Is Endoscopic Spine Surgery Really Worth the Cost? Our New Research Has an Answer

Posted on: July 8th, 2026 by Our Team

Patients researching spine surgery today are asking a sharper question than they used to: not just “which surgery is right for me,” but “which approach makes the most sense financially, too.” As endoscopic and minimally invasive techniques have matured, that’s a fair question — and one we set out to answer with real cost data rather than assumptions.

In our new study, published in Clinical Spine Surgery, our team compared the actual costs of four surgical approaches to lumbar disc herniation: uniportal endoscopic surgery, biportal endoscopic surgery (UBE), tubular (microscopic) surgery, and traditional open surgery.

Why we looked at this

Most conversations about surgical cost stop at “outpatient is cheaper than inpatient.” That’s true, but incomplete — it doesn’t capture differences in operating room time, disposable equipment, or the setting where surgery happens. We analyzed 195 single-level lumbar discectomies performed by two spine surgeons across five different care settings — an academic hospital, a private hospital, and three outpatient surgical centers — to get a real-world, apples-to-apples cost picture in the U.S. healthcare system, where this kind of direct comparison had not been done before.

What we found

Using tubular (microscopic) surgery as the baseline, uniportal endoscopic surgery was the most expensive technique overall — roughly two and a half times the cost of tubular surgery. That difference came down almost entirely to equipment: uniportal systems require specialized, largely disposable tools (including a dedicated burr and radiofrequency wand) that drove supply costs up to roughly 85% of the total cost per case in some settings.

Biportal endoscopic surgery (UBE), by contrast, ran only moderately higher than tubular surgery — about 14% to 60% more, averaging roughly 23% higher — because it uses standard arthroscopic equipment most hospitals and surgical centers already own. Open surgery landed close to tubular surgery as well, only slightly higher on average. These relative differences held steady whether the surgery was performed in a hospital or an outpatient surgical center.

What this means if you’re considering spine surgery

• Not all “minimally invasive” or “endoscopic” surgery carries the same cost profile. Uniportal and biportal endoscopic techniques are often discussed interchangeably, but our data shows they are financially very different procedures — which is exactly why we studied them separately instead of grouping them together.
• Biportal endoscopic surgery stood out as the most cost-efficient endoscopic option in this analysis, while offering the same core benefits patients want from endoscopic surgery: smaller incisions, preserved muscle and tissue, and a faster path back to normal activity.
• The right technique still depends on your specific anatomy and diagnosis. Cost is one input into that decision — not a substitute for a surgeon’s evaluation of what your spine actually needs.

Why we’re sharing this

This kind of cost analysis has been studied abroad, but rarely within the U.S. healthcare system — where cost structures, reimbursement, and facility types vary enormously. Dr. Singh has spent much of his career building the evidence base for minimally invasive and endoscopic spine surgery, including as an editor of the recently published Textbook of Endoscopic Spine Surgery. Research like this is part of how our practice decides which techniques to offer patients, and why our outpatient program is built around approaches with real outcomes and cost data behind them — not simply the newest available technology.

FAQ

Is biportal endoscopic surgery cheaper than open spine surgery?

Not necessarily lower than open surgery on a per-case basis, but our data found it moderately priced overall — well below uniportal endoscopic surgery — while offering similar minimally invasive benefits.

Why is uniportal endoscopic surgery more expensive than biportal?

Largely because of specialized, mostly single-use equipment that biportal techniques don’t require, since biportal surgery uses standard arthroscopic tools most facilities already have.

Does a lower-cost technique mean it’s the right choice for me?

No — cost is one factor. The right approach depends on your specific diagnosis, anatomy, and surgical history, which is determined during a surgical evaluation.
