术前3D打印技术联合T型钢板弹性支撑固定治疗在后柱复杂性髋臼骨折患者中的应用效果
Application effect of preoperative 3D printing technique combined with T-plate elastic support fixation therapy in patients with posterior column complex acetabular fracture
摘要
Abstract
Objective To investigate the application effect of preoperative 3D printing technique combined with T-plate elastic support fixation therapy in patients with posterior column complex acetabular fracture.Methods The clinical data of 54 patients with posterior column complex acetabular fracture were retrospectively analyzed,and they were divided into control group or study group according to operative methods,with 27 cases in each group.Patients of both groups received operative reduction via Kocher-Langenbeck approach with general anesthesia,and the control group was treated with T-plate elastic support fixation,while the study group employed preoperative 3D printing technique to print patient's acetabular fracture model for therapeutic guidance.The operative indices(operation duration,intraoperative bleeding volume,intraoperative blood transfusion volume,intraoperative fluoroscopic frequency),and fracture reduction quality,hip joint function recovery,as well as the occurrence of complications during perioperative period and follow-up were compared between patients of the two groups.Results The operative duration,intraoperative bleeding volume,intraoperative blood transfusion volume,and intraoperative fluoroscopic frequency of the study group were shorter or less than those of the control group,and fracture reduction quality was superior to that of the control group(P＜0.05).There was statistically significant difference in Charnley hip joint function score between the two groups(Finter-group=8.316,Pinter.group＜0.001),therein,after 3 and 6 months of operation,the Charnley hip joint function score of the study group was higher than that of the control group(P＜0.05);furthermore,the Charnley hip joint function score of the two groups interpreted a trend of change over time(Ftime=3.542,Ptime=0.013),the Charnley hip joint function score of the two groups was elevated by the time extension(P＜0.05),and there was an interaction effect between grouping and time(Finteraction=4.027,Pinteraction=0.005).There was no statistically significant difference in the incidence rates of superficial infection of wound,mild ectopic ossification,traumatic arthritis,and femoral head subluxation between the two groups during perioperative period and follow-up(P＞0.05).Conclusion On the basis of operative reduction therapy via Kocher-Langenbeck approach,employing preoperative 3D printing technique combined with T-plate elastic support fixation for the treatment of patients with posterior column complex acetabular fracture can shorten operative duration,reduce intraoperative bleeding volume,intraoperative blood transfusion volume,and intraoperative fluoroscopic frequency,improve fracture reduction quality,and it is helpful for functional recovery of hip joint,exerting superior effect to simple T-plate elastic support fixation therapy,with a favorable safety.关键词
