Abstract：Objective To observe the application effect of fractured segment simulated pedicle screw channel established using computer simulation software in internal fixation of lumbar vertebral fractures.Methods A total of 114 patients with lumbar vertebral fractures who were admitted to Henan Provincial People's Hospital from March 2020 to March 2023 were selected.According to the random number table method,the patients were divided into control group(57 cases,conventional screw placement)and study group(57 cases,internal fixation with simulated pedicle screw channel established using computer simulation software).Surgical indicators,screw placement,imaging parameters,lumbar function recovery and postoperative complications were compared between the two groups.Results Surgical time,length of postoperative hospital stay,and the duration of single screw placement in the study group were shorter than those in the control group,total intraoperative blood loss,fluoroscopy times and bleeding volume during placement in the study group were less than in the control group,cases with single screw placement in the upright position in the study group were more than those in the control group(all P＜0.05).At the last follow-up after surgery,anterior vertebral height ratio(AVHR)and the corrected degree of sagittal curvature in the study group was higher than that in the control group,Cobb angle was smaller than that in the control group,Oswestry disability index(ODI)score was lower than control group,Japanese Orthopedic Association(JOA)score was higher than control group(P＜0.05).Conclusion Applying simulated pedicle screw channel established using computer simulation software in internal fixation of lumbar vertebral fractures can achieve good results.Compared with conventional screw placement,it can accelerate the recovery time and promote the recovery of lumbar function.
