摘要: A prosthetic is provided for replacing a vertebral disc. The prosthesis can comprise first and second endplates formed of a ceramic material, each including an articulating contact surface and a bone facing surface. The contact surface of the first endplate can have a shape complementary to the contact surface of the second endplate, thereby facilitating articulation of the first and second endplates while in contact with one another. The device can further include at least one non-ceramic bone attachment element mated with at least one of the bone facing surfaces, such that the bone attachment element covers less than a full area of the bone facing surface.
