A heel spur is a hook of bone that can form on the heel bone of the foot. Heel spurs are associated with plantar fasciitis. Heel spurs can cause extreme pain in the rearfoot. The pain is most intense while standing or walking. What Causes Heel Spurs? Heel spurs develop as an abnormal growth in the heel bone due to calcium deposits that form when the plantar fascia stretches and pulls away from the heel. The plantar fascia is a ligament located at the bottom of your foot. This stretching of the plantar fascia is usually the result of flat feet or unusually high arches.
Bone spurs can form anywhere in the feet in response to tight ligaments, repetitive stress injuries (typically from sports), obesity, even poorly fitting shoes. For instance, when the plantar fascia on the bottom of the foot pulls repeatedly on the heel, the ligament becomes inflamed, causing plantar fasciitis. As the bone tries to mend itself, a bone spur forms on the bottom of the heel, typically referred to as a heel spur. This is a common source of heel pain.
Bone spurs may cause sudden, severe pain when putting weight on the affected foot. Individuals may try to walk on their toes or ball of the foot to avoid painful pressure on the heel spur. This compensation during walking or running can cause additional problems in the ankle, knee, hip, or back.
Your doctor will review your medical history and examine your foot. X-rays are used to identify the location and size of the heel spur.
Non Surgical Treatment
Many treatment options exist, and good results are often observed. Generally, a calcaneal spur develops when proper care is not given to the foot and heels. It is often seen as a repetitive stress injury, and thus lifestyle modification is typically the basic course of management strategies. To alleviate heel spur pain, a person should begin doing foot and calf workouts. Strong muscles in the calves and lower legs will help take the stress off the bone and thus help cure or prevent heel spurs. Icing the area is an effective way to get immediate pain relief.
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.
In 2002, researchers attempted to compare the effects of various running techniques on pronation and resulting injuries like stress fractures and heel spurs. They suggested that it is possible to teach runners to stride in such a way as to minimize impact forces. One way is to lower running speed. Another is to take longer rest periods following a run.
