[Osteopenic syndrome in liquidators of the aftereffects of the accident at the Chernobyl power plant].
Bone system was examined in 112 liquidators; in 71 of these osseous tissue density was studied by osseous densitometer using bienergetic x-ray absorptiometry and in 45 x-ray examinations, analyses of biochemical and hormonal parameters were carried out. Spinal painful syndrome was detected in 61 to 82% of the examinees. For analysis of densitometric and x-ray parameters the liquidators were divided into 2 groups: group 1 included those who worked at the power plant in 1986 (55%) and group 2 were those who worked there in 1987-1989. Radiation doses in group 1 reliably surpassed those in group 2 (p < 0.001). Bone mineral density in the lumbar vertebrae was significantly lower in group 1 as against group 2 and lower in both groups vs. controls. More than 5% osseous mineral loss was revealed in 73% of group 1 liquidators and in 43% of group 2 ones. Analysis of spinal roentgenograms in 45 liquidators showed a high incidence of negligible and moderately expressed osteoporosis without compression fractures of vertebral bodies: osteopenia signs were found in 87% of group 1 examinees complaining of pain in the spine and in 73% of group 2 examinees; signs of osteochondrosis and spondylosis were detected in 40% of group 1 and in 47% of group 2 subjects. Hence, a higher incidence of osteopenia in liquidators, more manifest condition and its higher detection rate in subjects exposed to higher radiation doses indicate a certain contribution of radiation factor to the development of the osteopenia syndrome in liquidators.
