I totally smashed my leg up skateboarding and was in traction in hospital for almost two months. My leg was like an S shape. and had it been filmed would've pushed that Unsane video way up into the X Rated category for sure. It's still about a half inch shorter than the other and i suffer constantly from cramp in it. Never been on a board since or had to visit a hospital as anyrthing other than a visiter.
Here's that Unsane video:
