This seems very unusual on many, many levels. I hate to ask, but were you a child when this happened? If so, are you sure you were in all the conversations. First- There are less than 600 total hip replacements conducted each year on children in the United States. Second- It would be unusual for this surgery to be even recommended without something serious being addressed. Third- Failure to discuss risks and tradeoffs would be regarded as malpractice if something went wrong.
