This study evaluated the safety and effectiveness of ProDisc-L lumbar total disc replacement compared to circumferential spinal fusion for treating discogenic pain at one vertebral level (L3 to S1). Conducted as a prospective, randomized multicenter trial regulated by the FDA, it involved 286 patients assessed pre- and post-surgery at multiple intervals (6 weeks to 24 months). Results indicate that ProDisc-L is both safe and efficacious, demonstrating superiority over circumferential fusion based on various clinical criteria.

Presentation Transcript

  1. Results of the Prospective, Randomized, MulticenterFDA Investigational DeviceExemption Study of the ProDisc-L Total DiscReplacement Versus Circumferential Fusion for theTreatment of 1-Level Degenerative Disc Disease

  2. Study Design A prospective, randomized, multicenter, Food and Drug Administration-regulated Investigational Device Exemption clinical trial.

  3. Objective • To evaluate the safety and effectiveness of the ProDisc-L lumbar total disc replacement compared to circumferential spinal fusion for the treatment of discogenic pain at 1 vertebral level between L3 and S1.

  4. Background Data • As part of the Investigational Device Exemption clinical trial, favourable single centre results of lumbar total disc replacement with the ProDisc-L have been reported previously.

  5. Methods • 286 patients were treated. Patients were evaluated before and after surgery, at 6 weeks, 3, 6, 12, 18, and 24 months. Evaluation at each visit included patient self-assessments, physical and neurologic examinations, and radiographic evaluation.

  6. Conclusions • ProDisc-L has been found to be safe and efficacious. In properly chosen patients, ProDisc-L has been shown to be superior to circumferential fusion by multiple clinical criteria.
