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 is a bony overgrowth on the bottom of your heel bone. The heel spur is usually a result of an inflamed ligament (plantar fascia) on the bottom of the foot that attaches to the heel bone. Constant abnormal pulling of this ligament irritates the heel bone and the body lays down a bone spur as a protective mechanism. The patient usually complains of pain with the first step in the morning, some relief following activity, but returning after extended amounts of time standing or walking.
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.
Diagnosis of a heel spur can be done with an x-ray, which will be able to reveal the bony spur. Normally, it occurs where the plantar fascia connects to the heel bone. When the plantar fascia ligament is pulled excessively it begins to pull away from the heel bone. When this excessive pulling occurs, it causes the body to respond by depositing calcium in the injured area, resulting in the formation of the bone spur. The Plantar fascia ligament is a fibrous band of connective tissue running between the heel bone and the ball of the foot. This structure maintains the arch of the foot and distributes weight along the foot as we walk. However, due to the stress that this ligament must endure, it can easily become damaged which commonly occurs along with heel spurs.
Non Surgical Treatment
There are many ways to treat heel spurs. Some remedies you can even do at home once a podiatrist shows you how. Heel spur treatment is very similar to treatment of plantar fasciitis. Here are a few of the most common treatments. First, your doctor will assess which activities are causing your symptoms and suggest rest and time off from these activities. Ice packs are used to control pain and reduce symptoms. Certain exercises and stretches help you to feel relief quickly. Medications that reduce inflammation and decrease pain are also used. Sometimes cortisone injections are given. Often special shoe orthotics can help to take the pressure off of the plantar fascia and reduce symptoms. Night splints that keep your heel stretched are sometimes recommended. Rarely, surgery is an option. A new treatment called extracorporeal shock wave therapy is being studied.
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.
