[Contribution of scintigraphy in non-infectious hip diseases in children].

Radioisotopic examination in children's hip disorders permits an approach to vascular pathology, useful in establishing both diagnosis and prognosis. In this paper, particular attention is devoted to Legg-Calvé-Perthes disease, because of the gravity of the sequellae encountered. Acute transient synovitis and its relation to the preceding affection is briefly discussed. Lastly, Meyer's dysplasia, whose pathogenesis is still not certain, is mentioned. An attempt is made to deduce a practical therapeutic attitude.
