3D打印结合桥接固定系统进行有限元分析在治疗粉碎性复杂髋臼骨折中的应用

Application of 3D printing combined with bridge fixation system for finite element analysis in treatment of patients with comminuted and complex acetabular fractures

摘要

摘要:
目的观察3D打印结合桥接固定系统进行有限元分析在治疗粉碎性复杂髋臼骨折中的效果。
方法选取112例粉碎性复杂髋臼骨折患者，随机分为观察组和对照组，每组56例。对照组采取传统钢板内固定治疗，观察组采取3D打印结合桥接固定系统进行有限元分析。比较2组术后恢复情况、复位满意率、Harris评分、并发症发生率。
结果观察组住院时间、骨折愈合时间短于对照组，差异有统计学意义(P < 0.05)。观察组复位满意率为83.93%，高于对照组的66.07%，差异有统计学意义(P < 0.05)。观察组术后3、6个月Harris评分高于对照组，差异有统计学意义(P < 0.05)。观察组并发症发生率为3.57%，低于对照组的14.28%，差异有统计学意义(P < 0.05)。
结论 3D打印结合桥接固定系统进行有限元分析治疗粉碎性复杂髋臼骨折的效果显著，可获得满意的复位与固定效果，减少术后并发症，促进髋关节功能恢复。

Abstract:
Objective To observe the effect of 3D printing combined with bridge fixation system for finite element analysis in treatment of patients with comminuted and complex acetabular fractures.
Methods A total of 112 patients with comminuted and complex acetabular fractures were selected and randomly divided into observation group and control group, with 56 cases in each group. The control group was treated by conventional internal fixation with steel plate, while the observation group was treated by 3D printing combined with bridge fixation system for finite element analysis. The postoperative recovery status, satisfaction degree of restoration, Harris score and incidence of complications were compared between the two groups.
Results The hospital stay and fracture healing time in the observation group were significantly shorter than those in the control group (P < 0.05). The satisfaction degree of restoration in the observation group was 83.93%, which was significantly higher than 66.07% in the control group (P < 0.05). The Harris scores at 3 and 6 months after operation in the observation group were significantly higher than those in the control group (P < 0.05). The incidence of complications in the observation group was 3.57%, which was significantly lower than 14.28% inthe control group (P < 0.05).
Conclusion The 3D printing combined with bridge fixation system for finite element analysis is effective in treatment of patients with comminuted and complex acetabular fractures, which can obtain satisfactory restoration and fixation effects, reduce postoperative complications, and improve recovery of hip function.
