title: Expected frequency of femoral neck fractures by fall in the osteoporotic and osteopenic East Slovak female population: Epidemiological study.
abstract: OBJECTIVE
  To compare an expected frequency of pathological FSI values with an expected frequency of pathological BMD (T-score < or = -2.5 SD) in the total hip area in the East Slovak female population.
  
  
  METHODS
  We analyzed the data in the sample of 3,215 East Slovak women with a primary or secondary osteopenia and osteoporosis and with risk factors for osteoporosis, aged 20-89 years, x = 58.9 years, 95% CI (55.15; 60.35). Measured variables: T-score total hip left and FSI left (femur strength index with dual energy X-ray absorptiometry.
  
  
  RESULTS
  In the East Slovak female population we can expect 6.25% of women with osteoporosis in the total hip area and 14.54% of women with FSI <1, i.e. these women will suffer a femoral neck fracture in case of a fall. The expected frequency of the incidence of pathological FSI values of the East Slovak female population is 2.33 times higher than the expected frequency of the incidence of pathological T-score for osteoporosis measured in the total hip area.
  
  
  CONCLUSIONS
  The measurement of FSI variable values may discover a higher percentage of women with a risk of femoral neck fracture by fall than the measurement of BMD variable values in the total hip area. This disproportion shows that even a patient with osteopenia measured in the total hip area may sustain a femoral neck fracture by fall, when she has adverse values of geometric variables of proximal femur (biomechanically unfavourable proximal femur configuration).
