Routine Application of the Korean FRAX Model in Women: a Single-center Study

ABSTRACT

OBJECTIVES: The objective of this study was to assess the efficacy of the Korean fracture-risk assessment tool (FRAX) model for routine application in women who had a general check-up for bone mineral density (BMD). METHODS: This retrospective study was conducted at a university hospital and comprised 343 patients, whose BMD and clinical risk factors were assessed for FRAX calculation. The 10-year probabilities of hip and major osteoporotic fractures were compared with the result of the FRAX(R) tool (http//www.shef.ac.uk/FRAX, web version 3.5) applied to Korean models developed at the World Health Organization Collaborating Center with or without femoral neck bone mineral density. RESULTS: The T-score gradually decreased with increasing age. Additionally, the 10-year probability of a major osteoporotic fracture increased with age. However, the probability of hip fracture showed no correlation with age if BMD was not included in the estimation. CONCLUSION: Previous report on patients whose probability of a proximal femoral fracture were calculated using Korean FRAX models produced a higher score than our data because our data involved a general population. A larger general population is needed to confirm the Korean FRAX model. However, our data provide information for physicians to assess the Korean FRAX model in the general female population.
