Application of artificial intelligence 3D printing guide to guide the insertion point and angle in thoracolumbar fracture surgery
Aim To explore the application of artificial intelligence 3D printing guide to guide the insertion point and angle in thoracolumbar fracture surgery.Methods 73 patients with thoracolumbar vertebral fractures were selected and divided into two groups.The study group used artificial intelligence 3D printing guide plate technology to assist in pedicle screw implantation surgery,while the control group used CT evaluation and prediction before surgery.Compare the surgical time,intraoperative X-ray exposure frequency,intraoperative blood loss,blood transfusion volume,number and accuracy of nail placement,and incidence of complications between two groups;Compare the height ratio before and 6 months after surgery,sagittal kyphosis Cobb angle,as well as the Japanese orthopaedic association(JOA)and visual analog scale(VAS)scores for thoracolumbar spine between two groups.Results Com-pared with the control group,the study group showed a decrease in surgical time,intraoperative X-ray exposure frequency,blood loss,blood transfusion volume,screw sagittal plane angle,difference in internal inclination angle,and difference in horizontal position of the screw insertion point;The accuracy of nail placement increased(P＜0.05).Compared with preoperative results,the height ratio and JOA score of the injured vertebrae in both groups increased after surgery,while the Cobb angle and VAS score of sagittal kyphosis de-creased.Moreover,the changes in the study group were more significant than those in the control group(P＜0.05).There was no significant difference in the total incidence of complications between the two groups of patients(P＞0.05).Conclusion The use of artificial intelligence printing guide to guide the insertion point and angle can effectively reduce the operation time,X-ray exposure times and bleeding,improve the accuracy of nail placement,and lead to better surgical effect.
