A total of 34 patients underwent empirical antibiotic therapy followed by open debridement, whereas 29 patients received early minimally invasive debridement with percutaneous drainage of the destroyed disc and psoas abscess followed by targeted antibiotic therapy. Vertebral involvement was assessed according to the Pola classification. Neurological status, laboratory parameters including bacteriological tests, duration of hospital stay, and findings of magnetic resonance imaging and computed tomography were evaluated. Functional status was assessed using the Visual Analog Scale for pain, the Rivermead Mobility Index, and the Oswestry Disability Index at baseline and at the end of treatment. Follow-up lasted at least 6 months after discharge.</p> <p><bold>RESULTS: </bold>In acute nonspecific vertebral osteomyelitis, early (within the first 24 hours of admission) percutaneous biopsy of the lesion with closed drainage, compared with empirical antibiotic therapy with subsequent surgery in cases of failure, increased pathogen verification from 41.1% to 89.7% (<italic>p</italic> &lt; 0.01), reduced overall treatment duration from 71.1 ± 16.6 to 46.3 ± 18.3 days (<italic>p</italic> &lt; 0.01), and decreased the risk of delayed segmental instability from 41.0% to 20.6% (<italic>p</italic> &lt; 0.01), with comparable mortality, hospital stay duration, and patients’ functional status at treatment completion. The use of minimally invasive methods with targeted antibiotic therapy did not require any open procedures throughout the treatment period, whereas in the empirical therapy group, subsequent open drainage of abscesses and destruction sites was performed in 76.4% of cases.</p> <p><bold>CONCLUSION: </bold>Minimally invasive diagnostics and drainage of pathological foci are effective in treating nonspecific lumbar spondylodiscitis without neurological complications, including cases complicated by sepsis.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Эффективность малоинвазивного пункционного дренирования зоны деструкции и паравертебральных абсцессов при неспецифическом гнойном спондилодисците недостаточно изучена.</p> <p><bold>Цель.</bold> Оценить эффективность лечения острого неспецифического спондилодисцита поясничного отдела позвоночника путём чрескожного дренирования очага воспаления с таргетной антибактериальной терапией в сравнении с традиционной эмпирической антибактериальной терапией с последующим хирургическим лечением.</p> <p><bold>Материалы и методы. </bold>В контролируемом пилотном одноцентровом экспериментальном ретроспективном когортном исследовании изучены качественные данные 63 пациентов (33 женщины и 30 мужчин, средний возраст 56,79 года) с первичным неспецифическим моносегментарным (39 пациентов) и полисегментарным (24 пациента) спондилодисцитом поясничных позвонков. 34 пациентам проведено лечение с использованием эмпирической антибактериальной терапии с последующей открытой санацией, 29 — ранняя малоинвазивная санация с чрескожным дренированием разрушенного диска и псоас-абсцесса с последующей таргетной антибактериальной терапией. Поражения позвонков оценены в соответствии с классификацией E. Pola. Изучены неврологический статус пациентов, лабораторные показатели, в том числе бактериологические, длительность стационарного лечения, данные магнитно-резонансной и компьютерной томографии. Функциональный статус оценивали с помощью визуально-аналоговой шкалы боли, индекса Ривермид и опросника Освестри в начале и по завершении лечения. Катамнез прослежен в сроки не менее 6 месяцев после выписки из стационара.</p> <p><bold>Результаты. </bold>При остром неспецифическом остеомиелите позвонков ранняя (в первые сутки после поступления) чрескожная биопсия очага поражения с его закрытым дренированием в сравнении с эмпирической антибактериальной терапией с применением хирургического лечения в случае её неэффективности обеспечивает повышение уровня верификации возбудителя с 41,1 до 89,7% (<italic>р</italic> &lt; 0,01), снижение общей длительности лечения с 71,1 ± 16,6 до 46,3 ± 18,3 сут. (<italic>р</italic> &lt; 0,01) и риска отсроченной сегментарной нестабильности с 41,0 до 20,6% (<italic>р</italic> &lt; 0,01) при сопоставимом уровне летальности, длительности стационарного лечения и функциональном статусе пациентов к моменту завершения лечения. Применение малоинвазивных методов с таргетной антибактериальной терапией не потребовало на протяжении всего периода лечения выполнения открытых вмешательств, в то время как при эмпирической антибактериальной терапии последующие открытые дренирования абсцессов и очагов деструкции выполнены в 76,4% случаев.</p> <p><bold>Заключение.</bold> Малоинвазивная диагностика и дренирование патологических очагов эффективны при лечении не осложнённого неврологическими нарушениями неспецифического спондилодисцита поясничного отдела позвоночника, в том числе осложнённого сепсисом.</p></trans-abstract><kwd-group xml:lang="en"><kwd>spinal osteomyelitis</kwd><kwd>spondylitis</kwd><kwd>spondylodiscitis</kwd><kwd>minimally invasive drainage</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>остеомиелит позвоночника</kwd><kwd>спондилит</kwd><kwd>спондилодисцит</kwd><kwd>малоинвазивное дренирование</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kehrer M, Pedersen C, Jensen TG, Lassen AT.
