spine surgery is becoming more and more elective; in fact, i'm noticing many similarities between plastics pp and spine surgery pp.
i haven't looked at the success rates between chiropractry (is that a word) and spine surgery.
nevertheless, after anatomy lab, and viewing several surgeries, one can notice certain things.
first, the vertebral artery dissection makes sense.
second, the spine is really freakin solid+strong
three, brute manipulation by men in anatomy lab still had difficulty contorting the spine
four, just look at a spine surgery
putting it all together, and i'm a larger-than-average guy, i would not be able to permanently contort the spine unless i used all my strength, which no doctor does in treating patients. i don't know chiropractic philosophy, but at this level having learned the spine, dissected the spine, played with the spine, and watch/helped with surgery of the spine, it becomes painfully obvious what one can and cannot do without intervention
as to the rates of vertebral artery dissection, yes it's low, but no one has actually looked at the methodology of the studies. currently, there are a hundred-plus case reports, but when someone comes in with a vertebral artery dissection resulting in rapid quadriplegia and respiratory arrest, the first question we ask is not "did you let a chiropracter manipulate your cervical-spine?"
even if we did a thorough study, the rates will no doubt be low. but let me put it this way. the risks, from what i've seen online, which vary greatly, roughly correlate to the risk of bilateral lasik eye surgery going terribly wrong. so, if you're the type of person who wouldn't get lasik because your eyes are too valuable, and there are many of us out there who get these jitters, would you really be willing to risk a vertebral artery dissection?
