Доступные методы фиксации ПШБК рассмотрены с точки зрения биомеханической стабильности.</p><p>Проведено биомеханическое исследование стабильности остеосинтеза ПШБК тремя канюллированными спонгиозными винтами с применением синтетических моделей проксимального отдела БК. Экспериментальные модели были распределены на 4 группы. Каждая группа соответствовала определенной конфигурации взаимного расположения винтов в ШБК. Эксперимент проводился в двух сериях. В І серии модели подвергались вертикальной нагрузке, во ІІ серии – горизонтальной нагрузке. Действие силы фиксировали при смещении отломков на 2 мм. Наилучшие показатели прочности фиксации получены в І группе в обеих сериях – 1898 Н при вертикальной нагрузке и 1046 Н при горизонтальной нагрузке. Далее в убывающем порядке получены результаты стабильности во ІІ, ІІІ и IV группах.</p><p>В процессе эксперимента установлено, что триангулярное расположение винтов c учетом архитектоники ШБК, каждый из которых имеет три точки соприкосновения с компактной костной тканью, обеспечивает максимальную стабильность конструкции при остеосинтезе переломов ШБК, что сопоставимо с нагрузкой в обычных условиях ходьбы.</p><p>Мы полагаем, что при остеосинтезе ПШБК три винта могут создать лучшую стабильность, если они расположены в плотных тканях проксимального отдела бедренной кости с учетом особенностей архитектоники кости. Для обеспечения максимальной стабильности каждый винт должен иметь три точки контакта с компактной костью – латеральная кортикальная стенка подвертельной области БК, внутренняя стенка ШБК и компактная часть головки БК. Новая треугольная конфигурация установки винтов могла бы лучше нейтрализовать срезывающие силы при ПШБК.</p></abstract><trans-abstract xml:lang="en"><p>Bone geometry, density, and thickness of the cortical layer of the femoral neck (FN) contribute to the mechanical strength in osteosythesis of femoral neck fractures (FNF) in young adults. The available techniques for fracture fixation of the FN are reviewed with respect to the biomechanical stability.</p><p>A biomechanical study of the osteosynthesis stability of the FNF with three cannulated screws was carried out using synthetic models of the proximal part of the femoral bone (FB). The experimental models were divided into 4 groups. Each group related to the configuration of screws in the FN. The vertical and horizontal FNF stability was assessed using two series of load. In series I, models were loaded with forces in the longitudinal axis to the FB and in series II, forces acted in the perpendicular direction to the FB axis. The loading forces were evaluated when the displacement of 2 mm fragments was achieved. The highest stability strengths were obtained in group I in the both series ‒ 1898 N with a vertical load and 1046 N with a horizontal load. Further, in decreasing order, the results of stability were obtained in groups II, III and IV.</p><p>In this study, it was found that the consideration of the position of screws according to architectonics of the FN is crucial for fragment stability. The triangular position of screws with three points of contact with the compact bone ensures the maximum stability of the construct in osteosynthesis of the FN fractures, which is comparable to the normal walking load conditions.</p><p>We hypothesize that osteosynthesis of FN fractures with three screws in a triangular manner could provide a better stability when inserted into the dense tissues of the proximal FB with relation to bone architectonics. To ensure a maximum stability, each screw should have three points of contact with the compact bone – the lateral cortical wall of the subtrochanteric region of the FB, the inner wall of the FN, and the compact part of the FB head. New triangular configuration of screws’ placement could have a better neutralization of share forces in FN fractures.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>перелом шейки бедренной кости</kwd><kwd>остеосинтез винтами</kwd><kwd>биомеханика кости</kwd></kwd-group><kwd-group xml:lang="en"><kwd>femoral neck fracture</kwd><kwd>screw osteosynthesis</kwd><kwd>bone biomechanics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Loskutov A.
