[Dynamic angioscintigraphy and static scintigraphy of the hip joint in the complex diagnosis of Legg-Perthes disease].

The author has studied the peculiarities of the initial passage of an osteotropic radiopharmacologic drug along the femoral arteries and its distribution in the femoral head in 55 children with Perthes' disease and in 25 children with diseases and injuries of the hip joint with similar symptoms as well as in 22 children from the control group. In normal conditions the asymmetry of the drug distribution does not exceed +/- 10%. The presence of the drug hypofixation focus (the relative level being below 90%) in the upper pole of the femoral head associated with a reduction of the blood flow in the femoral artery on the affected side is typical for the early stage if Perthes' disease. These symptoms precede the appearance of the roentgenologic signs of the femoral head lesion.
