Influence of direct currents on bone vascular supply.
Electrical stimulation with a DC of 5 microA was found to result in macromolecular leakages in the microcirculation of rabbit metaphyseal bone. The blood flow rate of living bone did not change during 2.5 hours of electrical stimulation. Over a follow-up time of up to 11 weeks it was observed that vessels close to bone borders increased in size and that the number of bone capillaries increased, simultaneous with an increase in bone formation.
