Int J Spine Surg 2025, 19 (1) 70-80
Surgical Technique and Study Overview
• Single-position prone lateral lumbar interbody fusion improves surgery efficiency and safety.
• Navigation enhances precision in pedicle screw placement and reduces radiation exposure.
• Study involved 15 patients with simultaneous cage and screw placement using intraoperative navigation.
• Mean surgery duration was 263 ± 94 minutes with blood loss of 315 ± 143 mL.
• No major complications reported, except for two cases of cerebrospinal fluid leakage.
Clinical Outcomes and Findings
• Significant improvements in Oswestry Disability Index (ODI) scores post-surgery (51.38 to 32.81).
• Segmental lordosis improved significantly from 3.26° to 13.09° (P < 0.001).
• No significant changes in total lumbar lordosis or sagittal vertical axis.
Technical Insights and Considerations
• Intraoperative navigation used for cage and screw placement without additional fluoroscopy.
• Radiation exposure reduced for surgical teams due to minimized fluoroscopy use.
• Simultaneous screw and cage placement guided by navigation and neuromonitoring.
• Challenges include navigation system inaccuracies due to segmental distraction.
• Learning curve observed with new workflow implementation affecting time savings.
