Heel spurs are usually under the heel and are generally caused by excessive forces acting on the bone. By far the most common cause of heel spurs is abnormal biomechanics – often the same biomechanics that cause plantar fasciitis. Heel spurs are not a direct cause of heel pain. They grow in response to the forces of the soft tissue pulling on the bone. Any condition where the foot has excessive motion can produce tension within the soft tissues acting on the heel.
A heel spur can develop when there is an abundance of calcium creating a deposit in the calcaneus, or heel bone. Over time, this deposit grows to create an outcropping under the heel that extends into the foot. The result is a protrusion that leads to foot pain when pressure is applied, and in some cases, even during rest.
More often than not, heel spurs have no signs or symptoms, and you don?t feel any pain. This is because heel spurs aren?t pointy or sharp pieces of bone, contrary to common belief. Heel spurs don?t cut tissue every time movement occurs; they?re actually deposits of calcium on bone set in place by the body?s normal bone-forming mechanisms. This means they?re smooth and flat, just like all other bones. Because there?s already tissue present at the site of a heel spur, sometimes that area and the surrounding tissue get inflamed, leading to a number of symptoms, such as chronic heel pain that occurs when jogging or walking.
Diagnosis is made using a few different technologies. X-rays are often used first to ensure there is no fracture or tumor in the region. Then ultrasound is used to check the fascia itself to make sure there is no tear and check the level of scar tissue and damage. Neurosensory testing, a non-painful nerve test, can be used to make sure there is not a local nerve problem if the pain is thought to be nerve related. It is important to remember that one can have a very large heel spur and no plantar fasciitis issues or pain at all, or one can have a great deal of pain and virtually no spur at all.
Non Surgical Treatment
Initially, treatment usually consists of a combination of ice therapy, stretching exercises to improve flexibility (especially in the mornings), anti-inflammatory medications, and physical therapy. Most patients will also need custom-molded orthotics to help control the motion in the foot and arch, which takes the strain off the plantar fascia. If the pain continues, a cortisone injection may be used to calm the severe swelling and pain. There may the need for a night splint to maintain a stretch in the plantar fascia throughout the night.
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.
If you have not yet developed this condition, you can take steps to protect yourself from it. Most importantly, make it a rule to wear properly fitted footwear. Avoid shoes that have become worn down in the heel, and don’t choose shoes that cause you to walk in an abnormal fashion. Maintaining a healthy weight will ensure that undue pressure isn’t being put on the ligaments, tendons and bones of your feet. If your job requires a great deal of time on your feet, or if you exercise regularly, be sure to balance periods of activity with periods of rest for your feet.
