A clinical study was conducted in the comparison groups. In the main group (50 patients), we used the proposed method in the pre-operative planning; in the control group the patients were prepared for the operation using a standard planning method. The accuracy of evaluation of implant sizes, limb length and offset were registered in the post-operative period. The preoperative planning data were compared with the results obtained.</p> <p><bold>Results. </bold>The accuracy of offset estimation in the main group was higher than in the control group (T-criterion = -2.6; p = 0.01). The average difference between the estimated offset and the one obtained in the main group was 1.4±1.5 mm, in the control group it was 2.2±1.7 mm. The error in head size estimation in the main group was less than in the control group (odds ratio = 3.02). No significant differences were registered in determining the size of components of the endoprosthesis, and there were no differences in the leg length in the study groups.</p> <p><bold>Conclusion. </bold>The developed method allows for improving the accuracy of preoperative planning in hip arthroplasty. The proposed device ensures the correct placement of patients when performing pelvic radiography, and also makes it easy to change it when performing this procedure.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель</bold> – провести сравнительную оценку точности разработанного способа предоперационного планирования при первичном эндопротезировании тазобедренного сустава.</p> <p><bold>Материал и методы.</bold> Для повышения точности предоперационного планирования и уменьшения количества интра- и послеоперационных осложнений был разработан «Способ предоперационного планирования при эндопротезировании тазобедренного сустава» и устройство для его реализации. Проведено клиническое исследование в группах сравнения. В основной группе (50 пациентов) подготовку к операции осуществляли с применением предложенного способа, в контрольной – с использованием стандартной методики планирования. В послеоперационном периоде оценивали точность определения размеров компонентов эндопротезов, длины конечности, офсета. Для этого сравнивали данные предоперационного планирования и полученные результаты.</p> <p><bold>Результаты. </bold>Точность оценки офсета в основной группе была выше, чем в контрольной (Т-критерий = -2,6; p = 0,01). Средняя разница между предполагаемым офсетом и полученным в основной группе составила 1,4±1,5 мм, в контрольной – 2,2±1,7 мм. Погрешность в оценке размера головки в основной группе была меньше, чем в контрольной (отношение шансов = 3,02). Достоверных отличий определения размеров вертлужного и бедренного компонентов эндопротеза, разницы в длине конечностей в группах сравнения не было.</p> <p><bold>Заключение.</bold> Разработанный способ позволяет повысить точность предоперационного планирования при эндопротезировании тазобедренного сустава. Предложенное устройство обеспечивает правильную укладку пациентов при выполнении рентгенографии таза, а также позволяет легко изменять ее при выполнении данной процедуры.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hip arthroplasty</kwd><kwd>preoperative planning</kwd><kwd>complications</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эндопротезирование тазобедренного сустава</kwd><kwd>предоперационное планирование</kwd><kwd>осложнения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Guide to hip replacement.
