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.

Purpose: Lumbar degenerative diseases impose a substantial health burden, prompting the exploration of advanced surgical approaches such as Oblique Lumbar Interbody Fusion (OLIF). This meta-analysis aims to evaluate the comparative efficacy of OLIF with anterior screw fixation (OLIF-AF) against OLIF with posterior pedicle fixation (OLIF-PF) in addressing these conditions.

Methods: A systematic search across multiple databases identified five studies meeting inclusion criteria, incorporating a total of 271 patients.
