Spinal Stimulators After Failed Back Surgery: What’s the Success Rate?

There are few things more disheartening than going through back surgery with hope for relief—only to find that the pain persists. If you’ve experienced this, you’re not alone, and you’re certainly not without options. Many patients feel frustrated, confused, or even dismissed when their symptoms continue after a technically “successful” procedure. But persistent pain after surgery doesn’t mean you’re out of solutions. In fact, it often means we simply need to target the true source of discomfort more precisely.

This ongoing pain is commonly referred to as Failed Back Surgery Syndrome (FBSS). Despite the name, FBSS doesn’t necessarily mean the surgeon did anything wrong. Rather, it means the underlying pain generator wasn’t fully resolved—or in some cases, surgery led to new issues such as scar tissue, nerve irritation, or changes in spinal biomechanics.

One of the most encouraging advancements for people with persistent pain after back surgery is Spinal Cord Stimulation (SCS)—a minimally invasive, non-opioid treatment that has helped thousands reclaim functionality and quality of life. And for many patients with FBSS, it has become one of the most successful next-step solutions.

What Is a Spinal Cord Stimulator?

A spinal cord stimulator (SCS) is a small, implantable device designed to help manage chronic back or leg pain by changing the way the body experiences discomfort. Unlike medications that circulate through your entire system—or additional surgeries that may not address the root cause—an SCS works directly with your nervous system to reduce pain at its source.

How Does a Spinal Stimulator Work?

Think of it as a “traffic controller” for pain signals. Normally, injured or irritated nerves send pain messages up through the spinal cord to the brain. An SCS gently interrupts those signals before they reach the brain, reducing the intensity of what you actually feel.

Modern stimulators offer advanced features, including:

  • Burst stimulation, which mimics natural nerve firing patterns
  • High-frequency stimulation, which provides relief without tingling sensations
  • Programmable settings tailored to your daily activity and comfort

A Minimally Invasive, Non-Opioid Solution

One of the biggest advantages of an SCS is that it's far less invasive than another spine surgery. The trial phase, where leads are placed temporarily, allows you to “test drive” the therapy before committing to a permanent implant. Many patients see significant improvement within days.

Because spinal stimulation directly modulates nerve activity, it also helps patients:

  • Reduce dependence on pain medications
  • Improve mobility and function
  • Sleep better
  • Return to activities they once avoided

When Is a Spinal Stimulator Recommended After Failed Back Surgery?

Who Is the Ideal Candidate?

Chronic pain has persisted for more than 6 months

Especially if it continues despite a prior surgery or conservative care.

Pain relief has been limited with PT, injections, or medications

If you’ve tried several treatments and still feel stuck, SCS offers a different mechanism—and often, better results.

You want to reduce reliance on opioid medications

Many FBSS patients find that medication no longer provides meaningful relief. Spinal stimulation offers a non-opioid, minimally invasive option to help regain control.

When Spinal Cord Stimulation May Not Be Recommended

While SCS can be incredibly effective, it may not be advised if:

  • There is active infection
  • Severe, untreated psychological conditions are present
  • A patient is unable to undergo even minimally invasive procedures
  • The type of pain does not align with conditions known to respond well to SCS

The Success Rate: What Do Studies Show?

Overall Success Rates

Research shows that 50–70% of patients experience significant, long-term pain reduction with a spinal cord stimulator. But it’s important to understand success as more than a number on a pain scale.

Pain Reduction

Most patients experience a 50% or greater decrease in pain intensity, often within days of their trial.

Functional Improvement

Reduced pain means patients can walk farther, sit longer, sleep better, and return to activities they once avoided.

Quality-of-Life Gains

Many people report improved mood, better productivity, and a renewed sense of independence—benefits that ripple into relationships, work, and daily living.

Success Rates Specifically for FBSS Patients

For individuals with FBSS, spinal cord stimulation often outperforms repeat surgery.

Studies show that FBSS patients who undergo SCS are more likely to:

Experience Major Pain Relief

A large percentage achieve 50%–70% pain reduction, and many maintain benefits for years.

Return to Normal Activity

Patients often report improved mobility, greater activity tolerance, and enhanced daily functioning.

Reduce or Discontinue Opioids

Because SCS changes how the nervous system processes pain, many people are able to significantly cut down on medication—and in some cases, eliminate opioids entirely.

The Trial Phase

Before a permanent implant, patients undergo a trial procedure, where temporary leads are placed and connected to an external stimulator. You get to live your life for several days—with the device working—so you can see how much relief it truly provides.

What Counts as Success?

A successful trial typically means:

  • 50% or more pain relief,
  • noticeable improvement in mobility, or
  • meaningful reduction in medication use.

New Technology vs. Traditional Systems

Spinal cord stimulation has evolved dramatically over the past decade. Today’s systems are more effective, more customizable, and often more comfortable.

High-Frequency vs. Tonic Stimulation

  • High-frequency SCS delivers relief without tingling sensations.
  • Tonic stimulation offers patterned pulses that can modulate nerve activity in different ways.

Rechargeable vs. Non-Rechargeable Devices

Rechargeable systems often last longer and offer more programming flexibility.
Non-rechargeable systems are lower-maintenance and ideal for patients who prefer simplicity.

Better Technology = Higher Success Rates

Newer devices deliver more consistent pain relief, fewer side effects, and expanded options for patients with complex pain—especially those suffering from FBSS.

What Does the Spinal Stimulator Procedure Look Like?

The Evaluation

Before recommending SCS, we begin with a comprehensive assessment, including:

A Detailed Exam

We assess your movement, pain patterns, nerve function, and overall mobility.

Diagnostic Testing

Imaging and nerve studies help us pinpoint the exact source of pain—critical for predicting success.

Review of Prior Surgical History

Understanding what was done, why, and how your body responded helps us create a tailored plan.

The Trial Procedure

Minimally Invasive Placement

During the trial, thin leads are placed through a needle (no large incisions), and an external battery powers the system.

What Patients Feel

Most people describe a sense of relief almost immediately, and the process is far easier than they expected.

Real-World Testing for Up to a Week

You can walk, work, sleep, and go about life with the trial system—allowing us to measure true effectiveness before moving forward.

Permanent Implantation

Outpatient Procedure

If the trial is successful, the permanent stimulator is implanted through a small incision as an outpatient surgery.

Recovery Timeline

Most people return to light activity within days and full activity in several weeks.

Follow-Up & Device Adjustments

The device can be adjusted over time to match your activity level and pain patterns—ensuring ongoing relief as your body heals and changes.

Finding Hope After Failed Back Surgery

Persistent pain after back surgery can feel overwhelming—especially when you’ve already invested time, hope, and energy into recovering. But the truth is this: your journey isn’t over, and relief is still possible. Failed Back Surgery Syndrome doesn’t define your future, and you are not expected to simply “live with it.”

Spinal cord stimulation offers a proven, modern, and minimally invasive path forward. It works differently than traditional treatments by directly targeting the way your nerves communicate pain—allowing many patients to reclaim movement, sleep, and the ability to enjoy their lives again. For countless individuals, SCS has been the turning point they desperately needed.
