Material and methods: 119 patients with 134 ASR XL head - Corail prostheses were treated in 2007-2009. The results were studied in 94 cases (105 prostheses) - 84%. Average follow-up time consisted 62 ± 3 months. MRI was performed in 12 patients (13 hips) who had clinical nonsatisfaction. Obtained data were compared with 21 MRI (24 hips) of controlled group with good and perfect clinical results. Results. We found variations of normal periprosthetic tissue condition. Adverse reactions were identified in 10 cases. To improve the quality of pictures we developed special MRI adjustments and regimes of work. Conclusion: MRI diagnostics is indicated for the patients with metal-on-metal total hip arthroplasty in order to identify adverse local tissue reactions. The improvement of picture quality needs special adjustment of MRI equipment.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования - диагностика изменений в перипротезных тканях у пациентов после замещения тазобедренного сустава эндопротезами с парой трения металл-металл и головками большого диаметра. Материал и методы. С 2007 по 2009 г. 119 пациентам имплантировано 134 эндопротеза тазобедренного сустава ASR XL head - Corail. Результаты эндопротезирования изучены у 94 пациентов (105 суставов или 81,4 %). Средний срок наблюдения - 62±3 месяца. МРТ выполнена 12 пациентам (13 эндопротезов), результаты были сопоставлены с результатами МРТ контрольной группы, которую составил 21 больной с 24 аналогичными эндопротезами, не имеющий жалоб и клинических отклонений. Результаты. Определён вариант нормального состояния перипротезных тканей. Выявлены изменения вокруг 10 эндопротезов. Разработаны настройки для сканирующего оборудования, улучшающие качество изображения. Выводы. Для дифференцирования патологического процесса пациентам после тотальной артропластики тазобедренного сустава с парой трения металл-металл показано выполнение магнитно-резонансной томографии. Для повышения информативности МРТ необходимы специальные настройки томографа.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эндопротезирование</kwd><kwd>осложнения</kwd><kwd>псевдоопухоль</kwd><kwd>магнитно-резонансная томография</kwd><kwd>пара трения металл-металл</kwd><kwd>hip replacement</kwd><kwd>complications</kwd><kwd>pseudotumor</kwd><kwd>MRI</kwd><kwd>ASR XL heads</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Имплантаты хирургические неактивные.
