Replying to Back arthritis at 24

Had an X ray done on my back following a crash and though there is no acute sign of damage (as in from the crash), it seems I have worn down the top of my L3, most likely from hitting so many jumps over the years. Wtf is that about, arthritis?! Out of all the things I thought would put me out of freeskiing, the last thing I considered was back arthritis (at 24 no less...). Has anyone else dealt with this? Is there any study linking early arthritis to jump skiing? Really don't want to blame this on skiing but my doc doesn't think it could be anything else...
