Objective: To assess the accuracy & efficiency of screws and spinal stabilization using O-arm 3D imaging system and stealth navigation in neurosurgical department.
Methods: Single center, retrospective, clinical study. All patients, who underwent spinal stabilization utilizing the O-arm 3-dimensional (3D) imaging system as an intraoperative 3D scan, together with a navigation system received postoperative CT scanning of the correspondent spinal level were included in our study. The accuracy of each screw was determined radiologically; using validated classification methods.
Results: During a period of 5 years (January 2012 to December 2016) a total of 3160 screws were placed in 606 Patients. In 97.1 %, the screws were correctly placed. 1.8% of the screws were revised during the same procedure. When the surgeon perceived the screws to be correctly placed, the CT scan verified his assessment in 98.5% of the cases, only 6 patients required to be directly re-operated during the same hospital stay.
Conclusion: The use of the O-arm in combination with a navigation system prove to be accurate and reliable for screw placement in all spinal levels.
