This study summarizes the technical aspects of OLIF as a salvage surgery and the preliminary outcomes of a series of cases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and methods<\/jats:title><jats:p>A retrospective review of patients with leg or back pain induced by pseudoarthrosis or adjacent segment disease after posterior lumbar interbody fusion\/transforaminal lumbar interbody fusion was done. These patients underwent salvage OLIF surgeries in our institution from January 2021 to March 2022. Variables such as the demographic, clinical, surgical, and radiological characteristics of the enrolled patients were recorded and analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Eight patients (five females and three males; mean age 69.1\u2009\u00b1\u20095.7 years, range 63\u201380 years) were enrolled in this study. The mean operative time was 286.25\u2005min (range: 230\u2013440\u2005min), and the estimated blood loss was 90\u2005ml (range: 50\u2013150\u2005ml). Only one of the eight patients experienced a complication of lower limb motor weakness, which disappeared within 5 days after surgery. The latest data showed that the mean intervertebral space height increased from 8.36\u2005mm preoperatively to 12.70\u2005mm and the mean segmentary lordosis increased from 8.92\u00b0 preoperatively to 15.05\u00b0. Bone fusion was achieved in all but one patient, who was followed up for only 3 months. The JOA scores Japanese Orthopaedic Association (JOA) Scores for low back pain of all patients significantly improved at the final follow-up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>OLIF provides a safe and effective salvage strategy for patients with failed posterior intervertebral fusion surgery.
