A heel spur is caused by the displacement of calcium on the bone that forms on the underside of the heel, it may be one small bony protrusion or a collection of tiny, irregularly shaped growths on the bone of the heel, which is called the calcaneum. Heel spurs are sometimes painful, described as a knife digging into the heel and other times, a heel spur goes unnoticed and is only detected by an X-ray.
Heel spurs develop as an abnormal growth in the heel bone due to calcium deposits that form when the plantar fascia pulls away from the heel. This stretching of the plantar fascia is usually the result of over-pronation (flat feet), but people with unusually high arches (pes cavus) can also develop heel spurs. Women have a significantly higher incidence of heel spurs due to the types of footwear often worn on a regular basis.
The following symptoms are typical of heel spur. Stabbing pain when treading on the area affected. Dull, irregularly occurring pains in the heel area also without exerting pressure (e.g. in a reclining position) Pain when taking the first steps in the morning (after lying or sitting down for an extended period, especially in the morning) Occasional swelling in the ankle area. For the lower heel spur, extreme sensitivity at the tendon attachment (laterally in the lower heel area) For the upper heel spur, extreme pressure sensitivity of the Achilles tendon, primarily at approximately ankle height.
A heel spur is often seen on X-ray as a bony protrusion, which can vary in size. However, because a Heel Spur only indicates increased load on the plantar fascia, and not pain, an ultra sound may be required to assess other actual cause of the heel pain such and may include checking to see if the plantar fascia is inflamed or degenerated.
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.
When chronic heel pain fails to respond to conservative treatment, surgical treatment may be necessary. Heel surgery can provide pain relief and restore mobility. The type of procedure used is based on examination and usually consists of releasing the excessive tightness of the plantar fascia, called a plantar fascia release. The procedure may also include removal of heel spurs.
