Purpose of the study

To evaluate clinical outcomes and complications of extreme lumbar interbody fusion (XLIF) in spinal revision surgery comparing our data with the available literature evidence about other fusion techniques.

Materials and methods

Retrospective analysis of patients underwent revision surgery with XLIF as interbody fusion technique. Demographic, comorbidity, surgical data, clinical results, and intraoperative and postoperative complications were recorded.


36 patients, with a minimum follow-up of 28 ± 11.5 months, were included in the analysis. 41 levels were fused with XLIF. The mean number of previous spine surgery was 1.5 ± 0.7. Mean improvement in back pain and leg pain on VAS was 5.6 ± 1.4 (p 


XLIF is a reasonably safe and effective fusion technique in revision surgery that allows valid arthrodesis avoiding scarred tissue created by previous surgical approaches. Especially, XLIF reduces the risk of nerve root lesions, postoperative radiculitis, and durotomies compared to posterior fusion techniques.
