Lumbar degenerative diseases pose major health challenges, driving the search for advanced surgical solutions. Oblique lumbar interbody fusion (OLIF) is a promising technique, but it’s unclear whether combining OLIF with anterior screw fixation (OLIF-AF) is superior to using OLIF with posterior pedicle fixation (OLIF-PF). This investigation sought to clarify this by comparing these two approaches.
For lumbar degenerative diseases, OLIF-AF presents favorable intraoperative outcomes like reduced blood loss and shorter surgical durations. However, it does not markedly differ in patient-reported outcomes or radiographic assessments from OLIF-PF.

This investigation sought to clarify this by comparing these two approaches.
Overall, 5 studies involving 271 patients compared OLIF-AF and OLIF-PF. In this systematic review and meta-analysis, the key metrics analyzed included intraoperative parameters, fusion rates, patient-reported measures (pain scores and functional evaluation), and imaging findings.
OLIF-AF and OLIF-PF exhibited similar fusion rates. OLIF-AF was associated with less blood loss and shorter surgery times. However, patient pain levels, function, and radiographic results did not differ markedly between the two techniques.
OLIF-AF provided benefits in terms of reduced blood loss and quicker surgeries but didn’t offer superior patient outcomes or fusion rates when compared to OLIF-PF. Future research involving larger, more diverse cohorts and longer follow-ups is crucial to validate these preliminary findings and understand the true clinical impact of OLIF techniques in tackling lumbar degenerative diseases.
