Abstract:

BACKGROUND: Total hip surface replacement can maintain the original mechanical properties of hip joints as much as possible, the stability and activity of the joint after replacement are good, and no apparent age limitations are found.
OBJECTIVE: To investigate the artificial hip prosthesis in the treatment of sports hip injuries, the materials and methods of hip prosthesis.
METHODS: A computer-based retrieval of PubMed database and Chinese CNKI database from January 1998 to October 2011 was conducted for documents regarding the biomaterials and tissue engineered hip joints, with the key words of "hip joint injury, artificial hip joint, hip replacement, hip resurfacing arthroplasty" in both English and Chinese. Eventually 41 papers met the inclusive criteria.
RESULTS AND CONCLUSION: Severe hip joint sports injuries should be treated with artificial hip joint replacement, to restore the patient's life skills, and even certain athletic ability. Currently, prosthesis material is a key factor in the hip replacement treatment, including metals, ceramics, polymers and new bone cement, each has their advantages and disadvantages. Due to long period of follow-up and clinical observations, the efficacy of various materials needs further study. Computer-based three-dimensional finite element analysis for simulation of the hip is a research focus, this means is a combination of the sports biomechanics and the materials science. Research and development of new materials are essential for the manufacture of artificial hip prosthesis in tissue engineering, and for repair and reconstruction of hip joints.
