Eligibility Criteria
Inclusion Criteria:
- Subject is skeletally mature

Degenerative Disc Disease (DDD) at one level or two contiguous levels from L2 to S1

Exclusion Criteria:
- Subject is obese (BMI > 40)
- Subject is sensitive to titanium materials
- Subject has an active infection at the operative site
- Subject has marked local inflammation
- Subject has any abnormality present which affects the normal process of bone remodeling including, but not limited to, severe osteoporosis involving the spine, bone absorption, osteopenia, tumors involving the spine, active infection at the site, or certain metabolic disorders affecting osteogenesis
- Subject has any mental, trauma, or neuromuscular disorder which would create an unacceptable risk of fixation failure or complications in postoperative care
- Subject has any open wounds
- Subject is pregnant or plans to become pregnant during the course of the study
- Subject has inadequate tissue coverage over the operative site.
- Subject has an neuromuscular deficit which places an unsafe load on the device during the healing period
- Subject has any condition of senility, mental illness, or substance abuse
- Subject has any other medical or surgical condition which would preclude the potential benefit of spinal implant surgery, such as the presence of tumors, congenital abnormalities, elevation of sedimentation rate unexplained by other diseases, elevation of white blood cell count (WBC), or marked left shift in the WBC differential count.

Outcomes
Primary Outcome Measures
Number of Participants With Fusion Success
CT and X-ray imaging will be obtained at study visits and Fusion Success will be defined by the following criteria: no lucent area around the implant; no presences of herniated disk, central stenosis, lateral recess stenosis, foraminal stenosis, facet anthropathy; no fracture of the device, graft or vertebra; visible bone formation in or about the graft material; less than 3 degrees of inter-segmental position change on flexion and extension views; presence of subsidence: a migration of more than 3mm into the adjacent vertebra; and the proportion of bridging bone visually estimated over the surface area of the joint
Secondary Outcome Measures
Change in Visual Analogue Scale
Change in low back pain as indicated by Visual Analogue Scale (VAS). The VAS measures subjects' self-reported pain level on a 100 mm line on which the subject indicates their level of pain, where 0 is no pain and 100 is worst imaginable pain.
Change in Low Back Function
Change in Oswestry Disability Index (ODI) score. The ODI assesses disability related to lower back pain using a Likert 0 to 5 scale. There are 10 sections to the assessment, and the scores are represented as a percentage ranging from 0 (no disability) to 100 (completely disabled).
Change in Quality of Life: SF-36 PCS
Change in perception of quality of life, as measured by Short Form 36 Health Survey (SF-36 PCS). The SF-36 PCS is a 36-item patient reported health questionnaire to measure perceived quality of life across 8 domains. Higher scores indicate higher quality of life, and lower scores indicate lower quality of life. Scores range from 5 (poor physical function) to 80 (excellent clinical function).
Number of Participants That Return to Work
Subjects who were unable to work due to their back pain who return to work.
Ambulatory Status
Amount of time to full ambulation without assistance for study participants who had no or partial ambulation at baseline.
Number of Participants With Serious Adverse Events
Any event meeting the Serious Adverse Event reporting criteria detailed in the study protocol occurring at the following time intervals: TLIF procedure, hospital recovery and discharge, and 6 weeks-, 3 months-, 6 months- and 12 months post operation
Change in Quality of Life: EQ-5d
Change in perception of quality of life, as measured by the EuroQol-5d (EQ-5d). The EuroQol-5d is a five question broad quality of life measure that can be combined into a single index and represents current health. A score of 0.0 is the worst imaginable health while a score of 1.0 would be the best imaginable health.

5. Study Description
Brief Summary
The purpose of this study is to compare outcomes of patients with degenerative disc disease undergo lumbar spinal fusion with Stryker's Tritanium® Posterior Lumbar Cage or the UniLIF PEEK implant.
Detailed Description
This study protocol intends to examine the difference in efficacy between the Tritanium Posterior Lumbar Cage and the UniLIF PEEK implant with respect to how long it takes to achieve fusion of the spine. Study participants will undergo a transforaminal lumbar interbody fusion (TLIF) surgery and return for CT and x-ray follow-up to measure the degree to which fusion has been achieved. Survey methodology to assess perceived pain, level of disability, and quality of life will also be used to measure the differences between groups on these components.
