В применяемых в настоящее время эндопротезах головки тазобедренного сустава конструктивные особенности системы крепления чашки в вертлужной впадине тазовой кости не обеспечивают достаточной стабильности имплантанта. Не исключается возможность в процессе эксплуатации самопроизвольного выворачивания головки эндопротеза из кости. Достаточно серьезна вероятность выхода из строя шарового гнезда, изготовленного из полиэтилена, под воздействием ударных нагрузок. Предлагаемая конструкция эндопротеза головки тазобедренного сустава имеет своей целью повышение надежности установки и крепления чашки в вертлужной впадине реципиента, а также улучшение условий работы трущихся поверхностей шарового сочленения.In currently used hip joint endoprostheses, the design features of the cup anchoring system in the acetabulum of the pelvic bone do not provide sufficient implant stability. It does not exclude the possibility of spontaneous eversion of the endoprosthesis head out of the bone during operation. The probability of failure of a spherical socket made of polyethylene under the influence of shock loads is quite serious. The proposed design of the endoprosthesis of the head of the hip joint is aimed at improving the reliability of mounting and fixing the cup in the acetabulum of the recipient, as well as improving the working conditions of the rubbing surfaces of the ball joint.
