Clinical Trials

Nucleus 161 

Feasibility Study for a Lumbar Spine Disc Nucleus Replacement (PerQdisc).  

N161 was a clinical trial to study the feasibility of implanting the PerQdisc device in the lumbar spine of patients suffering from chronic low back pain. Patients are assessed for pain and disability using standardized patient reported outcome measures as well as X-ray and MRI imaging.

LOPAIN3 

Safety Study for a Lumbar Spine Disc Nucleus Replacement (PerQdisc). 

LOPAIN3 is a clinical trial designed to gather clinical data on the feasibility, safety, and efficacy of performing the PerQdisc procedure concurrently following successful discectomy, using a minimally invasive posterolateral (MIPL) approach in patients presenting with symptomatic radiculopathy from a focal lumbar disc herniation that requires surgical decompression .. Patients are assessed for pain and disability using standardized patient reported outcome measures as well as X-ray and MRI imaging. (Click here for more information)
