摘要目的 介绍使用HTML和虚拟现实建模语言(VRML)建立通过Web远程访问的髋臼骨折Letournel-Judet分类三维数字化浏览. 方法 首先,根据髋臼骨折Letounel-Judet分型,将重建的1例女性志愿者髋部骨骼模型通过Mimics软件的仿真模块切割模拟每一种骨折类型,将每一种骨折类型的骨折块以虚拟现实建模语言的格式.wrl导出.其次,编辑html网页,为每个骨折块建一个主菜单,每个主菜单设立调整透明度(透明、恢复、隐藏和显示)的子菜单.最后,编辑VRML文件,基于JavaScript语言建立 HTML与 VRML的通迅,实现各种骨折类型骨折块不同透明度的任意组合显示.结果 建立了髋臼骨折Letournel-Judet三维数字化分类系统(它分为5个部分),可以方便的通过远程网络访问.结论 该方法可以方便地应用于临床,提供对髋臼骨折的诊断与分析功能,使临床医生在极短的时间内可以对各类骨折的发生状况做出正确诊断.

abstractsObjective To establish a 3D atlas of Letournel-Judet classifications of acetabular fractures which provides remote access on the web through hypertext markup language (HTML) and virtual reality modeling language (VRML) for efficient remote diagnosis. Methods Firstly,different Letournel-Judet classifications of acetabular fracture were simulated based on 3D reconstruction models of healthy volunteers via Mimics software.The files of VRML format were exported after geometry modeling.Secondly,The.wrl files were edited by adding nodes of Sensor,Route,and Script to the files to make the static scene respond to users' interaction.Finally,the homepage of 3D atlas was established with the Dreamweaver software.Results The 3D atlas of Letournel-Judet classifications of acetabular fractures was established which can be accessed online.These virtual worlds can be browsed via the Internet and hyperlinked with the World Wide Web. Conclusion The 3D atlas of Letournel-Judet classifications of acetabular fractures can be easily and convenicntly used by surgeons for consultation in clinical diagnosis of an acetabular fracture.
