Dichas variables pueden ser internas “inherentes al paciente” (morfología cérvico-diafisiaria, deformidades de raquis, etc.), o bien externas, ajenas al paciente (ángulo de abducción, espesor, material y dimensiones de la cabeza femoral, posicionamiento del centro de rotación de la cadera, etc.). Para poder validar esta metodología se han llevado a cabo 1.008 simulaciones (en grupos de 504) por elementos finitos sobre insertos de polietileno de ultra alto peso molecular, y de las que se han extraído 2.016 valores de tensiones de Von Mises e Intensidad de Tensión como indicadores del riesgo de desgaste y posterior fracaso protésico.

To assess and predict, from a theoretical viewpoint, the risk of wear with two types of polyethylene liners, cemented and uncemented, a simulation using the finite element (FE) method was carried out. The risk of wear was analyzed according to different variables: the polyethylene acetabular component’s position with respect to the center of rotation of the hip; the thickness of the polyethylene insert; the material of the femoral head; and the relationship of the cervical–diaphyseal morphology of the proximal end of the femur to the restoration of the femoral offset. In all 72 simulations studied, a difference was observed in favour of a cemented solution with respect to the ...

This becomes more relevant with increased wear risk and its consequences such as osteolysis. In addition, osteolysis has been described in cemented and uncemented acetabular implants, and nowadays, controversy remains as to whether or not to cement the acetabular component. A personalized theoretical study was carried out to investigate which parameters have an influence on wear risk and to determine the best fixation method. Liner wear risk was assessed for two different types of fixation (cemented vs uncemented) through Finite Elements Analysis (FEA). The intraoperative variables used to determine the wear risk (cervical-diaphyseal angle, Center of Rotation positioning -COR-, head material, head size, and liner thickness) are vital parameters in surgical planning. Two types of tridimensional liner models of Ultra High Molecular Weight Polyethene (UHMWPE) were simulated through finite element analysi...

El sistema tiene dos aplicaciones bien diferenciadas que son analizadas en este trabajo. La primera es el refuerzo de las piezas que han sufrido procesos patologicos centrados en la merma de resistencia y rigidez, y la segunda consiste en la recuperacion o consolidacion de los apoyos de las piezas que han perdido la estabilidad necesaria como consecuencia de una degradacion intensiva de uno de los extremos. El estudio se ha desarrollado en dos fases. La primera ha consistido en el estudio previo de soluciones propuestas mediante el analisis por el metodo de los elementos finitos, utilizando el programa informatico COSMOSWORKS.

The system has two differentiated applications affluent that are analyzed in this work. First it is the reinforcement of the pieces that have degradation in lost resistance and rigidity, and second consists of the recovery or consolidation of the supports of the pieces that are lost the necessary stability as a result of an intensive degradation. The study has been developed in two phases. First it has consisted of the previous study of propose solutions by means of the analysis of the finite elements method (FEM), using COSMOSWorks. This phase has served to orient the second experimental phase of verification. The second phase is oriented to group the test in laboratory of 45 different type and origen pieces: 15 pieces of great squareness of laminated wood, 15 sawn timber pieces and 15 pieces of ancient buildings. Each group of 15 pieces subdivided itself in 3 sub-groups of 5 pieces with the following criterion. The first sub-group, served as witness of the pieces without no type of reinforcement or prothesis. The other two remaining sub-groups for the study of the reinforcement and the prothesis respectively. Finally, it has been come to make a real experience in work, in a wood floor slab of an ancient building (XIX century) in the historic town of Madrid. Tests of field by means of the application the reinforcements were executed on 32 lumber with different lengths, obtaining coincident results with the experiences of the laboratory. The conclusion of this system displays a simple application in the work, with a reasonable cost and mechanical results of the reinforcements and the prothesis of high effectiveness. The increase of the stiffness is 200% and the increase of the load capacity in the reinforced pieces is 150%. The recovery of the supports by means of the metallic prothesis reaches an acceptable load capacity. The use of FEM has been of great value and effectiveness for the project of the reinforcement solutions.
