Two-dimensional finite element method analysis of the proximal end of the femur.
The effects of differences in the models in the two dimensional analysis of the proximal end of the femur were investigated. The models were compared by the following four types of analysis: (1) the model having the same mechanical property entirely, (2) the model in which the mechanical property of the cortical bone of the diaphysis differs from that of the cancellous bone in the femoral head, (3) the model being the same as (2), except that the thin cortical bone is set around the bones other than cortical bone of the diaphysis, and (4) the model having several mechanical properties in the cancellous bones. As a result, it is evident that model formation is very important in the analysis of the locomotive organs in vivo by the finite element method. The analysis was performed by using the NASTRAN program. THe report of R. Scholten was used as a reference for the element divisions and the mechanical properties.
