Overview
A heel spur is an abnormal growth of the heel bone, the largest bone in the foot which absorbs the greatest amount of shock and pressure. Calcium deposits form when the plantar fascia pulls away from the heel area, causing a bony protrusion, or heel spur to develop. 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.
Causes
A strong band of sinew (plantar fascia) stretches across the sole of the foot below the surface of the skin and is attached to a point in the middle of the under surface of the heel bone. With repeated activity on our feet, the plantar fascia can become tight and cause persistent traction (tugging) on its attachment point into the heel bone, and inflammation and pain may develop at this site. This painful condition is known as plantar fasciitis. Sometimes a ?spur? develops at the site of this traction on the bone and protrudes into the surrounding tissue. This is a heel spur.
Symptoms
Most of the time heel spurs present as pain in the region surrounding the spur, which typically increases in intensity after prolonged periods of rest. Patients may not be able to bear weight on the afflicted heel comfortably. Running, walking, or lifting heavy weight may exacerbate the issue.
Diagnosis
Heel spurs and plantar fasciitis is usually diagnosed by your physiotherapist or sports doctor based on your symptoms, history and clinical examination. After confirming your heel spur or plantar fasciitis they will investigate WHY you are likely to be predisposed to heel spurs and develop a treatment plan to decrease your chance of future bouts. X-rays will show calcification or bone within the plantar fascia or at its insertion into the calcaneus. This is known as a calcaneal or heel spur. Ultrasound scans and MRI are used to identify any plantar fasciitis tears, inflammation or calcification. Pathology tests may identify spondyloarthritis, which can cause symptoms similar to plantar fasciitis.
Non Surgical Treatment
Get some rest. You need to stay off of your aching foot as much as possible for at least a week. Think about possible causes of the problem while you're resting and figure out how you can make some changes. Some actions that can contribute to heel spurs include running too often or running on hard surfaces such as concrete, tight calf muscles, shoes with poor shock absorption. Ease back into your activities. In many cases, you'll be in too much pain to go ahead with a strenuous exercise routine that puts pressure or impact on your heel. Listen to your body and switch to different activities such as swimming or riding a bike until your heel spurs improve.
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.
Prevention
You can prevent heel spurs by wearing well-fitting shoes with shock-absorbent soles, rigid shanks, and supportive heel counters; choosing appropriate shoes for each physical activity; warming up and doing stretching exercises before each activity; and pacing yourself during the activities. Avoid wearing shoes with excessive wear on the heels and soles. If you are overweight, losing weight may also help prevent heel spurs.
