Abstract:

BACKGROUND: In principle, fracture treatment mainly focuses on bone remodeling from the biological and mechanical aspects to combine mechanical fixation with biological fixation as well as combine intramedullary fixation with extramedullary fixation.
OBJECTIVE: To introduce the principle development of fracture treatment and bone remodeling.
METHODS: A computer-based search of CNKI (2006-01/2011-05) and PubMed (2006-01/2011-05) for bone remodeling articles using the keywords of “bone structure, rebuild, principle” in Chinese and English, respectively.
RESULTS AND CONCLUSION: In 30 collected articles, 14 were included in result analysis. The treatment concept of fractures has been gradually changed from mechanical fixation system to biological fixation system. Fracture treatment research focuses on the balance between stable fixation and intact soft tissues, and the design of implants and instruments is significantly improved. In recent years, there are digitized virtual human technology, bio-mechanics finite element theory, trauma-control theory, pharmacological research for osteoporosis, and tissue engineering theory and technique to repair defects. In general, the concept of bone remodeling is to choose a most reasonable patient-centered way to guide and promote bone healing and functional recovery at the macro-and micro-level.
