Failed back surgery syndrome is a tough topic. It's not something I approach lightly, because the patients who come to us with this diagnosis are often in a dark place emotionally. They had surgery. They thought it would fix the problem. And instead, they're still in pain — maybe less, maybe the same, sometimes even more. They feel like they've used their last option. They feel hopeless.

I see that a lot in this clinic. And one of the most important things I tell these patients is that the fact that surgery didn't solve the problem doesn't mean they're out of options.

Defining Failed Back Surgery Syndrome

FBSS is defined as persistent or recurrent pain after spinal surgery. The pain could be in the same location as before surgery, or it could be new pain. It could develop immediately after surgery or months or even years later.

How common is it? The numbers vary depending on the study and the type of surgery, but roughly 10 to 40% of patients who undergo spinal surgery experience FBSS. That's a significant percentage. And it represents thousands of frustrated patients trying to figure out what to do next.

The Common Culprits

FBSS has several different causes, and understanding which one you have matters for determining what to do about it.

Scar tissue, or epidural fibrosis, is probably the most common cause. When you have spinal surgery, you create inflammation. Your body responds by forming scar tissue. In some patients, this scar tissue becomes excessive and forms adhesions around the nerve root. These adhesions can restrict nerve movement, cause tethering, and create ongoing pain.

Another common cause is adjacent segment disease. You have surgery at one level — say, L4-L5. But the vertebral segments directly above and below that level have to work harder now to compensate for the operated segment. Over time, they degenerate. The discs bulge or herniate. Bone spurs develop. New nerve compression develops at adjacent levels. Some studies suggest this is a natural consequence of spinal fusion surgery, which limits motion at the fused segment.

Recurrent herniation is another possibility. The disc at the operated level herniates again, either at the same spot where the original herniation was or at a different location within the same disc.

Sometimes the surgery was incomplete. The surgeon addressed part of the compression, but not all of it. Or the surgeon operated on the wrong level. These things happen, and unfortunately, they're not always discovered immediately.

The Emotional Reality

I want to acknowledge something that's not always discussed in medical literature but is very real in my clinic: the emotional toll of FBSS is significant. Surgery represents hope. It's an invasive procedure — you're having someone cut into your spine — and patients consent to that risk because they expect meaningful relief. When that relief doesn't materialize, the emotional response can be devastating.

Patients often feel a sense of betrayal. They trusted the process, followed all the recommendations, did their recovery, and it still didn't work. Some feel trapped, like they've played their last card. Some question whether any treatment will ever help.

This is why I try to be very clear with FBSS patients: surgery wasn't necessarily wrong. The spine is complex. It doesn't always heal the way we hope. But that doesn't mean you're hopeless.

How VAX-D and Decompression Therapy Can Help Post-Surgical Patients

For patients with FBSS who haven't had hardware implanted (rods, screws, cages, artificial discs), decompression therapy can sometimes be helpful. Not always, and I'll be honest about that. But sometimes.

If scar tissue is the problem, gentle decompression cycles can mobilize the nerve root, work against those adhesions, and improve nerve mobility. The cyclic distraction and relaxation of the decompression protocol can break up some of that fibrosis and improve outcomes.

If adjacent segment disease is causing pain from a herniated disc above or below the surgical level, that herniation might respond to decompression therapy just like a non-surgical herniation would. We can create negative intradiscal pressure to retract that new herniation.

For recurrent herniations at the same operated level — the disc herniates again — decompression might help prevent another surgery, or at least provide enough improvement that surgery becomes unnecessary.

Critical Constraints: Surgical Hardware

But here's the hard limit: if you have hardware in your spine, decompression is generally not appropriate. Rods, screws, pedicle screws, cages, artificial discs — these all restrict spinal motion. Decompression therapy relies on controlled distraction and relaxation. Hardware interferes with that. So patients with instrumented fusions typically aren't candidates.

Before we ever recommend decompression therapy for a post-surgical patient, we review their surgical records and current imaging carefully. We need to know exactly what was done, what hardware is present, and what the current problem is.

Our Evaluation Process

With FBSS patients, our evaluation is more thorough and more cautious than it is with non-surgical cases. We review the surgical operative report. We compare pre-surgery and post-surgery imaging to see what changed. We assess current imaging to understand current pathology. We take a detailed history of when the pain started relative to surgery, whether it's the same pain or new pain, whether it's improving or worsening.

Only after all of that do we decide whether decompression therapy makes sense, or whether we need to recommend something else — maybe physical rehabilitation, maybe a referral back to the surgeon for evaluation, maybe pain management consultation.

Realistic Expectations for Post-Surgical Patients

I'm going to be honest here because these patients deserve honesty: post-surgical patients often respond more slowly to decompression than non-surgical patients do. The tissues have been disrupted by surgery. Healing has happened, but it's often imperfect. Scar tissue is present. The anatomy has been altered.

Because of this, patients with FBSS might need more sessions than typical patients. They might experience slower improvement. And complete pain elimination might not be realistic even with optimal treatment. The goal often isn't zero pain — it's meaningful improvement in function and quality of life.

A patient who had surgery and now has 6 out of 10 pain and significant functional limitation might improve to 2 to 3 out of 10 pain with good function. That's a dramatic improvement in quality of life, even if the pain isn't completely gone.

A Message of Hope

Here's what I want FBSS patients to know: having spinal surgery doesn't mean you're out of options. It doesn't mean you're destined to be in chronic pain. It doesn't mean there's nothing else that can help.

Surgery is a legitimate treatment for certain spine problems. When it works, it's wonderful. When it doesn't work as hoped, it's disheartening. But it's not a dead end.

Patients with FBSS have options. Non-surgical decompression therapy. Rehabilitation and physical therapy focused on post-surgical recovery. Pain management strategies. In some cases, revision surgery might be appropriate. In other cases, learning to manage persistent symptoms with the right tools and support might be the answer.

The key is not giving up and assuming that because one treatment didn't solve the problem, no treatment ever will. That's not how medicine works. That's not how healing works. Sometimes the answer isn't the first treatment you try. Sometimes it's the second, or the third, or a combination of approaches.

If you've had back surgery and you're still struggling with pain, we'd like to help figure out what might work for you. That starts with an honest evaluation of what happened during surgery, what the current problem is, and what realistic options exist. You don't have to accept chronic pain as your fate. You have options.
