im really not in the mood to get an internet argument, but you seem hell bent on it.
What do you think vertebral disease is, and does it not occur to you that a spinal fusion may be a process by which to treat said disease? Not that it really matters, its just something to throw into the mix when you are thinking, especially if you subscribe to a conservative approach. In assessing this patient I want to know why he had the procedure and how, if at all, it effects anything. That to me is of more value that simply knowing he went under a knife. I get it that it may be lumbar vs. cervical, i get that it is a minor splash of grey...but its still an item we want to explore.
Your right, when they designed the methodology, they picked 65, because thats a commonly used number. They could have analyzed the data out to age 64, 4 months, and 3 days. It really doesn't mean anything more than that. Do you really think that between the morning of your 65th birthday and the time you blow your cake candles out that magic sauce sprinkles from heaven, drips in your ear, and undermines the strength of your cervical spine? Its a freaking number to aid the data analysis. Again, something to think about when deciding on a treatment plan.
The "rule" is just a tool. Its not a be all end all to ruling in or out injuries. Nothing is. No tool we have is perfect. No data, no machine, no diagnostic. We use clinical judgement and the best of science, and a little artistry to treat our patients. One paper, one flow chart, does not necessarily become the gold standard in all things treatment, and allow you to send your brain out to lunch because your MDCalc app on your iphone can just make decisions for you. (As an interesting aside, MDCalc includes the hx of vertebral disease as exclusionary critera.... damn conservatives)
This is why EMS cant have nice things....
