A 3D evaluation of electrical variables in a thigh regarding magnetic stimulation of femoral diaphysis fractures
Abstract
The behavior of electrical variables induced in a 3D thigh geometric model with femoral diaphyseal fracture stimulated magnetically is examined. A methodology for construction of each patient thigh conformed by six scale models, including the fracture shape with blood material was developed. A pair of Helmholtz coils is added to the geometric model as a stimulation source. The stimulation signal is between 0,5 -2 mT and 5-100 Hz. The results refl ect the importance of the thigh geometries, the magnetic fi eld and intensity with the magnitude and polarity of the induced electric fi eld, and the frequency and magnetic fi eld with the induced current density. This methodology does not require additional expenses to the conventional treatment.
