Application of Advanced Design and Development Techniques in Orthopaedics

摘要

This project covers Mechanical Engineering based research directed safety systems which can be successfully implemented in the field of orthopaedics. It includes the development of tool which helps in preventing the fractures usually occur after the fixation of plates over the humerus bone. Fractures mostly occur on femur bones and humerus bones. This project mainly focuses on injury to the shaft of humerus bone. So this project mainly deals with the stress analysis of bone particularly on the humerus bone during the fixation of plate. The deflection of the bone is calculated manually and the value is compared with the ANS YS solution and the aid of rehabilitation of patients having acute pain on upper limp and vertebrae is effected by calculating the load on the spine due to plate fixation. With the help of the "laws of theoretical mechanics," the maximum bending moment is determined by using CLAPYRON'S THEOREM (THEOREM OF THREE MOMENTS). This project aims to use FEA/CT/CAD/CAM/RPT related technologies to substitute infected bone regions with the help of CT to CAD to STL manipulation. The paper focuses on new fabrication of artificial human bone in emergent situation by using RP technologies. Due to RP technologies, doctors and especially surgeons are privileged to do some things whichever the previous generations could only have imagined. However this is just a little step ahead. There are many unsolved medical problems and many expectations from RP in this field. This will help RP technologists to give their maximum, in such an important field like medicine.
