摘要： The cup (2) made of a titanium-aluminum alloy is set into the acetabulum. It is thicker on one side (7) than on the opposite side (8). An aperture (17) extends from a center opening (5) of the cup to the rim (20) thereof. At the point of transition of the edges (18, 19) of the aperture to the rim, there are niches (21, 22) for the placement of pincers. This makes it possible to remove a defective insert (11) without damaging the cup or the bone. The cup is provided at its bottom rim with an encircling flange (9) intended to fit into a matching groove (10) of the insert. The cup and the insert come in contact only in this area, thus ensuring optimum introduction of force from the ball head (13) via the insert into the cup.

摘要： A hip joint socket for implantation without cement into the acetabulum of the hip bone, consisting of an elastic socket support, which has the shape of an essentiallly hemispherical shell and can be inserted in an interlocking manner into the correspondingly prepared acetabulum bed. The socket support is formed so that after its implantation it quicklly grows together with the hip bone, and, even with considerable stress, relative movement between the socket support and the acetabulum is prevented. This is attained by constructing the socket support so that it exhibits its greatest stiffness in cranial portion in the implanted state, while in the downward (caudal) direction the elasticity of socket support increases. The wall thickness of socket support is greatest in cranial portion and decreases in the direction toward caudal portion. In the elastic caudal portion of the socket support, two or more notches are provided that run parallel or substantially parallel to the equatorial plane with increased elasticity at different distances from the equatorial plane.
摘要翻译： 一种用于将无水泥植入髋骨的髋臼的髋关节插座，其由弹性插座支撑件组成，其具有基本上半球形外壳的形状，并且可以互锁方式插入到相应制备的髋臼床中。 插座支撑件形成为使得其在植入之后与髋骨一起快速生长，并且即使在相当大的应力下，也可以防止插座支撑件和髋臼之间的相对移动。 这通过构造插座支撑件来实现，使得其在植入状态下在颅部显示出最大的刚度，而在向下（尾端）方向上插座支撑件的弹性增加。 插座支架的壁厚在头部最大，并且朝向尾部方向减小。 在插座支撑件的弹性尾部，提供两个或更多个凹槽，其平行或基本上平行于赤道平面，在与赤道平面不同的距离处具有增加的弹性。

摘要： The invention relates to an artificial hip joint, in which the surfaces of both the socket and the ball of the joint are in the form of rotational bodies (rotational surfaces) deviating from the normal spherical shape. The rotational surfaces are in the form of Pascal's curve or screw rather than being spherical. In addition, provision is made such that an angular deviation .alpha. is present between the axis of the femoral throat of the thigh and the rotary axis of the ball of the joint when viewed from the top, such deviation preferably equal to 10.7.degree..+-.3.degree..
