ObjectiveLumbar pedicle screw placement surgery involves various assistive technologies, including fluoroscopic, stereotactic, or robotic navigation and intraoperative neuromonitoring (IONM). We aimed to discern neurosurgeons' preferences for screw placement techniques and IONM utility, while also considering the influence of experience.MethodsA survey was distributed to members of the Congress of Neurological Surgeons using REDCap software, collecting demographic data and querying preferred techniques for screw placement and IONM modalities. Opinions on IONM use during stereotactic or robotic navigation were also obtained. Responses were analyzed using Pearson's Chi Square and ANOVA tests via R software.ResultsOf 188 responses, 35.5% (n=67) reported 1-10 years of experience and 64.5% (n=121) reported ≥11 years. Less experienced neurosurgeons utilized stereotactic navigation more than those with greater experience (p < 0.001). Seasoned neurosurgeons utilized fluoroscopic guidance more often (p = 0.038). Less experienced neurosurgeons employed 1.69 (±0.11) techniques for their fixation surgeries compared to 1.50 (±0.0.8) for more experienced neurosurgeons. Robotic navigation utilization was low and comparable between the groups. Surgeons employing multiple techniques utilized t-EMG the most (62.1%, p = 0.024). No strong opinions emerged on the necessity of multi-modality IONM with robotic or stereotactic navigation.ConclusionsThis national survey shows that stereotactic navigation is the predominant technique for pedicle screw placement among less experienced neurosurgeons, with seasoned neurosurgeons leaning towards fluoroscopic guidance. Robotic guidance was the least utilized technique with no observed difference based on experience. Neurosurgeons employing multiple techniques use IONM the most, compared with surgeons who only use stereotactic navigation and/or robotic guidance.Copyright © 2024 Elsevier Inc. All rights reserved.
