A Review of Techniques, Time Demand, Radiation Exposure, and Outcomes of Skin-anchored Intraoperative 3D Navigation in Minimally Invasive Lumbar Spinal Surgery

Abstract: Study Design. Retrospective cohort. Objective. To describe our technique for and evaluate the time demand, radiation exposure and outcomes of skin-anchored intraoperative three-dimensional navigation (ION) in minimally invasive (MIS) lumbar surgery, and to compare these parameters to 2D fluoroscopy for MI-TLIF. Summary of Background Data. Limited visualization of anatomic landmarks and narrow access corridor… Show more

“…The median set up time using the skin tracking system was 23 minutes, with over 70% of cases being set-up in <25 minutes, demonstrating that the preoperative set up was not laborious. Similar to studies above, they observed a 29% reduction in the median radiation dose to the patient as compared to fluoroscopic procedures (31).…”

“…Their study demonstrated the efficacy of a less bulky registration system that could be used for cases involving smaller incisions. Their navigation cohort resulted in significantly shorter operative times (median 92 vs. 108 minutes, P<0.0001) and less blood loss (median 25 vs. 50 mL, P=0.007), as compared to the fluoroscopy group (31). And while their navigation group required additional time for image acquisition, the total time (image acquisition + surgical procedure) was only slightly greater than that of procedures using fluoroscopy alone (median 113 vs. 108 mins).…”

“…3-D CT navigation technology is widely used for the placement of spinal implants in both open and minimally invasive spine procedures. CT navigation allows for realtime visualization of the spinal anatomy in the axial, coronal, and sagittal planes and is associated with increased accuracy of pedicle screw placement, while potentially decreasing radiation exposure (27,28). An emphasis on obtaining the utmost accuracy lends this technology well to spinal endoscopy, which hinges on absolute accuracy and precision in localization.…”

“…This integrative map is displayed on a screen, allowing the surgeon to see a virtual representation of the operation in real-time. The advantages of image-guided navigation compared to standard intraoperative fluoroscopy have been well studied in posterior instrumentation of the spine, including increased accuracy of pedicle screw placement and decreased radiation exposure (13) for the surgeon and operating room staff (14,15).…”
