ABSTRACT
BACKGROUND:There are many treatment methods for infected bone defects,but there is no first stage treatment method,which has the characteristics of sustained-release,anti-inflammation,osteogenic activity,bone conduction and degradable absorption.OBJECTIVE:To investigate the research progress of bone tissue engineering technique in the treatment of infected bone defects.METHODS:A computer-based retrieval of PubMed,WanFang and CNKI databases was conducted for the articles published from 2000 to 2016,concerning the basic and clinical research on the local application of antibiotics;basic research on infected bone defects with sustained-release of antibiotics;basic studies on the source of seed cells and the osteogenic mechanism;and scaffold materials.A total of 55 eligible articles were included for result analysis.RESULTS AND CONCLUSION:Topical application of antibiotics exhibits different effects in the treatment of osteomyelitis.The development of bone tissue engineering has brought new hope for the treatment of bone defects,and in the meanwhile,selection of excellent seed cells has become a hot and difficult research.A rational combination of antibiotics,seed cells and scaffold materials may provide a new treatment strategy for infected bone defects.
