Spinal Fusion Rates Continue to Climb
This article from Medscape came across my radar a few days ago, and a number of colleagues had some interesting email dialogue around it (Britt, thanks for initiating the discussion!). The gist of the conclusion is that between 1998 and 2008, the annual number of spinal fusion discharges increased 2.4-fold (137%) from 174,223 to 413,171. In contrast, during the same time period, laminectomy, hip replacement, knee arthroplasty, and percutaneous coronary angioplasty yielded relative increases of only 11.3%, 49.1%, 126.8%, and 38.8% in discharges, while coronary artery bypass graft (CABG) experienced a decrease of 40.1%.
A few points worth considering. First of all, TKA is a close second in growth rate, so clearly there are other surgical procedures that might rival spinal fusion surgery for the “over utilization of the year” award. It would also be interesting to know the percentage growth of spine surgeons compared to other specialties during this same period. In other words, is the rate of increased utilization commensurate with the rate of training spine surgeons? What is definitely clear is that the increased utilization of spine fusion is not commensurate with increasing evidence to support it because none (or very little) exists, especially for chronic pain, which is unfortunately an all too common indication being used to justify doing the procedure.
If you remember our infamous “Whore of the Month” series from a few years ago (George, no worries…we won’t bring it back!), I am afraid spine surgeons (not all of them but certainly the ones doing lots of unnecessary fusion surgeries) might be our first lifetime member because of the frequency with which “bad news” emerges with respect to spine fusion.
I suppose that for the sake of patients with chronic back pain looking for a cure (and willing to be exposed to high risk procedures that offer very little hope for benefit), we can only hope that spinal fusion surgery might soon go the way of coronary artery bypass graft, which is down! As Barb Stevens said in our email dialogue, we should expect to see PT become the safer, less expensive, and more effective alternative to spine surgery just as stents have been to CABG.
What say you?
