Good biomechanical property of internal fixation material has great effects on therapeutic outcomes of damaged bone. Good mechanics outcomes can be obtained by improving the shape and structure of internal fixation material.OBJECTIVE:
From the view angle of biomechanical feature of orthopedic implant internal fixation material, to analyze the correlation of shape and structure of orthopedic implant and internal fixation outcomes.METHODS:
We retrieved PubMed, Vip and Wanfang Database for articles concerning bone injury treatment and internal fixation material published from January 1990 to December 2011. The key words were “bone, fixation, shape, material”, which were searched in titles and abstracts. The articles addressing repetitive studies, common reviews or Meta analysis were excluded. A total of 156 articles were primarily obtained, and 29 articles were included according to inclusion criteria.RESULTS AND CONCLUSION:
Biomechanical property of orthopedic implants played an important inhibitory effect on bone fixation, bone blood supply, growth and regeneration of osteoblasts. Changes in material shape and structure would produce great effects on biomechanical property, and further affected therapeutic outcomes. How to use new technology to improve shape and structure of orthopedic implant material, and to perform physical modification and to reach ideal internal fixation therapeutic outcomes, has become a focused project by researchers.
