Purpose: a comparative analysis of long-term clinical and radiological outcomes of bilateral microsurgical decompression from unilateral approach and open fusion surgery in the treatment of patients with stable stage I lumbar degenerative spondylolisthesis complicated by spinal stenosis. Materials and methods: this study included 83 patients with degenerative stage I lumbar spondylolisthesis, combined with spinal stenosis at one/several levels. Bilateral microsurgical decompression from unilateral approach was performed in group A (n = 41), in group B (n = 42) we used transforaminal lumbar interbody fusion. Results: intraoperative blood loss and operation time significantly prevailed in group B (P < 0,05). Pain in the legs (VAS), Oswestry disability index significantly decreased in both groups in the long-term postoperative period. No statistical difference in these was found in groups A and B (P = 0,59; P = 0,10). Lower back pain in both groups at the follow-up period had a significant difference: in fusion group there was a significantly higher intensity, than in group А (P < 0,001). Assessment of radiological outcomes in group A at the level of spondylolisthesis showed a slight decrease in segment stability: an increase in anteroposterior displacement of the vertebrae by an average of 0,44 mm, the angular difference by 0,77°, an increase in displacement of the vertebral body by 1,30 % (P < 0,05). Conclusion: minimally bilateral microsurgical decompression from unilateral approach is an effective method for treatment of stable stage I degenerative lumbar spondylolisthesis, combined with spinal stenosis, allowing to achieve significant regression of leg pain and disability in the long-term postoperative period. And this method admits to significantly decrease of low back pain, then in fusion surgery, as well as a low risk of postoperative instability and reoperation with instrumentation.
Objective.To analyze clinical and radiological outcomes of minimally invasive bilateral decompression through a unilateral approach in the treatment of patients with degenerative grade I spondylolisthesis combined with lumbar spinal stenosis. Material and Methods.A total of 28 patients with degenerative grade I lumbar spondylolisthesis combined with spinal stenosis at one or several levels with clinical manifestations of neurogenic intermittent claudication and low back pain were operated on using the method of bilateral microsurgical decompression through a unilateral approach. The minimum follow-up period was 1 year. Clinical outcomes was assessed using VAS, Oswestry and MacNab questionnaires. Central stenosis of the spinal canal was graded according to Shizas classifi-Цель исследования. Анализ клинических и рентгенологических исходов минимально-инвазивной двусторонней изолированной декомпрессии из одностороннего доступа в лечении пациентов с дегенеративным спондилолистезом I степени, сочетающимся с поясничным спинальным стенозом. Материал и методы. Прооперированы 28 пациентов с дегенеративным поясничным спондилолистезом I степени, сочетающимся со спинальным стенозом на одном или нескольких уровнях, клиникой нейрогенной перемежающейся хромоты и болью в пояснице методом двусторонней микрохирургической декомпрессии из одностороннего доступа. Минимальный срок наблюдения -1 год. Оценивали клиническихие исходы и неврологический статус по ВАШ, Освестри и MacNab. По данным МРТ оценивали степень центрального стеноза позвоночного канала (по Schizas), по данным функциональных спондилограмм перед операцией и в отдаленном периоде -степень стабильности сегмента (по Hanley), прогрессирование спондилолистеза в нейтральной позиции. Результаты. Средний срок госпитализации -3,07 ± 0,26 сут. Средняя продолжительность операции -145,07 ± 44,67 мин. При оценке боли по ВАШ отмечено значительное снижение медианного значения интенсивности болевого синдрома в ноге -с 7,0 [7,0; 8,0] до 1,0 [1,0; 2,0] балла, в спине -с 5,0 [4,0; 5,0] до 1,0 [1,0; 2,0] балла, снижение медианного показателя нетрудоспособности пациентов по ODI -с 60,0 [56,0; 64,0] до 15,0 [12,0; 19,0]. Оценка рентгенологических исходов показала незначительное увеличение параметров переднезадней трансляции (в среднем +0,42 мм) и сегментарной ротации (в среднем +1,03°) оперированного сегмента при функциональных пробах, незначительное нарастание спондилолистеза (в среднем на 1,42 %), что в целом не повлияло на клинические исходы.Дегенеративные поражения позвоночника Degenerative diseases of the spine Hirurgia Pozvonochnika (spine surgery) 2020;17(4):33-42 ХИРУРГИЯ ПОЗВОНОЧНИКА 2020.
