On the treatment of vertebrogenic pain using laser-induced lesion of the spinal ganglia.

Recently, there has been an increase in the use of spinal-ganglia lesions as a means of surgical treatment of postdiscotomic algic syndromes. After relapses following thermocoagulation, the authors began to use lesions caused by a laser beam of an output of 30 W and temperature of 2,000 degrees C. As the resulting changes are irreversible, lasting effects of the procedure can be expected.
