What Is Calcaneal Spur

Overview

Heel spurs are tiny protruding calcium deposits that can develop near the base of your heel bone. They can be caused by repetitive activities, such as dancing or running, or they can form in association with plantar fasciitis, which is an inflammation of the ligament (plantar fascia) on the bottom of your foot. When the plantar fascia is tight and pulls on your heel bone, the bone releases calcium to try to heal itself. The excess deposits of calcium can sometimes form heel spurs.

Causes

An individual with the lower legs angulating inward, a condition called genu valgum or "knock knees," can have a tendency toward excessive pronation. As a result, this too can lead to a fallen arch resulting in plantar fascitis and heel spurs. Women tend to have more genu valgum than men do. Heel spurs can also result from an abnormally high arch. Other factors leading to heel spurs include a sudden increase in daily activities, an increase in weight, or a change of shoes. Dramatic increase in training intensity or duration may cause plantar fascitis. Shoes that are too flexible in the middle of the arch or shoes that bend before the toe joints will cause an increase in tension in the plantar fascia and possibly lead to heel spurs.



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

The diagnosis of heel pain and heel spurs is made by a through history of the course of the condition and by physical exam. Weight bearing x-rays are useful in determining if a heel spur is present and to rule out rare causes of heel pain such as a stress fracture of the heel bone, the presence of bone tumors or evidence of soft tissue damage caused by certain connective tissue disorders.

Non Surgical Treatment

Perform some exercises. Exercises that strengthen and lengthen your plantar fascia can also be very helpful for heel spurs. Try some of the following activities. Calf stretch. Place your hands on a wall. Extend 1 foot (0.3 m) behind you with your knee straight and place the other foot in front of you with the knee bent. Push your hips toward the wall and hold the stretch for 10 seconds. You should feel a pull in your calf muscles. Repeat the stretch 20 times for each foot. Plantar fascia stretch, Perform this exercise in the morning before you've done any standing or walking. Cross your injured foot over the knee of your other leg. Grasp your toes and gently pull them toward you. If you can't reach your toes, then wrap a towel around them and pull on the towel. Hold the stretch for 10 seconds and repeat 20 times for each foot.

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.

Prevention

Walk around before you buy shoes. Before you purchase your shoes, do the following. Re-lace the shoes if you're trying on athletic shoes. Start at the farthest eyelets and apply even pressure to the laces as you come closer to the tongue of the shoe. Make sure that you can wiggle your toes freely inside of the shoe. Also, make sure that you have at enough space between your tallest toe and the end of the shoe. You should have room equal to about the width of your thumb in the tip of your shoe. Walk around to make sure that the shoe has a firm grip on your heel without sliding up and down. Walk or run a few steps to make sure your shoes are comfortable. Shoes that fit properly require no break-in period.
