CREATION OF A BIOMECHANICAL MODEL OF THE FOOT AND ANKLE JOINT COMPLEX
The use of tridimensional biomechanical models allows the simulation of articular movements and also stress and strenght analisis on the tissues. The foot and ankle are a stable base of support for the body, provides shock absorption and propulsion of the body during gait, therefore, the creation of a model for this complex joint is indeed needed. . Objective: This study aims to develop a 3D biomechanical model of the joint complex of the foot and ankle. Orientation and relation between bones and ligaments will be demostrated and may be used in future biomechanical simulations through the model. Methods: This mod-el is formed by skin and bones from the joint complex foot and ankle, besides the ligaments of the subtalar and talocrural joints. In order to be built, images of cadavers were used from the Visible Human Project®. First, the bone structures were marked by dots and then imported by the software Solidworks®. The bone accident referring to the origin and insertion of each ligament was marked on the 3D geometry and those dots were connected with strips, with its characteristical disposition and thickness, forming one by one the ligaments. Results: Buiding the model makes it possible that an optimized view of bones and ligaments be simultaneously made, presenting an advantage ahead of the models built from CT scans and MRI. The great anatomic representativity of the model may be useful in cirurgic simulations, injury treat-ment, anatomy teaching and radiology, in the ergonomic and sportive areas, besides the pro-duction and perfecting of orthesis, protesis and shoes. Furthermore, bone accidents are rec-ognizable (the articular space and the morphology and disposition of the 3D ligaments) and it showcases an advance in the sense of having more precise ligaments, which connect bones and aid the stability of the joint and the anatomic movement control. Conclusion: The model built in this study can be usefull in many aspects of the healthy field, for example, in the crea-tion of orthesis and protesis. Besides, the use of biomechanics simulation makes the ligamen-tar tension distribution analisys possible, which can be usefull in the injury prevention and treatment.
