Adding to this article (I'm not a medical professional and not giving advice), the same inferior medical outcomes are attributed to most, if not all forms of back surgery. Physical therapy outperforms most or all back surgery with much fewer side effects, etc. This is covered extensively in the book How Doctors Think (https://www.amazon.com/How-Doctors-Think-Jerome-Groopman/dp/...) as well as articles like this Ars Technica one: https://arstechnica.com/science/2017/02/doctors-lower-back-p.... You see the same with exercise outperforming anti-depressants in most cases, again with much fewer side effects. (For example: https://www.theatlantic.com/health/archive/2014/03/for-depre...)

The kicker is that doctors will often refuse these same treatments when offered, which is not a good reflection on their efficacy (again covered in How Doctors Think). This is not an indictment of modern medicine (which is often very effective on acute care), just a recognition of the limitations.

Similar topic: "How Doctors Think" (http://www.amazon.com/How-Doctors-Think-Jerome-Groopman/dp/0...) is a great book. Amazon blurb:

"How Doctors Think is a window into the mind of the physician and an insightful examination of the all-important relationship between doctors and their patients. In this myth-shattering work, Jerome Groopman explores the forces and thought processes behind the decisions doctors make. He pinpints why doctors succeed and why they err. Most important, Groopman shows when and how doctors can -- with our help -- avoid snap judgments, embrace uncertainty, communicate effectively, and deploy other skills that can profoundly impact our health."
