Introduction: We have already reported percutaneous lumbar interbody fusion (PELIF) that can be performed percutaneously and safely by using an L-shaped retractor etc. We report clinical results over one year after surgery.Methods: PELIF with hybrid facet screwing or conventional percutaneous pedicle screwing was used for severe intervertebral disc degeneration and spondylolisthesis, and also at L5-S1 level.Results: The subjects consisted of 16 cases; hybrid facet screw fixation was performed in 9, L5/S1 bilateral transfacet pedicle screw fixation in 2, and pedicle screw fixation in 5 cases. Severe intervertebral disc degeneration was performed in 14, spinal stenosis in 5, foraminal stenosis in 5, spondylolisthesis in 4 cases (with duplication). The mean VAS score (0-10) for low back pain was decreased from preoperative 6.4 to 1.9, and for leg symptoms was decreased from preoperative 4.9 to 1.1. No cage-insertion-related complications were detected.Conclusion: PELIF is a possible therapeutic option that should be considered for not only spondylolisthesis at various intervertebral levels but also for severe disk degeneration because of its minimal invasiveness.
