Abstract:

BACKGROUND: The current studies on biomaterial science of artificial femoral head have obtained remarkable results, but there are still some problems.
OBJECTIVE: To investigate the progress in material characteristics and application of artificial femoral head.
METHODS: A computer search of VIP database was done for articles about biomechanics of artificial femoral head with the keywords of “artificial femoral head, progress, clinical application”. Articles published recently or in authorized journals were preferred. Finally, 18 articles were included.
RESULTS AND CONCLUSION: Artificial joints used in clinic has a history of nearly a hundred years, and the relevant studies about materials and designs have made a great progress. A variety of artificial bone materials are expected to become the ideal orthopedic implants because of their appropriate pore structure, surface morphology, physical and chemical properties, good biocompatibility and cytotoxicity requirements. With the development of composite materials and improvement of production process, various biomedical materials with biological activity which have similar structure and properties to human tissues have been obtained as bone substitute materials, which brings a new hope for the development of artificial prostheses and treatment of bone defects.
