Study of the PerQdisc Nucleus Replacement Device for Degenerative Disc Disease in Adults Aged 22 to 70

What this Trial Is About

Researchers are evaluating the safety and effectiveness of the PerQdisc Nucleus Replacement Device NRD for patients with degenerative disc disease DDD causing chronic low back pain. This prospective, open-label, multi-center study involves 72 patients who have DDD in one or more lumbar discs between L1 and S1. The study aims to collect additional data on this minimally invasive device, which is designed to maintain disc height and preserve spinal motion compared to the current standard spinal fusion surgery. Participants will undergo nucleus replacement surgery using the PerQdisc device via standard anterior, lateral, or minimally invasive posterolateral surgical approaches to replace the single nucleus pulposus in the affected lumbar disc. All surgeries require approval from a Medical Advisory Board. The study focuses on patients who have exhausted at least six months of conservative treatments for their back pain and meet specific criteria, including disc height and pain scores. During the study, participants will be monitored closely with evaluations at multiple time points up to five years. Researchers will assess performance outcomes such as disability Oswestry Disability Index, pain levels Visual Analog Scale, disc height, and range of motion, as well as safety outcomes including device expulsion, failure, neurological status, revision surgeries, and serious adverse events. Follow-up visits will include questionnaires, imaging, and clinical assessments to track the devices impact over time.
