Based on the identified predictors and their threshold values, a set of essential preoperative examinations for decompression and stabilization surgery planning was developed. The effectiveness of the predictive model and the feasibility of the proposed set of preoperative examinations were assessed in a prospective patient cohort.</p> <p><bold>RESULTS:</bold><italic> </italic>Multivariate analysis identified the following as significant predictors of treatment success: preoperative ODI score, preoperative HADS score, DN4 score, presence of interbody fusion, postoperative lower lumbar lordosis angle, bone mineral density in HU, and postoperative segmental angle. The threshold value for lower lumbar lordosis (Low LL, L4–S1) was 26° (sensitivity, 71.7%; specificity, 91.3%); the segmental angle (SL) threshold was 7° (sensitivity, 87.9%; specificity, 70.6%). The proposed set of essential preoperative examinations for single-level decompression and stabilization surgery planning includes clinical scales (ODI, HADS, DN4), standing spinal radiographs, and lumbar CT and MRI. This set of essential preoperative examinations resulted in a 9.3% increase in clinical success rate (from 74.8% to 84.1%).</p> <p><bold>CONCLUSION:</bold><italic> </italic>The set of essential preoperative examinations includes three questionnaires (ODI, HADS, and DN4) and three imaging modalities (standing radiographs, lumbar CT, and lumbar MRI), all of which are typically available at specialized spinal surgery centers. This set is recommended for routine use by spine surgeons, given its role in achieving predictable success following single-level decompression and stabilization surgery of the lumbar spine.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Отсутствие обязательного комплекса предоперационного обследования для пациентов с планируемым хирургическим вмешательством при дегенеративных патологиях позвоночника приводит к недоучёту наиболее значимых предикторов и не позволяет получить прогнозируемый клинико-рентгенологический результат.</p> <p><bold>Цель.</bold> Уточнение объёма предоперационного обследования пациентов с запланированным декомпрессивно-стабилизирующим вмешательством по поводу дегенеративного заболевания поясничного отдела позвоночника.</p> <p><bold>Материалы</bold><bold> </bold><bold>и</bold><bold> </bold><bold>методы.</bold> В ходе анализа ретроспективной когорты были выявлены предикторы успешности лечения после проведённого моносегментарного декомпрессивно-стабилизирующего вмешательства. С учётом выявленных предикторов и их пороговых значений был сформирован минимальный комплекс обязательного предоперационного обследования, необходимый для выполнения при планировании данного вида вмешательства. Оценка эффективности прогностической модели и целесообразности применения комплекса предоперационного обследования проводилась на проспективной когорте пациентов.</p> <p><bold>Результаты.</bold> При многомерном анализе значимыми предикторами комплексного успеха определены значения опросника ODI до операции, опросника HADS до операции, опросника DN4, наличие сформированного межтелового блока, значения нижнепоясничного лордоза после операции, минеральной плотности костной ткани в HU, сегментарного угла после операции. Пороговое значение для нижнепоясничного лордоза Low LL (L4-S1) составило 26° (чувствительность — 71,7%, специфичность — 91,3%), для сегментарного угла SL — 7° (чувствительность — 87,9%, специфичность — 70,6%). Предлагаемый минимальный обязательный комплекс предоперационного обследования при планировании моносегментарного декомпрессивно-стабилизирующего вмешательства включает клинические шкалы (ODI, HADS тревога, DN4), постуральную рентгенографию позвоночника, КТ и МРТ поясничного отдела позвоночника. В результате применения комплекса обязательного предоперационного обследования частота достижения клинического успеха пациентами увеличилась на 9,3% (с 74,8 до 84,1%).</p> <p><bold>Заключение.</bold> Минимальный обязательный комплекс предоперационного обследования содержит три опросника (ODI, HADS тревога, DN4) и три вида лучевых методов обследования (постуральная рентгенография, КТ и МРТ поясничного отдела позвоночника), которые доступны в большинстве специализированных клиник хирургии позвоночника. Использование данного комплекса целесообразно для применения в рутинной практике вертебролога ввиду достижения прогнозируемого успеха после проведённого моносегментарного декомпрессивно-стабилизирующего вмешательства на поясничном уровне.</p></trans-abstract><kwd-group xml:lang="en"><kwd>preoperative examination</kwd><kwd>decompression and stabilization surgery</kwd><kwd>degenerative spine disease</kwd><kwd>lumbar spine</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>предоперационное обследование</kwd><kwd>декомпрессивно-стабилизирующие вмешательства</kwd><kwd>дегенеративные заболевания позвоночника</kwd><kwd>поясничный отдел позвоночника</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Lafian AM, Torralba KD.
