Abstract: Background: Spondylodiscitis is an infectious condition affecting the vertebral body, intervertebral disc, and surrounding paravertebral tissues. Reconstruction of the lumbosacral segment is technically demanding due to its biomechanical conditions and anatomical characteristics. This clinical outcome study aims to provide significant insights into the efficacy and advantages of using S2AI screws in a single - stage posterior approach to address persistent instability, recurrent infection, and facilitate fusion in severe spondylodiscitis. Methods: Six patients diagnosed with infective lumbo sacral spondylodiscitis and underwent surgical debridement and fixation between August 2022 and March 2024 were enrolled in this study. Patient demographic, pre surgery and post - surgery Visual Analog Score (VAS), Oswestry Disability Index (ODI), and post operative complications were analysed. Results: The six patients were monitored for an average of 14 months. VAS declined in all six patients. The average preoperative VAS was 8.17 and dropped significantly to an average of 2.6 following surgery. ODI showed a continuous increase in scores over the course of the follow - up period. The average ODI score prior to surgery was 81, and it decreased substantially to an average score of 32 after surgery. Conclusion: Utilizing the S2AI fixation method for lumbosacral spondylodiscitis is a reliable and safe treatment option that can yield promising outcome in restoring lumbosacral stability.
