The Effectiveness of Laser Vaporization in the Treatment of Intervertebral Hernias of the Lumbar Spine
Abstract
The purpose of the study: assessment of the use of laser vaporization of the disc with hernial protrusion on the lumbar spine and its effectiveness in the treatment of pain.Material and methods. We analyzed the effectiveness laser vaporization in 230 patients with degenerative-dystrophic diseases of the lumbar spine (protrusions and hernias of the intervertebral discs) treated in the neurosurgical department of the Irkutsk Scientific Centre of Surgery and Traumatology for the period from 2011 to 2018. There were 122 men and 108 women. The average age of the patients was 41 years. The duration of the disease before surgical treatment is 11 ± 3 weeks. Clinical and neurological examination revealed lumbalgia in 102 patients (44.3 %), lumbar ischalgia in 98 (42.6 %) and radiculopathy in 30 patients (13.1 %). Median hernias of the intervertebral discs were revealed in 130 patients (56.4 %), lateral hernias - in 41 (17.8 %) and protrusions - 59 (23.8 %). The leading localization of the pathological process was the LIV-LV segment (138 patients, 60 %). Assessment of the effectiveness of surgical treatment was carried out using VAS and Macnab scales.Results. In 100 % of cases were laser vaporization was applied a decrease in the intensity of the pain syndrome was achieved in terms of up to 3 months. The analysis of the long-term results of this treatment in 124 patients from 3 months to 3 years by Macnab scale revealed excellent results in 25 (20.1 %) patients, good results - in 50 (40.3 %), satisfactory - in 42 (33.8 %), and unsatisfactory results - in 7 (5.6 %) cases.Conclusion. Thus, laser vaporization of hernias of the intervertebral disc is effective in the treatment of pain, which does not stop with conservative treatment for 4-6 weeks; with a hernia of up to 6 mm; with a median localization and with no signs of sequestration.
