While the term heel spur may create the impression of a sharp bony projection on the bottom of the heel that pokes the bottom of our foot causing our pain. Painful heel spurs are actually a result of damage to the soft tissue at the bottom of the foot. While this may be confusing, we'll try to explain. Heel spurs is the more common name for a condition that is medically referred to as plantar fascitiis or heel spur syndrome. Plantar fasciitis is a location oriented term that refers to the bottom of the foot(i.e. plantar warts). Fascia is a tough, inelastic band. 'itis'is a term used to describe something that is inflamed (i.e. tendonitis, bursitis).
One frequent cause of injury to the plantar fascia is pronation. Pronation is defined as the inward and downward action of the foot that occurs while walking, so that the foot's arch flattens toward the ground (fallen arch). A condition known as excessive pronation creates a mechanical problem in the foot, and the portion of the plantar fascia attached to the heel bone can stretch and pull away from the bone. This damage can occur especially while walking and during athletic activities.
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.
Heel spurs and plantar fasciitis is usually diagnosed by your physiotherapist or sports doctor based on your symptoms, history and clinical examination. After confirming your heel spur or plantar fasciitis they will investigate WHY you are likely to be predisposed to heel spurs and develop a treatment plan to decrease your chance of future bouts. X-rays will show calcification or bone within the plantar fascia or at its insertion into the calcaneus. This is known as a calcaneal or heel spur. Ultrasound scans and MRI are used to identify any plantar fasciitis tears, inflammation or calcification. Pathology tests may identify spondyloarthritis, which can cause symptoms similar to plantar fasciitis.
Non Surgical Treatment
There are various ways to treat heel spurs. The first is to rest and apply ice to the afflicted area. Shoe inserts and night splints can also treat plantar fasciitis, and in turn, heels spurs. Unless you have stomach sensitivities, you may want to consider taking over-the-counter anti-inflammatory medication such as naprosyn to lower the swelling. A physical therapist can recommend gentle exercises and stretches to relax the tissue around the heel bone to relieve the tension. Even with these treatments, a stubborn heel spur may not go away. A physical therapist may decide to inject cortisone into the area to decrease inflammation, but that can cause other problems such as plantar fascial rupture and fat pad atrophy. Extracorporeal shock wave therapy is also an option, which uses energy pulses to apply microtrauma around the heel spur. Surgery is also an option but is not suggested unless the heel spur lasts more than a year. To prevent heel spurs from returning, shoe inserts can relieve the pressure on the plantar fascia. Also continue the recommended stretches and exercises.
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.
