Lumbar Operatively Inserted PerQdisc Artificial Implant Following Nuclectomy 3

Inclusion Criteria: * Patient is skeletally mature and at least 21 years of age. * Patient has a lumbar disc herniation, between L1-S1, with compressive radiculopathy of the traversing nerve root requiring partial discectomy or sequestrectomy. Only one lumbar disc may be treated with the PerQdisc device. * Patient must have an overall disc herniation (extrusion or protrusion) such that half or less of the width of the dorsal annulus of the spinal canal, is affected by the herniation. The width of the canal is defined by the lateral recesses and the central canal (i.e. pedicle to pedicle). * Patient must have a minimum of 6 mm of disc height as measured in the center of the affected disc. * Patient is willing and able to give informed consent. * All surgeries must be approved by at least 2 members of the Medical Advisory Board (MAB) - potential anatomical limitations of safely accessing Kambin's, extent of annular disruption, as well as overall patient criteria will be evaluated Exclusion Criteria: * Patient has had prior lumbar spine surgery at the index level (nucleoplasy is acceptable). * Patient has had spinal fusion in the lumbar spine. Cervical or thoracic fusion is allowed as long as there are no neurologic deficits in the lower extremities. * Patient has spondyloarthropathy or other spondylolisthesis greater than 4 mm or spondylolysis at the index level (on standing X-ray). * Patient has underlying moderate or severe spinal stenosis (congenital, degenerative, or due…
