Abstract:

OBJECTIVE: To analyze the advantage and problems of artificial hip joints made of different materials in clinical applications, and to evaluate the effects of articular surface wear on aseptic loosening.
METHODS: A computer search of relevant articles published from January 1990 to December 2009 was performed by using the keywords of “biological materials, hip, prosthesis, hip resurfacing” in Chinese and English. Repetitive studies or Meta analysis were excluded.
RESULTS: The life of artificial hip joints is closely related to the articular surface wear. The appearance of aseptic loosening is not only related to the design of prostheses, but also associated with prosthetic materials. Based on the comparison of different hip prosthesis material properties, we provide the basis for the selection of an ideal hip prosthesis material with good wear resistance and biocompatibility.
CONCLUSION: Surface modification of hip prosthesis materials and frictional behavior of human hip joint are biological hot spots in the future. The evaluation system for hip prosthesis materials is a serious problem to be solved.
