摘要： A prosthetic implant for insertion into a cement filled intramedullary canal including a plurality of spacers formed from PMMA. The spacers include a body having a frontal portion and a trailing portion. The body of the spacers narrowing with distance from said frontal portion toward said trailing portion. The narrowing body of the spacers interrupting the flow of cement along the implant body as the body is inserted into a cement filled intramedullary canal. The narrowing trailing portion of the spacers cause the cement flow to smoothly re-attach to the implant body without creating substantial disturbances or vortexes in the cement.

摘要翻译： 一种用于插入包括多个由PMMA形成的间隔物的填充髓内髓质细管的假体植入物。 间隔件包括具有前部和后部的主体。 间隔物的主体随着从所述前部向所述后部的距离变窄。 当身体插入到水泥填充的髓内管中时，间隔物的狭窄体中断了植入体的水泥流动。 间隔物的较窄的后部使得水泥流平滑地重新附着到植入体上，而不会在水泥中产生实质的干扰或涡流。

摘要： A method for joining two or more segments of a bone implant comprises the steps of placing a plurality of thin layers of an intermetallic material between first and second segments of the bone implant and applying a mechanical load to the plurality of layers. In a subsequent step, the plurality of layers are ignited by applying an external activation energy thereto, the ignition heating the plurality of layers to a reaction temperature and causing the segments to become affixed to one another after cooling.

摘要： An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

摘要： An anchorage in tissue is produced by holding a vibrating element and a counter element against each other such that their contact faces are in contact with each other, wherein at least one of the contact faces includes a thermoplastic material which is liquefiable by mechanical vibration. While holding and then moving the two elements against each other, the vibrating element is vibrated and due to the vibration the thermoplastic material is liquefied between the contact faces, and due to the relative movement is made to flow from between the contact faces and to penetrate tissue located adjacent to outer edges of the contact faces. For liquefaction of the thermoplastic material and for displacing it from between the contact faces, no force needs to act on the tissue surface which is to be penetrated by the liquefied material.

摘要： An implant designed e.g. as a replacement for an articulating surface of a human or animal joint is secured to the bone tissue with the aid of a plurality of fasteners (3). The implant (2) comprises a bone side to be brought into contact with the bone tissue, which bone side is equipped with a plurality of fastening structures restricted to this bone side. The fasteners (3) comprise a distal and a proximal side, wherein the distal side is equipped for being anchored in bone tissue and the proximal side is equipped for being connected with one of the fastening structures of the implant (2). The distal sides of the fasteners (3) are anchored in the bone tissue of the appropriately prepared bone and the implant (2) is then attached to the anchored fasteners (3) by connecting the fastening structures with the proximal sides of the fasteners (3), wherein the implant (2) is pressed against the proximal sides of the anchored fasteners (3). The connection between fastening structures and proximal sides of the fasteners is a positive fit connection, a material fit connection and/or a force fit connection.

摘要： An expandable assembly for insertion into an intervertebral space is presented. The assembly, in particular aspects, includes an elongate body comprising an upper portion and a lower portion, wherein the elongate body defines an internal longitudinal channel extending from a proximal opening to a distal cavity. The assembly may include an expander that is sized and shaped for insertion into the distal cavity, thereby selectively expanding the upper portion away from the lower portion. The elongate body may also include one or more bone graft windows a cap that is sized and shaped for insertion into the proximal opening.
