A heel spur occurs when calcium deposits build up on the underside of the heel bone. The abnormal calcium deposits form when the plantar fascia pulls away from the heel. This stretching of the plantar fascia is common among people who have flat feet, but people with unusually high arches can also develop this problem. Heel spurs are especially common among athletes who do a lot of running and jumping. Also, women who wear high heels have a significantly higher incidence of heel spurs. Still, it can happen to anyone.
A heel spur can develop when there is an abundance of calcium creating a deposit in the calcaneus, or heel bone. Over time, this deposit grows to create an outcropping under the heel that extends into the foot. The result is a protrusion that leads to foot pain when pressure is applied, and in some cases, even during rest.
With heel spurs, people often talk about a dull ache which is felt most of the time with episodes of a sharp pain in the center of the heel or on the inside margin of the heel. Often the pain is worse on first rising in the morning and after rest and is aggravated by prolonged weight bearing and thin-soled shoes.
Your doctor will review your medical history and examine your foot. X-rays are used to identify the location and size of the heel spur.
Non Surgical Treatment
The key for the proper treatment of heel spurs is determining what is causing the excessive stretching of the plantar fascia. When the cause is over-pronation (flat feet), an orthotic with rearfoot posting and longitudinal arch support is an effective device to reduce the over-pronation, and allow the condition to heal. Other common treatments include stretching exercises, losing weight, wearing shoes that have a cushioned heel that absorbs shock, and elevating the heel with the use of a heel cradle, heel cup, or orthotic. Heel cradles and heel cups provide extra comfort and cushion to the heel, and reduce the amount of shock and shear forces experienced from everyday activities.
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.
Choose new shoes that are the right size. Have your foot measured when you go to the shoe store instead of taking a guess about the size. Also, try on shoes at the end of the day or after a workout, when your feet are at their largest. To ensure a good fit, wear the same type of socks or nylons that you would normally wear with the type of shoe that you are trying on.
