Do You Need Surgery for Sciatica? What a 2026 Systematic Review Found

By Dr. Mitch Whittal

Jun 4, 2026

If you or someone you know has sciatica and you’re wondering, is surgery the right choice? The answer may surprise you. Discectomy is still considered the gold standard when surgery is chosen. There are many varieties of the procedure but the gist is that the surgeon will remove some amount of the herniated or bulging material to relieve pressure on the spinal cord or the affected nerve root. A new 2026 review study found that surgery offers real reductions in leg pain and disability in the short term, but for people with acute sciatica, by the one-year mark, outcomes for surgery and conservative care look about the same [1].

What the 2026 review actually compared

A review pulled together results from over 40 studies on lumbar disc herniation, which is the structural cause behind most cases of true sciatica [1]. The headline finding is not that surgery doesn’t work. The point is that the gap between surgery for acute sciatica and conservative care closes significantly as time goes on. At short follow-up of 8-weeks, surgical groups had less leg pain and less disability. That matters because surgery carries upfront risk, recovery time and cost that conservative care does not.

What you won’t see in headlines is that the data used to draw these conclusions is shaky. The "conservative care" in these studies was mostly ‘usual’ care (painkillers, rest, generic physiotherapy, advice, reassurance) not a structured, progressive program. Patients that received painkillers were pooled into the same group as those that received advice, or rest, or physio. I used ‘or’ intentionally there as well. The included studies in the conservative group all featured different forms of conservative care, and none of them were progressively structured exercise programs.

Further, the study that found Acute sciatica and conservative care, which result in similar outcomes long term, featured a crossover design where participants from the conservative care group could opt to receive surgical intervention at any time throughout the duration of the study, and they still treated them as if they were in the same original conservative treatment group [1, 2]. Making this very difficult to interpret. The proper statistical approach was applied, and the authors were working with the data that they had, so no fault there; just an unfortunate reality of the information that we currently have. It’s possible that the effects of surgery were suppressed by the crossover design. From my own experience, I would also bet that a comparison to comprehensive conservative care would alter results yet again. Research isn’t perfect.

When surgery does pull ahead

There is a real role for surgery, and pretending otherwise would be dishonest. The clearest case is severe, persistent radicular leg pain that has not responded to a structured conservative approach, or any red flag like progressive weakness, saddle anaesthesia or loss of bowel and bladder control. Those last three are emergencies and require medical attention immediately.

In my opinion, for people that don’t have red flag symptoms, surgery is a tool best utilized after conservative options have been exhausted.

If your only conservative effort was two weeks of rest and ibuprofen, you have not really attempted a true conservative approach.

What a real conservative trial looks like

This is where I have to be direct. "Conservative care" is not the same as doing nothing. And for sciatica specifically, there is evidence of beneficial conservative care.

A 2025 analysis of 50 different chronic sciatica trials found that exercise combined with nerve mobilization produced some of the largest acute reductions in leg pain of any non-surgical option [3]. A separate analysis of 20 trials found that nerve mobilization on its own meaningfully reduced both pain and disability [4]. Both of these studies suffer from a lack of a comparison to a surgical intervention, just as the surgical study lacked a comparison to a true conservative approach, but the results both point in the same direction, and they point at things that you can do that actually help.

The other half of the message is time. These effects build over months, not days. Most people who tell me conservative care "didn’t work" intended to give it the ‘old college try’ but then stopped or gave up after only a few days or weeks. That is not a failed intervention, it’s an incomplete one.

For disc-dominant sciatica specifically, the conservative approach needs to be tailored to calming the angered nerve, and nerve mobility work, not just generic exercises. The disc and the nerve root are mechanically linked by fact of being neighbours.

How to decide what to do this week

Here is a sequence you can actually run.

  1. Rule out red flags. If you have new bowel or bladder changes, saddle numbness or rapidly progressing leg weakness, stop reading and see a medical professional ASAP.
  2. If not, consider committing to a genuine 16-week conservative approach built around evidence-based approaches including: nerve glides, hip and hamstring mobility, and graded progressive loading. All of these components are built into the Back Again programs and they take the headache out of what to do, how much, and when.
  3. Re-decide at week 16. If leg pain and function are improving, you have your answer. Stick with it. You’re headed in the right direction. If they’re not improving, that is the moment to consider alternative treatments.

Why this matters for the disc-dominant pattern

The nerve-mobility phenotype, which is what most people with classic sciatica fall into, responds well to a specific kind of loading. The mistake I made for years was treating my back like a fragile object and avoiding all the movements that scared me. The disc is a living, adaptive tissue. It needs load to recover (quite slowly unfortunately).

The research is honest about the fact that surgery does help in the short term, and that is real. But the same data shows that the long-term picture for conservative care is comparable for most people with acute sciatica [1]. If you have the runway, the conservative path is almost always worth running properly first.

The bottom line

For most people with sciatica, and no red-flag symptoms (see below), your best bet is to attempt a structured conservative plan first. And give it a genuine attempt. I can only speak for myself, but my radicular pain has decreased dramatically from following the conservative approach outlined in my programs. Surgery is a powerful tool when it is the right tool. It is not the default.

As always, have a great weekend.

Best,

Mitch
