Setting instrument () for a hip socket or shoulder socket inlay, having a handle part () and a suction element () that can be brought into sealing contact with the joint surface. The suction element () comprises a flexible molded part () matched to the joint surface, which molded part is deformable by a pulling element () in such a way that, when applied to the joint surface, an (increased) partial vacuum is formed between the joint surface and the flexible molded part ().

Instrument for handling a joint component by way of a vacuum

An instrument for handling a joint component of a joint prosthesis, which joint component includes a joint surface, includes a grip portion, a suction element in the form of a suction cup with an air-vent opening, the suction cup being placeable in a sealing manner against the joint surface, and a pressure-relief valve associated with the air-vent opening of the suction cup. The pressure-relief valve is coupled to an actuating element which is arranged so as to be movable in the region of the grip surface of the grip portion and, when gripped with one hand, is actuatable with a finger or the thumb of that hand, so that on actuation of the actuating element the valve is lifted away from the air-vent opening.

Accessory for implantation of a hip joint endoprosthesis, with a manipulation cup, a manipulation joint head with means for orienting the manipulation cup in the acetabulum, and with a device to represent the correctly oriented position of the manipulation cup such that by means of this device a bone-milling cutter and an impact instrument can then oriented appropriately for placement of the prosthesis cup.

Tibial component () of a knee-joint endoprosthesis with a flat tibial bearing surface (), a bearing body () that is slidably seated thereon and comprises two concave bearing dishes () in which a femoral component can be movably seated, and with a rotational guide means that guides the rotation of the bearing body () on the tibial bearing surface () about an axis () perpendicular thereto. The guide means comprises a bearing post () in the form of a regular cylinder that stands upright on the tibial bearing surface () and has at least one projection () extending radially outward. The bearing post so constructed can be inserted into a post receptacle () that is formed on the underside of the bearing body () with a receiving groove () corresponding to the post projection (). The at least one post projection () extending radially outward is spaced apart from the free end () of the post.

Tibial component of a knee-joint endoprosthesis

A knee joint prosthesis (1) comprises a tibia part (1) having a tibia bearing surface (10) and a bearing body (3) which is slidingly displaceably journalled on the tibia bearing surface (10) and which has bearing scallops (31) on its side which is remote from the tibia bearing surface (10). Furthermore, it comprises a femur part (5) which is movably arranged on the bearing scallops (31) of the bearing body (3) as well as comprising a guide piece (2) which is arranged to be rotationally fixed relative to the tibia part (1) and which permits only a displacement of the bearing body (3) in the sagittal direction relative to the tibia bearing surface (1). Furthermore, it comprises a coupling member which cooperates both with the guide piece (2) and with the femur part (5) and permits a rotation of the femur part (5) on the bearing body (3). The coupling member has a rotatably journalled pin (4) which extends in the direction of the longitudinal axis (14) of the tibia part (1) or of an axis of rotation parallel to it or in the direction of an axis which is inclined relative to the longitudinal axis of the tibia part (1) or to an axis of rotation parallel to it.
