You guys should redo this video. I generally like your stuff but at 17 seconds it is clear that this is a different patient. There is stockinette and padding and a much more involved set up compared to the final product which is just padded plaster.
Super slick. I've watched many of these videos as I transition from a career as an ortho surgical PA to one working in a walk in clinic. I really like that extra thumb hole cut in the stockinette for the final turn down. I'll add that to all my short arm cast variations.
