This retrospective study expands the evidence validating the fixed-core design of the prodisc L device and includes 1,187 patients that underwent LTDR surgery for chronic lumbar degenerative disc disease (DDD), making it one of the largest LTDR patient cohorts ever evaluated.
The study was also one of the first of its kind to evaluate LTDR patients across such a long duration of follow-up—7 to 21 years (mean of 11 years and 8 months). The goal of the study was to evaluate the clinical outcomes of patients who underwent 1- or 2-level LTDR, as well as to evaluate patients with or without prior discectomy at the index level(s).
The study covered all eligible LTDR procedures performed at a single institution (Montpellier Spine Institute (CCV) Clinique du Parc, Castelnau-le-Lez, France) from 1999 to 2013, and included 772 patients that underwent a 1-level LTDR procedure and 415 that underwent a 2-level procedure. A total of 373 of the patients had prior discectomy surgery.
The long-term results of the study found:
“This study was conducted with the clinical team in Clinique du Parc Montpellier over the last 25 years, and ultimately published in one of the most prestigious scientific journals. The quality and the robustness of its results are a major achievement that fundamentally confirms the long-term efficiency and safety of LTDR through an anterior approach and the positive clinical results for patients after surgery with prodisc L. It is no longer possible to ignore the fundamental positive outcomes through the preservation and/or restoration of spine mobility.”
