One more thing to add, this has happened to me 3 times, without that plastic there, and i was all right. Im all right now. The ortho doctor put my leg back in, and he put a peice of metal in.
EDIT: its 3 months later and im all right, i can walk, and in 2 weeks i can run. ill start parkour in the gym only. EDIT 2: Turns out my dad doesnt even want me to go to the gym, so screw it. :D 9 months after surgery, leg still swelling like month one. That cant be right.
