文题释义:

生物可降解:指材料在生物体内通过溶解、酶解、细胞吞噬等作用,在组织长入的过程中不断从体内排出,修复后的组织完全替代置入材料的位置,而材料在体内不存在残留的性质。
生物可吸收支架:支架材料经常被用于外科手术中,例如提供支撑的血管支架、肠道支架,另外还包括作为营养物质载体并提供一定的尺寸结构的人工骨支架、人工器官支架等。生物可吸收支架是用可溶解在人体内的材料制成,放入体内后,可被人体吸收。

 

背景:由于自体骨和异体骨移植治疗骨缺损存在许多不可避免的问题,因此生物可降解吸收材料的应用是目前研究的重点。
目的:评价几种骨修复材料的生物性能和置入后对骨缺损修复的影响。
方法:应用计算机检索1994至2015年PubMed数据及CNKI中国期刊全文数据库,英文检索词为“bone defect,biodegradable material,bone graft”,中文检索词为“骨缺损,骨移植,生物降解可吸收材料”。
结果与结论:生物可降解吸收材料主要包括天然高分子材料、人工合成高分子材料及生物无机材料。生物降解可吸收材料具有良好的生物相容性,置入后可诱导骨缺损区新骨长入,形成骨性结合,在骨修复方面已显示了明显优势,多种材料复合可以提高骨缺损修复的效果,是骨修复替代材料的发展趋势。

Abstract:

BACKGROUND: Because there are many inevitable problems in autologous or allogeneic bone grafting for treatment of bone defects, the application of biodegradable absorbable material is the focus of current research.
OBJECTIVE: To evaluate the biological properties of several kinds of bone repair materials and their influence on bone defect repair after implantation.
METHODS: PubMed and CNKI databases were retrieved for articles published from 1994 to 2015 by computer. The keywords were “bone defect, biodegradable material, bone graft” in English and Chinese, respectively. 
RESULTS AND CONCLUSION: Biodegradable absorbable materials mainly include natural polymer materials, synthetic polymer materials and bio-inorganic materials. Biodegradable absorbable materials have good biocompatibility, and can induce new bone ingrowth after implantation to form good osteo-integration. It has shown a clear advantage in bone repair. A variety of materials combined together can promote the repair of bone defects, which is the development trend of alternative materials for bone repair.
