What is the Optimum Fusion Technique for Adult Isthmic Spondylolisthesis—PLIF or PLF? A Long-Term Prospective Cohort Comparison Study

Abstract

This study strongly supports the use of PLIF to obtain equivalent or superior clinical outcomes compared with PLF for spinal fusion for lumbar IS. Although there are considerable issues when commenting on the results of observational studies, the results of this study are the first to report long-term follow-up beyond 2 years, and further larger long-term randomized studies are suggested.
