You may recover very well - not all compression fractures are created equal. The stable patterns with less dispacement and comminution usually have better results than the unstable patterns - see below. Stay positive and follow your doctors advice. And avoid chiropractors. It is a good idea to get bring your x-rays/ct scans for a second opinion from another spine specialist. You may also also want to get a metabolic bone workup to make sure your bone density is adequate.

I know this thread was from a little while ago, but I just received an L1 compression fracture as well. Thankfully the doctor told me it was fairly minor so after a week of bed rest and no brace I'm back at work and regularly in physical therapy. I was just curious about how long it was before you were able to get on a snowboard again?
