Abstract
An interbody device includes a solid interior and a non-linear body with opposed top and bottom abutment surfaces that are asymmetrically convex, the device being sized and shaped to be operably positioned between a pair of opposing vertebrae for support and/or fusion. The non-linear body has opposed first and second sides, the first side exhibiting a substantially convex profile and the second side exhibiting a substantially concave profile when viewed from the top or bottom, resulting in a arc- or kidney-shaped configuration. Furthermore, both sides include surfaces that are concave running from the top to the bottom and further include channels. The top and bottom surfaces may include ridges or teeth for facilitating positioning, attachment and fusion to bone.
