The information was collected by studying archived medical records and a medical information system, by examining patients in the outpatient clinic, and by interviewing patients via mobile phone and e-mail. During the period, we treated 449 patients with hip periprosthetic infection. The mean patients’ age was 55.6±12.6 years (Ме — 57; 95% CI: 54.4-56.8). Male patients accounted for 61.6% (n = 277).</p> <p><bold>Results. </bold>We were able to evaluate the treatment results in 84% (n = 377) of patients. The mean follow-up period was 5.92±2.55 years (Me — 6; 95% CI: 2.39-2.73). In more than 90% (n = 407) of cases, the infection was classified as chronic (more than 3 weeks of manifestation). At the admission 76,8% (n = 345) of patients had a fistula communicating with the joint cavity. The percentage of lethal outcomes due to sepsis was 1,7% (8/449); recurrences of hip PJI was observed in 6.2% (28/ 449) of cases. Resolution of infection has been achieved in 67% (300/449) of cases.</p> <p><bold>Conclusions. </bold>The primary analysis of the data from the local registry of hip periprosthetic infection of the national Ilizarov Center of Traumatology and Orthopedics showed that the average age of patients with hip PJI in our country is significantly lower than in the known national registries. At the same time, the infectious agents were similar: Gram-positive microorganisms accounted for more than 55%. The analysis of the registry data shows a significant decrease in the PJI recurrence rate over the last 5 years.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность. </bold>Точные данные об эпидемиологии перипротезной инфекции (ППИ) тазобедренного сустава в Российской Федерации получить сложно, что связано с особенностями статистической регистрации осложнений и отсутствием утвержденных схем маршрутизации пациентов.</p> <p><bold>Цель работы</bold> — представить результаты первичного анализа данных локального регистра ППИ тазобедренного сустава, в котором отражены все случаи лечения этой патологии с 01.01.2010 по 31.12.2020.</p> <p><bold>Материал и методы.</bold> С 2021 г. проводилась ретроспективная работа по внесению в электронную версию регистра данных о пациентах с ППИ тазобедренного сустава, получавших лечение в клинике Центра. Сбор информации осуществлялся посредством работы с архивными историями болезни и медицинской информационной системой, осмотра пациентов в поликлинике, опроса больных по мобильной связи и электронной почте. За указанный период были пролечены 449 пациентов с ППИ. Средний возраст пациентов составил 55,6±12,6 лет (Ме — 57; 95% ДИ: 54,4–56,8). Пациенты мужского пола составляли 61,6% (<italic>n</italic> = 277).</p> <p><bold>Результаты.</bold> Нам удалось оценить результаты лечения у 84% (<italic>n </italic>= 377) больных. Средний срок наблюдения за пациентами составил 5,92±2,55 года (Me — 6; 95% ДИ: 2,39–2,73). В более чем 90% (<italic>n </italic>= 407) случаев инфекция была классифицирована как хроническая (более 3 нед. манифестации), 76,8% пациентов (<italic>n </italic>= 345) при поступлении имели свищевой ход, сообщающийся с полостью сустава. Летальный исход на фоне септического состояния зарегистрирован у 1,7% (8 из 449) больных, рецидив ППИ — в 6,2% (28 из 449) случаев, купирование инфекции — в 67% (300 из 449).</p> <p><bold>Заключение. </bold>Первичный анализ данных локального регистра ППИ тазобедренного сустава в центре Илизарова показал, что средний возраст пациентов с ППИ в нашей стране значительно ниже, чем в известных национальных регистрах. В то же время структура возбудителей инфекции была схожа: грамположительные микроорганизмы составляли более 55%. Анализ данных регистра демонстрирует значительное снижение частоты рецидивов ППИ за последние 5 лет.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>periprosthetic infection</kwd><kwd>local registry</kwd><kwd>revision hip arthroplasty</kwd><kwd>fistula</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>перипротезная инфекция</kwd><kwd>локальный регистр</kwd><kwd>ревизионное эндопротезирование тазобедренного сустава</kwd><kwd>свищевой ход</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kini S.G., Gabr A., Das R., Sukeik M., Haddad F.S.
