Biomechanical properties of hip implant with ceramics coating

DOI: 10.7862/rm.2016.6

Abstract

In this paper the results of investigations of biomechanical properties of transplantation of hip bone with ceramic coating are presented. The finite element analysis of the stress-strain state of the femur bone after hip replacement surgery and full recovery period are carried out. A finite element model of the femur bone is obtained on the basis of tomographic data of 36 years old male patient. A transplant stem with ceramic coating based on A400 lateralized specification was analyzed. Stresses in the intact femur and femur after arthroplasty were determined. The effect of the reduction of bone density as the result of removal of normal stresses by an implant were analyzed. The study serves as a biomechanical basis for development of artificial prostheses and for clinical hip joint replacements.
