Which event triggered the osteoporosis risk discussion in this case?

• A. A Colles' fracture sustained during hiking
• B. Routine check-up
• C. Family history of osteoporosis
• D. A sprained ankle

Answer: (A)

A fracture from a low-energy fall, like a Colles' fracture of the distal radius, is a red flag for osteoporosis. When an older adult sustains a wrist fracture from a simple fall during activities such as hiking, it often indicates underlying bone fragility rather than just an isolated injury. That fragility fracture prompts a discussion about osteoporosis risk, prompt evaluation of bone density, and steps to prevent future fractures through treatment and lifestyle changes.

The other options don’t inherently signal compromised bone strength: a routine check-up is a general health encounter, family history is a risk factor but not an event that reveals bone weakness, and a sprained ankle is typically an acute soft-tissue injury rather than a fracture due to osteoporosis.
