Centinel Spine, LLC, a leading global medical device company addressing cervical and lumbar spinal disease through anterior surgical access, announced findings of a new study to be presented during the North American Spine Society (NASS) 37th Annual Meeting on Thursday, October 13, 2022. Thierry Marnay, MD will present results from the study that support long-term mobility superiority of Centinel Spine’s prodisc L Lumbar Total Disc Replacement (TDR) device compared to two-level hybrid reconstruction.

The study expands the evidence validating the clinical efficacy of prodisc L and is one of the first long-term mobility comparisons between two-level lumbar TDR and hybrid constructs consisting of one-level lumbar TDR combined with one-level anterior lumbar interbody fusion (ALIF). A total of 235 patients who underwent lumbar surgery from 2003 to 2013 were followed—consisting of 170 patients receiving L4-S1 two-level lumbar TDR and 65 patients receiving L5-S1 fusion and L4-L5 TDR hybrid construct.
According to the study, after a minimum of 24 months follow-up, the two-level prodisc L TDR demonstrates superiority in absolute lumbar mobility and pelvic motion. The hybrid construct demonstrates an overall lack of compensation in lumbar mobility and pelvic motion as compared to the two-level lumbar TDR. Although measures of activity and pain were equivalent between the study groups, the two-level TDR also demonstrated functional superiority versus the hybrid construct (Marnay, Thierry. “Mobility Parameters in Two-Level Lumbar TDR vs Hybrid Construct: Clinical Results in 235 Patients”, NASS 2022 Annual Meeting, Thursday, October 13, 2022, Chicago, Illinois).
Centinel Spine‘s CEO, Steve Murray, stated, “This study further reinforces the long-term effectiveness of the prodisc system, a proven technology that supports the advancement of patient care. The system was engineered with proven design principles, and this is another study that demonstrates continued positive results of prodisc L after over 30 years of clinical use.”
The prodisc L Lumbar TDR system, along with the newly-approved prodisc cervical TDR portfolio that allows the disc to be matched to patient anatomy, will be featured at the Centinel Spine booth (#4224) during NASS 2022.
