The art of medicine oesn't involve insanity--although the elbow-leg rhetorical example you give actually DOES reflect certain procedures, not often used today, to keep tissue alive by grafting one portion of tissue to another with a healthier blood supply.
Any patient can ask for a copy of a waiver; they are pretty standard and most offices buy them by the carton, filling in any personal info required. One's personal physician probably uses the same forms, and any decent lawyer already knows what needs to be in there. However, the form MUST be signed the day of the procedure.
It took you a year to come up with this pathetic response, and I'M the moron? Sorry, but no.
Your thinking is immoral, or you're a plastic surgeon, which pretty much amounts to same thing. The versions of the Hippocratic Oath differ in style of language, not in content or purpose. Violation of the "do no harm" precept doesn't require that you do the harm on purpose; being reckless or careless is enough. I'm glad you refer to the antiquity of the Hippocratic Oath, because in that case there's another term just as ancient that you plastic surgeons never fail to invoke whenever you screw up: "Art." Whenever you butcher someone the first thing you do is take refuge behind the murky ambiguity of a phrase "art" or "healing art". You could sew a person's elbows to his knees and get away with it by claiming that to be a function of your "art", or lack thereof. I'll tell you how to reduce plastic surgery disasters. Instead of the plastic surgeon waiting until the day of the surgery to show the patient the informed consent--moments before they're led into the operating room--require him to give it to the patient with enough time in advance to have the patient's primary care doctor and family lawyer review it. I know I called you a plastic surgeon. Did I call you a moron? I intended to.
