Spondylolisthesis Reduction and Changes in Sagittal Alignment Following Single-Position Lateral Versus Lateral-Then-Prone Oblique Lumbar Interbody Fusion With Navigation-Assisted Posterior Percutaneous Instrumentation

Key Points

• The study aims to compare operative durations and outcomes between two techniques for lumbar interbody fusion.
• Retrospective analysis conducted at a single center
• Compared single-position lateral OLIF and dual-position lateral-then-prone OLIF
• Assessed operative duration, pedicle screw accuracy, and spondylolisthesis reduction
• Single-position lateral OLIF had shorter operative duration than dual-position OLIF
• No significant difference in pedicle screw accuracy between the two methods
• Both approaches had comparable impacts on postoperative alignment and complication rates
