Abstract:
Artificial hip replacement is the most universal and effective means for treating terminal stage disease of hip joint. At present, the metal, ceramic, organic polymer and composite materials used in hip prosthesis have various problems. Metal ions or particles which released from metal materials can increase the wear rate and have potential toxicity to human. Polymers results in arthroplasty failure by bone resorption with macrophages. Bioceramic has poor mechanical property, and cause bioactivity decrease at over high temperature. Accordingly, the biocompatibility of hip prosthesis materials can be enhanced by improving design and manufacturing technology, increasing abradability and mechanical property, enhancing associativity, decreasing stress shielding, which can prolong serve life of the prosthesis.
