In the general structure of oncological endoprosthetics, primary lesions of the distal tibia are rarely affected. Endoprosthetics of the ankle joint region are associated with characteristic difficulties consisting in soft tissue deficiency and restoration of the biomechanics of the lost joint. The existing scientific volume of the literature data on primary ankle replacement is insignificant. At the moment, there is no experience and clear strategy in revision endoprosthetics of this area, complications remain insufficiently explored.</p><p>Objective. The aim of the study was a discrete analysis of medium- and long-term results, the structure of complications, and functional results in a group of patients after primary and repeated oncological ankle replacement.</p><p>Materials and methods. The study included 20 patients with benign and malignant bone tumors, who from July 2008 to November 2019 underwent 33 primary and revision replacements in case of distal tibia tumor lesion. In the study group of patients, 70 % were diagnosed with a primary malignant tumor and 30 % had a benign lesion of the tibia. The mean follow-up period was 58,6 months.</p><p>Results. The leading complication after primary and revision endoprosthetics was early aseptic instability (type IIA) – 20,0 and 23,1 %, respectively. Primary and revision endoprosthetics survival after 5 years was 40,1 ± 12 %.</p><p>Conclusion. The average functional result after primary and revision ankle replacement was evaluated according to the MSTS scale and after 6 months was 70,5 % and varied from 40 to 87 %. After 12 months, this figure was 76 % and ranged from 46,7 to 96,7 %.</p><p>The choice of an endoprosthesis, taking into account the optimal biomechanics design of the endoprosthesis unit, methods of fixation, the introduction of innovative technological solutions in the design, materials of the endoprosthesis, adherence to the principle of radicalism will become a means of reducing the frequency of complications.</p></abstract><trans-abstract xml:lang="ru"><p>Введение. В общей структуре онкологического эндопротезирования поражение первичными опухолями дистального отдела большеберцовой кости возникает достаточно редко. Проведение эндопротезирования области голеностопного сустава сопряжено с характерными трудностями, заключающимися в дефиците мягких тканей и восстановлении биомеханики утраченного сустава. Существующий научный потенциал литературных данных первичного эндопротезирования голеностопного сустава незначительный. В настоящий момент отсутствуют опыт и стратегия повторного онкологического эндопротезирования этой области, осложнения остаются малоизученными.</p><p>Цель исследования – дискретный анализ среднесрочных и отдаленных результатов, структуры осложнений, функционального результата в группе пациентов после первичного и повторного онкологического эндопротезирования голеностопного сустава.</p><p>Материалы и методы. В исследование включено 20 пациентов с доброкачественными опухолями кости и первично локализованными саркомами кости, которым в период с июля 2008 по ноябрь 2019 г. выполнены 33 первичные и повторные операции при поражении дистального отдела большеберцовой кости. В исследуемой группе пациентов 70 % имели диагноз «первичная злокачественная опухоль кости», 30 % – «доброкачественное поражение большеберцовой кости». Средний период наблюдения составил 58,6 мес.</p><p>Результаты. Ведущим осложнением после первичного и повторного эндопротезирования была ранняя асептическая нестабильность (тип IIА) – 20,0 и 23,1 % соответственно. Осложнения типа I–IV по ISOLS 2013 отсутствовали через 5 лет в 40,1 ± 12 % случаев после операций в объеме первичного и повторного эндопротезирования.</p><p>Заключение. Средний функциональный результат после первичного и повторного эндопротезирования голеностопного сустава оценивался по шкале MSTS, он составил через 6 мес 70,5 % и варьировал от 40 до 87 %. Через 12 мес этот показатель составил 76 % и варьировал от 46,7 до 96,7 %.</p><p>Выбор эндопротеза с учетом оптимальной биомеханики конструкции узла эндопротеза, способов фиксации, внедрение инновационных технологических решений в его дизайн, материалы эндопротеза, соблюдение принципа радикальности обеспечат снижение частоты осложнений.</p></trans-abstract><kwd-group xml:lang="en"><kwd>bone tumor</kwd><kwd>ankle joint</kwd><kwd>primary endoprosthetics</kwd><kwd>revision endoprosthetics</kwd><kwd>individual endoprosthetics</kwd><kwd>endoprosthetics complications</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>опухоль кости</kwd><kwd>голеностопный сустав</kwd><kwd>первичное эндопротезирование</kwd><kwd>реэндопротезирование</kwd><kwd>индивидуализированное эндопротезирование</kwd><kwd>осложнения эндопротезирования</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
