[Bone healing and dynamic interferential current (DIC) (author's transl)].
The aim of this investigation was to clarify the influence of dynamic interferential current (DIC). Two sinusoidal currents of medium frequency are superimposed within the body to determine the reactive changes of bone healing after osteotomy. An osteotomy was performed on the radius and ulna of the right foreleg of 34 'black-head breeding sheep'. The radius shaft was deperiostalized and unstably fixed with a four-hole AO-plate leaving a gap of at least 1 mm width. DIC of different mA-values were not treated 24 sheep 3 times per week for 10 mins. The other 10 animals were not treated with DIC but used as control animals. The different results of our clinical, radiological, histological and chemical analyses to date indicate that callus formation is accelerated by the application of DIC. The fracture callus of treated animals is strongly mineralized.
