First off, sorry you crashed! Sounds painful.
Gute besserung!
Regarding why… who knows, and if you don’t remember it all too well, which is understandable given the situation, it will be hard to pinpoint. Personally, I do NOT think it was the wind. As you know, wind can be brutal and can blow you off course, but in my experience it doesn’t turn your wheel. Your overreaction to getting blown off course may do that, but the wind pushes the bike as a unit to the side. Plus, it will exert equal force to the front and back of the wheel, thereby not turning the bars.
I think potentially you hit something, like a rock. I HAVE had that happen before, and an obstacle will turn the wheel quickly.
I would not change the wheels based on this one event. If you lived in an ultra windy place and kept getting blown around and you were sick of it that’s one thing but it doesn’t sound like this applies to you.
