✓. Has degenerative disc disease as noted by back pain of discogenic origin, with or without leg pain, with degeneration of the disc confirmed by patient history (e.g., pain \[leg, back, or symptoms in the sciatic nerve distribution\], function deficit and/or neurological deficit) and radiographic studies (e.g., CT, MRI, X-Ray, etc.) to include one or more of the following:
✓. Has preoperative Oswestry score \>= 35.
✓. Has no greater than Grade 1 spondylolisthesis utilizing Meyerding's Classification (Meyerding HW, 1932.).
✓. Has single-level symptomatic degenerative involvement from L2 to S1.
✓. Is at least 18 years of age, inclusive, at the time of surgery.
✓. Has not responded to non-operative treatment (e.g., bed rest, physical therapy, medications, spinal injections, manipulation, and/or TENS) for a period of at least 6 months.
✓. If female of child-bearing potential, who is not pregnant or nursing, and who agrees to use adequate contraception for 16 weeks following surgery.
✓. Is willing and able to comply with the study plan and sign the Patient Informed Consent Form.

✕. Had previous anterior spinal fusion surgical procedure at the involved level.
✕. Has posterior spinal instrumentation (which will not be removed) stabilizing the involved level or has had a previous posterior lumbar interbody fusion procedure at the involved level.
✕. Has a condition which requires postoperative medications that interfere with fusion, such as steroids.
✕. Has been previously diagnosed with osteopenia, osteoporosis, or osteomalacia to a degree that spinal instrumentation would be contraindicated.
✕. Has presence of active malignancy.
✕. Has overt or active bacterial infection, either local or systemic.
✕. Is grossly obese, i.e., weight\> 40% over ideal for their age and height.
✕. Has fever (temperature\> 101°F oral) at the time of surgery.
