I had a Kyphoplasty on L-2 within a few months after the fracture. My doctor indicated that there is a window of time that it is most effective.
Mine went very smoothly, no side effects and very effective. If I had another compression fracture, I would not hesitate to have it done. It was done at a major academic medical center. Great doctor, easy process.

I have old fractures on L4-5 and unfortunately they happened so long ago (years) that area was not eligible.
