You might be interested in reading this journal report on the utility of TBS in osteoporosis management:

Here's a link specifically to the discussion summary of the article: https://erar.springeropen.com/articles/10.1186/s43166-024-00252-x

My takeaway from reading the article is that TBS can be helpful in determining fracture risk but should not be relied on as the only measure for determining how to manage osteoporosis.

I would agree that since your TBS score was included in your FRAX, it did lower your risk. Sounds like good news!

Sounds like a good discussion to have with your doctor on whether you should go ahead with anabolic therapy or if they have other suggestions that don't include medication.
