Analysis of the current distribution in bone produced by pulsed electro-magnetic field stimulation of bone.
Pulsed electromagnetic stimulation is being increasingly used by orthopaedic surgeons to treat non-unions and congenital pseudoarthrosis. In this paper a theoretical model is developed to analyze the distribution of induced current in bone due to a pulsed electromagnetic field, produced by a pair of Helmholtz coils. The result shows that the induced current density is dependent of the electrical properties of bone, geometry of the coils and their location.
