This randomized controlled trial evaluates ultra-low radiation imaging with image enhancement (mFluoro) versus conventional fluoroscopy during single-level XLIF lateral interbody fusion in 57 analyzed patients. Results show marked reductions in OR staff exposure (surgeon −72.1%, assistant −76.1%, scrub nurse −67.5%), lower patient DAP (−66.1%), fewer images, and shorter procedure times without increased complications.
The study used live dosimeters, standardized protocols, and optical reposition-assist technology (LessRay/PULSE) with Cios Spin. Findings support ULRI+IE as an effective strategy to decrease occupational and patient radiation during minimally invasive lateral spine surgery, noting limitations including lack of surgeon blinding and early learning-curve crossovers.
