    摘要： The acetabular cup prosthesis has a metal socket having a socket shell for receiving a spherical joint head as well as a plastic ring which covers the equatorial edge surface of the metal socket and which has an inner diameter corresponding to the inner diameter of the shell. In the event of a dislocation of the joint head, the polished surface of the joint head contacts the plastic ring to deform the ring without imposing a point load on the metal joint head.

    摘要： The ligament anchor is used for fastening an artificial ligament in a bone. The ligament anchor is formed of a clamp sleeve which tapers on the outside and is deformable radially to a smaller inner diameter. The clamp sleeve has projecting saw tooth segments on the inside with steep flanks against the direction of loading for engaging in the inserted ligament. The clamp sleeve is supported by an anchoring sleeve which tapers internally and is inserted in the opening of the bone. For anchoring, the ligament is pulled outwards under pressure against the direction of loading and the clamp sleeve is pressed into the anchoring sleeve in the direction of loading until the saw tooth elements embrace and hold the ligament such that under the built-up pressure and the ligament tension in the direction of loading, self locking of the sleeves take place.

    摘要翻译： 韧带锚固件用于将人造韧带紧固在骨中。 韧带锚固体由夹紧套筒形成，夹紧套筒在外侧逐渐变细并可径向变形成较小的内径。 夹紧套筒在内侧具有突出的锯齿段，陡峭的侧面抵抗装载方向，用于接合插入的韧带。 夹紧套筒由固定套筒支撑，锚定套筒内部渐缩并插入骨头的开口中。 为了锚固，将韧带在压力下沿着装载方向向外拉出，并且夹紧套筒沿加载方向被压入锚固套筒中，直到锯齿元件包围并保持韧带，使得在建立的压力和 韧带张力在装载方向上发生袖套自锁。

    摘要： The implanted is constructed with a metal base element and a plastic part which is elastically mounted on the base element and carries a metal grid structure for the ingrowth of bone tissue. The elastic mounting is provided by a prop which extends from a body portion of the plastic part into a depression in the base element. The prop is received in the depression with lateral play to not only hold the mutually facing surfaces of the base element and plastic part from each other but to permit lateral play. The floating suspension permits inevitable micromovements between the metal implant and the plastic part to be absorbed and not transmitted directly to the bone tissue which grows into the metal grid structure.

    摘要： The artificial crucial ligament is formed of a plurality of tubes which are disposed in concentric relation to define a stem. Alternating tubes extend from the stem to form two branches. The tubes are made of textile structures to impart flexibility and longitudinal elasticity to the ligament. In one embodiment, the tubes are made of a braided construction.

    摘要： The anchoring surface of the bone implant is provided with villi (depressions or projections) devoid of corners and edges. The villi are of generally conical shape with transition surfaces merging into the base level of the anchoring surface. The villi allow implanting in a bone without cement since bone tissue is allowed to grow into or around the villi.
