Однако в ряде случаев после изолированных декомпрессивных вмешательств хирурги также отмечают улучшение регионарного и глобального баланса. Остается вопрос – каковы механизмы и предикторы спонтанной коррекции сагиттального баланса после декомпрессивного вмешательства на поясничном отеле позвоночника.</p></sec><sec><title>Цель исследования</title><p>Цель исследования: определить изменения сагиттального профиля позвоночника после проведения декомпрессивного вмешательства у пациентов с дегенеративным поясничным стенозом</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: Дизайн – проспективное наблюдательное исследование. 96 пациентам выполнена микрохирургическая декомпрессия по поводу дегенеративного поясничного стеноза на всех клинически значимых уровнях. Изучены клинико-рентгенологические результаты лечения с оценкой параметров сагиттального профиля (Pi, Pt, SS, LowLL, LL, SVA, Index Barrey и др.) до и через 6 месяцев после операции.</p></sec><sec><title>Результаты</title><p>Результаты: В послеоперационном периоде зарегистрировано значимое увеличение нижнепоясничного лордоза LowLL (L4-S1) (p=0.03), увеличение сегментарных углов L2-L3, L3-L4, L4-L5, L5-S1 (p&lt;0.05), снижение индекса Barrey (p=0.048), что свидетельствует о спонтанной коррекции регионарного и глобального баланса позвоночника без хирургической коррекции позвоночно-тазовых параметров. Значимыми предикторами такой коррекции после проведения изолированной декомпрессии на поясничном отделе позвоночника являются значение Pelvic Incidence до операции (p=0.07), возраст пациента (p &lt;0.001), значение SVA до операции (p=0.002).</p></sec><sec><title>Заключение</title><p>Заключение: При изолированных декомпрессивных вмешательствах, выполненных у пациентов с дегенеративным стенозом позвоночного канала, отмечается улучшение регионарных и глобальных угловых параметров сагиттального баланса, то есть спонтанная коррекция баланса без применения каких-либо корригирующих маневров. Предикторами спонтанной коррекции баланса при выполнении таких вмешательств являются значение PI, возраст пациента, значение SVA перед операцией. Изолированная декомпрессия интраканальных сосудисто-нервных образований на поясничном уровне позволяет в ряде случаев устранить ортопедические проблемы пациента, на которые хирургическое вмешательство не было первоначально направлено.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: Correction of sagittal imbalance in patients with degenerative spine conditions is typically achieved through corrective decompressingstabilizing procedures that restore angular relationships in the spine. In some cases, however, surgeons have observed an improvement in both regional and overall balance after isolated decompressions. The question that remains is what mechanisms and factors contribute to the spontaneous correction of sagittal alignment after lumbar decompression surgery.</p></sec><sec><title>AIMS</title><p>AIMS: to determine changes in the sagittal profile of the spine after decompression surgery in patients who have undergone decompression surgery for degenerative lumbar stenosis.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: prospective observational study of 96 patients who underwent microsurgical decompression for degenerative lumbar stenosis at all clinically significant levels. Clinical and radiological outcomes were assessed by measuring various parameters of the sagittal profile, such as Pi, Pt, SS, low LL, LL, SVA, and Barrey index, both before and 6 months after surgery.</p></sec><sec><title>RESULTS</title><p>RESULTS: In the postoperative period, a significant increase in lower lumbar lordosis LowLL (L4-S1) (p=0.03), an increase in segmental angles L2-L3, L3-L4, L4-L5, L5-S1 (p&lt;0.05), a decrease in the Barrey index (p=0.048), indicating a spontaneous correction of regional and global balance of the spine without surgical correction of vertebral-pelvic parameters. Significant predictors of this correction after isolated lumbar decompression were the Pelvic Incidence value before surgery (p=0.07), the patient's age (p&lt;0.001), and the SVA value before surgery (p=0.002).</p></sec><sec><title>CONCLUSIONS</title><p>CONCLUSIONS: In isolated decompressive surgeries performed on patients with degenerative spinal stenosis, there has been an improvement in both regional and global sagittal alignment parameters. This means that there has been a spontaneous correction of the balance without the need for any corrective measures. Predictors for this spontaneous balance correction include a Pi value, a patient age, and a preoperative SVA value. Isolated decompression of the intracranial neurovascular structures at the lumbar level can sometimes eliminate orthopedic issues that were not initially targeted by surgery.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Сагиттальный баланс</kwd><kwd>коррекция угловых взаимоотношений</kwd><kwd>поясничный стеноз</kwd><kwd>декомпрессия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Sagittal balance</kwd><kwd>correction of angular relationships</kwd><kwd>lumbar stenosis</kwd><kwd>decompression</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование не имело спонсорской поддержки</funding-statement><funding-statement xml:lang="en">the study had no sponsorship</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Deer T, Sayed D, Michels J, Josephson Y, Li S, Calodney AK.
