Unstable, comminuted fractures pose a particular difficulty, requiring not only early stabilization but also precise anatomical reductiоn of all elements of the pelvic ring.</p> <p>Achieving proper fragment alignment, especially in cases of vertical and rotational displacement, remains a complex task. Open surgical approaches are associated with significant blood loss, risk of damage to neurovascular structures, and infectious complications, highlighting the need for the development of minimally invasive techniques.</p> <p>This article describes the clinical experience of intraoperative application of a pelvic reduction frame for anatomical reduction in a comminuted pelvic fracture, as well as an assessment of rehabilitation outcomes, long-term functional results, and patient quality of life.</p> <p>We present a clinical case оf a 39-year-old patient who sustained multiple pelvic fractures due to a fall from height. The article demonstrates the use оf an intraoperative pelvic reduction frame (hereinafter referred to as the “pelvic frame”) during closed reduction and osteosynthesis of the pelvic ring, which facilitated early patient verticalization and led to good functional outcomes (Majeed score 88, Oxford Hip Score 52).</p> <p>This clinical case confirms the effectiveness of using a pelvic frame in the treatment of complex, vertically unstable pelvic fractures. The methоd provided accurate closed reduction and stable fixation without the need for extensive surgical approaches. This, in turn, enabled early mobilization and a favorable long-term functional result.</p></abstract><trans-abstract xml:lang="ru"><p>Высокоэнергетические переломы костей таза — сложная проблема современной травматологии и ортопедии, связанная с высоким риском кровопотери, тромбоэмболии, неврологических нарушений и длительной утраты функции. Особую трудность представляют нестабильные оскольчатые переломы, при которых требуется не только ранняя стабилизация, но и точная анатомическая репозиция всех элементов тазового кольца.</p> <p>Достижение правильного положения отломков, особенно при вертикальных и ротационных смещениях, остаётся сложной задачей. Открытые доступы сопряжены с высокой кровопотерей, риском повреждения сосудисто-нервных структур и инфекционных осложнений, что повышает актуальность развития малоинвазивных методов.</p> <p>В данной статье описан клинический опыт интраоперационного применения тазовой рамы для анатомичной репозиции при многооскольчатом переломе костей таза, а также оценены результаты реабилитации, отдалённые функциональные исходы и качество жизни пациента.</p> <p>Представлен клинический случай лечения 39-летнего пациента, получившего множественные переломы костей таза в результате падения с высоты. В работе продемонстрировано использование интраоперационной тазовой рамы (далее — «тазовая рама») при выполнении закрытой репозиции и остеосинтеза тазового кольца, что способствовало ранней вертикализации пациента и привело к хорошим функциональным исходам (по шкале Majeed — 88, по шкале Oxford Hip Score — 52).</p> <p>Данный клинический случай подтверждает эффективность применения тазовой рамы при лечении сложных, вертикально-нестабильных переломов костей таза. Метод обеспечил точную закрытую репозицию и стабильную фиксацию без необходимости расширенных хирургических доступов. Это в свою очередь позволило достичь ранней активизации и благоприятного отдалённого функционального результата.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pelvic fracture</kwd><kwd>closed reduction</kwd><kwd>comminuted sacral fracture</kwd><kwd>pelvic osteosynthesis with plate and screws</kwd><kwd>pelvic external fixation frame</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>перелом костей таза</kwd><kwd>закрытая репозиция</kwd><kwd>оскольчатый перелом крестца</kwd><kwd>остеосинтез костей таза пластиной и винтами</kwd><kwd>тазовая рама внешней фиксации</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Pereira GJC, Damasceno ER, Dinhane DI, et al.
