Incidence of calcaneal spurs in osteo-arthrosis and rheumatoid arthritis, and in control patients.

Abstract

Calcaneal spurs were found in 81% of 168 patients with osteo-arthrosis compared with 21.6% of rheumatoid arthritics and 16.1% of controls. No sex difference was found in the incidence of calcaneal spurs. The frequency of calcaneal spurs increased with age. Inferior spurs are more common than posterior spurs but they are usually bilateral and symmetrical, whether the spurs are inferior or posterior.
