经伤椎椎弓根置钉技术在胸腰段骨折中的应用

Application of intermediate screw technology on thoracolumbar fractures

背景:对于胸腰椎骨折,有很多固定方式,但目前经伤椎后路短节段内固定是损伤最小、费用较少,且固定牢固的固定方式。目的:系统阐述伤椎置钉技术的发展及其临床应用效果。方法:应用计算机检索1983-01/2011-06PubMed数据库、中国知网数据库中相关文章,中文检索词为"伤椎置钉,椎弓根螺钉内固定,胸腰段骨折",英文检索词为"intermediate screws,pedicular screw fixation,thoracolumbar fracture"。排除重复文献。结果与结论:共纳入48篇文献进行综述。目前,生物力学实验及临床应用结果证明,经伤椎短节段椎弓根螺钉内固定能即时复位骨折椎体,恢复椎体高度,且同传统的后路短节段内固定相比,能有效地降低内固定松动或短钉、伤椎高度再次丢失等并发症的发生率。

BACKGROUND：For thoracolumbar fractures,there are a lot of fixed ways,however,at present intermediate screws in short segment pedicular fixation isminimal damage,cost less,and fixed tightly.OBJECTIVE：To systemic illustrate the technology of intermediate screw and clinical application effect.METHODS：A computer-based online search was performed on PuMed database and CNKI database with key words of ＂Intermediate screws,pedicular screw fixation,thoracolumbar fracture＂ in English and Chinese from January 1983 to June 2011.Repeated literatures were eliminated.RESULTS AND CONCLUSION：A total of 48 articles were included to review.Biological mechanics experimental and clinical application result indicates that intermediate screws in short segment pedicular fixation can instantly reset vertebral fracture,restore vertebral body height,and compared with the traditional short segments of the posterior fixation,intermediate screws in short segment pedicular fixation can effectively reduce the incidence of complications of internal fixation loose or screw breakage,vertebral height lost again.
