Posterior lumbar interbody fusion with a single Valeo OL ceramic cage.
- Roland Morris Disability Questionnaire (RMDQ) [ Time Frame: 12 months post-op ]The improvement in the RMDQ over the pre-op RMDQ value for each group will be compared
- Fusion status [ Time Frame: 3 mo., 6 mo., 12 mo., 24 months ]Plane film radiographs will be used to assess fusion at all four follow-up periods. At 12 months a CT scan will be performed.
- Oswestry Disability Index (ODI) [ Time Frame: 12 months post-op ]The improvement in the ODI over the pre-op ODI for each Group
