    AbstractThe prone lateral transpsoas approach for lumbar interbody fusion and posterior instrumentation enables a large surface area implant without disruption of the posterior spine musculature from a single position.1,2 The addition of virtual live fluoroscopy instrument tracking navigation to surgery provides multiple benefits, including a reduction in patient and surgeon radiation exposure, highly accurate and dynamic spatial tool localization, and flexible equipment and patient positioning.3,4 Here, we highlight the use of virtual live fluoroscopy in prone lateral spine surgery. A 75-year-old man presented with prior L3-L5 fusion and progressive lower extremity pain and weakness. Using the described techniques, the patient underwent a lateral retroperitoneal interbody fusion and posterior instrumentation at L2-L3. The operation proceeded without complication, and the patient reported improved ambulation at 6-week follow-up. The prone lateral transpsoas approach and minimally invasive posterior instrumentation for lumbar interbody fusion permits effective fusion without significant posterior muscle disruption from a single position. The integration of virtual live fluoroscopy enables real-time instrument tracking throughout the minimally invasive case, with reductions in patient and surgeon radiation exposure. Video 1 depicts the use and benefits of this technology in lateral spine surgery. Compared with computed tomography-guided navigation, virtual live fluoroscopy technology enables rapid remapping to iatrogenic anatomic changes for more fluid progression through the operation.5 Virtual live fluoroscopy instrument tracking is a valuable tool that increases the safety and efficiency of single-position lateral spine surgery.Copyright © 2022 Elsevier Inc.
