Existing research is mostly limited to case-control studies or case series, with no statistical assessment of treatment outcomes. The absence of a standardized surgical approach and the scarcity of statistically significant outcome data highlight the relevance of further research into this topic.</p> <p><bold>AIM:</bold><italic> </italic>The work aimed to assess treatment efficacy in patients with spinal deformities associated with neurological deficit.</p> <p><bold>METHODS:</bold> A retrospective analysis of surgical treatment outcomes was conducted in 51 patients with spinal deformities associated with neurological deficit. Patients were divided into three groups based on the surgical technique used. All patients underwent standard diagnostic examinations. Based on CT myelography findings, individualized 3D models of the spine and spinal cord were created (<italic>n</italic> = 23), and customized implants were manufactured (<italic>n</italic> = 8). Patient questionnaires were used, and neurological status was assessed using the Frankel, ASIA, and FIM scales.</p> <p><bold>RESULTS:</bold><italic> </italic>A significant regression of neurological deficit was observed in patients classified as Frankel B, C, or D. Motor function improved within days after surgery, whereas sensory function improved on average within six months. Spinal cord decompression at the site of maximal stenosis was found to be a key factor influencing neurological deficit regression.</p> <p><bold>CONCLUSION:</bold> Postoperative neurological deficit regression is determined by its severity and duration prior to surgery, as well as adequate spinal cord decompression at the site of maximal spinal stenosis. Patient-specific 3D models of the spine and spinal cord are a valuable tool for assessing local spinal cord compression.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Хирургическое лечение пациентов с деформациями позвоночника, сопровождающимися неврологическим дефицитом, является дискутабельным. Имеющиеся исследования, как правило, представлены форматом «случай — контроль» или серией клинических случаев и не содержат статистической оценки результатов лечения. Отсутствие систематизированного подхода к хирургическому вмешательству и недостаток статистически значимых данных о результатах лечения подчёркивают высокую актуальность изучения данной темы.</p> <p><bold>Цель.</bold> Оценить эффективность лечения пациентов с деформацией позвоночника, ассоциированной с неврологическим дефицитом.</p> <p><bold>Материалы</bold><bold> </bold><bold>и</bold><bold> </bold><bold>методы.</bold> Проведён ретроспективный анализ результатов хирургического лечения 51 пациента с деформацией позвоночника, ассоциированной с неврологическим дефицитом. Пациенты были разделены на три группы в зависимости от метода хирургического лечения. Всем пациентам проведены стандартные методы обследования. На основе данных КТ-миелографии изготовлены индивидуальные 3D-модели (<italic>n</italic>=23) позвоночника и спинного мозга и индивидуальные металлоконструкции (<italic>n</italic>=8). Проведены анкетирование пациентов и оценка неврологического статуса с использованием шкал Frankel, ASIA, FIM.</p> <p><bold>Результаты.</bold> У всех пациентов из групп B, C и D по Frankel выявлен статистически значимый регресс неврологического дефицита. Улучшение моторной функции отмечалось в первые дни после операции, а чувствительность улучшалась в среднем через 6 мес. Было установлено, что на регресс неврологического дефицита влияет декомпрессия спинного мозга в зоне максимального стеноза.</p> <p><bold>Заключение.</bold> Регресс неврологического дефицита в послеоперационном периоде зависит от степени выраженности, продолжительности неврологического дефицита до операции и адекватной декомпрессии спинного мозга в зоне максимального стеноза позвоночного канала. 3D-модели позвоночника и спинного мозга являются важным инструментом для визуализации локальной компрессии спинного мозга.</p></trans-abstract><kwd-group xml:lang="en"><kwd>kyphosis</kwd><kwd>scoliosis</kwd><kwd>kyphoscoliosis</kwd><kwd>neurological deficit</kwd><kwd>decompression</kwd><kwd>additive technologies</kwd><kwd>3D spine model</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>кифоз</kwd><kwd>сколиоз</kwd><kwd>кифосколиоз</kwd><kwd>неврологический дефицит</kwd><kwd>декомпрессия</kwd><kwd>аддитивные технологии</kwd><kwd>3D-модель позвоночника</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Goel SA, Neshar AM, Chhabra HS.
