Name of journal: World neurosurgeryAbstract: CONCLUSIONS: Our breach rates with ExcelsiusGPS were low and consistent with others reported in the literature, as well as with other robotic systems. Our series demonstrates equivalent accuracy of placement of PPS with this robotic platform compared to fluoroscopic guidance and suggests a relatively short learning curve.

We graded accuracy of screws on CT imaging and compared to a prior cohort of 90 PPS placed using fluoroscopy. We also analyzed the effect of various demographic and perioperative metrics on accuracy.OBJECTIVE: Percutaneous pedicle screws (PPS) are used to stabilize the spine after interbody fusion in minimally invasive approaches. Recently, robotic assistance has been developed to improve the accuracy of PPS. We report our initial experience with ExcelsiusGPS and compare its accuracy to our historical cohort of fluoroscopy-guided PPS.RESULTS: We placed 103 PPS in the first 20 consecutive patients with postoperative CT imaging using ExcelsiusGPS. All screws were placed at L2 to S1. Our robot-assisted cohort had six breaches, with only two breaches greater than 2mm, yielding an overall breach rate of 5.8% and a significant breach rate of 1.9%. In comparison, our fluoroscopy-guided cohort had a breach rate of 3.3% and a significant breach rate of 1.1%, which was not significantly different. More breaches occurred in the first half of cases, suggesting a learning curve with robotic assistance. No demographic or perioperative metrics had a significant effect on accuracy.All authors: Fayed I, Makariou E, Sandhu FA, Sayah A, Tai A, Triano M, Voyadzis JMFiscal year: FY2021Digital Object Identifier: Date added to catalog: 2020-09-02
