Abstract

Изобретение относится к медицине, а именно к травматологии и ортопедии, и позволяет достичь надежной фиксации имплантата в костной ткани в начальный момент и в отдаленные сроки, а также обеспечить прочное срастание пористой поверхности чашки с костной тканью человека за счет создания, благодаря конструктивным особенностям протеза, стабильных условий для микроциркуляции физиологической жидкости в зоне контакта пористого покрытия и костной ткани вертлужной впадины и глубокого прорастания костной ткани в пористое покрытие чашки по всему объему пористого покрытия. Пористое покрытие выполнено из спрессованных пористых блоков вспененного чистого титана и представляет собой форму полусферического свода с толщиной стенки не менее 2 мм, закрепленного на внешней полусферической поверхности чашки протеза бедра методом запрессовки в кольцевую проточку у нижней части чашки. На полусферическую поверхность чашки нанесен рельеф в виде концентрических или спиралевидной канавок глубиной 0,5-1,5 мм.The invention relates to medicine, namely to traumatology and orthopedics, and allows you to achieve reliable fixation of the implant in the bone tissue at the initial moment and in the long term, as well as to ensure durable accretion of the porous surface of the cup with human bone tissue due to the design, stable conditions for microcirculation of physiological fluid in the zone of contact of the porous coating and the bone tissue of the acetabulum and deep sprouting of the bone tissue into the porous coating of the cup over all at the volume of the porous coating. The porous coating is made of compressed porous blocks of foamed pure titanium and is a hemispherical shape with a wall thickness of at least 2 mm fixed to the outer hemispherical surface of the femoral cup by pressing into an annular groove at the bottom of the cup. On the hemispherical surface of the cup there is a relief in the form of concentric or spiral-shaped grooves with a depth of 0.5-1.5 mm.
