Abstract：Objective To investigate the application value of 3D-CT reconstruction combined with the establishment of simulated screw path in the treatment of lumbar fractures.Methods A total of 126 patients with lumbar fracture who un-derwent pedicle screw internal fixation from January 2019 to January 2023 were selected and randomly divided into the obser-vation group(n =63)and the control group(n =63)according to random number table method.The observation group re-ceived 3D-CT reconstruction combined with simulated screw path establishment guidance surgery,and the control group re-ceived conventional anatomic marker combined with C-arm X-ray positioning guidance surgery.The excellent and good rate,time and blood loss of pedicle screw fixation in the two groups were observed and compared.The scores of Oswestry Disability Index(ODI),Japanese Orthopaedic Association(JOA)score,Fugl-Meyer Motor Function Assessment Scale(FMA)before and after surger,and postoperative lumbar function recovery were evaluated,and postoperative complications were observed.Results The excellent and good rate of pedicle screw fixation in observation group was 94.67%(302/319),which was higher than that in control group[88.79%(285/321)](P＜0.01).The time of pedicle screw fixation in the observation group was shorter than that in the control group,and the blood loss of pedicle screw fixation was less than that in the control group(P＜0.01).At 6 months after operation,ODI and JOA scores in observation group were lower than those in control group,while FMA scores were higher than those in control group(P＜0.05,P＜0.01).The incidence of postoperative com-plications in observation group was lower than that in control group(P＜0.05).Conclusion The use of 3D-CT reconstruc-tion combined with the establishment of simulated screw path to guide the operation can effectively improve the excellent and good rate of pedicle internal fixation in patients with lumbar fracture,shorten the time of pedicle screw fixation,reduce the amount of blood loss,reduce the risk of postoperative complications,and promote the recovery of lumbar function.
