Abstract:

BACKGROUND: With the continuous improvement of modern technology and medical level, although there are many ways to treat infectious bone defects, there is a lack of a viable early treatment regimen that combines anti-inflammatory, fracture healing, and biodegradable therapies, for the purpose of primary
treatment measures. This is also the goal and motivation of future medical workers.
OBJECTIVE: To investigate the application and prospect of bone tissue engineering in the treatment of infectious bone defects.
METHODS: PubMed and MEDLINE database, WanFang, CNKI, VIP and CBM database were searched from 2013 to 2019 for relevant domestic and foreign literatures, including: (1) clinical application and research literature of local antibiotics; (2) experimental study on sustained release system (DDS) for the treatment of bone infection; (3) clinical and experimental literature on biological scaffold materials in large bone defects; (4) application and progress of bone tissue engineering in the repair of infectious bone defects; (5) literature on 3D printing technology. A total of 60 literature analyses and summaries were included.
RESULTS AND CONCLUSION: (1) The local use of antibiotics at bone infection site was effective. (2) Bone tissue engineering had a great development prospect and potential in inducing bone regeneration to repair bone defects, which also pointed out a new way for orthopedic surgeons to treat infectious bone defects in the future, and gave new hope to patients and their families. The breakthrough and challenge of this technology is to explore the most suitable high-quality cells. (3) To explore the perfect combination of bone tissue engineering technology, antimicrobial agents and absorbable biomaterials for the treatment of infectious bone defects with new technologies is a new development direction of the orthopedic clinical treatment for infectious bone defect in the future.
