ABSTRACT
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 fil bone defects.OBJECTIVE:
To summarize the research progress of biodegradable materials combined with osteogenic factor in orthopedics.METHODS:
We took the “biodegradable materials, factors, cel active factor, bone tissue engineering” as the search terms in Chinese and English, respectively, to retrieve the related literatures from PubMed, Wanfang and CNKI database during 2000 to 2015 by computer. RESULTS ANDCONCLUSION:
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 stil has many problems to be solved.
