What May Cause Posterior Calcaneal Spur

Overview

The two most common causes of pain in the bottom of the heel, the arch, or both the heel and the arch, are heel spurs and plantar fasciitis. A Heel Spur is a piece of calcium or bone that sticks out from the bottom of the heel bone, and lies within the fibers of the plantar fascia. When walking, the spur digs into the plantar fascia and causes small micro-tears in the plantar fascia. This produces inflammation and pain in the heel, which at times may radiate into the arch.

Causes

Over-pronation (flat feet) is a common cause of heel spurs, but people with unusually high arches (pes cavus) can also develop heel spurs. Women have a significantly higher incidence of heel spurs due to the types of footwear often worn on a regular basis.



Symptoms

Pain and discomfort associated with heel spurs does not occur from the spur itself. The bone growth itself has no feeling. However, as you move, this growth digs into sensitive nerves and tissue along the heel of the foot, resulting in severe pain. Pain can also be generated when pushing off with the toes while walking. Swelling along the heel is also common.

Diagnosis

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

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.

Surgical Treatment

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.
