[Electrically induced osteogenesis. II. Experimental studies].

The paper presents the possibilities to induce osteogenesis using different types of electrical current. The direct current may be used with invasive or semi-invasive methods. Electrodes are placed internally, near the bone. Experiments showed that the optimum stimulation is achieved with current between 5 and 20 microamperes. The capacitive current is able to induce osteogenesis. The electrodes are placed externally; between the electrodes there is an electric field with the value ranged 1-10 millivolts/cm. The method of pulsed electromagnetic fields is based on the field produced by a coil placed externally. The magnetic field range between 0, 1 and 20 gauss. This is the most appreciate method because is noninvasive and offered the best experimental results.
