Approximately 10 per cent of the population may have heel spurs without any heel pain. Whilst recent research has raised the question of whether or not heel spurs are the result of the body trying to increase its base of support, heel spurs are still considered to be the result from strain on the muscles of the foot (in particular the plantar fascia). This may result from a biomechanical imbalance, such as over pronation.
This condition is a constellation of many causes; overweight, ill fitting shoes, bio-mechanical problems (mal-alignment of the heel), gout, pronation (a complex motion including outward rotation of the heel and inward rotation of the ankle) and rheumatoid arthritis are some of the causes of heel pain.
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 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
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.
