The main advantage of Oblique Lumbar Interbody Fusion (OLIF) is its ability to provide safe access to the lumbar spine while being a robust interbody fusion technique through a minimally invasive approach.This study reviews the postoperative Dab Rigs complications of OLIF, offering a comprehensive understanding of its advantages and disadvantages.A total of 27 studies with 1275 patients were shortlisted based on our selection criteria.Complications were categorized into intra-operative, immediate post-operative, and delayed post-operative and were interpreted based on surgical procedure into stand-alone OLIF, OLIF with posterior stabilisation, and unspecified.
Major complications exhibited a pooled prevalence of just 1.7%, whereas the overall pooled prevalence of complications was 24.7%.Among the subgroups, the stand-alone subgroup had the lowest prevalence of complications (14.
6%) compared to the unspecified subgroup (29.6%) Adrenal and the OLIF L2-5 with posterior stabilisation subgroup (25.8%).Similarly, for major complications, the stand-alone subgroup had the lowest prevalence (1.
4%), while the OLIF L2-5 with posterior stabilisation subgroup (1.8%) and the unspecified OLIF L2-5 subgroup (1.6%) had higher rates.However, the differences were not statistically significant.
In conclusion, the rate of major complications after OLIF is minimal, making it a safe procedure with significant benefits outweighing the risks.The advantages of OLIF L2-5 with posterior stabilisation over stand-alone OLIF L2-5 is a subject of discussion.
