Abstract: An intermediate body is for a bone implant for replacement of an osseous area. The intermediate body has a base body and a seat which extends axially in the base body and is surrounded by a wall of the base body. The intermediate body is designed to receive and surround an end portion of an intramedullary implant part. A clamp device is assigned to the seat. A clamp component is arranged on the wall of the base body surrounding the seat. In order to clamp, the end portion is inserted beforehand into the seat relative to the wall of the base body. The wall then surrounds the seat and the inserted end portion is movable towards the seat and in the process clamps the end portion in the seat. An implant arrangement is provided with the intermediate body.

Abstract: A knee arthrodesis implant has a femur nail and a tibia nail. A connecting module has two longitudinally separated half shells that when connected form a passage. One end of the connecting module is coupled to a femur nail neck and the other end is coupled to a tibia nail neck. The half shells have a plurality of corresponding recesses extending perpendicularly to the passage. Each recess receives a tensioning screw, and tightening the tensioning screws couples the femur and tibia nail necks to the connecting module by holding the femur and tibia nail necks within the passage by frictional contact. Each of the two half shells is angled along its length, an angle of one of the half shells corresponding to an angle of the other of the half shells, allowing the tibia nail and femur nail to extend from the passage at an angle from one another.

Abstract: A modular joint prosthesis includes a nail for insertion into a bone marrow canal, the nail having a nail neck. A neck piece has a proximal end, a middle shaft portion defining a longitudinal axis, and a distal end with a conical pin to which a slip-on joint ball can be attached. The proximal end of the neck piece has a helmet-shaped receiving head that includes an insertion opening for insertion of the nail neck or a module connector, a slot extending in the direction of the longitudinal axis, and corresponding recesses positioned on either side of the slot and extending perpendicularly to the longitudinal axis. The corresponding recesses receive a tensioning means which, in a tensioned state, clampingly fixes the nail neck or the module connector in the receiving head by frictional engagement in a jaw-like manner by application of tightening torque sufficient to prevent axial displacement and rotation.

Abstract: A knee arthrodesis implant has a femur nail inserted in the bone marrow canal of the femur, and a tibia nail inserted in the bone marrow canal of the tibia, the nails being rigidly connected to each other by a connecting means. The problem of providing a knee arthrodesis implant having increased modularity as the result of increased length variability, having a reduced number of parts, and allowing simplified modification is addressed.

Abstract: A fixing element, in particular a peg, for fixing bone fragments, ligaments or the like, has at least two outer sub-elements which divide the fixing element in the longitudinal direction with respect to a separating surface between the at least two outer sub-elements. The at least two outer sub-elements are of such a configuration and are so arranged relative to each other that the fixing element is adapted to be transferred from a compact condition into a laterally or radially expanded condition. The fixing element is of a dovetail-like configuration at its proximal end for coupling to an instrument for holding and introducing the fixing element.

Abstract: A fixing element, in particular a peg, for fixing bone fragments or the like has at least two outer sub-elements extending parallel to each other and an expansion element. The sub-elements and expansion element are of such a configuration and so arranged relative to each other that the fixing element is to be transferred by means of the expansion element from a compact condition into an expanded condition. The two sub-elements define a cavity for the expansion element and have sliding surfaces for the expansion element. The sliding surfaces extend parallel to the longitudinal axis of the fixing element and, in the compact condition of the fixing element, are at a mutual spacing smaller than the mutual spacing of sliding surfaces of the expansion element, that also extend parallel to the longitudinal axis of the fixing element.

Abstract: An endoprosthesis for replacing osseous areas in the diaphysial and metaphysial region of a bone and for connecting separate segments of the bone includes at least one intramedullary securing member and an intermediate member having at least one end region and being divided longitudinally into two detachably connected part elements. Each at least one end region defines a respective recess so that when the two part elements are connected together, each at least one end region forms an axially extending passage that retains one of the at least one intramedullary securing members.

Abstract: The invention concerns an endoprosthesis (1) for replacing osseous areas in the diaphysial and metaphysial regions of an elongate bone, said endoprosthesis comprising an intermediate member (2) and devices (3, 4, 20, 21) for securing the latter in the intramedullary area. The intermediate member (2) is divided longitudinally, the interconnected part elements (2.1, 2.2) of the intermediate member (2) each forming with a recess (12.1) provided at their end regions an axially extending passage (12) through which an intramedullary securing device (3, 4, 20, 21) passes.

Abstract: A modular artificial hip joint includes a head part and at least one shaft part. The shaft part, which can be driven into the bone and forms the distal region, is connected to the distal end of the head part by insertion, preferably by means of an insert cone. A first screw or tie rod, guided through an axial bore in the head part, can be screwed into the threaded bore in the shaft part. In order to guide a second screw for separating the conical insert connection between the individual components of the artificial joint, the bore in the head part is threaded and has a diameter which is greater than the diameter of the threaded bore in the shank part.

Abstract: An osteosynthetical fixing element, for the fixing of a bone implant, includes an accommodating body which is adapted to be introduced into a bone bore-hole and an expanding body, where, as a result of the driving-in of the expanding body into a longitudinally directed opening having a continuous wall, the accommodating body is radially expandable by a wedge effect. The accommodating body is sub-divided in the longitudinal direction, and includes at least two sub-elements which form a shaft with a cavity and are separate from one another or are connected to one another so as to be moveable in such a manner that as a result of the driving-in of the expanding body into the cavity, the accommodating body is expandable, substantially over its entire length, as a result of the mutual wedge effect of the accommodating body and expanding body.
