[Scintigraphy examination in differential diagnosis and evaluation during the course of Perthes disease].

Forty-four bone scintigraphies were done in 37 children with diagnosis or suspicion of Perthes disease. In 5 children with transient coxitis 3 hips were normal and 2 presented slightly increased uptake. In 13 cases of epiphyseal dysplasia 12 hips were normal; one presented decreased uptake. Nineteen Perthes cases showed typical uptake deficits; 3 joints showed slight increase of uptake, 3 joints were normal. Scintigraphy was related to different stages of Perthes disease. The value of bone scintigraphy in Perthes differentiation and monitoring was discussed.
