[Modification of skeletal maturation in Perthes' disease (author's transl)].

The authors have observed 34 cases of Perthes' disease to try to discover whether the lesion is an isolated epiphyseal dystrophy or the local complication of a more generalised disease. They found that most of the patients show retardation of skeletal maturation without any of the usual pathological explanations. They consider that perthes' disease is associated with multiple factors including genetic and endocrinological ones causing generalised of cartilage.
