Parametrised Design of a Cutting Device Used for High Tibial Osteotomy

Abstract

In this paper we present a design method for a modular device used in different types of HIGH TIBIAL OSTEOTOMY surgical procedures. The requirements, necessities and functions of this modular device are presented in the first part of the article. An important aspect is the fact that the device must be designed in a manner which permit to use it for all types of HIGH TIBIAL OSTEOTOMY: opening wedge osteotomies, closing wedge osteotomies, medial osteotomies, lateral osteotomies, uniplanar osteotomies or biplanar osteotomies. This fact is possible using modular elements for the main parts of the devices. The researches could be the starting point for others researches regarding the appropriate materials and the possibility to execution customized several parts of the modular device using Additive Manufacturing facilities.

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

“…The computer-assisted 3D human bones modelling is a very frequent method while elaborating biomechanical and bioengineering researches [1][2][3][4][5][6][7]. Developing the 3D models for the human lower limb assure good premises regarding the comprehension of the shape and kinematics of these complex geometric structures, biomechanical analyses of the human 3D foot assembly, for healthy subjects and for pathological conditions as well, alongside with virtual surgeries simulations [4][5][6][7].…”

These specific methods allow elaborating studies and further design of specialized devices, used within surgeries [1][2][3]8]. The present paper fits within this context, being focused on the human femur 3D modelling.…”
