Brief Summary
Compare the lumbar fusion rates at 12 and 24 months when lumbar arthrodesis is performed using Virtuos or Autograft Bone Graft. Surgical approach is limited to TLIF (MIS or Open) with posterior fixation and supplemental posterolateral fusion as directed by physician, but must comply with FDA approved/cleared indication for use and labeling.

Eligibility Criteria
You may qualify if:
- At least 18 years of age at the time of surgery
- Undergoing lumbar spine fusion surgery with one of the following bone grafting options:
- Virtuos
- Virtuos with Autograft (local bone)
- Autograft
- Autograft + allograft (cancellous bone chips)
- Subject must have a documented diagnosis of DDD. DDD is defined by back and/or radicular pain with degeneration of the disc as confirmed by medical history, physical examination, and radiographic studies that may include CT, MRI, plain X-ray film, discography, myelography, etc. with one or more of the following findings:
- Instability as defined by \>3mm translation or \>5 degrees angulation
- Osteophyte formation of facet joints or vertebral endplates
- Decreased disc height, on average by \>2mm, but dependent upon the spinal level
- Scarring/thickening of ligamentum flavum, annulus fibrosis, or facet joint capsule
- Herniated nucleus pulposus
- Facet joint degeneration/changes; and/or
- Vacuum phenomenon
- Subject may have up to a Grade I Spondylolisthesis of the lumbar spine with clinical manifestations of one or more of the following phenomena:
- +10 more criteria
You may not qualify if:
- Subject is under 18 years of age (\<18) at the time of consent
- Subject has had prior lumbar spine fusion surgery at any level
- Subject has greater than grade 1 spondylolisthesis of the lumbar spine
- Subject is currently undergoing treatment for malignancy or has undergone treatment for malignancy in the past 5 years (benign skin cancer is permitted)
- Subject is pregnant (confirmed by pregnancy test) or nursing or planning to become pregnant during the two years (24 months) following arthrodesis
- Subject has an active local or systemic infection or is undergoing adjunctive treatment for local or systemic infection
