Application Of Orthopedic Surgery Robot Combined With 3D Printing Technology In Spinal Tumor Surgery

Objective: A comparative study of orthopedic surgical robots combined with 3D printing technology to assist spinal tumor surgery versus traditional spinal tumor surgery to discover the advantages and shortcomings of 3D printing technology applied in spinal surgery.Methods: Patients with spinal tumor surgery completed from January 2021 to December 2022 were retrospectively recruited.There were 14 patients with orthopedic surgery robot combined with 3D printing assisted spine tumor surgery and 31 patients with traditional spine tumor surgery.The postoperative conditions and prognostic differences between the two surgeries were compared.The data were mainly compared and analyzed in terms of operative time,bleeding volume,accuracy of pedicle screw implantation position,hospital stay,preoperative and postoperative visual analogue scale(VAS)for low back pain,preoperative and postoperative Oswestry dysfunction index(ODI)functional score,and postoperative complication rate in the two groups.Results: A total of 45 patients were included in this study,and all of them completed the surgery successfully without serious complications.There was no statistically significant difference between the two surgical procedures in terms of operative time,early complication rate,and accuracy of pedicle screw implantation position(P > 0.05).The robot combined with 3D printing group had a shorter hospital stay than the traditional surgery group(P < 0.05).Intraoperative bleeding was significantly less in the robotic combined 3D printing group than in the conventional surgery group(P < 0.05).According to the follow-up,the ODI scores and VAS scores of patients in both groups improved significantly over time after surgery(P < 0.05).The differences in ODI scores and VAS scores at the corresponding time points between the two groups were not statistically significant(P > 0.05).Conclusion: Orthopedic surgical robot combined with 3D printing technology can effectively reduce intraoperative blood loss and hospital stay of patients in spinal tumor surgery.This study included relatively few cases,and the clinical application of orthopedic surgical robot combined with 3D printing technology in spine surgery is still in its infancy,which needs further research and exploration.
