Characteristics and application of bioabsorbable materials in orthopedics / 中国组织工程研究

ABSTRACT

BACKGROUND: Bioabsorbable materials have shown obvious advantages in clinical application for more than ten years, and have been widely used in many biomedical fields. OBJECTIVE: To review characteristics of bioabsorbable materials and their application in orthopedics. METHODS: The articles published in Wanfang, CNKI, VIP, and PubMed databases were searched by computer. The key words were “bioabsorbable materials, bioabsorbable metal materials, bioabsorbable inorganic materials, polymer materials, biocomposites” in Chinese, and “bioabsorbable/bioabsorbable material, metal material, polymer material, biocomposites” in English. RESULTS AND CONCLUSION: Absorbable metal materials have good mechanical properties. The corrosion mechanism of polymer materials is clear, which can predict the corrosion behavior and corrosion rate in vivo and in vitro, but its load-bearing performance is not as good as that of absorbable metal materials. After certain treatment, bioceramics have good biocompatibility, bone conductivity and osseointegration, but they are brittle and difficult to be formed. Biocomposites have the properties of component materials, and can also obtain new properties that single component materials do not have, so it has a wide application prospect.
