Effects of pulsed electromagnetic noise fields in treatment of fresh fractures in canine rabbits

Abstract

In rec~nt decades electromagnetic fields have receiveda wide attention for its accelerative effects on the healingprocess of fractured bones. In this thesis, theory and designconsiderations of electromagnetic fields are discussed. ApLllsed low-frequency electromagnetic noise field (PEMF)generator is designed. The low-frequency electromagneticnoise field (EMNF) has a 1/f shape over the frequency rangefrom 10 Hz to 1 kHz, and pulsed at a rate of 15 Hz. The EMNFis inductively coupled to the left leg of cannine rabbits,for increasing of healing mechanism in fresh fractures andhistological results of experiments are evaluated.
