FIELD: medicine.
SUBSTANCE: method involves carrying out two-photon X-ray absorbtiometric examination. Mineral density of femoral bone tissue is determined from scanograms. Length and width of femur neck, femur neck index and femur fracture risks are determined from life anamnesis as early menopause, forearm fractures, low weight and body mass index, hard physical work conditions, low motor activity. Their gradations are set as 0 for no, 1 for yes and numeric values. Then prediction coefficient F1 and F2 are determined from formulas: F1=-7.27 + 1.38*A1 + 1.98*A2 - 1.25*A3 + 4.70*A4 + 3.36*A5 + 1.08*A6 + 2.88*A7 + 2.71*A8 + 0.42*A9 + 1.32*A10 + 4.55*A11 + 3.16*A12 + 3.55*A13; F2=-1.17 + 0.66*A1 + 0.55*A2 - 0.67*A3 + 1.47*A4 + 1.57*A5 - 0.62*A6 + 1.37*A7 + 1.14*A8 - 1.01*A9 + 0.94*A10 + 2.06*A11 + 1.55*A12 + 1.24*A13, where A1-12 are the gradations and risk factors numeric values of two-photon X-ray absorbtiometric data. When F1 ≥ F2 , high risk of femur fracture is to be predicted. When F1 < F2 , low risk of fracture is to be predicted.
EFFECT: high accuracy of prediction.
