Dr. Paul’s approach to spine surgery is centered on a simple principle: achieve a durable, lasting result while minimizing disruption to the body. For many patients requiring lumbar fusion, that philosophy is reflected in the use of Minimally Invasive Transforaminal Lumbar Interbody Fusion (MIS-TLIF). In fact, Dr. Paul performs predominantly minimally invasive lumbar fusions in his practice, most commonly utilizing MIS-TLIF as a reliable, muscle-sparing technique for appropriately selected patients.
Dr. Ronjon Paul was an early adopter of these techniques in the early 2000s, during the formative years of modern minimally invasive spine surgery. Over the past two decades, he has refined these methods alongside the evolution of the technology itself, helping bring what was once considered novel into today’s standard of care.
Traditional open lumbar fusion relies on wide exposure of the spine, which requires detaching the paraspinal muscles from their natural attachments. While effective, this approach can contribute to postoperative pain, blood loss, and a longer recovery.
MIS-TLIF uses a different pathway. Through small incisions, specialized instruments and tubular retractors allow access to the spine by gently separating muscle fibers rather than detaching them. This “muscle-splitting” technique preserves normal anatomy while still allowing for a complete decompression and stabilization.
This concept was first clearly demonstrated in the landmark work by Kevin T. Foley, which showed that minimally invasive lumbar fusion significantly reduces soft-tissue injury compared to open approaches (Foley et al., 2003).
Over the last two decades, a consistent body of peer-reviewed evidence has evaluated MIS-TLIF against traditional open fusion. The findings are remarkably consistent.
Patients undergoing MIS-TLIF tend to experience:
A large prospective comparative study by Stefan Hartmann and colleagues confirmed that while minimally invasive techniques offer meaningful short-term recovery advantages, long-term clinical outcomes are equivalent to open fusion (Hartmann et al., 2022).
In other words, the destination is the same, but the journey is often easier.
Importantly, modern studies continue to show that MIS-TLIF achieves:
Recent analyses, including studies published through 2026, reinforce that when performed by experienced surgeons, minimally invasive approaches maintain the same durability as traditional techniques while improving the early recovery experience.
Minimally invasive spine surgery is technically demanding. The benefits seen in the literature depend heavily on surgical expertise, careful patient selection, and familiarity with advanced instrumentation.
Dr. Paul’s experience reflects this depth:
Representative external recognition and media:
This combination of experience, recognition, and technical precision is essential to safely delivering the advantages described in the research.
For patients, the distinction is often felt in the recovery process. By preserving muscle and minimizing surgical disruption, MIS-TLIF can allow for:
At the same time, not every condition is best treated with a minimally invasive approach. Surgical planning remains individualized, with the goal of selecting the technique that provides the safest and most reliable outcome for each patient.

Both approaches achieve similar long-term outcomes. Minimally invasive TLIF is designed to reduce tissue disruption, which often leads to less pain, shorter hospital stays, and a faster early recovery.
Candidates typically include patients with conditions such as degenerative spondylolisthesis, spinal stenosis with instability, or recurrent disc herniation. The decision depends on your anatomy, symptoms, and prior treatments.
Many patients are up and walking the same day or the next day after surgery. Most return to light activities within a few weeks, with continued improvement over several months as the fusion heals.
No. The primary benefit is preservation of muscle and soft tissue, not just incision size. This is what drives improved recovery.
Yes. Multiple studies show similar fusion rates and long-term outcomes between MIS-TLIF and open fusion when performed appropriately.
Risks include infection, nerve injury, nonunion (failure of fusion), and hardware-related complications. These risks are similar to open surgery, though some perioperative risks may be lower with minimally invasive techniques.
MIS-TLIF is technically demanding. Outcomes are closely tied to surgeon experience, case volume, and familiarity with the technique and technology.
Dr. Paul has over two decades of experience performing minimally invasive lumbar fusions and was an early adopter of MIS-TLIF techniques in the early 2000s. He performs predominantly minimally invasive lumbar fusions in his practice, with a focus on muscle-sparing approaches. He has trained surgeons in these techniques both nationally and internationally and has been repeatedly recognized as a Castle Connolly Top Doctor. He has also been featured in national spine media, including Becker’s Spine Review, reflecting peer recognition of his expertise in minimally invasive and complex spine care.
