Abstract
Osteoarthritis is a progressive and irreversible condition, where there is loss of articular cartilage causing pain and in some cases deformity, especially in weight-bearing joints such as the hip joint. From the social and economic point of view the impacts are enormous, since the arthrosis reduces the quality of life of the affected patients and its treatment involves procedures with great cost. In this context, the study of three-dimensional modeling and rapid prototyping procedures are the key to the development of methodologies that help in the prevention and correction of joint disorders. In this work, mechanical analysis of the adaptive hip guide 3D (three-dimensional) printed in ABS polymer for periacetabular osteotomy surgery was developed. Firstly, tensile tests were performed to determine the mechanical properties of the 3D printed ABS polymer. To evaluate the design of the surgical guide, a computational model was made using Meshmixer. To reduce the computational cost, a simplified model of the guide was generated using Abaqus geometric tools. The finite element analysis was performed and the Tresca stress distribution was evaluated for different conditions of surgical procedure. After the analysis it is possible to verify if the surgical guide is effective in its function of assisting in periacetabular osteotomy surgery.
