摘要：
It can be used in total hip replacement. The technical result - providing stable operation under high load and improvement of reliability of fastening the head insert through - with a cup and through the neck - with a leg, and to provide an anatomically correct ratio between the pelvis and femur, with an improvement of the interchangeability of the elements of the endoprosthesis multilink connection. This is achieved by making the end of the cervix, coupled with the leg in the form of a symmetrical tetrahedron with two parallel faces and the other two edges symmetrical frusto partial-conical, with a conicity equal to 3,7 °, with respect to the length of the end of the neck to the length of the end bonded the head and neck to the length, sootvetstvlyayuschem: 15: 12: 55.5 ÷ 56.6, in the performance of the liner with a semicircular protrusion on the end face for enhanced coverage of the head liner with a protrusion height of 0.09 ÷ 0.14 of the diameter of the head in made. surface of the liner and the conjugate, the plate surface in the form of three mating surfaces truncated cones, passing from one to another, and is made, the bottom surface is separated from the track. annular rim surface on the insert and the mating circumferential groove on the plate at a height lower surface, making up. 9/11 of the height of the insert by the projection. The end collar, integrated with the head, mb It is inclined in the frontal plane at an angle of 8 °, relative to the end of the neck, fastened to the foot. The end collar, integrated with the head, mb tilted relative to the end, is secured, with the leg at an angle of 8 ° in the plane perpendicular to the frontal plane. The end collar, integrated with the head, mb simultaneously tilted relative to the quadrangular end fastened to the foot, in two planes, respectively, in the frontal plane and in a plane perpendicular to the front.Может быть использован при эндопротезировании тазобедренных суставов.
