% of people with painful heel spurs need surgery, meaning that 98 out of 100 people do well with the non-surgical treatments previously described. However, these treatments can sometimes be rather long and drawn out, and may become considerably expensive. Surgery should be considered when conservative treatment is unable to control and prevent the pain. If the pain goes away for a while, and continues to come back off and on, despite conservative treatments, surgery should be considered. If the pain really never goes away, but reaches a plateau, beyond which it does not improve despite conservative treatments, surgery should be considered. If the pain requires three or more injections of "cortisone" into the heel within a twelve month period, surgery should be considered.
