Question 1

What is the Meaning of FRAX Score?

Accepted Answer

The FRAX Score, or Fracture Risk Assessment Tool, calculates an individual's 10-year probability of major osteoporotic fracture, including hip, clinical spine, forearm, or humerus. It also provides the distinct 10-year probability of hip fracture. This standardized instrument aids professionals in identifying individuals who may benefit from preventative strategies against bone fragility.

Question 2

What is the Context of FRAX Score?

Accepted Answer

Within skeletal health and bone metabolism, the FRAX Score functions as a key component in evaluating bone fragility. It operates within osteoporosis management, a condition marked by reduced bone mass and microarchitectural deterioration, increasing fracture risk. This tool helps contextualize an individual's bone mineral density (BMD) within their overall clinical risk profile, guiding intervention decisions.

Question 3

What is the Significance of FRAX Score?

Accepted Answer

The clinical importance of the FRAX Score lies in its ability to stratify patients by fracture risk, informing therapeutic choices and improving outcomes. It offers a comprehensive assessment beyond bone density, crucial for preventing debilitating fractures impacting quality of life. Identifying high-risk individuals enables timely pharmacological intervention, reducing the burden of osteoporotic fractures.

Question 4

What is the Mechanism of FRAX Score?

Accepted Answer

The FRAX Score operates through an algorithm integrating several established risk factors for fracture. These include age, sex, BMI, prior fragility fracture, parental hip fracture history, current smoking, glucocorticoid use, rheumatoid arthritis, secondary osteoporosis, and alcohol intake. The algorithm can also incorporate femoral neck BMD, if available, to refine the risk calculation, yielding a probabilistic estimate.

Question 5

What is the Application of FRAX Score?

Accepted Answer

Clinically, the FRAX Score is routinely applied to adults aged 40-90 years evaluated for osteoporosis or bone fragility. Healthcare providers, particularly in primary care, endocrinology, and rheumatology, use this tool to determine if a patient's fracture risk warrants pharmacological treatment, even if BMD does not strictly meet diagnostic criteria. It facilitates shared decision-making, allowing collaborative assessment of intervention benefits and risks.

Question 6

What is the Metric of FRAX Score?

Accepted Answer

The FRAX Score's output is a percentage, indicating the calculated 10-year probability of a major osteoporotic fracture and a separate percentage for hip fracture. Input data is gathered through systematic collection of patient demographics and medical history, including lifestyle factors and relevant medical conditions. If a DXA scan is performed, the femoral neck T-score is incorporated to enhance risk assessment precision.

Question 7

What is the Risk of FRAX Score?

Accepted Answer

Misapplication or misinterpretation of the FRAX Score can lead to inappropriate treatment. Over-reliance without considering other dynamic risk factors, like falls or unlisted medication effects, may result in under-treatment of high-risk individuals or over-treatment of those who might not benefit from pharmacotherapy. It is a predictive tool, not a diagnostic one for osteoporosis, and its results must be interpreted within broader clinical context by a qualified professional.
