Comparative effectiveness of oblique lumbar interbody fusion with anterior screw fixation versus percutaneous pedicle screw fixation for treating lumbar degenerative diseases: A systematic review and meta-analysis.

While OLIF-AF displayed favorable results in intraoperative parameters, such as reduced blood loss and shorter operative times, it did not significantly differ in patient-reported outcomes and radiographic assessments compared to OLIF-PF. Interpretation of findings must consider limitations in sample sizes and study heterogeneity. Future investigations with larger, more diverse cohorts and extended follow-ups are imperative to confirm these preliminary findings and comprehend the actual clinical impact of these OLIF techniques in managing lumbar degenerative diseas.
