Ewing's sarcoma is not less complex disease, which can be explained by its biological characteristics, including aggressive course, a tendency to develop early hematogenous metastases and frequent relapses.<italic>The aim of the study</italic> – checking the possibility of complications, the level of restoration of functions according to the Toronto Extremity Salvage Score (TESS) and Musculoskeletal Tumor Society (МSTS) scales after endoprosthesis, and the installation of a spacer.<italic>Materials and methods.</italic> We analyzed clinical cases of 7 children aged 8 to 15 years, who received treatment at the N.N. Blokhin National Medical Research Center of Oncology, оf the Ministry of Health of Russia in the period 2013–2019. Osteosarcoma was diagnosed in 4 patients, and Ewing’s sarcoma in 3 patients. They underwent organ-preserving surgical treatment of the upper limb in one of three ways – endoprosthesis, placement of a spacer, and replacement with autologous bone on microvascular anastomoses. In the course of the study, a method was used to assess limb function according to the TESS and МSTS scales.<italic>Results. </italic>It was found that in the postoperative period in all patients, regardless of the applied method of organ-preserving surgery, the results varied within 1,4–1,5 on the TESS scale, and 91–95 % on the MSTS scale. Postoperative complications in the form of post-traumatic neuropathy and dislocation were identified in 4 patients. 1 patient had local recurrence, 1 patient was diagnosed for metastatic leisure of lung tissue. It should be noted that the condition of all patients is currently satisfactory, no lethal cases have been identified.<italic>Conclusion. </italic>We believe that the results of this study are promising. However, it is necessary to conduct a longer period of observation of patients and evaluate their 5-year survival.</p></abstract><trans-abstract xml:lang="ru"><p><italic>Введение.</italic> Остеосаркома – крайне злокачественная мезенхимальная, высокодифференцированная опухоль из костной ткани, протекающая агрессивно, характеризующаяся быстрым развитием удаленных метастазов. Саркома Юинга – не менее сложное заболевание, что объясняется его биологическими особенностями, в том числе агрессивным течением, склонностью к развитию ранних гематогенных метастазов и частых рецидивов.<italic>Цель исследования</italic> – проверка возможности возникновения осложнений и уровня восстановления функций по шкалам  Toronto Extremity Salvage Score (TESS) и Musculoskeletal Tumor Society (МSTS) после эндопротезирования и установки  спейсера.<italic>Материалы и методы.</italic> Нами были рассмотрены клинические случаи 7 детей в возрасте от 8 до 15 лет, получавших  лечение в НИИ ДОИГ ФГБУ «Научный медицинский исследовательский центр онкологии им Н.Н. Блохина» Минздрава  России в 2013–2019 гг. У 4 пациентов был установлен диагноз остеосаркомы, у 3 – саркомы Юинга. Им было проведено  органосохраняющее хирургическое лечение верхней конечности одним из 3 способов: эндопротезирование, установка спейсера и замещение аутокостью на микрососудистых анастомозах. В ходе исследования использовалась методика оценки функции конечности по шкалам TESS и МSTS.<italic>Результаты.</italic> Было выявлено, что в послеоперационный период у всех пациентов вне зависимости от примененной методики органосохраняющей операции результаты варьировались в пределах 1,4–1,5 по шкале TESS, и 91–95 % по шкале MSTS. У 4 пациентов выявлены послеоперационные осложнения в виде посттравматической нейропатии и вывиха. У 1 больного был диагностирован местный рецидив, у 1 – метастатическое поражение легочной ткани. Следует  отметить, что состояние всех пациентов на данный момент удовлетворительное, летальных случаев выявлено не было.<italic>Заключение. </italic>Мы считаем, что результаты проведенного исследования многообещающие. Однако необходимо осуществить более длительное наблюдение за пациентами и оценить их 5-летнюю выживаемость.</p></trans-abstract><kwd-group xml:lang="en"><kwd>surgery</kwd><kwd>osteosarcoma</kwd><kwd>pediatrics</kwd><kwd>endoprosthetics</kwd><kwd>autotransplantation</kwd><kwd>Ewing’s sarcoma</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хирургия</kwd><kwd>остеосаркома</kwd><kwd>педиатрия</kwd><kwd>эндопротезирование</kwd><kwd>аутотрансплантация</kwd><kwd>саркома Юинга</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bacci G., Ferrari S., Mercuri M. et al.
