A Study on the Prediction of Bone Remodeling of Plated-Human Femur using 3-Dimensional Finite Element Method

The stress distribution of bone is altered by the rigid bone plate, sometimes resulting in unfavorable osteoporosis. The rigidity and the biocompatibility are important factors for the design of prosthesis. However, it is also necessary to consider the effect on the bone remodeling. In this paper, it is attempted to establish an approximate and simple method to predict the trend of the configuration of surface bone remodeling for the case of a bone plate using stress analysis. Thus, three dimensional finite element model of plated-human femur is generated and simulated. In addition. the stress difference method (SDM) is introduced and attempted to demonstrate the configuration of surface bone remodeling of the plated-human femur. The results are compared with those of invivo tests and the feasibility of the stress difference method is discussed.
