When do you recommend using trabecular bone score (TBS) for managing osteoporosis?

In which clinical scenarios below would you consider ordering a TBS for better risk stratification?

• 75 yo F with very high FRAX scores (25% for hip fractures and 35% for major osteoporotic fractures significantly increased by history of parent hip fracture) but no personal fracture history
• 78 yo F with very high FRAX scores and a recent vertebral fracture
• 64 yo M with worsening osteopenia but FRAX scores below the indicated threshold for treatment (2.9% for hip fractures and 19% for major osteoporotic fractures)
• Other
