Generalized Modeling of the Human Lower Limb Assembly

Abstract

The main reason for creating a generalized assembly of the main bones of the lower human member is to create the premises of realizing a biomechanic assisted study which could be used for the study of the high range of varieties of pathologies that exist at this level. Starting from 3D CAD models of the main bones of the lower human member, which were realized in previous researches, in this study a generalized assembly system was developed, system in which are highlighted both the situation of an healthy subject and the situation of the situation of a subject affected by axial deviations. In order to achieve these purpose reference systems were created, systems that are in accordance with the mechanical axes and the anatomic axes of the lower member, which were later generally assembled in a manner that provides an easy customization option

CAD modelling of the human femur taking into account the structure of the bone

“…The main fact that must be highlighted from of our previously made brief study is the high complexity of the bone structure. In order to accomplish the goal to model this structure, we applied the constructive-anatomical entity method [18,[21][22][23]. This specific method assumes dividing the main structure into several separate entities, which are then assembled as convenient for the 3D designer.…”
