ABSTRACT
We examined selected parameters of the clotting and fibrinolytic system of 26 boys with aseptic necrosis of the femoral head and then evaluated the pressure of the fluid in the cavity of the hip joint with the help of ultrasonic examination. No disturbances were discovered in the coagulation system and ultrasonography ruled out the possibility that extravascular pressure had caused the necrosis. We confirmed a significantly greater level of alpha 1-antitrypsin in comparison with the control group, which may indicate a decrease in fibrinolytic activity and confirm the hypothesis that there is an intravascular pre-disposition towards the appearance of clots in the vascular system of the femoral head in patients with Perthes' disease.

A detailed case history of a 6 years old child, including biochemical and radiological examinations, has been presented. The disease started with a commonplace contusion of the patella and rapidly progressed after arthrotomy. Dihydroxy-aluminium-natrium carbonicum was applied as well as the low calcium and phosphorus diet. After 4 weeks of treatment, the joint recovered its correct contours; and after further 7 months, only vestigial calcification was observed.
