When I was a teenager, I fell off a cliff in Yosemite, burst fractured my L5 vertebra into 32 pieces.
I do have some low back pain, but no more than an average 39-year-old. It has not affected my life--dual-sporting, backpacking, manual labor, more rock climbing, martial arts, I've done it all.
Hopefully you can get the bone-cement patch, do lots of good PT, and be back to it in time.
