Histomorphologic evidence of fracture healing after direct electrical stimulation in dogs.
A histomorphologic study was done at intervals up to 10 days after causing a fracture in both hindleg tibiae in dogs and giving direct electrical stimulation in one tibia, the other being used as control (20 microns ampere of direct current were passed in 28 limbs and the current was maintained with the help of a simple regulator developed by the authors). The radiologic and histomorphologic study showed definite evidence of early start and completion of healing processes in the electrically stimulated hindlegs. Negative potentials induced at the fracture sites appeared to be the cause of improved healing. The incidence of infection and focal necrosis at the anode was minimal in this experiment.
