Abstract

Abstract: Objective To evaluate the clinical outcomes of robot-assisted percutaneous vertebroplasty (PVP) versus manual PVP in treating osteoporotic vertebral compression fractures (OVCF), and explore the advantages of robotic assistance for clinical decision-making. Methods Patients who underwent single-level PVP for OVCF at the Department of Joint Surgery and Bone Tumor, Beijing Shijitan Hospital, Capital Medical University, between April 2021 and April 2025 were enrolled. The robot group (n=29) and manual PVP group (control, n=88) were followed-up for 1 month. Parameters compared included: total hospital stay, operative time, cement volume, cement leakage rate, nerve injury rate, intraoperative fluoroscopy number, first-attempt success rate of puncture, postoperative versus preoperative anterior vertebral height difference, Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores preoperatively, at 1-day and 1-month postoperatively. Results No statistically significant differences existed in baseline characteristics (gender, age, fracture-to-surgery interval, and fracture distribution) between groups (P>0.05). The number of intraoperative fluoroscopy times and the ODI index on the first day after surgery in the robot group were significantly lower than those in the control group (P<0.05), and the first-attempt success rate of puncture was significantly higher than that in the control group (P<0.05). There were no statistically significant differences in the other parameters between the two groups (P>0.05). Conclusion Both robot-assisted PVP and manual PVP have good clinical efficacy in the treatment of OVCF. Robot-assisted PVP can reduce the number of intraoperative fluoroscopy times and may have more advantages in improving the first-attempt success rate of puncture and early postoperative lumbar function. However, its reliability needs to be further verified through large-sample randomized controlled studies with multivariate analysis.
