Something very similar to that just happened to me. Very long story short - I was hit head on by another cyclist, the impact propelled me forward and head first into a 6 rail metal guardrail, as I hit the railing the handlebars went through my stomach and came out my inner thigh. This was with a road bike! Along with that injury, my eyebrows were cut open from my glasses requiring 6 stitches each, I had road rash like crazy, bruised from head to toe, tore the muscle in my left upper thigh, and $500 worth of damage to my bike.

Bad part about all this - it was the last training ride before I was to participate in the MS150 from Houston to Austin.....I just got back on my bike 2 weeks ago.
