非融合性棘突间固定器在下腰痛治疗中的应用

目的:了解非融合性棘突间固定器的应用研究进展。资料来源:检索Medline 1966-01/2004-10和Ovid数据库2003-01/2007-06与非融合性棘突间固定器及下腰痛相关的文章,检索词"inter-spinous,low back pain",并限定文章语言种类为英文。资料选择:阅读全部文章的文题和大部分文章的摘要。选择文献所述内容与非融合性棘突间固定器类型、非融合性棘突间固定器减轻疼痛的机制相关的文献。排除重复性研究和Meta分析类文章。资料提炼:共得到符合纳入条件的文献351篇,排除322篇。选择其中29篇进行分析,排除的文章为重复性研究。资料综合:非融合性棘突间固定器改善下腰痛的机制为对腰椎退变性下腰痛的生物力学环境的影响,如对椎间盘纤维环后缘的负荷减轻作用、对椎间孔的撑开等。目前应用的非融合性棘突间固定器,如X-STOP,Wallis,DIAM,都是相对早期开发并经过测试的,所以其有效性,有用性和危险性及引发并发症情况正通过和即将通过临床试验得到证实。结论:非融合性棘突间固定器治疗腰椎退变性下腰痛可以取得良好的临床效果,且可避免融合技术的并发症。

Application of non-fusion inter-spinous stabilization devices in the treatment of low back pain

OBJECTIVE: To understand the research on the development and application of non-fusion inter-spinous stabilization devices.DATA SOURCES: Using the key terms of "inter-spinous and low back pain", relevant articles on non-fusion inter-spinous stabilization devices and low back pain in English were retrieved from Medline between January 1966 and October 2004 and the Ovid database between January 2003 and June 2007.STUDY SELECTION: Titles and most abstracts of all articles on the types of non-fusion inter-spinous stabilization devices and action mechanisms of non-fusion inter-spinous stabilization devices were selected. Duplicated researches and meta analytic papers were excluded.DATA EXTRACTION: A total of 351 articles met the inclusion criteria and 322 were excluded. Among them, 29 papers were analyzed. The major exclusion factor was duplicate studies.DATA SYNTHESIS: Non-fusion inter-spinous stabilization devices can improve mechanism of low back pain and cause certain effects on the biodynamic environment of degenerative lumbar vertebrae, such as relieving loading of the posterior border of the anulus fibrosus of the intervertebral disc and opening the intervertebral foramen. At present,non-fusion inter-spinous stabilization devices, such as X-STOP, Wallis and DLAM, have been tested for a long time;therefore, the effects of their effectiveness, utility and risk of complications will be proved by clinical experiments as soon as possible.CONCLUSION: Non-fusion inter-spinous stabilization devices have good effects on the treatment of degenerative low back pain originating in the anulus fibrosus of the intervertebral disc and can reduce complications caused by the fusion technique.
