Abstract
Background: Transpedicular screw placement remains the gold standard technique for stabilization of the lumbar spine. Material and methods: This is a retrospective study that analyzes patients that underwent the spinal stabilization surgical procedure. We compared results from two independent neurosurgical centers. In the years 2012-2015, the O-arm and StealthStation neuronavigation system was used for implantation of transpedicular screws. From 2018 to 2020 the transcutaneous pedicle screw placement procedure was performed using a standard C-arm device. Results: In 208 procedures performed with the O-arm device, the accuracy of screw position was 98.08%. Screw repositioning was necessary in 1.92% of all cases. In the 30 procedures that were performed using the C-arm, the accuracy of the screws was 86.7% and the screw reposition procedure accounted for 10% (in one case screws were not replaced due to clinical sequelae). Conclusions: Our data show that the spinal fusion with the O-arm tool has more accuracy, thus might be more indicated in procedures that require minimally invasive spinal stabilization.
