The development of 3D printing technology allows the manufacture of individual implants to treat the patients with diseases and consequences of musculoskeletal system injuries. However, the use of additive technologies in the patients with multiple trauma in the acute period is limited. The purpose of study was to demonstrate the possibility of using individual implants for the definitive fixation of the anterior pelvic ring in a patient with multiple trauma.</p><p><bold>Patient concerns</bold>. A 22-year-old patient was admitted after an injury as a result of a fall from the 5<sup>th</sup> floor. The treatment was carried out in accordance with the ATLS protocol. Diagnosis: multiple trauma; closed chest, pelvis and limbs injuries; fracture of the left 2nd to 5th ribs; pelvic bones fracture AO/ OTA: 61-C1.3a; fracture of both bones of the left lower leg AO/OTA: 42-B3b; 2nd degree shock.</p><p><bold>Interventions</bold>. An emergency external fixation of the pelvis and lower leg bones was performed. An individual implant for pubic bone fixation was made using 3D printing. On the 8th day, the definitive fixation of the pelvic and left lower leg bones was performed. The patient is activated on the 1st day after the surgery.</p><p><bold>Outcomes</bold>. The early postoperative period was uneventful. The functional result on the Majeed scale in 6 months by remote filling out the questionnaire was 84 points. Lessons. The custom-made implants make it possible the successful fixation of the anterior pelvic ring. The use of 3D printing technologies for the osteosynthesis of pelvic fractures is promising, although requires further study.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность</bold>. Развитие технологий 3D-печати позволяет изготавливать индивидуальные имплантаты для лечения пациентов с заболеваниями и последствиями повреждений опорно-двигательной системы. Однако использование аддитивных технологий у пациентов с политравмой в остром периоде ограничено.</p><p><bold>Цель исследования</bold> — продемонстрировать возможность применения индивидуальных имплантатов для окончательной фиксации переднего отдела тазового кольца у пациента с политравмой.</p><p><bold>Клиническое наблюдение</bold>. Пациент 22 лет поступил на лечение после получения кататравмы в результате падения с 5-го этажа. Лечение по протоколу ATLS. Диагноз: политравма; закрытая травма грудной клетки, таза, конечностей; перелом II–V ребер слева; перелом костей таза АО/ОТА: 61-C1.3a; перелом обеих костей левой голени АО/ ОТА: 42-B3b; шок 2 ст. В экстренном порядке выполнена фиксация костей таза и левой голени в аппарате внешней фиксации. Методом 3D-печати изготовлен индивидуальный имплантат для фиксации лонной кости. На 8-е сутки выполнена окончательная фиксация костей таза и левой голени. Пациент активизирован в 1-е сут. после операции. Ранний послеоперационный период протекал без осложнений. Функциональный результат по шкале Majeed путем дистанционного заполнения опросника через 6 мес. — 84 балла.</p><p><bold>Заключение</bold>. Использование индивидуально изготовленных имплантатов позволяет успешно выполнять фиксацию переднего отдела тазового кольца. Применение технологий 3D-печати при остеосинтезе переломов костей таза является перспективным, но требует дальнейшего изучения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>multiple trauma</kwd><kwd>pelvic bones fracture</kwd><kwd>external fixation of the pelvis</kwd><kwd>additive technologies</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>политравма</kwd><kwd>перелом костей таза</kwd><kwd>аддитивные технологии</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
