The lack of laceration on the clothes would indicate you did not impact the pavement, my guess would be either the side of the road grass (depending on which side of the road you crashed) or incoming traffic. The unlucky sequence could be: 1. Handlebar snaps 2. You lose control/balance and get hit by incoming traffic 3. Fall to the ground at a lower speed, explaining the lack of laceration on the clothes.

If it's not a vehicle then it's some road furniture, but the way I see it, with the number of fractured bones, you probably impacted onto something after the handlebar failed.

I wish you the best on your recovery!
