Drilling in Bone: Modeling Heat Generation & Temperature Distribution by Using HBIM

Abstract

Drilling of bone is an essential part of internal fixation in orthopedic surgery. In case of fracture of human bones, the best way to better and faster knitting is when it is fixed by drilling and setting the immobilization plates by screws. Because of the drilling process, the surrounding bone tissue is heated and if temperature around the drilled bone hole exceeds the critical limit, this may result in thermal necrosis. This work studies and models heat generation and temperature distribution for the prediction of thermal necrosis and the relationships between different parameters of drilling for the optimization of the drilling process in bone.
Considering the vast no. of variables involved in the process it is almost impossible to conclude the results precisely, but taking into account past researches a primary generalization of the relationship between parameters is presented.
