Abstract:

BACKGROUND: Traditional reduction and external fixation techniques have a better therapeutic effect on bone crack and regulated fractures, while they are not satisfactory in the treatment of complex fractures. The current biomaterials for bone injuries become gradually mature and diversified.
OBJECTIVE: To review the material measures for treatment of bone injuries, and to classify and analyze the properties of relevant materials, especially their biocompatibility to human immune responses.
METHODS: A computer-based search of PubMed, VIP and Wanfang databases (1990/2011) was performed for artificial materials for treatment of traumatic fractures using the keywords of “bone, biological materials, biological properties” in English and Chinese. Relevant articles published recently or in authorized journals were preferred. Among 194 retrieved articles, only 24 articles were included in result analysis.
RESULTS AND CONCLUSION: Violent movement is the main factor for traumatic fractures. Bone repair and bone graft materials have been developed through a long process, and the use of materials science becomes gradually mature. Based on the selection, development and clinical application of internal fixation materials, metal implants and bone tissue engineering materials, good biocompatibility of artificial biomaterials is an essential basis for bone repair, but it is also a difficulty and challenge in the use of a variety of materials.
