Usefulness of bone density measurement in fallers

Area of Science:

• Gerontology
• Orthopedics
• Endocrinology

Background:

• Osteoporosis and fall risk are primary causes of nonvertebral fractures in postmenopausal women.
• Bone mineral density (BMD) measurement via DXA provides crucial fracture risk data, independent of fall risk.
• Osteoporosis prevalence is high in fallers, increasing with frailty markers like sarcopenia.

Purpose of the Study:

• To review the 2012 French recommendation for BMD measurement (DXA) after a fall in postmenopausal women.
• To discuss the rationale behind the recommendation, linking BMD, fall risk, and fracture prediction.
• To highlight considerations for DXA appropriateness, including life expectancy and resource availability.

Main Methods:

• Systematic literature review of the 2012 French recommendation.
• Analysis of the relationship between BMD, fall risk, and fracture incidence.
• Discussion of factors influencing DXA utility in fallers.

Main Results:

• BMD measurement is valuable for assessing fracture risk, particularly when combined with fall history.
• Osteoporosis treatments are effective for fracture prevention only in diagnosed osteoporosis populations.
• Frailty markers are associated with both increased fall risk and osteoporosis prevalence.

Conclusions:

• DXA screening after a fall is supported by the link between osteoporosis, falls, and fractures.
• Life expectancy and DXA availability are critical factors in deciding on screening.
• Further research is needed to integrate fall risk and frailty into BMD-based fracture risk assessment tools like FRAX®.
