Aaargh! It is amazing that this doesn't happen more often when you see some of the horrid crashes that they have ...
I hope that she makes a full recovery, but spinal injuries are always very bad news.
If it’s just a matter of broken bones, chances are she’ll make a slow and painful, but full recovery.
If however, the injury has impacted the spinal cord in any way (as my Consultant told me the spinal cord is little more than a strip of toothpaste protected by a very strong skeleton), then it’ll more than likely prove life changing unfortunately.
Best wishes to her in either event for the best recovery possible.
