[Infra-radiographic decalcifying algodystrophy of the lower limb].

The authors have only reported cases responding to the following criteria: A) necessarily: 1) Clinical appearance of algodystrophy. 2) Intense hyperfixation of the bone scan. 3) X rays repeated a sufficient number of times always normal and submitted to the judgement of six rheumatologists not forewarned, to eliminate the subjective factor in the diagnosis of normality.
