摘要： Disclosed is an intervertebral disk prosthesis comprising an essentially hollow cylindrical base element (1) which is provided with a casing (2) that is embodied as a bellows, a top end (3), a bottom end (4), and a central longitudinal axis (5), an upper apposition plate (6) which is disposed perpendicular to the longitudinal axis (5) at the top end (3) of the base element (1) and rests on the base plate of a vertebra, and a lower apposition plate (7) that is arranged perpendicular to the longitudinal axis (5) at the bottom end (4) of the base element (1) and leans on the cover plate of a vertebra. The casing (2) that is embodied as a bellows is configured as a spring element having a defined spring rate. Said structure largely approaches the function and purpose of a natural intervertebral disk.

摘要： The invention relates to a vertebral disc or intervertebral disc prosthesis comprising: A) an upper apposition plate (1) that is suited for placing against the base plate of a vertebral body; B) a lower apposition plate (2), which is located at a distance from the upper apposition plate and which is suited for placing against the cover plate of a vertebral body; C) a number of elastic means (3) that are placed between both apposition plates (1, 2) in the peripheral areas (4) thereof so that both apposition plates (1, 2) can elastically move relative to one another, and; D) a central axis (5) that is essentially perpendicular to both apposition plates (1, 2). Said elastic means (3) are formed or arranged in such a manner that the vertebral disc has, by and large, an asymmetric rigidity.

摘要： The invention relates to an intervertebral disk prosthesis or nucleus replacement prosthesis comprising a biocompatible envelope (1) containing a hardenable, free-flowing mass (2) which, in turn, contains monomers, comonomers, homopolymers, oligomers or mixtures thereof. The hardenable, free-flowing mass located inside the envelope (1) is hardened in situ.

摘要： The invention relates to a damping element (1) comprising: (A) two spring elements (2; 4), which are coaxial or parallel to a longitudinal axis (3), and connecting parts (5; 6), which can be connected to the spring elements (2; 4) while being axially located at the ends thereof, whereby; (B) the first spring element (2) has a spring rate F; C) the second spring element (4) has a spring rate f, whereby; D) spring rates F and f differ from one another. The invention also relates to a device for stabilizing adjacent vertebral bodies comprising: A) N pedicel screws or pedicel hooks (12), whereby N ≥ 3; B) of which at least one pedicel screw or one pedicel hook (12) comprises a holding means (13), which simultaneously enables two parallel longitudinal fixing elements (7) to be held, and; C) an element (14) that functions as a spring and is provided for fixing between the at least one pedicel screw or pedicel hook (12), which is provided with holding means (13), and another adjacent pedicel screw or pedicel hook (12).

摘要： The invention relates to an intervertebral disk prosthesis or a nucleus replacement prosthesis, comprising an at least partially flexible jacket (3, 4, 5) that encloses a cavity (2) having a variable shape. The jacket (3, 4, 5) is at least partially configured as a semipermeable membrane (3) for a solvent so that a solution of a substance contained in the cavity (2) can adapt its concentration and its volume to the external load conditions according to the principle of reverse osmosis.

摘要： Disclosed is an intervertebral prosthesis or nucleus replacement prosthesis (1) comprising a longitudinal, elastic, coilable body (2), a first, outer end (3), a second, inner end (4), and a longitudinal central axis (5). The cross section (10) of the body (2), which is perpendicular relative to the central axis (5), decreases towards the second, inner end (4).
