Three-dimensional finite element stress analyses of the femur with prosthesis hip stem were performed for two cases, one male and one female, using ideally bonded cemented titanium prostheses. Computed tomography data files were used to derive the three-dimensional femur geometry and material properties for each cortical bone element. The maximum shear stress (4.7 MPa) in the cement was greater then the maximum tensile stress and occurred at the cement-bone interface. The tensile stresses in the cement were less then the fatigue strength of the cement. The stress patterns were quite similar for the two cases.

A data analysis program was developed to processes computed tomography data files of a proximal femur into a finite element model file with prosthesis. The program utilizes Microsoft Excel, it Visual Basic Modules, Math Soft Mathcad, dynamic data exchange, custom menus and user input boxes to make the user interface as efficient as possible.
