Heel spurs occur in at least half the people who have plantar fasciitis, a painful condition involving the thick tissue that runs between your heel bone and your toes. In the past, doctors often performed surgery to remove heel spurs, believing them to be the cause of the pain associated with plantar fasciitis. In treating plantar fasciitis now, doctors rely more on ice, arch supports, physical therapy and pain medications, and surgery is rarely performed.
One frequent cause of heel spurs is an abnormal motion and mal-alignment of the foot called pronation. For the foot to function properly, a certain degree of pronation is required. This motion is defined as an inward action of the foot, with dropping of the inside arch as one plants the heel and advances the weight distribution to the toes during walking. When foot pronation becomes extreme from the foot turning in and dropping beyond the normal limit, a condition known as excessive pronation creates a mechanical problem in the foot. In some cases the sole or bottom of the foot flattens and becomes unstable because of this excess pronation, especially during critical times of walking and athletic activities. The portion of the plantar fascia attached into the heel bone or calcaneous begins to stretch and pull away from the heel bone.
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.
Because the diagnosis of heel spurs can be confused with tarsal tunnel syndrome (as described earlier), most surgeons advocate performing a tarsal tunnel release (or at least a partial tarsal tunnel release) along with the plantar fascia release. This surgery is about 80percent successful in relieving pain in the small group of patients who do not improve with conservative treatments.
Non Surgical Treatment
FIRST, Reduce the acute pain. This is done by a combination of several things; injection of a synthetic relative of cortisone into the heel, a prescription of anti-inflammatory pills to reduce inflammation, physical therapy and a special heel pad. About 50% of the time, these treatments will permanently relieve the pain. In the other 50%, the pain becomes recurrent, and the treatment proceeds to Stage II. SECOND, Recurrent, painful heel spur is caused by the tug and pull of the plantar fascia ligament on the heel bone with each step. When the pain is recurrent, arch supports are made to prevent sagging of the arch. The arch supports are custom-made according to the size and shape of the feet. This prevents the arch from sagging and the ligament from tugging and pulling on the heel bone. The inflammation and pain eventually go away as the first phase of treatment is continued along with the arch supports, although the spur itself remains. THIRD, Surgery to remove the spur is possible and is usually done as Day Surgery.
Heel spur surgery should only be considered after less invasive treatment methods have been explored and ruled insufficient. The traditional surgical approach to treating heel spurs requires a scalpel cut to the bottom of the food which allows the surgeon to access the bone spur. Endoscopic plantar fasciotomies (EPF) involve one or two small incisions in the foot which allow the surgeon to access and operate on the bone spur endoscopically. Taking a surgical approach to heel spur treatment is a topic to explore with a foot and ankle specialist.
