What Can Cause Calcaneal Spur

Inferior Calcaneal Spur

Overview

Heel spurs (calcaneal spurs) are protrusions (bumps) on the forward underside of the heel bone that can occur when the plantar tendon pulls excessively in the area where it attaches to the bone. The condition is often associated with plantar fasciitis, although it can also occur on its own. Heel spurs typically are not painful unless they intrude into the soft tissue (plantar fascia), where they can cause irritation that results in heel pain.

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.

Heel Spur

Symptoms

Heel spurs can be quite painful, but can just as likely occur with no symptoms at all. Plantar fasciitis is a contributing condition to heel spurs. The cause of the pain is not the heel spur itself but the soft-tissue injury associated with it. The feeling has been described as a knife or pin sticking into the bottom of your feet when you first stand up after sitting or laying down for a long period of time - a pain that later turns into a dull ache.

Diagnosis

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. The plantar fascia is the thick, connective tissue that runs from the calcaneus (heel bone) to the ball of the foot. This strong and tight tissue helps maintain the arch of the foot. It is also one of the major transmitters of weight across the foot as you walk or run. In other words, tremendous stress is placed on the plantar fascia.

Non Surgical Treatment

Treatment of Heel Spurs is the same as treatment of plantar fasciitis. To arrive at an accurate diagnosis, our foot and ankle Chartered Physiotherapists will obtain your medical history and examine your foot. Throughout this process the physio will rule out all the possible causes for your heel pain other than plantar fasciitis. The following treatment may be used. Orthotics/Insoles. Inflammation reduction. Mobilisation. Taping and Strapping. Rest.

Surgical Treatment

Surgery is used a very small percentage of the time. It is usually considered after trying non-surgical treatments for at least a year. Plantar fascia release surgery is use to relax the plantar fascia. This surgery is commonly paired with tarsal tunnel release surgery. Surgery is successful for the majority of people.

Prevention

Prevention of heel spur syndrome may be best by finding a good supportive shoe. Never go barefoot or wear a flat soled shoe. There are many over the counter arch supports that give increased support for your feet. Usually when there is excessive pronation the Achilles Tendon contracts or becomes shortened over time since it is not being used fully. The shortened Achilles Tendon is called an equinus deformity. By keeping this tendon stretched it may decrease some of the tension in the foot. Some theories believe the Achilles Tendon and plantar fascia is continuous. Before you get up from rest, stretch out your Achilles and the plantar fascia. You may attempt to spell the alphabet with your foot and ankle, use a towel against pressure on your foot, or roll a can of soup or sodapop on the ground. Ice may work well at the times of severe pain. For a chronic pain, or longer lasting pain heat therapy may improve the condition.
