I broke my L1 vertebra boarding back in March 2012, and I was back riding again in December. What your looking for is a stable fracture with no nerve damage and only a small amount of kyphosis. When you get out of your brace, make sure to do your PT to regain your flexibility and strength. It's been less than a year and other than having the stamina and strength of a first timer again, i could say I'm 100%.
Just thought I'd share a similar story with a happy ending. Somehow I fathered a child in that brace lol. You never know what tomorrow will bring. Keep your head up!
