Clinical outcomes of navigation-assisted versus fluoroscopy-guided UBE-ULBD in single-level lumbar spinal stenosis: a retrospective study

Navigation-assisted UBE-ULBD can significantly improve surgical efficiency and markedly reduce intraoperative radiation exposure for surgeons, while demonstrating comparable safety and clinical efficacy to conventional fluoroscopy-guided procedures. These advantages highlight its potential clinical value as a safer and more efficient alternative for minimally invasive decompression in lumbar spinal stenosis.
