摘　　要：目的:介绍接骨钢板的材料学特征及其临床应用现状。方法:由第一作者检索PubMed数据库(http://www.ncbi.nlm.nih.gov/)、中国知网数据库(http://www.cnki.net/)及万方数据库(http://www.wanfangdata.com.cn)2000/2009收录的有关接骨钢板材料学特征及临床应用的文章,检索关键词为"接骨钢板,材料学特征,生物相容性,临床应用"。纳入论点论据可靠、主题与此课题联系紧密的试验文章,排除缺乏原创性的文章。共纳入25篇文献,从接骨钢板的材料学特征、临床应用及其优缺点方面加以整理和分析。结果:从接骨钢板的材料学特征来看,应使其弹性模量接近骨骼,以减少应力遮挡效应。在临床应用中应注意生物固定与机械固定相结合,不断改进钢板结构,减少钢板与骨骼接触面积,以降低或防止局部形成骨质疏松。结论:目前临床上应用的接骨板材料主要包括不锈钢、钴合金及钛合金,各有其优缺点,其中医用钛合金是金属中最理想的体内置入材料。在临床应用方面微创内固定钢板为骨折后运动功能的早日恢复提供了有力的技术保障,有着广阔的应用前景。OBJECTIVE：To introduce material science characteristics and clinical application of bone plate.METHODS：The first author retrieved PubMed Database（http：//www.ncbi.nlm.nih.gov/）,China National Knowledge Infrastructure（http：//www.cnki.net/）and Wanfang Database（http：//www.wanfangdata.com.cn）for articles addressing material science characteristics and clinical application of bone plate published from 2000 to 2009.The Keywords included ＂bone plate,material science characteristics,biocompatibility,clinical application＂.Testing articles with reliable argument and evidence as well as close topic were included,and simultaneously,non-original articles were excluded.Ultimately,25 articles were included.We arranged and analyzed material science characteristics,clinical application,advantages and disadvantages of bone plate.RESULTS：From the material science characteristics,the elastic modulus of bone plate should be close to skeleton so as to reduce stress occlusion effects.In clinical application,we should pad attention to the bonding of biological fixation and mechanical fixation to improve plate structure,resulting in decrease in contacting area of plate and skeleton to diminish or prevent osteoporosis in local regions.CONCLUSION：Presently,bone plate materials mainly contain stainless steel,cobalt alloy and titanium alloy in clinic with their advantages and disadvantages.Among them,medical titanium alloy is an ideal in vivo implant.In clinical application,less invasive stabilization plate provides a powerful technique security for early recovery of motor function following fracture,and shows a spacious application prospect.
