Oblique Lumbar Interbody Fusion at L5-S1 Segment Through an Approach Between the Psoas Muscle and the Great Vessels – Lumbar Fusion

Day Case Lumbar Fusion Surgery

The article discusses the oblique lateral interbody fusion (OLIF) technique for treating spinal conditions in the L5-S1 segment of the lumbar spine. While OLIF has been widely used in other lumbar segments, its applicability for lumbosacral fusion has been a subject of concern in the spinal surgery community. The study examines a cohort of 20 patients who underwent interbody fusion at the L5-S1 level using the OLIF technique. The surgical procedure involved discectomy and endplate preparation through a surgical window created on the anterolateral side of the L5-S1 disc. A supplementary cage insertion approach was used for secure interbody fusion cage placement. Follow-up evaluations showed significant reductions in lower back and limb pain, as well as improvements in the Oswestry disability index. Radiographic evaluations confirmed successful lumbosacral junction reconstruction and bony fusion. The study concludes that the OLIF technique can be a feasible approach for lumbosacral reconstruction, dependent on thorough preoperative planning and precise intraoperative techniques

ABSTRACT

Over the years, the oblique lateral interbody fusion (OLIF) technique has gained significant recognition for treating various spinal conditions in lumbar segments L2-L5. However, the adoption of OLIF for the L5-S1 segment has not been widely embraced by the spinal surgery community, given that significant concerns remain regarding the applicability of OLIF for lumbosacral fusion. In this study, a cohort of 20 patients underwent interbody fusion at the L5-S1 level using the OLIF technique through a single retroperitoneal oblique approach positioned between the Psoas muscle and the great vessels. The procedure involved discectomy and endplate preparation accomplished through a surgical window created on the anterolateral side of the L5-S1 disc. For secure interbody fusion cage placement, a supplementary cage insertion approach was employed. All patients were followed up for a minimum of 12 months. The mean preoperative visual analog scale (VAS) score for lower back pain was 6.3 ± 1.5 and experienced a significant reduction to 1.2 ± 0.8 at 12 months. The VAS score for lower limb pain significantly decreased from 5.6 ± 1.4 preoperatively to 0.8 ± 0.3 at 12 months after the surgery. Furthermore, the preoperative Oswestry disability index (ODI) improved from 82.4% ± 16.2% to 8.1% ± 2.0% at 12 months. Radiographic evaluations after surgery confirmed improved lumbosacral junction reconstruction for all patients. At the final follow-up, successful bony fusion was observed in all cases. Based on these findings, the OLIF technique for L5-S1 fusion represents an attainable approach for lumbosacral reconstruction. The procedure’s success hinges on a comprehensive preoperative plan and precise intraoperative techniques.
