    Abstract: Porous biocompatible structures suitable for use as medical implants and methods for fabricating such structures are disclosed. The disclosed structures may be fabricated using rapid manufacturing techniques. The disclosed porous structures has a plurality of struts and nodes where no more than two struts intersect one another to form a node. Further, the nodes can be straight, curved, portions that are curved and/or straight. The struts and nodes can form cells which can be fused or sintered to at least one other cell to form a continuous reticulated structure for improved strength while providing the porosity needed for tissue and cell in-growth.

    Abstract: Joint prostheses in which one joint partner is configured as a socket and the other joint partner is configured as a ball head, said ball head being rotatably mounted in the socket, are used, in particular, as shoulder joint and hip joint prostheses. The press fit connection, in particular, conical pressing, is also used as a technique for connecting metallic or ceramic ball heads to the cone. To this end, the ball head provided with a conical boring is placed on the cone. After placing the ball head on the cone, the ball head is subjected to an impact in order to fix the two components. To obtain a conical pressing, the joining surfaces of the boring in the ball head and of the cone must be machined with extreme precision, otherwise the durability of the conical pressing is jeopardized by a non-uniform introduction of force into the ball head or into the pivot. If the ball head is made of ceramic, fissuring can result due to stress peaks in the material, and in the worst case scenario, can lead to a destruction of the ball head. According to the invention, a coupling element (5) is thus provided which is inserted between the cone (5) and the ball head (3) of the press fit connection (1) and whose elasticity and damping properties can be predetermined by the porosity thereof and by the structure of its surface.
