Hospital flips? That's almost a freestyle trick, Louie Barletta does one in man down, where you start with your board upside down, your back foot under the tail, and your front foot on the front truck (by now, it already fucking hurts, if you don't commit, it could be potentially hazardous to the well being of your foot, hense the name Hospital flip), and then you lean forward lifting the tail off the ground, balancing on the nose, teetering forward till eventually you flip the board end over end and land on it.
Louie does it into a ditch to tail drag, falls off his board, chases it down and stabs it with a shard of debris.
