Abstract：Objective To compare the effect of robot navigation system (Tian Ji robot system) plus 3D printing and traditional C-arm X-ray fluoroscopy in assisting percutaneous kyphoplasty (PKP) or percutaneous vertebroplasty (PVP) for treatment of Kümmell disease. Methods A retrospective case-control study was conducted to analyze the clinical data of 40 patients with Kümmell disease treated at Honghui Hospital Affiliated to Xian Jiaotong University School of Medicine from December 2017 to February 2019, including 12 males and 28 females, with an average age of 56.4 years (range, 42-71 years). In observation group, 20 patients underwent PKP or PVP assisted by the robot navigation system and 3D printing. In control group, 20 patients underwent PKP or PVP assisted by the traditional C-arm X-ray fluoroscopy. The operation time and incidence of complications were observed. The visual analogue scale (VAS), Oswestry disability index (ODI), Cobb angle and anterior vertebral height were compared before operation, 1 day and 3 months after operation. Results All patients were followed up for 3.5-8.6 months (mean, 6.7 months). The operation time in control group was (32.2±5.8)minutes, compared with (26.7±3.6)minutes in observation group (P<0.05). The incidence of cement leakage was 0% (0/20) in the observation group and 5% (1/20) in control group (P＞0.05). One day after operation, in observation group and control group, the VAS was (2.1±0.3)points and (3.7±0.8)points, the ODI was 14.3±1.8 and 25.5±5.7, the Cobb angle was (20.6±1.2)° and (22.4±0.6)°, and the anterior height of vertebral body was (21.2±0.8)mm and (17.6±0.7)mm, respectively, showing significant improvement compared with those before operation (P<0.01). Three months after operation, in observation group and control group, the VAS was (1.8±0.4)points and (2.8±0.8)points, the ODI was 12.3±1.5 and 21.6±2.3, the Cobb angle was (18.1±0.8) ° and (20.5±1.6)°, and the anterior height of vertebral body was (20.1±1.8)mm and (16.8±1.3)mm, showing no significant difference compared with those at day 1 after operation (P>0.05). There were significant differences in the VAS, ODI, Cobb angle and anterior vertebral height between the two groups 1 day and 3 months after operation (P<0.01). Conclusion For Kümmell disease, with assistance with the robot navigation system combined with 3D printing, PKP or PVP can more effectively reduce the pain of patients, improve the quality of life, restore the anterior height of vertebral body, and realize the individualized treatment in comparison with the traditional C-arm X-ray fluoroscopy.
