Why Are Some Doctors Fighting So Hard For Vertebroplasty?
Two randomized controlled trials on vertebroplasty published in the New England Journal of medicine in August of 2009 came to some unexpected conclusions.The first study performed in the United States by David Kallmes, MD of the Mayo Clinic compared the vertebroplasty procedure to a sham procedure in 131 patients in 11 centers. The second study performed by Dr. Rachel Buchbinder of Monash University in Australia compared vertebroplasty to a sham procedure in 78 patients in 4 centers. Neither study found any advantage for the vertebroplasty procedure compared with the dummy procedure.
With the above findings from two independent studies in different countries you would think that there would be a significant decrease in the number of vertebroplasty procedures done in this country, right? Well not exactly, you see the doctors who perform vertebroplasty swear by it, no matter what the research says. Why would they do this? Because they have seen it work time and time again. In fact an article in the Boston Globe in response to these studies suggested that “these findings are unlikely to change the practice of many specialists, who said they don’t jibe with their years of experience”, which is what brings me to my point. Medical research is there as an aide to help doctors do the right thing, to do the best we can for our patients and offer those under our care treatments that are proven effective. Does this mean we don’t do anything that the research has yet to prove? I don’t think so.
Take into consideration spinal decompression, a treatment that has become more and more popular over the past several years. There are studies showing very good results and a high success rate, but opponents of the treatment claim that the research isn’t of high enough quality and there are no RCT (randomized clinical trials) proving it’s effectiveness. Does that mean it doesn’t work? Absolutely not, in fact I have seen it work on thousands of patients like clockwork. Over and over again, patients respond to spinal decompression, and in my program always after other treatments have failed. Now what if a study came out showing that it didn’t work, would I stop offering it? Not on your life!
I bring up this point because clinical experience in my opinion trumps medical research. An effective treatment for any condition is an effective treatment with or without peer reviewed journal articles. Most doctors who don’t have a vested interest appear to be scientifically minded and impartial until you start messing with their livelihood. In reality many aspects of medicine are not as scientifically grounded as you may think. Many of the routine procedures for back pain have not been proven or in some cases have been proven not work. Yet, they are still performed day in and day out.
Now am I saying we don’t need research? Absolutely not, I love research. I look forward to my monthly journals with anticipation. The good news is that a lot of the most recent studies on back pain and disc physiology are helping to support what I have seen in my practice over the years. That is a very satisfying feeling and one that hope helps a lot of back pain sufferers through the years.
