Myth-conceptions about heel pain

Pain under the heel is one of the most common but least understood conditions affecting the foot. A recent review of the research literature demonstrates there is much misinformation regarding this condition.

Inflammation of the plantar fascia

Inflammation of the plantar fascia

Myth 1

Heel pain is due to inflammation of the plantar fascia

The plantar fascia is a dense band of tissue spanning from undersurface of the heel to the toes. Plantar fasciitis meaning inflammation of the plantar fascia, is the term most commonly used in the diagnosis of heel pain. A recent histological study of specimens taken from 50 surgical cases found marked thickening and fibrosis of the tissues with no evidence of inflammation. (Lemont, 2003) These findings are supported by others (Schepsis , 1991 and Tountas and Fonasier, 1996). The studies suggest that “plantar fasciitis” is better described as a degenerative fasciosis without inflammation, not a true fasciitis.

The absence of inflammation questions our long held assumptions and approaches to the management of heel pain using anti-inflammatory medication. The gastrointestinal and cardiovascular side effects of anti-inflammatory medication and the increased risk of rupture of the plantar fascia following cortisone injection should also be seriously considered. (Acevedo and Beskin, 1998; Sellman,1994)

Heel spur on x-ray

Myth 2

Heel spurs cause heel pain

Many patients and practitioners continue in the belief that the heel spur is the source of the patient’s symptoms despite evidence to the contrary. But heel spurs seen on X-ray are considered an insignificant finding.

Lapidus and Guidotti (1965) studied 134 patients with heel pain affecting one foot only and found that: 43% had spurs on both sides, 39% had no spurs, 14% had spurs on symptomatic side only and 3% had spurs on opposite side only. Spurs have also been shown to be a normal anatomical variant with only 3% located within the plantar fascia. (Abreu, 2003). If spurs are shown on X-ray, they will have been present long before and long after the presentation of heel pain.

Flat feet

Myth 3

People with flat feet are prone to heel pain

There are very few good studies exploring this relationship. Three studies demonstrated no association between arch height, the degree of pronation (rolling in of the foot) and heel pain. (Warren and Jones, 1987; Warren 1984; Powell, 1998). The only biomechanical factor shown to be associated with heel pain to date is a loss of ankle dorsiflexion (forward bending). (Kibler, 1991; Di Giovanni, 2003). Improvement in ankle dorsiflexion has been shown to correlate with reduction in heel pain. These findings support the rationale for calf stretching as an important part of treating heel pain.(Porter et al 2002)

Custom-made orthotics

Myth 4

Custom-made orthotics are the treatment of choice for heel pain

Studies investigating the effectiveness of custom-made foot orthotics (shoe inserts) have shown that they are no more effective than other less expensive approaches including off-the-shelf arch supports, night splints and silicone heel inserts. (Lynch, 1998; Martin, 2001; Pfeffer, 1999). These studies suggest that cushioned off-the-shelf devices appear to be as or more effective, than custom made devices, are considerably cheaper.
