However, the development and refinement of chemotherapy and radiotherapy protocols, along with advances in surgical techniques and implants, have significantly altered the treatment landscape for these patients. Currently, limb-sparing oncologic arthroplasty is the preferred surgical approach for treating limb sarcomas in children.</p> <p><bold>The aim of the systematic review </bold>is to analyse the outcomes of oncologic arthroplasty in children and adolescents.</p> <p><bold>Methods. </bold>A comprehensive literature search was performed in Google Scholar, PubMed, ScienceDirect, and eLIBRARY databases focusing on the keywords “endoprostheses, tumors, children”, from 2000 to 2024. Data collection included patient demographics (number of patients, gender, age), follow-up period, disease diagnosis, tumor location, type of endoprosthesis, complications, functional outcomes based on the Musculoskeletal Tumor Society score (MSTS) in percentage, overall survival rates, and prosthesis survival rates.</p> <p><bold>Results.</bold> The review included the data from 30 articles on a total of 792 patients aged 2 to 18 years, with 422 males and 370 females. The average age was 11.4 years, and the average follow-up period was 6.5 years. Osteosarcoma was the most common diagnosis, accounting for 716 (88.8%) cases, followed by Ewing sarcoma with 67 (8.3%) cases. Distal femoral arthroplasties were performed most frequently (573 cases, 71.1%), followed by proximal tibial arthroplasty (148 cases, 18.3%). The most commonly used type of endoprosthesis was the non-invasively extendable type (540 cases, 67%). A total of 756 complications were recorded, resulting in a complication rate of 96%. The complications were predominantly oncologic (188 cases, 25%) and pediatric orthopedic (166 cases, 22%). The 5-year and 10-year overall survival rates were 81.68% and 77.63%, respectively, with an average prosthesis survival rate of 53.93%.</p> <p><bold>Conclusion. </bold>The data obtained indicate an extremely high frequency of complications during oncologic arthroplasty in children, mainly of an orthopedic profile, which requires analysis and development of measures to prevent them, as well as organizational solutions for the correction of these disorders.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.</bold> При саркомах костей конечностей у детей операцией выбора до 1980-х гг. являлась ампутация. Создание и совершенствование протоколов химиотерапии, лучевой терапии, развитие хирургической техники и имплантатов кардинально изменили возможности и результаты оказания помощи данной группе пациентов. В настоящее время органосохраняющая технология онкологического эндопротезирования является методом выбора в хирургическом лечении детей с саркомами конечностей.</p> <p><bold>Целью систематического обзора </bold>является анализ исходов онкологического эндопротезирования у детей и подростков.</p> <p><bold>Материал и методы. </bold>Поиск источников выполнялся в базах данных Google Scholar, PubMed, ScienceDirect, eLIBRARY по ключевым словам «endoprostheses, tumors, children, эндопротезы, злокачественные опухоли, дети» с глубиной поиска с 2000 по 2024 г. Выполнялся анализ следующих данных: количество пациентов, пол, возраст, период наблюдения, диагноз, локализация опухоли, тип устанавливаемого эндопротеза, наличие осложнений, результаты оценки функции конечности по шкале Musculoskeletal Tumor Society (MSTS) в процентах, общая выживаемость и выживаемость эндопротеза.</p> <p><bold>Результаты. </bold>в<bold> </bold>анализируемый материал вошли данные из 30 статей, включающих всего 792 пациента в возрасте от 2 до 18 лет, из них 422 мальчика и 370 девочек. Средний возраст — 11,4 года, средний период наблюдения — 6,5 лет. На первом месте по встречаемости расположилась остеосаркома — 716 (88,8%) наблюдений, на втором — саркома Юинга — 67 (8,3%). Чаще всего выполнялось эндопротезирование дистального отдела бедренной кости — 573 (71,1%), а также проксимального отдела большеберцовой кости — 148 (18,3%). Наиболее часто используемый тип эндопротеза — неинвазивно удлиняемый — 540 (67%). Было зафиксировано 756 осложнений, частота встречаемости — 96%. В структуре осложнений преобладали онкологические и ортопедические осложнения на фоне роста ребенка — 188 (25%) и 166 (22%) соответственно. Общая выживаемость пациентов за 5 и 10 лет составила в среднем 81,68% и 77,63% соответственно при среднем значении выживаемости эндопротеза 53,93% за десятилетний период.</p> <p><bold>Заключение. </bold>Полученные данные свидетельствуют о крайне высокой частоте осложнений при онкопротезировании у детей, преимущественно ортопедических, что требует анализа и разработки мер по их предупреждению, а также организационных решений для коррекции данных нарушений.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>arthroplasty</kwd><kwd>oncologic arthroplasty</kwd><kwd>malignant tumors</kwd><kwd>children</kwd><kwd>periprosthetic fractures</kwd><kwd>periprosthetic infection</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эндопротезирование</kwd><kwd>онкопротезирование</kwd><kwd>злокачественные опухоли</kwd><kwd>дети</kwd><kwd>перипротезные переломы</kwd><kwd>перипротезная инфекция</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Большаков Н.А., Артемов А.Ю., Ворочай А.М., Хамин И.Г., Тихонова М.В., Слинин А.С. и др.
