[Etiological assessment of aseptic femoral head necrosis from blood serum metabolic parameters (author's transl)].

The etiological assessment of aseptic femoral head necrosis in adults is facilitated by investigation of the uric acid level and of fat metabolism parameters. From 98 of our own patients it appears that femoral head necrosis after trauma, irradiation therapy and caisson disease and after massive doses of cortisone only exceptionally shows pathological serum levels. Femoral head necrosis with manifest metabolic diseases shows 53.3% hyperuricemias and hyperlipemias or dyslipidemias. Of femoral head necroses without concomitant diseases, prior physical effects and administration of cortisone, 91% had hyperuricemia and 65% hyperlipemia or dyslipidemia.
