title: [Algodystrophy in children and young adults with low isotope retention in the bones. Apropos of 5 cases].
abstract: The authors report 5 observations of young adults, 3 teen-agers and 2 children suffering from algodystrophy, and in whom isotopic exploration of the skeleton disclosed a clear bony hypofixation during the entire evolution. These observations confirm their 1981 work concerning a young adult suffering from algodystrophy with isotopic bony hypofixation. Recent Canadian and American studies emphasize also the frequency of isotopic hypofixation in children algodystrophy. It seems, therefore, that isotopic bony hypofixation (linked perhaps to a decreased blood flow), is rather specific of algodystrophy in young subjects.
