3D打印个体化模型在复杂踝关节骨折术中的应用
Application of 3D printed individualized model in complex ankle fracture surgery
摘要
Abstract
Objective To explore the application effect of 3D printed individualized model in the treatment of complex ankle fractures(AF).Methods Patients with complex AF admitted to our hospital from July 2021 to October 2022 were selected and divided into the control group and the observation group using a random number table method,with 50 cases in each group.Patients in the control group were received minimally invasive reduction and internal fixation,while these in the observation group were given minimally invasive reduction and internal fixation under the guidance of 3D printed individualized model.The surgical conditions,ankle joint reduction,stress indicators[norepinephrine(NE)and angiotensin Ⅱ(AngⅡ)],ankle function and postoperative complications were compared between the two groups.Results There were 2 patients in the observation group and 3 patients in the control group were lost to follow-up 12 months after surgery.Compared with the control group,the observation group showed a decrease in the intraoperative blood loss,shortened surgical time,hospitalization time,and weight-bearing activity time,and an increase in the anatomical reduction rate(P<0.05).The observation group had lower serum levels of NE and AngⅡ 1 and 3 days after surgery(P<0.05)and higher Kofoed score and American Orthopedic Foot and Ankle Society(AOFAS)scores 1,6,and 12 months after surgery(P<0.05),as well as lower incidence of postoperative complications(P<0.05)than those in the control group.Conclusion For the treatment of complex AF,3D printed individualized model assisted the formulation of minimally invasive reduction and fixation surgical plans before surgery can shorten surgical time,reduce stress injury,decrease the risk of complications,and simultaneously increase the anatomical reduction rate and improve ankle joint function,thereby accelerating postoperative recovery of patients.关键词
