摘要：
The utility model relates to medical equipment and can be used in traumatology and orthopedics to replace a deformed or destroyed acetabulum during primary and revision hip arthroplasty. The acetabular component of the hip endoprosthesis is made in the form of a cup to replace acetabular defects with a porous outer coating and with through threaded holes for spongy screws. The holes have longitudinal axes intersecting at a point coinciding with the common center of bends of the outer and inner surfaces of the cup. The cup is equipped with a safety flange and is made with internal annular grooves for distribution of the cement mantle, with a threaded hole for the installation tool and with a porous coating having a trabecular structure. The holes for the spongy screws are located at the boundaries of the spherical layer and are made with internal mechanical recesses for the screw heads. The recesses for the screw heads are shaped to deflect the screws at an angle of at least 15 °. At the ends of the recesses for the screw heads, threaded holes for the plugs are made. The angle between the longitudinal axes of the holes at the boundary of the spherical layer of small diameter is at least 10 ° greater than the angle between the longitudinal axes of the holes at the boundary of the spherical layer of large diameter. The technical result of the utility model is to increase the survival time of the acetabular cup during primary and revision hip arthroplasty.Полезная модель относится к медицинской технике и может быть использована в травматологии и ортопедии для замещения деформированной или разрушенной вертлужной впадины при первичном и ревизионном эндопротезировании тазобедренного сустава. Вертлужный компонент эндопротеза тазобедренного сустава выполнен в виде чашки для замещения дефектов вертлужной впадины с пористым наружным покрытием и со сквозными резьбовыми отверстиями для спонгиозных винтов. Отверстия имеют продольные оси, пересекающиеся в точке, совпадающей с общи
