摘要:
One embodiment of the present application includes a spinal disk prosthesis with one end portion to form a load transmitting relationship with one vertebra of a patients spine and another end portion to form a load transmitting relationship with another vertebra of the patients spine. A tube connects the end portions together and a damping material is positioned inside the tube. The end portions each include a magnet to generate a corresponding magnetic field. These magnetic fields are oriented to provide a repulsive force between the end portions to provide a magnetic bearing.
