Promising Trial Results Released for Neo Medical’s Force Control Tech in Spinal Fusion

Neo Medical is touting positive post-market clinical study data that shows the significant benefits of its Force Control Technology in spinal (thoracolumbar) fusion procedures.

Jointly led by Prof. David Noriega, chief of the Orthopaedic Department at Hospital Clínico Universitario de Valladolid (Spain), and Dr. Yasser Abdalla, head of the Department of Neurosurgery, Nordwest-Krankenhaus, Sanderbusch(Germany), the study highlights the clear advantages of Neo Medical’s platform in reducing early screw loosening and improving patient outcomes by managing unintended mechanical stress during surgery. The data was published in World Neurosurgery.¹

“Limiting unintended stress during thoracolumbar fusion surgery is essential to reducing complications like screw loosening and implant failure,” Noriega said. “Optimizing the fixation process with Neo Medical’s Force Control Technology supports real improvements in clinical outcomes and patients’ quality of life.” 

The clinical study involved 75 patients undergoing thoracolumbar fusion surgery to treat conditions including trauma, spinal stenosis, and degenerative disc disease.

The data showed a significant reduction in screw loosening, with the Neo Pedicle Screw System (PSS) demonstrating a 2.7% screw loosening rate after one year—3.4 times lower than the 9.2% rate seen in the control group. Neo’s IP protected Force Control Technology was responsible for this result, delivering powerful correction while limiting the unintended stress applied to both the implants and surrounding anatomical structures.²

“These results highlight how Neo Medical’s Force Control Technology allows us to apply corrective forces effectively while minimizing harmful mechanical stress,” Dr. Abdalla stated. “By protecting both the implants and the patient’s anatomy, we can reduce complications and achieve better outcomes in spinal fusion surgery.”

The study also demonstrated substantial improvements in patients’ postoperative daily function. A year after surgery, patients treated with Neo Medical’s technology reported disability scores 38% lower than those in the control group, indicating better daily function (Oswestry Disability Index scores of 22.6 and 36.6, respectively).

At the two-year follow-up, the ODI score dropped to 19, with significant reductions in back pain, from a baseline visual analog scale score of 80.3 to 21.6 at one year. The implant-related revision rate in the Neo Medical group was 4.1%, representing a 58% reduction compared to published data (9.8%).

“The results of this study highlight the clinical value of our Force Control Technology in reducing some of the most common and damaging complications that too often limit the benefits patients see after surgery. Our goal is to move spine surgery beyond the limits of legacy systems, reimagining treatment processes to make them safer, more efficient, and more effective for every patient,” Neo Medical Co-Founder/CEO Vincent Lefauconnier commented.

Neo Medical is a Swiss technology company that is advancing spine care by enhancing surgical precision, improving patient outcomes, and elevating processes both inside and outside the operating room. The company integrates cutting-edge technologies and materials with data-driven solutions to address key challenges in the field.

Neo Medical’s proprietary platform combines intraoperative augmented reality, artificial intelligence-driven data guidance, and unique Force Control Technology, designed to enable surgeons to optimize treatments and reduce complications. This seamless integration is intended to provide a personalized and effective approach to spine surgery, which enhances patient care and surgical efficiency.

Alongside its technology portfolio, the company’s operational service model—”SmartService”—streamlines administrative processes before, during, and after surgery, and is intended to improve efficiency, reduce treatment-associated costs, and contribute to a more sustainable healthcare system. Headquartered near Lausanne, Switzerland, Neo Medical is expanding its global presence, with operations in the United States, Spain, France, and Germany.
