Performing preoperative diagnostic aspiration in patients with the installed hip spacer is a controversial issue.</p> <p><bold>Aims of the study: </bold>1) to compare the diagnostic accuracy, specificity and sensitivity of the used infection markers as a part of preoperative diagnostic protocols in order to exclude reinfection in patients with installed hip spacer before the second stage of RHA; 2) to analyze and compare the microbiological spectrum obtained at the stages of RHA.</p> <p><bold>Methods. </bold>Diagnostic accuracy parameters of the used infection markers were assessed in order to exclude reinfection/recurrence in 107 patients with installed hip spacer. All patients were divided into two groups. In Group 1 (prospective), blood tests as well as diagnostic aspiration of synovial fluid were performed within the extended diagnostic protocol. In Group 2 (retrospective), the examination was performed according to the screening preoperative diagnostic protocol including blood tests. The used reference range of inflammatory biomarkers was based on the “small criteria” of ICM 2018. According to the results of the intraoperative microbiological examination of peri-implant tissue samples at the first and second stages of RHA, the analysis of detected microflora was conducted in order to assess probable reinfection/recurrence.</p> <p><bold>Results. </bold>According to the results of the intraoperative microbiologic examination during the second stage of RHA, reinfection was detected in 40% of cases: in Group 1 — 9 cases, in Group 2 — 31 case. Synovial fluid was obtained from 85% of cases when preoperative diagnostic aspiration was performed. Synovial fluid could not be obtained in 15% cases (dry joint).</p> <p><bold>Conclusion. </bold>Performing preoperative diagnostic aspiration before the second stage of RHA in patients with the installed spacer allowed choosing correct treatment tactics in 9% of cases. The parameters of diagnostic accuracy accounted for 82,6%. In the structure of detected pathogens in case of recurrence and reinfection, the representatives of Gram-positive coagulase-negative flora were the most frequent.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность. </bold>Показатели реинфекции или рецидива перипротезной инфекции при выполнении второго этапа ревизионного эндопротезирования тазобедренного сустава (РЭТС) остаются достаточно высокими. Выполнение предоперационной диагностической аспирации у пациентов с установленным спейсером тазобедренного сустава является дискутабельным вопросом.</p> <p><bold>Цели исследования: </bold>1)<bold> </bold>сравнить диагностическую точность, специфичность и чувствительность используемых маркеров инфекции в рамках предоперационных диагностических протоколов для исключения реинфекции у пациентов с установленным спейсером тазобедренного сустава перед вторым этапом ревизионного эндопротезирования тазобедренного сустава; 2) проанализировать и сравнить микробиологический пейзаж, полученный на этапах ревизионного эндопротезирования тазобедренного сустава.</p> <p><bold>Материал и методы. </bold>Проведена оценка показателей диагностической точности используемых маркеров инфекции с целью исключения реинфекции/рецидива у 107 пациентов с установленным спейсером тазобедренного сустава. Пациенты были разделены на две группы: 1-я группа — проспективная, в которой использовался расширенный диагностический протокол с выполнением диагностической аспирации синовиальной жидкости и анализов крови; 2-я группа — ретроспективная, в которой использовался скрининговый диагностический протокол<bold> </bold>с выполнением анализов крови. Используемые референсные значения биомаркеров реинфекции основывались на «малых критериях» протокола ICM (2018). По результатам интраоперационного микробиологического исследования образцов периимплантных тканей на первом и втором этапах РЭТС был проведен анализ полученной микрофлоры с целью оценки вероятного рецидива/реинфицирования.</p> <p><bold>Результаты. </bold>Реинфекция в обеих группах по результатам интраоперационного микробиологического исследования при выполнении второго этапа РЭТС диагностирована в 40% случаев: в 1-й группе пациентов — 9 случаев, во 2-й группе — 31 случай. Синовиальная жидкость при выполнении предоперационной аспирации была получена в 85% случаев, «сухой сустав» — в 15%.</p> <p><bold>Заключение. </bold>Выполнение предоперационной диагностической аспирации перед вторым этапом РЭТС у пациентов с установленным спейсером позволило в 9% случаев выбрать правильную тактику лечения, продемонстрировав показатель диагностической точности в 82,6%. Преобладающая микрофлора в структуре реинфекции тазобедренного сустава при выполнении второго этапа РЭТС представлена грамположительными коагулазонегативными микроорганизмами.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>diagnostics of hip periprosthetic infection</kwd><kwd>recurrence of infection</kwd><kwd>synovial fluid aspiration</kwd><kwd>hip spacer</kwd><kwd>revision hip arthroplasty</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>диагностика периимплантной инфекции тазобедренного сустава</kwd><kwd>рецидив инфекции</kwd><kwd>аспирация синовиальной жидкости</kwd><kwd>лабораторная диагностика периимплантной инфекции тазобедренного сустава</kwd><kwd>спейсер тазобедренного сустава</kwd><kwd>ревизионное эндопротезирование тазобедренного сустава</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Департамент здравоохранения г.
