Deformačně napěťová analýza proximálního femuru s dříkem endoprotézy a zlomeninou / Stress analysis of proximal femur with the stem of the prosthesis and the fracture

This work is focused on a solving of problems regarding a total hip replacement with a fractured femur. The fracture is located in the distal end of the total joint replacement stem and the fracture is spreading in the proximal direction on the boundary of the bone and cement. A proximal part of femur is reinforced by fixing tape. There is also briefly described how computer models were carried out. Furthermore a stress - strain analysis of solved system has been performed in this work. The solution was realized using the finite element method in computational program ANSYS Workbench. Different variants with change of a fracture range and number of fixing tapes were considered during the solving. Stress - strain analysis shows that due a application of fourth fixing tape occurs lowering of main stresses values in the femur in fracture region. Simultaneously occurs a reduction of Equivalent stress values on a distal part of stem.
