摘要
背景:生物可降解植入物不仅可重建骨缺损部位,而且随着材料的逐步降解,新生骨组织可完全替代移植材料,填充骨缺损处。目的:总结生物降解材料复合成骨因子在骨科的研究进展。方法:以"可降解材料,成骨因子,细胞活性因子,骨组织工程;Biodegradable materials,factors,cell active factor,bone tissue engineering"为检索词,应用计算机检索Pub Med、万方、CNKI数据库2000至2015年的相关文献。结果与结论:生物可降解医用高分子材料可分为天然高分子材料和人工合成可降解材料。天然高分子材料具有良好的生物相容性,但其机械强度较差;人工合成可降解材料械强度较天然高分子材料高,但容易造成局部酸性物质堆积,产生局部炎症反应。将生物可降解医用高分子材料与成骨因子复合,可提高材料的力学强度与骨诱导能力,但将其作为骨修复材料应用于临床还有很多问题需要解决。
BACKGROUND： Biodegradable implants cannot only rebuild bone defect site, moreover, with the gradual degradation of the materials, new bone tissue can completely replace the graft materials to fill bone defects. OBJECTIVE： To summarize the research progress of biodegradable materials combined with osteogenic factor in orthopedics. METHODS： We took the ＂biodegradable materials, factors, cell active factor, bone tissue engineering＂ as the search terms in Chinese and English, respectively, to retrieve the related literatures from Pub Med, Wanfang and CNKI database during 2000 to 2015 by computer. RESULTS AND CONCLUSION： Biodegradable medical polymer materials can be divided into natural polymer materials and synthetic biodegradable materials. Natural polymeric materials have good biocompatibility, but poor mechanical strength. The mechanical strength of synthetic biodegradable materials is higher than that of natural polymer materials, but the synthetic biodegradable materials are likely to cause local accumulation of acidic substances, produce local inflammation. The biodegradable medical polymer materials combined with osteogenic factor can improve the mechanical strength and osteoinductive ability of materials, but as a bone repair material, it still has many problems to be solved.
