Abstract
In this research, the osteoarthritis of the hip was picked up. It compared examined the mechanical state of the hip joint of the normality person and the artificial hip joint by the total hip replacement. At the time of one foot standing position was supposed making use of photoelastic stress freezing method. The Charnrey type artificial hip joint has supplied satisfactory clinical record. However, the fact that still normality examination is advanced is present condition. In addition, 2-dimensional photoelastic method, 3-dimensional stress freezing method and the finite element method were used together, and shape was changed and was analyzed. In this report, Comparison with the mechanical stability and the singular point and the position and the normality femur of the Charnrey type artificial hip joint is reported. Similarly, the stress state which shape exerts on THR shape the using hybrid method is reported. The mechanical indicator of the research and development of the total hip replacement is described.
