RESUMO
A clinicoroentgenological study was performed in 35 rheumatoid arthritic patients (of them 24 with aseptic necrosis of the femoral heads and 11 without clinicoroentgenological signs of the hip joint involvement). Aseptic necrosis, stage II, was roentgenologically defined in 12 femoral heads, stage III in 23. An analysis of the results of the scintigraphic study showed that the RP absorption ratio in the rheumatoid arthritic patients with aseptic necrosis was significantly higher than that in the control group. Significant scintigraphic differences between stage II and III of aseptic necrosis were also revealed (the ratio of 99mTc absorption was 2.79 +/- 0.156 and 4.08 +/- 0.22, respectively).

Clinical, x-ray and scintigraphic investigations were performed in 34 patients with systemic lupus erythematosus (SLE): 24 patients with SLE complicated by osteonecrosis of the head of the femur (the 1st group) and 10 patients with SLE without clinicoroentgenological signs of aseptic necrosis (the 2nd group). Analysis of the results of scintigraphic investigation showed that the coefficient of radionuclide absorption in the SLE patients with suspected osteonecrosis (stage I) as compared to the controls and patients with stage II osteonecrosis of the head of the femur turned out to be significantly discernible (p less than 0.001). Thus, an early stage of osteonecrosis of the head of the femur can be reliably diagnosed by scintigraphy. Quantitative scintigraphy can be effectively used for dynamic observation and objectification of applied therapy.
