Abstract
The paper presents the results of a preliminary study on the structural analysis of the pelvic girdle, comparing results for the analysis performed before and after the hip replacement procedure with taking into account changes in the mechanical properties of the articular cartilage of the joint. Basic anatomy and biomechanics of the hip joint is introduced. The mechanical analysis of the hip joint model in each case is conducted. Final results of analysis are presented. The numerical model of the tested objects was made on the basis of CT and CAD modeling. Hip bone models were made using specialist software such as Materialise Mimics. The model is made in the program was then exported to a data exchange file in order to obtain the editable CAD files. Thus obtained models were the starting point for the implementation of the numerical model of personalized hip replacement. Numerical models of bone and implant were performed in Solidworks environment.
Mechanical analysis was carried out using finite element analysis. During performing of calculations with the use of finite element analysis other physical quantities are also being discretized: loads, tensions, restraints or other examples represented in the system with the use of continuous function. While performing the process of discretization software aims at maximally approximation of discreet and continuous form using approximation methods.
