| Abstract text: | According to a study carried out at the County Clinical Emergency Hospital in Arad, over 40% of the accidents resulting in femur fracture take place on roads and highways. This work briefly presents these results, and on the basis of bibliographical data regarding the mechanical behavior of bones and the classification of femur fractures occurring in expert literature, a simulation program of these fractures in the case of car accidents. The aim of the program is to determine the pressure at which the femur is fractured in different conditions of mass and speed of the vehicle, braking distance, age of the victim, femur size, etc. The use of this program represents a simulation method, as an alternative to direct expertise at the site. Following a study carried out on 4-year period at the orthopedics section of the County Clinical Emergency Hospital in Arad, it was found that, out of a number of 120 patients with femur fractures. The first step in developing our concept was to observe de dynamic and the action of the osseous/bone tissue under physical stress. Inside of the Anatomy Lab of „Vasile Goldis” Western University we have osseous pieces. Before and after the preparation protocol the osseous pieces had been measured. The second step was the implementation in the programming language of the formulas. Depending on the initial data, if, in consequence of the impact, pressure exceeds the critical threshold, the program establishes whether the femur remains intact or a fracture will be produced at its level. The program also makes it possible to establish the type of fracture. The third step was the graphic representation of the experiment. To this effect we chose to employ 3D graphics, namely the most powerful instrument in the field, 3D Studio Max. |
