'天玑'骨科机器人辅助下经皮椎弓根螺钉植钉安全性评价

OBJECTIVE: To evaluate the safety of TiRobot-guided percutaneous transpedicular screw implantation. METHODS: The medical records of 158 patients with thoracolumbar fractures and lumbar degenerative diseases who underwent percutaneous transpedicular screw implantation were retrospectively analyzed between January 2018 and December 2020. The patients were divided into trial group (TiRobot-guided screw implantation, 86 cases) and control group (fluoroscopy-guided screw implantation, 72 cases). There was no significant difference in gender, age, pathology, lesion segment, and the average number of screw implantation per case (P>0.05). The operation time, fluoroscopic dose, fluoroscopic time, and fluoroscopic frequency were compared between the two groups. One day postoperatively, the convergence angle was measured and the penetration of the pedicle cortex was evaluated according to Gertzbein-Robbins classification standard. RESULTS: The operation time, fluoroscopic dose, fluoroscopic time, and fluoroscopic frequency of the trial group were significantly lesser than those of control group (P
