Percutaneous laser denervation of archoappendicular joints in spinal pain was made in 15 patients from a study group. Percutaneous high-frequency denervation of archoappendicular joints was performed in a control group consisting of 15 patients with facet syndrome. A preoperative protocol for each patient included at least two diagnostic segmental blocks. A surgical intervention was morphologically substantiated during an experiment; the most optimum surgery protocol was chosen. Destruction was performed by 0.97-micron laser radiation for 4-6 sec at 5-10 W. The number of cases of a complete or partial pain regression, the duration of its impact, side effects and complications were determined. Of the 15 patients from the study group, 8 and 6 patients were observed to have a complete and significant pain regression (more than 50% of the baseline). No effect was achieved in one patient. The similar results were obtained in the control group. There were no postoperative infectious complications in the patients of both groups; transient pain dysesthesia was registered in one case. The findings have led to the conclusion that laser denervation of archoappendicular joints is effective in the pain facet syndrome.
