WEST CHESTER, PA — Centinel Spine®, LLC has announced the findings of a landmark study validating the long-term clinical success of its prodisc L Lumbar Total Disc Replacement (LTDR) technology. Published by The Journal of Bone & Joint Surgery, the research highlights the durability and effectiveness of the device in treating lumbar degenerative disc disease (DDD).
The study analyzed outcomes from 1,187 patients who underwent 1- or 2-level LTDR procedures between 1999 and 2013 at Montpellier Spine Institute in France. Patients were followed for an average of nearly 12 years, with some tracked for up to 21 years. The results demonstrated an exceptionally low revision rate of 0.67% and a 1.85% rate of adjacent-level surgery, confirming the system’s ability to preserve spinal mobility and reduce the risk of further surgeries.
Outcomes were consistent regardless of whether patients underwent 1- or 2-level LTDR or had prior discectomy surgeries, showcasing the versatility of prodisc L across a broad patient spectrum.
“Total disc replacement, and especially the prodisc technology, is a concept we started to develop in the 1980s,” said Dr. Thierry Marnay, inventor of prodisc. “The quality and robustness of this study’s results fundamentally confirm the long-term efficiency and safety of LTDR. There is a direct link between restored, pain-free mobility and improved quality of life.”
With more than 125,000 prodisc L devices implanted worldwide and nearly 35 years of clinical use, the technology continues to serve as a proven motion-preserving alternative to fusion. The system is FDA-approved for one-level, two-level, and Anatomic Endplate™ indications, further solidifying its position as a leader in spine care innovation.
