That's unluncky mate, But i was practising on my motorcross bike and went round corner and fell of awkard and no-one knew what i had dont, They said they thought i broke my leg or dislicated my knee its turned out i had Dislicated my Hip and my leg was completly free out of my hip joint so my leg was freely to move however it liked. I got a helicopter ride so that was awesome, But i stayed in hospital for 3 weeks, 6 months on wheelchair, and another 2 months on cructhes so i know how it feels.
