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.
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.
Some symptoms at the beginning of this condition include pain and swelling, and discomfort when pushing off with the toes during walking. This movement of the foot stretches the fascia that is already irritated and inflamed. If this condition is not treated, pain will be noticed in the heel when a heel spur develops in response to the stress. This is a common condition among athletes and others who run and jump a significant amount.
Most patients who are suffering with heel spurs can see them with an X-ray scan. They are normally hooked and extend into the heel. Some people who have heel spur may not even have noticeable symptoms, although could still be able to see a spur in an X-ray scan.
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.
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.
