A prosthetic device for insertion into an intervertebral space may include
a first articulating element formed of a ceramic material and a second
articulating element configured to cooperate with the first articulating
element to permit articulating motion. The second articulating element
also may be formed of a ceramic material. A first polymer component may
be joined to the first articulating element at a first ceramic-polymer
interface and a second polymer component may be joined to the second
articulating element at a second ceramic-polymer interface. A method of
manufacturing the disc is also disclosed.
