To analyze the current capabilities of three-dimensional printing in the surgical management of pelvic and hip bone defects, we reviewed scientific literature available in open-access databases including PubMed, eLibrary.Ru, Scopus, and Dimensions, with a search depth of up to 10 years. This review highlights major trends and advances in the medical application of 3D technologies aimed at reducing perioperative risks and improving patients’ quality of life in the context of bone tissue defects. Particular focus is placed on revision hip arthroplasty and pelvic oncologic conditions, where modern additive manufacturing technologies can enhance treatment quality and surgical outcomes. The methodology of 3D scanning for designing patient-specific implants is described. The review also demonstrates current and promising applications of 3D printing in clinical practice. Modern 3D technologies, particularly additive manufacturing, play an important role in improving surgical outcomes for skeletal deficiencies by enabling personalized treatment, expediting recovery, and improving patient prognosis. Emerging directions significantly expand the range of available reconstructive procedures, reduce the risk of complications, and ultimately improve patient quality of life and surgical efficiency.</p></abstract><trans-abstract xml:lang="ru"><p>Применение 3D-технологий позволяет достичь более точного планирования оперативных вмешательств в сложных случаях локального дефицита костной ткани, адаптировать их к анатомическим особенностям конкретного пациента, улучшая прогноз и снижая риск возможных осложнений, ускорить результаты восстановления пациентов в послеоперационном периоде. Для анализа информации о современных возможностях трёхмерной печати при оперативном лечении дефектов костной ткани таза, тазобедренного сустава мы использовали данные открытых электронных баз научной литературы PubMed, eLibrary.Ru, Scopus, Dimensions глубиной поиска до 10 лет. В обзоре рассмотрены основные тенденции и достижения в направлении использования 3D-технологий в медицине, способствующие снижению периоперационных рисков и улучшению качества жизни пациентов при дефектах костной ткани. Взгляд сфокусирован на проблеме ревизионного эндопротезирования тазобедренного сустава и онкологической патологии таза с возможностью применения современных аддитивных технологий с целью повышения качества лечения и результативности вмешательств. Описана методика 3D-сканирования для создания индивидуальных имплантатов. Продемонстрированы перспективы использования 3D-печати, актуальные способы применения аддитивных технологий в практической медицине. Современные 3D-технологии играют значительную роль в совершенствовании результатов хирургического вмешательства при дефиците костного скелета: аддитивные технологии позволяют индивидуализировать лечебный процесс, ускоряя выздоровление и улучшая прогноз пациента в будущем. Появляются перспективные направления, значительно расширяющие спектр проводимых реконструктивных операций, снижающие риски возникновения осложнений, что улучшает качество жизни пациентов и оптимизирует деятельность хирурга.</p></trans-abstract><kwd-group xml:lang="en"><kwd>bone tissue defects</kwd><kwd>revision hip arthroplasty</kwd><kwd>3D technologies</kwd><kwd>3D printing</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дефекты костной ткани</kwd><kwd>ревизионное эндопротезирование тазобедренного сустава</kwd><kwd>3D-технологии</kwd><kwd>3D-печать</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Nagibovich OA, Svistov DV, Peleshok SA, et al.
