Abstract
Objective. Comparative analysis of surgical results in patients with thoracolumbar and lumbar idiopathic scoliosis treated by laminar and transpedicular fixation. Material and Methods. Two groups of patients with lumbar and thoracolumbar idiopathic scoliosis were operated on. Patients from Group 1 underwent skeletal traction applied to calvarial bones and supramalleolar area, and correction of spinal deformity with third-generation segmental instrumentation using laminar fixation. Patients from Group 2 underwent skeletal traction applied to calvarial bones and supramalleolar area, and correction of spinal deformity with third-generation hybrid segmental instrumentation using laminar fixation in the thoracic spine and transpedicular fixation in the lumbar or thoracolumbar spine. Results. In Group 1 the scoliotic deformity was reduced from an average of 63.8° ± 21.1° to 24.7° ± 13.7°; postoperative progression was 6.8° ± 1.1° (18.6 ± 2.5 %); and tilt angle of the lower instrumented vertebra before surgery, after surgery, and at follow-up was 9.5° ± 8.4°, 8.2° ± 5.4°, and 10.0° ± 5.9°, respectively. In Group 2 the deformity was reduced from an average of 55.9° ± 16.6° to 13.4° ± 11.2°; postoperative progression was 2.4° ± 0.7° (5.8 ± 1.8 %); and tilt angle of the lower instrumented vertebra before surgery, after surgery, and at follow- up - 17.6° ± 7.6°, 5.2° ± 4.3°, and 5.6° ± 4.5°, respectively. Conclusion. Transpedicular fixation is more effective technique of surgical treatment for lumbar and thoracolumbar scoliosis than laminar fixation.

Summary
Сравнительный анализ результатов хирургического лечения пациентов с идиопатическим сколиозом поясничной и грудопоясничной локализации с применением ламинарной и транспедикулярной фиксации. Прооперировано две группы пациентов с идиопатическим сколиозом поясничной и грудопоясничной локализации. В I группе применяли скелетное вытяжение за кости свода черепа и надлодыжечные области и коррекцию деформации позвоночника сегментарным инструментарием III поколения с ламинарной фиксацией; во II– скелетное вытяжение за кости свода черепа и надлодыжечные области и коррекцию деформации позвоночника гибридным сегментарным инструментарием III поколения с ламинарной фиксацией грудного отдела позвоночника и транспедикулярной фиксацией поясничного или грудопоясничного отдела позвоночника. Транспедикулярная фиксация является более эффективным методом хирургического лечения поясничных и грудопоясничных сколиозов, чем ламинарная фиксация. Ключевые слова: идиопатические поясничные и грудопоясничные сколиозы, хирургическая коррекция, транспедикулярная фиксация.
