I need my character to suffer a fall that will lead to a below-knee amputation of her left leg. She's at a concert, either on stage or getting to the stage through somewhat risky measures. Right now, I basically have her falling from a catwalk ladder, but I'd prefer if she could do something like stage-diving. I'm imagining she leaps off the stage, leads with her leg, isn't caught, drives the bone up in her leg for an open fracture, and then potentially has it stepped on (mosh pit!) because I'm not sure the fall would be from a great enough height to do it by itself.
Any thoughts? Anything she could do in a club/concert atmosphere that would be something a girl desperate to get herself and her guitar noticed would be good.
