Acetabular defects are becoming more frequent, with Paprosky type IIIA and above becoming more common. Recently, customized 3D-printed constructs have been used to remodel severe defects. We wanted to demonstrate the possibility of treating a patient with a severe acetabular defect by performing a one-stage revision endoprosthesis using a customized design.</p> <p><bold><italic>CLINICAL CASES DESCRIPTION</italic></bold><italic>: </italic>A 69-year-old patient underwent primary total hip replacement of the right hip joint with a Biomet endoprosthesis for coxarthrosis in 2010. In 2011 — on the left side with a Zimmer endoprosthesis. In 2013 — revision endoprosthesis of the right hip joint due to instability was preformed. In the postoperative period, there were repeated dislocations with subsequent closed repositioning. In 2015, revision endoprosthetic replacement with a Burkh-Schneider antiprotrusion ring was done for recurrent dislocation. In november 2017, she was diagnosed with instability of the right total hip joint, for which she underwent revision hip replacement with a customized acetabular component.</p> <p>HHS score before revision arthroplasty was 18 points, 1 month after surgery — 75 points, after 3 months — 65, after 6 months — 82, after 4 years — 74. Quality of life was assessed using the WOMAC scale: 92 points before surgery, 38 points 1 month after surgery, 31 points in 3 months, 15 points in 6 months, and 35 points in 4 years. As of the last visit, the patient moves with a cane, and still has a limp due to scar remodeling and gluteal muscles atrophy.</p> <p><bold><italic>CONCLUSION</italic></bold><italic>:</italic> In case of severe acetabular defects, the use of individual components allows achieving reliable "implant–bone" fixation, which leads to improved functional results. However, in chronic pelvic bone integrity defects, the use of an individual acetabular component does not always achieve reliable stabilization. All existing methods for solving this problem are currently ambiguous and require further improvement.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Число тотальных замещений тазобедренного сустава растёт с каждым годом. Чаще встречаются дефекты вертлужной впадины, при этом дефекты типа IIIА по Paprosky и выше становятся всё более распространёнными. В последние годы для реконструкции тяжёлых дефектов применяются индивидуальные конструкции, созданные с помощью 3D-печати. На этом клиническом примере показана возможность лечения пациентки с тяжёлым дефектом вертлужной впадины путём проведения одноэтапного ревизионного эндопротезирования с использованием индивидуальной конструкции.</p> <p><bold>Описание клинического случая</bold>. Пациентке 69 лет по поводу коксартроза в 2010 г. выполнено первичное тотальное эндопротезирование правого тазобедренного сустава эндопротезом компании Biomet. В 2011 г. — слева эндопротезом фирмы Zimmer. В 2013 г. — ревизионное эндопротезирование правого тазобедренного сустава по поводу нестабильности. В послеоперационном периоде отмечались неоднократные вывихи с последующими закрытыми вправлениями. В 2015 г. по поводу рецидивирующего вывиха выполнено ревизионное эндопротезирование с установкой антипротрузионного кольца Бурх–Шнайдера. В ноябре 2017 г. выявлена нестабильность тотального эндопротеза правого тазобедренного сустава, по поводу чего выполнено ревизионное эндопротезирование с применением индивидуального вертлужного компонента.</p> <p>Показатель HHS до ревизионного эндопротезирования составил 18 баллов, через 1 мес после операции — 75 баллов, через 3 мес — 65, через 6 мес — 82, через 4 года — 74. Качество жизни оценивали по шкале WOMAC: до операции — 92 балла, через 1 мес после операции — 38 баллов, через 3 мес — 31, через 6 мес — 15, через 4 года — 35 баллов. На момент последней консультации пациентка передвигается с тростью, сохраняется хромота, связанная с рубцовой перестройкой и атрофией ягодичных мышц.</p> <p><bold>Заключение</bold>. При выраженных дефектах вертлужной впадины применение индивидуальных компонентов позволяет достичь надёжной фиксации «имплантат–кость», что приводит к улучшению функциональных результатов. Однако при хроническом нарушении целостности тазовой кости применение индивидуального вертлужного компонента не всегда позволяет достичь надёжной стабилизации. Все существующие методы для решения данной проблемы на сегодняшний день являются неоднозначными и требуют дальнейшего усовершенствования.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hip joint</kwd><kwd>revision arthroplasty</kwd><kwd>individual design</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тазобедренный сустав</kwd><kwd>ревизионное эндопротезирование</kwd><kwd>индивидуальная конструкция</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">Kurtz S, Ong K, Lau E, Mowat F, Halpern M.
