Fracture Risk Assessment: Question Three
Your answer is incorrect. The correct answer is C.
With further questioning, you find out the following about your patient:
- Weight 150 pounds (height 65 inches)
- Alcohol: 3 glasses of wine each night
- No corticosteroid usage (past or present)
- No personal history of a fracture
- Smoking: 1 PPD
- No family history of a hip fracture
You decide to use the FRAX tool to determine her fracture risk given her many risk factors. You have a question about the FRAX tool as you are putting in the data.
Can the total hip BMD rather than the femoral neck BMD be used in the FRAX tool?
- Option A No, you must use total hip BMD
- Option B Yes, these are interchangeable
- Option C Yes, but these are only interchangeable for women and not for men
- Option D No, it is best to leave it blank
Can the total hip BMD rather than the femoral neck BMD be used in the FRAX algorithm?
The FRAX model is constructed from population-based cohorts using femoral neck BMD. However, the total hip BMD can be used interchangeably with femoral neck BMD in women, but not in men (1).
