Independent Patient Guide

Looking for a Spinal Fusion Alternative for Spinal Stenosis?

Q: How should I use the candidacy page?

Use it to organize symptoms, imaging, prior treatments, and questions before a visit. It does not determine whether any procedure is appropriate.

A spinal fusion alternative for spinal stenosis may be part of the discussion after surgeons make room for compressed nerves. Fusion is one way to stabilize the lumbar spine, but it is not the only reconstructive option discussed for every person. This independent guide explains the main pathways, including fusion versus TOPS, so you can ask better questions - not so a website can choose a procedure for you.

Evidence-based information

Clinical numbers on this site come from regulatory documents and published research, with limits stated next to the result.

FDA and clinical sources

The TOPS System has an FDA Premarket Approval file. Study design, results, and caveats live on the clinical evidence page.

Clear treatment comparisons

Fusion, decompression, and TOPS are compared as different jobs after nerve compression is treated - not as a contest with a preset winner.

Treatment landscape

Stenosis surgery is not one procedure

Lumbar spinal stenosis is a narrowing around nerves in the lower back. Standing or walking may bring on leg pain, heaviness, or numbness that eases when you sit or lean forward. That pattern is a clue, not a diagnosis. Imaging and a clinician still have to say what is going on.

If surgery enters the conversation, the first mechanical job is often decompression: making more room for the affected nerves. When people search for a spinal fusion alternative for spinal stenosis, what happens next is a separate question.

Some are treated with decompression alone. Some are offered fusion, which joins a spinal level so it no longer moves. Some selected patients are discussed for TOPS, an implant meant to stabilize that level while keeping some motion.

Those are different reconstructions, not three names for the same operation. The fusion versus TOPS comparison explains the practical difference. The clinical evidence page explains what FDA reviewed for TOPS, and what that review did not prove.

Comparison preview

Fusion vs. TOPS, at a glance

Read the full comparison

High-level preview comparing spinal fusion and TOPS. Not a complete clinical comparison.
Topic	Spinal fusion	TOPS (motion-preserving)
What it is trying to do	After decompression, join selected vertebrae so that level no longer moves.	After decompression, stabilize the level with an implant designed to allow some controlled motion.
Motion at the treated level	The level is meant to stop moving after it heals.	The level is meant to keep some movement. How that compared with fusion in the FDA study is on the clinical evidence page.
Who it is discussed for	Often when a surgeon thinks that level should be immobilized because of instability, alignment, or other findings in the record.	Discussed for selected stenosis patients who may meet the labeled indication. A website table cannot decide that.

This is a preview. The full comparison, including what to ask in clinic, is on the fusion versus TOPS page. Trial percentages belong on the clinical evidence page.

Clinical evidence

What the FDA actually reviewed

FDA approved the TOPS System in June 2023 after a randomized U.S. study comparing TOPS with lumbar fusion in a defined group of patients. That result is important. It is also tied to a composite success score, a two-year look, and the people who were eligible for the trial.

Read the clinical evidence

What you will find there
The approved indication, how the trial was designed, the 24-month composite result, safety findings, and the limits of that evidence.
What you will not find
A promise that TOPS is right for every stenosis patient, or a ranking of surgeons and hospitals.

Patient relevance

Symptoms people often discuss with their doctor

Many people begin looking for answers when walking or standing causes leg pain, numbness, or weakness that improves with sitting or rest. Previous treatments, including physical therapy, injections, or surgery, are also important parts of the picture.

These details can help you and your doctor have a more informed conversation about which treatment options may be appropriate, including decompression, fusion, or TOPS.

Walking tolerance
Some patients notice they can walk farther when leaning on a cart, and less far when standing upright.
Prior treatments
Physical therapy, medicines, injections, and previous surgery all belong in a candidacy discussion with a clinician.
Goals of care
Walking farther, reducing pain, and avoiding another operation are different goals. A good consult makes those trade-offs explicit.

Questions

Frequently asked questions

What is this website?

Spine Motion Guide is an independent patient education publication. It explains lumbar spinal stenosis surgery in plain language: decompression, fusion, and TOPS as one motion-preserving option with FDA-reviewed evidence in a defined group of patients.

Is this medical advice?

No. Nothing here diagnoses a condition, clears anyone for surgery, or replaces a conversation with a licensed clinician who can review your history and imaging.

Is this an official Premia Spine site?

No. This publication is not owned, funded, or sponsored by Premia Spine, is not affiliated with the company, and does not send patient leads to it. Independence and sourcing rules are stated on this site without manufacturer sponsorship.

What is TOPS in this context?

TOPS is a posterior lumbar implant placed after decompression. It is meant to stabilize a treated level without a rigid fusion. FDA approved it in 2023 for a specific indication. The study results, safety findings, and limits are on the clinical evidence page.

How should I use the candidacy page?

Use the candidacy questionnaire to organize symptoms, imaging, prior treatments, and questions before a visit. It does not determine whether any procedure is appropriate.
