    摘要： A buffer (10) for placement in a human knee between the femur and tibia comprises an outer sack (14) formed of a pliable material and having a one-way valve (22), a generally circularly shaped inner ring (16) received within the outer sack (14), and a friction reducing fluid (18) received within the outer sack (14) via the one-way valve (22). The inner ring (16) includes top and bottom surfaces (38,40) angled inwardly with respect to each other, such that the ring (16) is generally concave. The buffer (10) is configured for insertion between the femur and tibia so as to at least partially prevent the bones from contacting each other, which reduces the pain and discomfort associated with a loss of articular cartilage (12). The buffer (10) is arthroscopically inserted in the knee using an especially designed sleeve (20) configured for support of the buffer (10) during insertion.

    摘要： The invention relates to a surgical implant that provides an artificial diarthroidal-like joint, suitable for use in replacing any joint, but particularly suitable for use as an intervertebral disc endoprosthesis. The invention contains two rigid opposing shells, each having an outer surface adapted to engage the surfaces of the bones of a joint in such a way that the shells are immobilized by friction between their outer surfaces and the surfaces of the bone. These outer surfaces are sufficiently rough that large frictional forces strongly resist any slippage between the outer surface and the bone surfaces in the joint. They may be convex, and when inserted into a milled concavity, are immediately mechanically stable. Desirably, the outer surfaces of the shells are adapted to allow for bony ingrowth, which further stabilizes the shells in place. The inner surfaces of the shells are relatively smooth, and adapted to slide easily across a portion of the outer surface of a central body disposed between the shells. The central body has a shape that cooperates with the shape of the inner surface of the shell so as to provide a range of motion similar to that provided by a healthy joint. A flexible sheath extends between edges of the opposing shells. The inner surface of this sheath, together with the inner surfaces of the rigid shells, defines a cavity encasing the central body. At least a portion of this cavity is filled with a fluid lubricant, further decreasing the frictional force between inner surfaces of the shell and the surface of the central body.

    摘要： An artificial intervertebral disk, insertable between two adjacent vertebral bodies of a patient and joining the two adjacent vertebral bodies an articulated manner, includes an intermediate element embodied as an elastic ring and is inserted into one respective molded portion of two outer elements configured as metal plates. The outer elements are joined to the bones of the vertebral bodies via anchoring pins, especially titanium anchorings previously known in hip endoprosthetics. The radius of the concave molded portion is greater than the diameter of a circular cross-sectional area of the intermediate element such that compression of the intermediate element caused particularly by the patient's movement allows for a defined deformation.
