I've had a few,they include;
Broken & dislocated collarbone
3 1/2 inch boone-deep gash in shin through body armour!
Chunk out of skull hitting a dry-stone wall in the pyrenees - luckily I had gone through a thorn bush first!
Several broken/cracked fingers including two knuckles on trees
Two broken toes
Cut a hole through my calf with a broken chainstay as I accelerated to overtake a car
4 inch long hole in right calf from a chainring
2 inch scar on elbow after brake-lever puncture and tear.
Miscellaneous tendon/muscle damage
Countless other scars from trees/thorns/rocks/ground/pedals/bike on legs, arms & body.
**Edit** I've scared myself a bit with this list
