摘要： The disclosure provides a joint replacement coupling comprising joint members with opposing joint surfaces, wherein one of the members has a magnetic portion therein which comprises an array of magnets, and the other of the members has a conduction portion therein that comprises a conductive surface. The magnets are arranged to produce a magnetic field that contacts the conduction portion. The conduction portion is optionally positioned so that at least a portion of the conductive surface contacts the magnetic field so that relative motion between the opposing joint surfaces induces current loops in the conductive surface and produces a repulsive force against the magnetic portion, thereby reducing friction between the joint surfaces, optionally separating the joint surfaces.

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： 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.
