ABSTRACT:
Artificial disc replacements (ADRs) use articulating components to permit normal spinal movement(s). According to the invention, an ADR situated between upper and lower vertebral bodies comprises a first endplate affixed to one of the vertebral bodies providing a first articulating surface having a first radius of curvature, a second endplate affixed to the other one of the vertebral bodies providing a second articulating surface having a second radius of curvature which is different from the first radius of curvature, and a spacer component having opposing surfaces that cooperate with the first and second articulating surfaces. In the preferred embodiment, the first endplate is affixed to the upper vertebral body, the first articulating surface is concave, the second endplate is affixed to the lower vertebral body, the second articulating surface is convex, and the first radius of curvature is larger than the second radius of curvature. The spacer may include a surface that congruently cooperates with the first and/or articulating surface(s).
