[The calcaneus in the Fiessinger-Leroy-Reiter syndrome].

The authors report on 43 cases of calcaneitis seen out of 121 cases of Fiessinger-Leroy-Reiter syndrome. They describe the three developmental stages and show that the polymorphism of the radiological aspects realized depend on the very great variability of the speed of development of the pathological process from one case to another. Calcaneitis of the Fiessinger-Leroy-Reiter syndrome always ends in cure.
