Using the images from VHDS, a finite element model of the human body with an intramedular nail in the femur was prepared.
The model was exposed to a low frequency (50 Hz) electromagnetic field with the intensity of ICNIRP reference levels for the general populace.
To evaluate the influence of the implant on the current density distribution, two models were used: with the implant and without it.
The results were compared to ICNIRP basic restrictions for the general populace. From the results it can be seen that the implant significantly increases current density in the region where it is in contact with soft tissue.
