摘要
详细周密的术前计划和熟练可靠的术中定位,是人工全髋关节置换手术成功的重要保证。目前,定位系统的研究和应用已有了很大的进展。术前计划由仅仅依靠股骨和髋臼的X线平片及每个假体部件的剖面轮廓图发展到利用图像引导系统(IGS)进行“虚拟关节置换”。术中定位由单纯依靠经验目测、使用髋臼定位器发展到利用IGS进行术中导航。
The success of total hip replacement relies on detailed preoperative pla nning and reliable localization during operation.Currently,great advances have been made in the research and application of localization s ystem.The traditional preoperative planning is based on plain radiographs of the p elvis and femur as well as the profile outline of each prosthetic component.Now image-gu ided system(IGS)is used to perform virtual implantation.Surgeons used to localize during total hip replacement only wi th eyes or unreliable localization d evices,but now they begin to use imag e-guided system for surgical navigation during operation.[
