Degenerative disc and facet joint disease are prevalent conditions in the aging population, often leading to disability. Oblique lumbar interbody fusion (OLIF) /anterior to psoas (ATP) surgeries provide effective treatment by stabilizing the affected segment, offering indirect decompression of neural elements, and correcting coronal and sagittal deformities. Other indications include instability, infection, tumour and revision surgery. This review aims to assess the anatomical and technical considerations essential for performing OLIF/ATP surgeries between L2-L5 . The surgical techniques and anatomical and technical considerations for lumbar interbody fusion using OLIF/ATP at the L2/3, L3/4, and L4/5 levels were examined. This review outlines anatomical and technical considerations for a successful ATP/OLIF procedure L2-L5. This study thoroughly reviews the literature on OLIF/ATP and provides recommendations and guidelines on anatomical and technical considerations for ATP/OLIF procedures at L2/3, L3/4 and L4/5.
