Abstract
An intervertebral implant and associated method. The intervertebral implant can include a first component having a first articulating surface and a first bone engagement surface for engaging a first vertebra, and a second component having a second articulating surface and a second bone engagement surface for engaging a second vertebra adjacent to the first vertebra. The first and second articulating surfaces can articulate with each other for substantially replicating a natural spinal movement. The first and second bone engagement surfaces can define an outer surface substantially shaped as an envelope of two intersecting cylinders. In one aspect, the first and second articulating surfaces can have substantially equal radii of curvature in a coronal plane and different radii of curvature in a sagittal plane.
