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.
Highlights
In this research we design a specialized modular device used for High Tibial Osteotomy (HTO), a surgical intervention which corrects the axial deviations of the human’s leg.The leg’s mechanical axis (Figure 1.) is a line which unites three key elements: the middle of the hip’s articulation, the middle of the knee’s joint and the middle of the ankle’s articulation

Summary
In this research we design a specialized modular device used for High Tibial Osteotomy (HTO), a surgical intervention which corrects the axial deviations of the human’s leg. The leg’s mechanical axis (Figure 1.) is a line which unites three key elements: the middle of the hip’s articulation, the middle of the knee’s joint and the middle of the ankle’s articulation. This line is comprised from 2 segments corresponding of the mains bones of the leg: tibia and femur. The cartilage’s wear is in general unicompartimental This wear provokes an abnormal knee load which inevitably leads to an axial deviation. In order to obtain a precise realignment of the bone, accurate geometrical and dimensional planning is required For this purpose, we designed a modular specialized device which increase the accuracy and the precision of this surgical procedure
