MONCADA, María Elena  and  CADAVID, Héctor. A 3D evaluation of electrical variables in a thigh regarding magnetic stimulation of femoral diaphysis fractures. Rev.fac.ing.univ. Antioquia [online]. 2007, n.42, pp.120-131. ISSN 0120-6230.

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