20 to 70% of the surgeries that used BMP-2 showed some sort of BMP-2-associated complications
I wonder how many patients have been told about this when the procedure is recommended. It may be the case, as you suggest, that few alternatives exist, but still, a patient has a right to know going in what the downside of a procedure is.
I think even the surgeons are not fully aware of the side effects of BMP-2 because they are often overlooked in scientific literature
