Although magnesium screws have demonstrated favorable clinical outcomes, their mechanical properties have not been sufficiently evaluated.</p> <p><bold>AIM:</bold> The work aimed to perform a comparative analysis of the physicomechanical properties of Herbert screws made of bioresorbable MgYREZr magnesium alloy produced by Russian and international manufacturers.</p> <p><bold>METHODS: </bold>This was a prospective, pilot, multicenter, experimental study of Herbert screws made of MgYREZr alloy manufactured by Syntellix AG (Hannover, Germany) and Osteo-Sibear LLC (Moscow, Russia), with a consecutive sample of eleven screws. The study was experimental and involved the accumulation of both quantitative and qualitative data. The control included both descriptive assessment and precise measurements with before/after comparison. During testing, processes simulating displacement of bone structures were modeled. Herbert screws were fixed in polyurethane blocks manufactured according to the ASTM F1839 standard and tested using a universal testing machine (Walter+Bai AG LFM-50). The setup was used to simulate pull-out, shear failure, and stripping of the screw head.</p> <p><bold>RESULTS: </bold>The mean pull-out force for the polymer block fixed with the Osteo-Sibear screw was 301.33 N, whereas 160 N was required to disrupt fixation with the Syntellix AG screw. To induce displacement of the polymer block fixed with the Osteo-Sibear screw, a force of approximately 298.5 N was required, whereas the corresponding fixation with the Syntellix AG screw failed at 295 N. The mean torque required to cause screw head slot stripping was 0.23 Nm for the Osteo-Sibear screw and 0.36 Nm for the Syntellix AG screw.</p> <p><bold>CONCLUSION:</bold><bold> </bold>The Russian Herbert screw demonstrated superior fixation strength in pull-out and shear tests. Under torsional loading, the screw head slot failed, with the screw body remaining intact.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Магниевые биорезорбируемые сплавы, применяющиеся для изготовления фиксаторов, существенно уступают по механической прочности титановым аналогам ввиду аналогичных прочностных характеристик с костной тканью. Магниевые винты имеют хорошие результаты клинического применения, однако анализ механических свойств не проводился.</p> <p><bold>Цель.</bold> Сравнительный анализ физико-механических свойств винтов Герберта из резорбируемого магниевого сплава MgYREZr отечественного и зарубежного производства.</p> <p><bold>Методы.</bold> Проведено проспективное пилотное многоцентровое исследование; объект — винты Герберта из сплава MgYREZr компаний Syntellix AG (Ганновер, Германия) и «Остео-Сайбэр» (Москва, Россия) при сплошной выборке одиннадцати образцов. Исследование экспериментальное, с получением количественных и качественных данных. Контроль исследования носит как описательный характер, так и точные значения с учётом «до / после». Во время испытаний были смоделированы процессы, при которых происходит смещение костных структур. Винты Герберта были закреплены в полиуретане, изготовленном по стандарту ATSM1839, и помещены в универсальную испытательную машину (Walter+Bai AG LFM-50), при помощи которой были смоделированы процессы разрыва, сдвига соединения и деструкции шлица винта.</p> <p><bold>Результаты. </bold>Среднее значение силы деструкции для вырывания полимерного блока, скреплённого винтом «Остео-Сайбэр», составило 301,33 Н, в то время как для разрыва соединения винтом Syntellix AG необходимо приложить 160 Н. Для смещения полимерного блока, скреплённого винтом «Остео-Сайбэр», необходимо усилие около 298,5 Н, при этом аналогичное соединение винтом Syntellix AG разрушалось при 295 Н. Для срыва шлица винта «Остео-Сайбэр» среднее значение составило 0,23 Нм, для винта Syntellix AG потребовалось 0,36 Нм.</p> <p><bold>Заключение. </bold>Отечественный винт Герберта обладает более прочными фиксирующими свойствами в испытаниях на разрыв и сдвиг соединения. При торсионном воздействии деструкции подвергается шлицевое соединение при сохранном теле винта.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Herbert screw</kwd><kwd>biodegradable magnesium alloy</kwd><kwd>pull-out test</kwd><kwd>torsional properties</kwd><kwd>fracture fixation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>винт Герберта</kwd><kwd>биорезорбируемый магниевый сплав</kwd><kwd>испытание на вырывание</kwd><kwd>торсионные свойства</kwd><kwd>фиксация перелома</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>May H, Alper Kati Y, Gumussuyu G, et al.
