Возможности непрямой компьютерной денситометрии изображений рентгенограмм в оценке гонартроза

The dynamics of the mean optical density (MOD) of femoral and tibial epiphyses and metaphyses shadows for gonarthrosis has been studied using indirect computed densitometry of X-ray images. MOD of epiphysis shadow increased, while that of metaphysis shadow – decreased depending on progressing the degenerative-and-dystrophic involvement of the joints. The structures of low and mean mineralization degree prevailed in femoral and tibial epiphyses of patients with compensated and subcompensated form of gonarthrosis, and those of mean and high mineralization degree – in patients with gonarthrosis decompensated form. The structures of low mineralization degree prevailed in femoral metaphysis of patients from all groups. The structures of mean mineralization degree prevailed in tibial metaphysis of patients with compensated and decompensated gonarthrosis forms, and those of high mineralization degree prevailed in patients with subcompensated gonarthrosis form.
