Abstract:

OBJECTIVE: To evaluate the performance of different types of hip joint prosthesis materials, as well as biocompatibility with the host after implanted in vivo, to provide reference for clinical applications.
METHODS: Using “hip joint, prosthesis, materials, biocompatibility, clinical application” in Chinese and in English as the key words, a computer retrieval was performed for articles published between January 2000 and July 2010. Articles related to the biocompatibility of biological materials to the host were included, duplicated research or Meta analysis were excluded. Totally 30 articles focused on the type, performance and clinical application of hip replacement prosthesis materials.
RESULTS: Metal materials play an important role in hip prosthesis, combination of metal joint head and ultra-high molecular weight polyethylene acetabular is the most widely used in hip joint replacement, but there is poor resistance to abrasion, poor lubrication, and poor corrosive resistance. As for ceramic-type hip joint prosthesis, ceramics have a strong wear resistance, low toxicity and bone integration effect, but their fragility still needs to solve.
CONCLUSION: The ideal implant materials should have good biocompatibility, corrosion resistance, wear resistance, fatigue resistance, strong strength and elastic modulus closer to the characteristics of human cortical bone, which need to be further developed.
