I actually am a physician, and I had a fragility fracture in my spine last January. It was at L1. It came out of the blue, as I have absolutely no risk factors, other than being fair and slender. My T-score was -3.1.

My endocrinologist put me on Tymlos injections (similar to Forteo, both are parathyroid hormone analogs). I've been on those for about 7 months. No real side effects.
I just had a follow-up DEXA 2 days ago, and my T-Score is now -2.1, putting me into osteopenia instead of osteoporosis. I gained a whole point!

I am also in the process of getting a dental implant. The oral surgeon looked up Tymlos online, and declared that it would be OK to proceed with it.

So, for me the therapy has been a smashing success. I have over a year more of it to complete. I'm also lifting weights, have a Power Plate vibration machine, and various supplements.
One caveat: I personally believe that my issue was caused from having Covid four times, and that is why it is correcting so rapidly. I don't think there was an underlying metabolic process.
