Yikes! Bless your heart. I will add you to my (long and longer) prayer list. :^)
A second opinion might be in line if you have doubts about the osteo surgeon. How do your bones usually heal? Have you had dental implants and, if so, did the bone surround the implant? ...that sort of thing.
If there is some doubt about bone growth vitamin K2 has a reputation for encouraging bone growth. I have taken it after two spinal fusions - given my age. Of course I can't say if it helped - it didn't hinder. 😊 Some also say it helps defend against CoViD.
I broke my left arm, near same place, not as bad, 3 yrs ago and it healed fine. No issues. No surgery. I wore a cast for 2 weeks then cut it off 👀. Wore a splint though.
Had a terrible broken foot 6 yrs ago, but that was 6 yrs ago lol. Took a year to heal.
No dental implants. Teeth are good lol 😁.
I take Vit D and K.
It certainly is a conundrum.
How much K2 does one take for a broken bone?
