Replying to Broke my thumb on ski bindings

Allright, i got my new skis in with the look p18 bindings and the have a bar in the back of the bindings. My thumb was on the bar and then i tried to pull the hellpeice up to click in to see what it was like and it snapped my thumb, while i couldnt get it out, stuck in between the bar and the thing that goes up. Haha i no im an idiot but hey first time with racing bindings, broke my thumb in three places aint that a bitch!
