Back pain is the leading cause of disability worldwide, but spinal surgery is one of the most over-performed procedures in medicine. The real challenge is knowing when surgery is genuinely the best option and when it's being offered too quickly.
What the evidence actually shows
For many common spine problems — degenerative discs, general lower back pain, mild stenosis — the evidence doesn't clearly favour surgery. Large research studies show that surgery outcomes at 2 years are often similar to structured physiotherapy and pain management.
Clear surgical cases do exist: Cauda equina syndrome (a specific nerve problem) needs emergency surgery. Progressive nerve damage needs urgent review. A confirmed disc herniation causing sciatica that hasn't improved after 6–12 weeks of physio — that's a reasonable surgery candidate.
Get three opinions, not two
Spinal surgeons often disagree dramatically. One recommends fusion, another recommends decompression, a third says no surgery. I always advise clients facing spine surgery to get at least three independent opinions — ideally from different hospitals with different specialties.
Surgeons trained in minimally invasive surgery tend to recommend minimally invasive surgery. Surgeons trained in fusion recommend fusion. Physiotherapy specialists recommend physio. Knowing these patterns helps you make a better decision.
What you must have before agreeing to surgery
Before spinal surgery, you need: clear imaging (MRI or CT) that matches your symptoms; proof that conservative treatment was tried properly; published success rates for the specific surgery on patients like you; and the surgeon's own outcome data.
If any of these are missing, you're making an irreversible decision with incomplete information. More on when a second opinion is essential.
