Abstract

See full text

An intervertebral implant for insertion between adjacent vertebral bodies is provided. The intervertebral implant can include a first component. The first component can have a first articulating surface, which can be generally convex. The intervertebral implant can include a second component, which can be generally in the shape of a toroid. The second component can have a second articulating surface. The second articulating surface can be generally concave and articulable with the first articulating surface for retaining motion between the first and second vertebra. The second articulating surface can have a larger radius of curvature than the first articulating surface such that a portion of the first articulating surface extends into an aperture defined by the generally toroid shape.
