Propuesta de un nuevo diseño de órtesis post-tratamiento de pie equino varo congénito

Abstract

This research was developed with the objective of redesigning the orthosis used in the post- Ponseti treatment in children with clubfoot, with the intention of reducing the rejection to its use. Method: A research on the needs of children with congenital clubfoot was conducted to identify the disadvantages on functionality, design and adaptability of the orthosis if the splint is not used appropriately, the risk of relapse is 80 %, whereas using the splint, the risk is 4 %. A biomechanical study of a patient’s movement during the crawl was performed with and without the orthosis. Results: A 3D model of the design was developed to simulate computationally its performance under the forces generated by the babies during the kick in supine position. Finally, an experimental evaluation of the alpha prototype performance was made to determine whether it met the intended goal. Thus, the manufacturing and testing of the orthosis on virtual and in physical platform took place. Taking in account the goal of this project, it was determined that it is possible to reduce the reject to the use and therefore the formation of relapse by reducing the determinant factors of the common market splint, which promotes its incorrect use of this in the treatment. The average crawl speed is 0.48 m/s and with the splint, it decreases to 0.37 m/s. Discussion: The weight of the common market splint is 304.07 g and the weight of the one designed in the study is 209.26 g. Further biomechanical research is suggested to get conclusive results
