[Various forms of lesions of the femur head in Legg-Perthes disease].

The authors described small-focal, limited and disseminated forms of the femoral head affection. They differ in localization and extent of the necrotization foci and don't transform themselves in the course of disease. Comparison of anatomical data, roentgenologic and angiographic examinations allows to infer that the described forms of affection are conditioned by the blockade of the vascular basins of the intraosseous circulatory system of the epiphysis.

[A gamma scintigraphic assessment of blood supply of the hip joint in Perthes disease].

In order to specify the peculiarities of the blood supply of the hip joint in Perthes' disease the authors carried out gamma scintigraphy by 99m Tc-pyrophosphate in 34 children. Patients with roentgenologically confirmed diagnosis of Perthes' disease at various stages as well as those in whom Perthes' disease was suspected, but convincing roentgenologic changes were absent, were examined. The data of scintigraphy and roentgenography were compared.
