摘要:
A prosthetic disc (10) for insertion between adjacent vertebrae includes a core (16) having upper and lower curved surfaces (48,50), upper and lower plates (12,14), and peripheral restraining structure (26) on at least one of the upper plate (12) the lower plate (14) and the core (16). Each plate has an outer surface (18), which engages a vertebra and an inner curved surface (24) which slides over the curved surfaces (48,50) of the core (16). The peripheral restraining structure (26) serves to hold the core (16) against a curved surface (24) of at least one of the plates during sliding movement of the plates over the core.

摘要:
An orthopaedic implant (10) such as an elongated nail or a joint prosthesis (10) includes a superparamagnetic material (22,24,26). The material can be provided in a hole in the implant (10), for example as a coating or at least partially filling the hole, or on an external surface of the implant close to the hole.
摘要:
The invention relates to a prosthesis for replacing a joint connection in which identically polarized magnetic fields of the condyle (10), joint cavity (12), and joint collar (14) are superimposed on each other 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 also relates to a method for replacing a bone joint of a mammal. In said method, the prosthesis is fastened to the joint bone, and repulsive forces generate a levitated state of the condyle (10) under load.
