The no-fusion promise, and the conditions where we mean it

What the promise actually says

For the conditions Synergy treats — single-level or limited multi-level disc herniations, focal stenosis, foraminal narrowing, facet-mediated pain, SI joint pain — fusion is rarely the correct first-line surgical answer. Our promise: we won’t recommend fusion when a smaller procedure can address the problem.

This is a substantive promise, not a slogan. It means: if you arrive having been told fusion is the only option, and your imaging and clinical picture show a condition addressable by decompression alone, we’ll tell you that. We’ll explain why decompression is appropriate and what the comparison looks like.

Why fusion got over-prescribed

Fusion rates for degenerative spine conditions increased substantially over recent decades. The reasons cluster: reimbursement structures rewarded fusion procedures more than simpler alternatives; surgical training emphasized fusion techniques; instrumentation manufacturers heavily marketed fusion implants; and patient expectations followed surgical fashion.

Some of that growth was justified — fusion is genuinely the right answer for specific indications like significant instability, deformity correction, or selected revision situations. But a substantial portion was probably over-treatment: fusion for indications where decompression alone would have sufficed. The literature on this is uncomfortable to read but the pattern is real.

Where fusion is genuinely appropriate

The promise has limits. Fusion is the appropriate procedure in several situations: significant spondylolisthesis with instability, isthmic spondylolisthesis with progressive slip, congenital or developmental deformity requiring correction, fracture or trauma requiring stabilization, and certain revision situations where prior decompression has destabilized a segment.

We don’t perform fusion ourselves. Patients with conditions genuinely requiring fusion are referred to colleagues we trust to perform it well. The promise isn’t “we’ll never tell you fusion is needed” — it’s “we won’t recommend it when something less is sufficient.”

How to evaluate a fusion recommendation

If fusion has been recommended for you, several questions are worth asking. What specific anatomical finding justifies fusion vs decompression alone? Is there demonstrated instability on flexion-extension imaging, or is the recommendation based on degenerative changes that decompression could address? Has decompression-only been considered? What’s the recommending surgeon’s experience with non-fusion alternatives for similar cases?

The answers to these questions distinguish surgical recommendations that are evidence-based from those reflecting a surgeon’s procedure mix. Second opinions from surgeons who perform both fusion and non-fusion options often clarify the picture. Our free MRI review is one path to that second opinion.

What we tell patients who do need fusion

Patients whose imaging and clinical picture genuinely warrant fusion are told that directly. We explain why fusion is appropriate for their specific situation, what the recovery looks like, and we refer to surgeons we trust to perform it. The honesty is the point.

The opposite framing — pretending every patient is a candidate for decompression alone — would itself be over-promising. The no-fusion promise is meaningful precisely because it acknowledges where fusion is genuinely necessary.

What the promise says — and what it doesn’t

The no-fusion promise has a specific scope: at Synergy, we don’t perform fusion procedures and we don’t recommend them for conditions where decompression alone would address the pathology. The promise is not “fusion is always wrong” — that would be inaccurate. Fusion is correct for patients with significant spinal instability, severe spondylolisthesis beyond a threshold, scoliosis-related curve progression, or significant deformity. For those patients, our practice provides referral guidance to qualified fusion surgeons rather than attempting procedures we don’t perform. The candor matters — see /our-philosophy/ for context.

Why this matters — the irreversibility problem

Spinal fusion is functionally irreversible. Once vertebrae are fused, the patient cannot return to an unfused state, and adjacent-segment disease (new pathology at levels adjacent to the fused segment) is a documented long-term risk. The clinical question patients should ask before fusion is not just “will this help my current symptoms?” but “what does my spine look like in 10 years?” Adjacent-segment disease literature is searchable at PubMed; patient-facing summary at Cleveland Clinic.

When we refer patients out for fusion

Some patients arriving at Synergy genuinely need fusion. When imaging confirms spondylolisthesis with instability beyond what decompression can address, scoliotic curve progression is documented, or prior surgery has created instability requiring correction, fusion is the appropriate recommendation — and we say so. The free MRI review identifies these patients before any travel commitment. Referrals typically point to fusion surgeons known to us through professional relationships with NASS. Telling patients they need fusion when they do is what makes the no-fusion-first orientation credible rather than ideological.

The data behind the promise

The clinical foundation is empirical: a significant share of patients told they need fusion for conditions like single-level lumbar stenosis or herniated disc with radiculopathy can be successfully treated with decompression alone. The Cochrane Library systematic reviews on lumbar stenosis treatment consistently distinguish these cases. Our evidence page summarizes the most relevant studies. Procedural alternatives: endoscopic decompression and endoscopic discectomy.

The specific clinical scenarios where fusion is (and isn’t) needed

Fusion is genuinely indicated in several clinical scenarios and the practice does not dispute this. Spondylolisthesis with instability — vertebrae that slip beyond a threshold under normal loading — typically requires fusion because decompression alone doesn’t address the underlying instability, and post-decompression instability progression is a real risk. Scoliosis with curve progression — adult degenerative scoliosis with documented curve progression on serial imaging — often requires fusion to prevent further progression, particularly when the curve is generating neurological symptoms. Post-traumatic instability — vertebrae destabilized by fracture, ligamentous injury, or prior surgical dissection — requires fusion to restore stability. Tumor resection requiring extensive bone removal typically requires fusion for stabilization.

The scenarios where fusion is more debatable are the ones the practice’s philosophy specifically addresses. Single-level lumbar stenosis — a common condition producing neurogenic claudication and radicular symptoms — is treatable with targeted decompression in most cases. Fusion is not required unless there’s associated instability. Single-level herniated disc with radiculopathy — the classic sciatica pattern — is treatable with discectomy alone; fusion adds no additional benefit for the discectomy indication in most cases. Facet arthritis with axial back pain — often treated with fusion elsewhere — can frequently be addressed with facet rhizotomy (radiofrequency ablation) rather than fusion. Foraminal stenosis with unilateral radiculopathy is treatable with targeted foraminotomy without fusion.

The clinical judgment about whether a specific case needs fusion or decompression comes down to imaging findings, symptom pattern, and physical examination — not to the reflexive preference of the evaluating surgeon. When patients receive a fusion recommendation elsewhere and want an independent assessment, the free MRI review provides exactly that: Dr. McMillan reviews the imaging and provides a candid assessment of whether the case genuinely requires fusion or whether decompression alone would address the pathology. Cases that genuinely require fusion get referred to qualified fusion surgeons; cases where decompression is appropriate get scheduled at Synergy. The referral network is a natural byproduct of the honesty policy.

The second opinion framework covers the process for patients seeking an independent assessment after a fusion recommendation elsewhere. It’s the most common pathway into the practice for out-of-town patients — and it’s the pathway that makes the no-fusion promise practically meaningful rather than just an ideological stance.
