There's a spinal surgery billboard on a major road near my house, and I have a few thoughts: 

1. I don't live in or near a population center, and spinal surgery is pretty damn specific, so how many people who are in the market for spinal surgery are really seeing this?
2. Who is the target audience here?  It's not like people see this on their commute and think "ya know what, I could use some spinal surgery".  Non-experts don't typically provide advice or recommendations on surgery, especially SPINAL surgery.
3. Even if a person had a back problem and went to a doctor who recommended spinal surgery, we live in the United States healthcare system, which means there's a whole mess of complications regarding where you can get care and who can provide it.  There's almost zero chance a prospective patient will be able to choose to go to this spinal surgery center.

In conclusion, I'd prefer to get my spinal surgery from someone who spends their advertising dollars a little less frivolously. #health
