Modular device used in the surgery of the human tibia

Abstract

Abstract. The presented article is an original contribution which implies the design of a specialized modular device used at the different surgical procedures applied at the human knee. The increasing of the precision and quality of the surgical procedures using specialized devices is an important goal both for the engineers and for the doctors. In the paper are presented some diseases which affect the human knee and also the possibilities of surgical treatment of those. The main knee pathology which was researched, regards the axial deviations of the human lower member and correction using HIGH TIBIAL OSTEOTOMY (HTO) in all possibilities: with opening wedge or closing wedge, medial or lateral, uniplanar or biplanar. The complexity of these surgical procedures from geometrical point of view opens up the possibility to increase the quality of the medical act through using specialized devices. In this regard, in the present article it is approached the design and the modelling of the modular device destined for the knee surgery using HTO techniques. The main objectives are: establishing the needs and requirements that the device should accomplish, the identification of the primary functions, the development of the implementation solutions, the synthesis of these solutions and finally the 3D design of the device using Catia V5R20.

Effectiveness Assessment of CAD Simulation in Complex Orthopedic Surgery Practices

“…Research has also developed in other directions by testing soft tissue simulations, such as in the script of Perica et al (2017), [18] but without particular results. In the work of Cofaru et al (2018) [19] the authors approach a modular device suitable for the different human knee surgery procedures built through the use of Catia V5R20, a commercial software. In the script of Gómez-Palomo et al (2020) [20] is described the case of a 26-year-old patient diagnosed with Blount disease and the implementation of relative cutting guides for the surgery with the use of the commercial software Fusion 360.…”
