The data of 42 patients were analyzed. PSO (group I) was performed in 12 patients; 30 patients had a combination of surgical methods (group II) with mandatory ventral corrective spinal fusion at levels L4-L5, L5-S1. Clinical and radiological parameters were evaluated during hospitalization and at least 1 year later.</p> <p><bold>Results.</bold> Postoperative hospitalization in group I — 32.5 ± 7.4 days, 27.1 ± 7.4 in group II (p = 0.558758). The duration of the operation in group I was 402.5 ± 55.6 minutes, in group II 526.0 ± 116.2 minutes (p = 0.001124); blood loss 1862.5 ± 454.3 ml versus 1096.0 ± 543.3 ml (p = 0.000171). In both groups, significantly improved clinical and radiological parameters after surgery and after 1 year (p &lt; 0.05). In group II, as compared with group I after surgery and more than 1 year: lower back pain according to VAS (p = 0.015424 and p = 0.015424); below ODI after 1 year was (p = 0.000001). In group I, compared with group II after surgery and after 1 year, SVA is less (p = 0.029879 and p = 0.000014), lumbar lordosis is higher (p = 0.045002 and p = 0.024120), LDI is restored more optimally (p = 0.000001 and p = 0.000002), the GAP is lower (p = 0.005845 and p = 0.002639). The ideal Russoly type is restored more often in patients of group II (p = 0,00032). Complications in group I were noted in 12 (100%) patients, in group II — in 13 (43.3%) patients (p = 0.001).</p> <p><bold>Conclusions. </bold>In multistep surgical treatment compared with PSO, the anterior corrective interbody fusion L4-L5, L5-S1 reliably better and more harmoniously restores the sagittal balance parameters, has significantly lower volume of intraoperative blood loss, fewer perioperative complications and significantly improves the quality of life of patients.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Сравнить клинико-рентгенологические результаты лечения пациентов с деформациями позвоночника, оперированных методом педикулярной субтракционной остеотомии (Pedicle Subtraction Osteotomy – PSO) и корригирующим спондилодезом на поясничном отделе позвоночника.</p> <p><bold>Материалы и методы.</bold> Проведено ретроспективное моноцентровое когортное исследование. Проанализированы данные 42 пациентов. PSO (I группа) выполнена 12 пациентам; 30 пациентам — комбинация хирургических методов (II группа) с обязательным вентральным корригирующим спондилодезом на уровнях L4-L5, L5-S1. Клинико-рентгенологические параметры оценены в период госпитализации и минимум через 1 год.</p> <p><bold>Результаты.</bold> Послеоперационная госпитализация в I группе 32,5 ± 7,4 дня, 27,1 ± 7,4 дня — во II группе (p = 0,558758). Продолжительность операции в I группе 402,5 ± 55,6 мин, во II группе — 526,0 ± 116,2 мин (p = 0,001124); кровопотеря 1862,5 ± 454,3 мл против 1096,0 ± 543,3 мл (p = 0,000171). В обеих группах значимо улучшены клиническо-рентгенологические параметры после операции и через 1 год (p &lt; 0,05). Во II группе в сравнении с I после операции и через 1 год: ниже боль в спине по визуально-аналоговой шкале боли (Visual Analog scale — VAS) (p = 0,015424 и p = 0,015424); ниже ODI (Osvestry Disability Index) через 1 год (p = 0,000001). В I группе в сравнении со II группой после операции и через 1 год SVA меньше (p = 0,029879 и p = 0,000014 соответственно), поясничный лордоз выше (p = 0,045002 и p = 0,024120), LDI (Lordosis Distribution Index) восстановлен оптимальнее (p = 0,000001 и p = 0,000002), GAP (Global Alignment and Proportion) ниже (p = 0,005845 и p = 0,002639). Идеальный тип Russoly восстановлен чаще у пациентов II группы (p = 0,00032). Осложнения в I группе отмечены у 12 (100 %), во II группе — у 13 (43,3 %) пациентов (p = 0,001).</p> <p><bold>Выводы.</bold> Передний корригирующий межтеловой спондилодез L4-L5, L5-S1 в многоэтапном хирургическом лечении в сравнении с PSO достоверно лучше и гармоничнее восстанавливает параметры сагиттального баланса, имеет значительно ниже объем интраоперационной кровопотери, меньше периоперационных осложнений и значительно улучшает качество жизни пациентов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>spinal deformity in adults</kwd><kwd>degenerative scoliosis</kwd><kwd>sagittal imbalance</kwd><kwd>PSO</kwd><kwd>vertebrotomy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>деформация позвоночника у взрослых</kwd><kwd>дегенеративный сколиоз</kwd><kwd>сагиттальный дисбаланс</kwd><kwd>PSO</kwd><kwd>вертебротомия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Schwab F, Patel A, Ungar B, et al.
