Like several have said, it happened so fast I didn't have time to react. I do know I was still gripping, tightly, both grips. Obviously my left shoulder and left knee took the impact, my right hand injury was (assuming) due to the bar pushing my thumb back beyond its natural range as the right handlebar rotated backwards as the left pushed forwards due to impact.

Tomorrow I have a shoulder MRI to see the extent of damage to my left rotator cuff. I can move my left arm in all directions/ways, just hurts when raised over shoulder level - I think I will avoid surgery on that one.
