摘要
背景:三维重建技术能够提供人体内部结构的数字化三维模型,并利用相关软件在模型上进行手术设计和生物力学分析,为椎弓根螺钉的安全有效置入提供可靠数据。目的:综述CT三维重建在颈椎弓根测量中的应用。方法:应用计算机检索1990/2011PubMed数据库、维普数据库及万方数据库中有关CT三维重建在颈椎弓根测量中应用的文献,英文检索词为"thre edimensional reformation sofmulti-slicespiral CT;cervical pedicle";中文检索词为"颈椎弓根;三维CT;计算机辅助设计;脊柱外科;数字骨科;医学图像"。结果与结论:应用CT三维重建技术可以获得清晰颈椎三维图像。颈椎椎弓根螺钉置入技术因颈椎椎弓根变异较大,临近解剖结构复杂,目前国内仅少数医院得以成功开展。而利用三维CT重建测量颈椎弓根可以模拟椎弓根螺钉置入技术,能够真实准确地观察和测量椎弓根螺钉在椎体内的情况,获取个体化解剖数据,为临床应用椎弓根螺钉置入技术提供指导。
BACKGROUND:Three-dimensional reconstruction technique can provide digital three-dimensional model of human internal structure.Surgery design and biomechanical analysis were conducted on the model using relevant software,which can provide reliable data for safe effective implantation of pedicle screw.OBJECTIVE:To review the application of CT three-dimensional reconstruction in cervical pedicle measurement.METHODS:We retrieved PubMed Database,Vip Database and Wanfang Database for literature regarding the application of CT three-dimensional reconstruction in cervical pedicle measurement published from 1990 to 2011.The English were "three dimensional reformations of multi-slice spiral CT,cervical pedicle".The Chinese key words were "cervical pedicle,three-dimensional CT,computer-aided design,spinal surgery,digital orthopedics,medical image". RESULTS AND CONCLUSION:Using CT three-dimensional reconstruction technique could obtain clear three-dimensional image of cervical vertebra.Due to the great variation of cervical pedicle and complicated anatomic structure,cervical pedicle screw implantation has been used in a few hospitals in China.However,three-dimensional CT reconstruction for measuring cervical pedicle simulated pedicle screw implantation,exactly observed and measured pedicle screw conditions in vivo,and obtained individual anatomic data,which provided guidance for clinical application of pedicle screw implantation.
