From everything I've read of various patient's outcomes, it seems to me that surgeons occasionally take great leeway with the device labeling and indications.
But, that begs the question for patients: How do YOU know what the limitations are, indications, generally accepted practices? Are you to just 'trust your doctor?'. Sure, that's fine for those who have excellent outcomes, but for others, wherein it is patently obvious that the surgeon has pushed the limits, if not exceeded them, how do you know what is normal and acceptable?
Go ask another surgeon? Well, that doesnt work very well, especially if they wont implicate a colleague - for fear of retribution.
Here's a post by Dr. Peloza on Spine Universe which will, just by the nature of the questions being asked, give you goose-bumps:
http://www.spineuniverse.com/debate/index.php/topic,11.0.html"Regarding whether or not sham surgery as a control is ethical... First off I understand the reason for a sham surgery control but you can get data that proves the point without doing a sham surgery. I was part of the IDET study, but that was just putting a needle next to the disc, not actually cutting into the patient. If doing a randomized trial involves sham surgery and if this means we have to do a surgical approach, then I think that is very problematic, especially in the U.S. I can’t imagine patients who have free access to healthcare would randomize to this and agree to be part of the randomized group. Secondly, no hospital IRB would approve and I don’t think any surgeon or patient would agree to be part of it. I think it is an ethical challenge and would face all kinds of legal hurdles."
For example: In the FUSION VS. ADR debate, we hear variably that less than 5% and greater than 90% of fusion patients are candidates for ADR. They cant both be right.
This thread will focus further on sources and means to discover these bounds.
