Purpose This study aimed to demonstrate that the augmented reality computer-assisted spine surgery (ARCASS) system is clinically feasible for percutaneous vertebroplasty (PVP). Methods This prospective case-control study included the patients undergoing PVP under the assistance of the ARCASS system between July 1, 2013, and October 31, 2014. The control group was the age- and gender-matched patients who underwent standard PVP and met the same eligible criteria as the case group. Primary outcome was the frequency of fluoroscopy. Secondary outcomes were the accuracy of bony entry point and operative time. Results Eighteen patients were included in this study: 9 patients with 11 levels of lesions in the ARCASS group and 9 patients with 10 levels of lesions in the control group. Compared with the control group, the ARCASS group had significantly less frequency of fluoroscopy (6 vs. 18, P < 0.001) and shorter operative time (78 vs. 205 s, P < 0.001) during the process of entry point identification and local anesthesia, which started from the registration of skin entry point at lesion site to the end of bony entry point identification. Regarding accuracy, the ARCASS group had significant greater proportion of 'good' entry point than the control group on lateral views (81.8% vs. 30.0%, P = 0.028) and anteroposterior views (72.7% vs. 20.0%, P = 0.020). Conclusion This study revealed that the ARCASS system was clinically feasible for PVP. The guidance of ARCASS system provided more accurate bony entry point with reduced operative time and unnecessary radiation exposure.
