摘要： An improved artificial disc has a superior and inferior member. The superior member has an upper body portion and a flange portion for positioning and attachment to an upper vertebral body. The inferior member has a lower body portion and a flange portion for positioning and attachment to a lower vertebral body. The upper body portion and the lower body portions, when positioned in a disc space between the upper and lower vertebral bodies and affixed to a respective vertebral body at the flange portion, are independently movable relative to the other along complimentary bearing surfaces on each of the superior and inferior members. The complimentary bearing surfaces are self-aligned by a magnetic attraction force generated by at least one first permanent magnet in either the inferior or superior member.

摘要： A prosthetic disc for insertion between adjacent vertebrae includes a core having upper and lower curved surfaces, upper and lower plates, and peripheral restraining structure on at least one of the upper plate, the lower plate and the core. Each plate has an outer surface which engages a vertebra and an inner curved surface which slides over the curved surface of the core. The peripheral restraining structure serves to hold the core against a curved surface of at least one of the plates during sliding movement of the plates over the core.

摘要： A prosthetic disc for insertion between adjacent vertebrae includes upper and lower plates, a core disposed between the plates, and at least one projection extending from at least one of the upper and lower curved surfaces of the core into at least one recess of one of the inner surfaces of the plates. The recess is oversize with respect to the projection to allow sliding movement of the plate over the core while retaining the core between the plates during such sliding movement. The projection(s) may include a rod extending through an axial hole in the core, multiple surface features of the core, or the like.

摘要： The invention relates to a prosthesis for replacing a joint connection, wherein like magnetic fields from the condyle 10, socket 12 and joint collar 14 overlap in such a way that the repulsive forces generate a suspended state of the condyle 10 in the bearing and the damping effect is maximized. The invention is also directed to a method for replacing a bone junction in a mammal, wherein the prosthesis is fastened to the articular bone and repulsive forces generate a levitated state of the condyle 10 under load.
