摘要:

背景:髋部骨折的病情较复杂,临床医师选择适当治疗方案和手术入路的主要依据来源于影像学检查,常难以准确判断空间立体关系。
目的:探讨基于64排螺旋CT扫描数据对髋部骨折进行虚拟手术设计的可行性和临床应用价值。
方法:将髋部骨折患者.dicom格式CT数据导入Mimics软件,进行图像分割,建立骨折三维模型并进行虚拟复位,将.stl格式复位模型导入Imageware12.0,根据钢板放置位置选择合适长度钢板,螺钉固定。并快速成型形成实体与导航模板。
结果与结论:重建三维可视模型可准确反映出骨折特点、骨折移位方向和程度,并可进行任意旋转观察,实现了内固定手术模拟。可见术前应用计算机辅助虚拟现实手术设计可以制定合理的个体化手术方案,有很好的临床应用价值。

Abstract:

BACKGROUND: The hip fractures are difficult to treat because of its complexity. Clinicians select appropriate treatment options and surgical approaches according to imaging studies, which are difficult to accurately determine the spatial three-dimensional relationship.
OBJECTIVE: To study the feasible and clinical value of computer-assisted preoperative design for hip fractures based on 64-slice spiral CT scanning data.
METHODS: CT data in .dicom format from the patients with hip fractures were imported into Mimics. In segmentation process, the three-dimensional model of fracture was built to perform simulated reduction. The reduced model in .stl format was transferred into Imageware 12.0 to determine an appropriate dynamic hip screw in a suitable place and fixed with screw. And then using rapid prototyping, the entity and navigation template were formed.
RESULTS AND CONCLUSION: The three-dimensional reconstructed visualization model could reflect the features of fractures, and the direction and degree of fracture displacement. And the fracture models could be rotated in any direction and space for observation which could simulate the internal fixation surgery. Preoperative computer-assisted virtual reality surgery can help to make a reasonable individualized surgical option, which has good clinical value.
