Abstract：Objective To explore the early efficacy of robot-assisted percutaneous kyphoplasty(PKP)for the treatment of osteoporotic thoracolumbar compression fractures.Methods A retrospective analysis was conduc-ted on 70 patients with single segment osteoporotic thoracolumbar compression fractures treated with PKP at the Tra-ditional Chinese Medicine Hospital of Ziyang.There were 23 males and 47 females aged 65-84(mean 72.5)years.Patients were divided into the robot group(n=36)or the traditional group(n=34)based on the surgical method.The robotic group underwent PKP with the assistance of Zuo Hang's minimally invasive spinal surgery robot for lo-calization and puncture,while the traditional group underwent PKP by using a C-arm X-ray machine.The general data,operation time,fluoroscopy frequency,cement distribution,leakage of bone cement,VAS score on the first day after surgery and Cobb angle were compared between the two groups.Results The intraoperative fluoroscopy fre-quency of the robot group was significantly less than that of the traditional group(20.0±3.9 vs.23.6±4.6),and the excellent rate of bone cement distribution was much higher(88.9%vs.70.6%,both P<0.05).The operation time[min,25(20,30)vs.25(20,30)],bone cement leakage rate(13.9%vs.23.5%),VAS scores 1 d after sur-gery[2(1,4)vs.2(2,4)],and posterior Cobb angle(9.1°±2.1° vs.9.5°±2.3°)was smaller in the robot group,but the differences were insignificant(all P>0.05).Conclusion Robot-assisted PKP in the treatment of thoracolumbar compression fractures can improve puncture accuracy,reduce intraoperative fluoroscopy,and optimize bone cement distribution to ensure better early efficacy.
