摘要：
An apparatus for replacing a damaged spinal disc in a spinal column includes a first retaining device having an outer surface engageable with a first vertebra of the spinal column and an inner surface. A second retaining device has an outer surface engageable with a second vertebra of the spinal column and an inner surface. A resilient core has a first surface and a second surface. The first surface engages the inner surface of the first retaining device. The second surface engages the inner surface of the second retaining device. The resilient core has a tapered radially outer surface extending from adjacent the first surface to adjacent the second surface. The first retaining device may have a flange extending toward the second retaining device. A concave surface may extend between the first surface and the radially outer surface. The concave surface of the core may engage the flange when the apparatus is free of a load.
