| Sumario: | [EN] The Department of Mechanical and Materials Engineering of the University Polytechnic of Valencia has developed some efficient Finite Element codes in Matlab based on the use of geometry independent Cartesian grids (FEAVox). One of its main numerical features is that the code is able to perform ‘patient specific’ analyzes from medical images. This project is focused on using FEAVox in order to simulate the effect of future surgical operations involving prosthetic implants in a ‘patient specific’ framework, with the main objective of estimating the quality of the connection between bone and object, once it is placed in the patient. This process aims to provide knowledge of the adequacy of the implant beforehand, bearing in mind the needs and the success of future surgical operations of the patient. FEAVox is able to create a finite elements model that represents accurately the bone features near the implant, whose position requirements involve a previous pixelization process and the development of a new Matlab program that allows the user to precisely move and position the object. The use of the techniques shown in this document will allow the development of a new validation process for the specific operation needs in a certain patient, based on the evaluation of changes in the natural frequencies and vibration modes according to the melding level of the bone-implant system. For this reason, a dynamic analysis code will be incorporated to FEAVox. Its results will be used as quality indicators. |
